Single vs. Double Garage Door: Which Is Right for Your Two-Car Garage? (Complete Utah Guide)

For a standard two-car garage in Utah, most homeowners choose one 16-foot double door for lower cost, easier daily use, and simpler maintenance – but two 8- or 9-foot single doors offer better wind resistance, independent operation, and more curb appeal options. The right choice depends on your budget, home style, Utah weather exposure, HOA rules, and how you use your garage. Advanced Door – family owned since 1994, the only company in Utah offering a lifetime warranty on parts and labor – installs both configurations across Utah.

Quick Comparison: Single vs. Double at a Glance

Before diving into the details, here is the side-by-side comparison that answers the most common questions homeowners ask when deciding between one double garage door or two single doors.

Both configurations are excellent choices when properly installed. The right one depends on your home, your budget, and how you use your garage every day. Let’s break down each factor in detail.

Standard Sizes for Each Configuration

Understanding the size differences between single and double garage doors helps you plan for clearances, vehicle fit, and structural requirements.

Double garage door (one door for two-car bay):

• Standard width: 16 feet (most common in Utah)
• Other widths: 14, 15, and 18 feet (18 ft for oversized or three-car center bays)
• Standard height: 7 feet (residential) or 8 feet (increasingly common in newer Utah construction)
• Typical weight: 250-400+ pounds depending on material and insulation

Single garage door (one door per car bay):

• Standard width: 8 feet or 9 feet (9 ft is more common in Utah new construction)
• Other widths: 7 and 10 feet (10 ft for trucks, SUVs, and workshop access)
• Standard height: 7 feet or 8 feet
• Typical weight: 100-200 pounds each depending on material and insulation

Structural note: Two single doors require a center post (also called a center column or pier) between the openings. This post is structural – it supports the header beam above the garage opening. A double door has no center post, which means the entire 16-foot span relies on the header beam alone. This structural difference affects wind resistance, cost, and framing requirements.

Cost Comparison: Purchase, Installation, and Long-Term

Cost is typically the first question homeowners ask, and the answer is clear: one double door costs less upfront than two single doors. Here is why.

Why two singles cost more:

• Two doors instead of one: Even though each single door is smaller, two of them cost more combined than one double door of comparable quality
• Two sets of hardware: Double the tracks, springs, hinges, rollers, brackets, and weatherstripping
• Two openers: You need a separate garage door opener for each single door
• Additional framing: The center post between two singles requires structural framing, concrete footings, and finishing
• More installation labor: Two complete installations take more time than one

The typical cost difference ranges from 15-30% more for two single doors versus one double, depending on the door material, insulation level, and opener quality. For budget-conscious homeowners, a double door is almost always the more economical choice.

Long-term cost considerations:

• Maintenance: Two doors means twice the springs to lubricate, twice the weatherstripping to replace, and twice the tune-ups
• Spring replacement: Double doors use larger, more expensive torsion springs, but you only have one set. Singles use smaller springs, but you maintain two sets. Over 15-20 years, the total spring replacement cost is often comparable
• Opener replacement: Openers typically last 10-15 years. With two singles, you will replace two openers over that cycle instead of one
• Replacement: If a double door panel gets damaged, the replacement panel for a 16-foot door costs more than an 8- or 9-foot panel. But if you need to replace an entire door, one double is cheaper than matching two singles (see “Repair and Replacement” section below)

Curb Appeal and Architectural Style

Your garage door is one of the most visible elements of your home’s exterior – it can account for up to 30-40% of your home’s front-facing surface. The configuration you choose has a major impact on curb appeal.

When two single doors look better:

• Traditional and craftsman homes: Two carriage-house style singles with decorative hardware create the classic look of an old carriage barn. This style dominates Utah neighborhoods like the Avenues in Salt Lake City, older sections of Ogden, and historic Logan homes
• Colonial and farmhouse styles: Two symmetrical singles frame the garage facade beautifully and balance the home’s proportions
• Narrow facades: On homes where the garage faces the street on a narrow lot, two smaller doors can look more proportional than one wide expanse
• Mixed materials: Two singles allow you to add character with a decorative center post, different panel patterns, or accent lighting between the doors

When one double door looks better:

• Modern and contemporary homes: A single wide flush panel or full-view glass door creates the clean, unbroken lines that define modern architecture. This style is popular in Utah’s newer developments in Draper, Daybreak, and Vineyard
• Ranch-style homes: A well-proportioned double door often suits the long, horizontal lines of a ranch home better than two narrow singles
• Wide facades: On homes with a broad front, a double door fills the space confidently without looking cramped
• Statement doors: If you want your garage door to make a visual impact with a bold material, pattern, or full-view glass design, a single wide door maximizes that effect

Wind Resistance and Utah Weather Performance

Wind resistance is one of the most important factors for Utah homeowners – and it strongly favors two single doors in most cases.

Why singles are stronger in wind:

A 16-foot double door has 112+ square feet of surface area exposed to wind as a single unsupported panel. An 8-foot single door has roughly 56 square feet – half the wind load. More importantly, two singles have a center post between them that provides structural support the entire way from foundation to header.

During high-wind events, double doors are more prone to:

• Bowing inward: The center of a 16-foot door can flex under sustained wind pressure, which can pop the door off its tracks
• Track failure: Wind pressure pushes the door against the tracks unevenly, increasing wear and risk of derailment
• Complete failure: If a double door blows in, the entire garage opening is compromised. If one single door fails, the other side remains intact

Wind reinforcement options for double doors:

If you prefer a double door but live in a wind-prone area, reinforcement can close the performance gap:

• Horizontal struts: Steel C-channel struts bolted across the interior of each panel stiffen the door against bowing
• Wind-load rated doors: Some manufacturers offer double doors rated for specific wind speeds, with built-in reinforcement and heavier gauge steel
• Vertical reinforcement: End stiles and center stiles add vertical rigidity

These upgrades add cost but can make a double door viable even in Utah’s windiest locations. Learn more about reinforcement options in our struts and reinforcement guide.

Snow load and cold weather:

Utah’s Wasatch Front and mountain communities receive significant snowfall. Both configurations handle snow load similarly since the doors hang vertically, but bottom seals and weatherstripping performance differ slightly. Two single doors have more total linear feet of bottom seal and side weatherstripping, which means more potential entry points for drafts and moisture – but also more isolation between garage sections during extreme cold. For cold-weather garage door performance, see our winter garage door problems guide.

Insulation and Energy Efficiency

If your garage is attached to your home (as most Utah garages are), insulation directly affects your heating and cooling costs. Here is how the two configurations compare.

R-value comparison:

When you compare the same door model in single and double widths, the R-value per square foot of door panel is identical. An insulated steel door with polyurethane foam delivers the same R-value whether it is 8 feet or 16 feet wide.

However, two single doors have one advantage: the center post. That center column between two singles is typically a framed, insulated wall section with a much higher R-value than any garage door panel. This means the total thermal performance of a two-single configuration is slightly better because part of the opening is a fully insulated wall rather than a door panel.

Air infiltration:

Weatherstripping and bottom seals prevent drafts, and the configuration affects how much total seal perimeter you have:

• Double door: Approximately 48 linear feet of seal (16 top + 16 bottom + 7+7 sides + 2 tracks)
• Two singles: Approximately 60+ linear feet of seal (8+8 top + 8+8 bottom + 7+7+7+7 sides + 4 tracks) plus the center post seals

More seal means more potential for air leaks if seals are not maintained. But when properly installed and maintained, both configurations provide similar real-world thermal performance.

Convenience and Daily Use

How you actually use your garage every day matters more than most people expect when choosing a configuration.

Advantages of a double door for daily use:

• One button, one action: Press one button and the entire garage opens. No fumbling with two remotes or remembering which door to open
• Easier parking for wide vehicles: With no center post, you have the full 16-foot opening to maneuver. This is especially helpful for backing in trucks, SUVs, or vehicles with trailers
• Moving large items: Need to get a riding mower, ATV, boat, or furniture through? A 16-foot opening handles it. No center post in the way
• Workshop access: If you use your garage as a workshop, the full-width opening lets you work on larger projects with maximum airflow and access

Advantages of two singles for daily use:

• Independent operation: Open only the side you need. If one car leaves and the other stays, the closed side keeps the garage secure and insulated
• Energy savings: In Utah’s 100-degree summers and sub-zero winters, only opening half the garage dramatically reduces heat gain or loss
• Noise isolation: If you leave early while your spouse sleeps, opening one quiet single door is less disruptive than opening a full-width double
• Partial use: Use one side for your car and the other for a workshop, gym, or storage without ever opening the “car side” when you do not need to

Opener Requirements and Smart Features

Your garage door opener choice changes depending on the configuration, and the costs and capabilities differ significantly.

Double door opener requirements:

• One opener needed: A 16-foot double door requires one opener with sufficient horsepower – typically 3/4 HP or 1 HP for insulated steel doors
• Higher HP: Because the door is heavier (250-400+ pounds), you need a more powerful motor than a single-door opener
• Belt drive recommended: For a heavy double door, a belt drive or wall-mount opener provides quieter, smoother operation than a chain drive
• Single smart system: One opener means one myQ app connection, one WiFi setup, and one set of remotes to manage

Two single door opener requirements:

• Two openers needed: Each single door requires its own opener, typically 1/2 HP or 3/4 HP
• Lower HP per unit: Each door is lighter, so each opener works under less stress and may last longer
• Two smart systems: With two openers, you get independent smart control – open or close each door separately from your phone, set separate alerts, and give different access to different people
• Redundancy: If one opener fails, you still have full operation on the other side

Repair, Replacement, and Maintenance

The long-term maintenance and repair implications of your choice can significantly affect your total cost of ownership over 15-25 years.

When a double door needs repair:

• Both cars are stuck: If the door breaks, goes off track, or loses a spring, neither vehicle can get in or out until it is fixed. This is the single biggest practical downside of a double door
• Larger panels: If a panel gets dented or damaged, the replacement panel for a 16-foot door is larger and more expensive than an 8- or 9-foot panel
• Heavier springs: The torsion springs on a double door are under more tension and are more expensive to replace – though you only have one set
• Single point of failure: One track issue, one spring break, or one cable snap affects the entire opening

When a single door needs repair:

• The other side still works: If one door goes down, the other operates normally. You can still get one car in and out while waiting for repair
• Smaller parts, lower per-incident cost: Individual repair parts for single doors are generally less expensive
• Matching challenges: If you need to replace one entire door years later, finding an exact match for the remaining door can be difficult. Manufacturers change panel designs, colors, and textures over time
• Double the maintenance frequency: Two sets of springs, rollers, tracks, and seals to maintain

For maintenance schedules and tips for either configuration, see our complete maintenance guide.

Safety Considerations

Both configurations are safe when properly installed with modern safety features (photo-eye sensors, auto-reverse, manual release). However, there are safety differences worth understanding.

Double door safety factors:

• Weight: A 16-foot insulated steel door weighs 250-400+ pounds. If a spring breaks, this weight can cause the door to slam shut or become impossible to lift manually
• Spring tension: Double door torsion springs store significantly more energy than single door springs. Spring failure is more violent and dangerous
• Manual operation: In a power outage, manually lifting a 300+ pound door is extremely difficult and can be impossible for many people. Battery backup openers are strongly recommended
• Vehicle clearance: With no center post, children and pets have a wider area to walk through while the door is moving

Single door safety factors:

• Lighter weight: Each door weighs 100-200 pounds – much easier to operate manually in an emergency
• Lower spring tension: Springs are under less stress, making spring failure less violent (though still dangerous – never attempt DIY spring work)
• Center post: The post between two singles creates a clear boundary. However, it can also be a collision hazard if someone walks into it in the dark
• Independent sensors: Each door has its own photo-eye safety sensors, providing independent auto-reverse protection

For comprehensive safety information, see our garage door safety and security guide and battery backup guide.

HOA Rules and Building Codes in Utah

Before you commit to a configuration, you need to know what your community and local jurisdiction allow.

HOA restrictions:

Many Utah homeowners associations dictate garage door configuration as part of their architectural standards. Common HOA requirements include:

• Specific configuration: Some HOAs require two single doors for aesthetic consistency across the neighborhood. Others require a double door to match the original construction
• Approved colors and materials: Your HOA may limit your options regardless of configuration
• Architectural review: Converting from one configuration to another (e.g., replacing a double with two singles) almost always requires HOA approval
• Matching requirements: If you replace one of two single doors, the HOA may require the replacement to match the remaining door exactly

Building codes:

Utah follows the International Residential Code (IRC) with local amendments. Key code requirements that affect your configuration choice:

• Header sizing: A 16-foot double door requires a much larger structural header beam than an 8- or 9-foot opening. Converting from two singles to a double may require structural engineering and a building permit
• Fire separation: The wall between an attached garage and the living space must meet fire-resistance requirements. The center post between two singles contributes to fire separation; removing it requires verification that fire separation is maintained elsewhere
• Wind load: Some Utah jurisdictions require wind-load rated doors in certain areas. Meeting wind-load requirements is easier and less expensive with single doors
• Permits: Converting from one configuration to another typically requires a building permit due to the structural changes involved

Resale Value and Buyer Preferences

If you plan to sell your home within the next 5-10 years, consider what buyers in your market prefer.

General buyer preferences in Utah:

• Newer subdivisions (2010+): Most were built with double doors, and buyers expect the same. Changing to two singles may look out of place in the neighborhood
• Older neighborhoods (pre-2000): Many were built with two single doors. Buyers in these areas often prefer the traditional look of two singles with carriage-house styling
• Custom and luxury homes: Buyer preference varies by style. A modern custom home suits a dramatic double door. A mountain lodge or craftsman home calls for two singles with decorative hardware

According to the Cost vs. Value Report, garage door replacement consistently ranks among the top home improvement projects for return on investment. The configuration matters less than the quality and condition of the door – a beautiful, well-functioning garage door in either configuration adds value.

Utah-Specific Factors That Affect Your Decision

Utah’s unique geography, climate, and housing market create specific considerations that homeowners in other states do not face.

Wind corridors and canyon mouths:

Utah has some of the most concentrated wind corridors of any state. Homes near Point of the Mountain (Draper/Lehi), canyon mouths (Parley’s, Ogden, Weber, Provo), and open valleys (Cache Valley, Tooele Valley) experience regular high-wind events. In these areas, two single doors with the structural center post provide measurably better wind resistance. If your home faces the wind, this factor alone may drive your decision.

Temperature extremes:

Utah regularly swings from below zero in winter to triple digits in summer. These temperature extremes cause garage door materials to expand and contract. A 16-foot double door panel experiences more total expansion than an 8-foot single panel, which can affect fit, seal contact, and panel alignment over time. Proper installation with expansion gaps prevents most issues, but singles are inherently less affected by thermal movement.

Utah truck culture:

Utah has one of the highest rates of full-size truck and SUV ownership in the country. If you drive a full-size truck with extended mirrors, a 16-foot double door gives you the most maneuvering room – no center post to dodge. However, two 9-foot singles each provide ample clearance for even the widest trucks when parking straight in.

Outdoor recreation storage:

Skis, bikes, kayaks, ATVs, side-by-sides, and snowmobiles are standard garage residents in Utah. If you need to move large recreational equipment in and out regularly, a 16-foot double door is hard to beat. The unobstructed width accommodates trailers, side-by-sides, and boats that simply will not fit through an 8- or 9-foot single opening.

Builder-grade considerations:

Many Utah homes built between 2010 and 2020 received builder-grade garage doors that are now reaching their 5-10 year failure window. If you are replacing a builder-grade double door, this is the perfect time to evaluate whether switching to two singles makes sense for your situation. See our builder-grade upgrade guide for more on this topic.

When Two Single Doors Are the Better Choice

Choose two single doors when the following factors align with your situation:

• Your home is in a high-wind zone (Point of the Mountain, canyon mouth, open valley) and wind resistance is a priority
• Your home’s architecture demands it – craftsman, colonial, farmhouse, or traditional styles where two singles define the look
• Your HOA requires it – check before you buy
• You and your spouse have different schedules and value independent operation (open only your side when leaving or arriving)
• You use half the garage as a workshop, gym, or storage and rarely need to open that side
• You want redundancy – if one door breaks, the other side still works
• You are building new or doing a major remodel where the center post framing is part of the project anyway
• You prioritize safety – lighter doors are easier to operate manually in emergencies

When One Double Door Is the Better Choice

Choose one double door when the following factors describe your situation:

• Budget is a primary concern – one door, one opener, one installation is significantly less expensive
• You need maximum opening width for trucks, trailers, boats, ATVs, or other wide equipment
• Your home has modern or contemporary architecture where a wide, clean door line looks best
• You are replacing an existing double door and want to avoid the cost and complexity of converting to two singles
• Simplicity matters – one button, one opener, one maintenance schedule
• Your garage is not in a high-wind zone
• You use your garage as a workshop where the full-width opening provides maximum access and ventilation
• Your HOA requires a double door or the neighborhood standard is doubles

7 Common Mistakes When Choosing a Configuration

After installing thousands of garage doors across Utah, our technicians see these mistakes repeatedly. Avoid them and you will be happy with your choice for decades.

1. Choosing based on cost alone. Yes, a double door is cheaper upfront. But if you live in a wind corridor and your double door blows in during a storm, the “savings” evaporate instantly. Factor in your location, home style, and usage – not just the price tag.

2. Not checking the HOA first. We have seen homeowners order and even install a configuration their HOA does not allow, only to be forced to remove it and start over. Always get written HOA approval before signing a contract.

3. Ignoring wind exposure. Homeowners often underestimate how much wind their garage door faces. If your garage faces south toward the Point of the Mountain, west toward the prevailing winds, or sits at a canyon mouth, wind resistance should be a top-three factor in your decision.

4. Forgetting about future vehicle changes. If you currently drive sedans but plan to buy a truck, boat, or RV, a double door gives you more flexibility. Think 5-10 years ahead, not just today.

5. Converting without a structural assessment. Switching from a double to two singles (or vice versa) involves structural changes to the header beam, framing, and potentially the foundation. Always get a structural assessment before committing to a conversion. What looks simple can become complex and expensive.

6. Mismatching the neighborhood. If every home on your street has two single carriage-house doors and you install a modern full-view double, it may look stunning in isolation but jarring in context. Match the neighborhood unless you are intentionally creating a statement.

7. Underestimating the center post impact. The center post between two singles reduces your usable opening width. Two 8-foot doors with a 6-inch post give you two 8-foot openings separated by a 6-inch column – not one 16.5-foot opening. Make sure each individual opening is wide enough for your vehicles before choosing singles.

Frequently Asked Questions

Is it cheaper to get one double garage door or two single doors?

One double door is almost always cheaper. You save on the door itself, hardware, installation labor, and the opener (one instead of two). Two single doors typically cost 15-30% more than a comparable double door when you add up all the components. The exact difference depends on the door material, insulation level, and opener quality you choose.

Can I convert my double garage door to two single doors?

Yes, but it is a significant project. Converting requires adding a center post with structural framing and a concrete footing, modifying the header beam, installing new tracks and hardware for two doors, and adding a second opener. This is not a DIY project – it requires a structural assessment, a building permit in most Utah jurisdictions, and professional installation. The conversion cost is typically 30-50% more than a straight double-door replacement.

Which is better for wind – one double or two singles?

Two single doors are stronger in high-wind conditions. The center post between them provides structural support that a double door lacks. A 16-foot double door has roughly twice the wind-catching surface area as each single door. For Utah homes in wind corridors (Point of the Mountain, canyon mouths, open valleys), two singles with wind-load reinforcement offer measurably better wind resistance.

Do two single doors increase home value more than one double?

Neither configuration inherently increases home value more than the other. What matters most is that the door looks good, operates properly, and matches the home’s architectural style and neighborhood standards. A beautiful double door adds just as much value as two beautiful singles. Choose the configuration that fits your home – that is what adds value.

What happens if one of my two single doors gets damaged?

You repair or replace just the damaged door. The advantage is that the other side continues working normally. The challenge is finding an exact match for the remaining door – manufacturers change panel designs, colors, and textures over time. If you buy both doors together from the same production run, consider ordering an extra panel as a spare for future matching.

How wide should single garage doors be for trucks and SUVs?

For full-size trucks and SUVs, 9-foot single doors are the minimum recommended width. Most full-size trucks (F-150, Silverado, Ram 1500) are 6.5-7 feet wide with mirrors folded. A 9-foot door gives you 12-15 inches of clearance per side. If you have extended towing mirrors or frequently pull in at an angle, consider 10-foot single doors for extra margin.

Do I need two garage door openers for two single doors?

Yes. Each single door requires its own dedicated opener. You cannot operate two separate doors from a single opener. The upside is that two openers give you independent control – you can open one side without opening the other, and if one opener fails, the other side still works. See our opener installation guide for more details.

Should I match my garage door configuration to my neighbors?

Generally, yes – especially if you have an HOA or plan to sell your home within the next several years. Matching the neighborhood standard helps your home blend in and avoids potential HOA violations. However, if you are building a custom home or doing a major renovation, the “right” configuration is the one that fits your home’s architecture, regardless of what the neighbors have.
