What Are Standard Garage Door Sizes?

Understanding typical garage door sizes is crucial when buying a replacement door or installing one in a new house. It's challenging to categorize any one option as a normal garage door size given the range of dimension combinations, although some sizes are undoubtedly more prevalent than others. According to height and breadth, the following is the typical garage door size: 2

  •  7-8 feet high by 8-10 feet wide for a single garage door
  •  7-8 feet high by 16-18 feet wide for a double garage door
  • 10-14 feet high by 10-14 feet wide for a RV garage door

Garage Door Design Options

The size and configuration of your garage itself will determine the appropriate garage door size. The designs for garages range from little areas intended for a single vehicle to bigger, typical 2 car garage door sizes to possibilities for several vehicles.

If you purchased a pre-existing property, this choice was probably already made for you. But there are a number of things to take into account when building or modifying a house, such as:

  • Personal preference, style, and needs are based on a number of vehicles.
  • Aesthetics and how the garage façade will affect the appearance of your home. 
  • Practicality and the cost of maintaining multiple doors and an opener system.


Single Car Garage Door Dimensions

Suited for smaller garage spaces with room for only one vehicle, single garage doors most commonly measure either 7 or 8 feet in height and 8, 9, or 10 feet in width. The doors are suited for a single standard-sized car, SUV, truck, or van.


Two Car Garage Door Dimensions

Homes with multiple-vehicle garages will most commonly use a double-door option, measuring 7 or 8 feet in height and 16 or 18 feet in width. This option is also popular with those planning to use a portion of their garage as a workshop or storage space.


RV Garage Door Dimensions

Large doors are available for those with specialized needs, such as parking several vehicles or an RV. These oversized garage doors tend to be 10, 12, or 14 feet in both height and width.


Combination Garage Doors 

As seen in the graphic above, many garages use a combination of either multiple single doors or a single and double door. While these garage door designs offer more space and flexibility, they also require maintenance and upkeep of at least two separate openers and garage door systems.


Custom Garage Doors

If you’re having trouble finding the right pre-fabricated door to meet your needs, Door 48 can assist with the design and creation of custom wood and steel garage doors. Visit the Door 48 website or call Houston (832) 400 2992 Austin (512) 543-7324 for more information.


Standard Garage Door Thickness

The thickness of most garage door panels is about 1/8 inch. Depending on how you use your garage, insulation might or might not be necessary. You should think about installing insulation if you spend a lot of time in your garage. In addition to lowering energy expenses, properly placed insulation can keep your garage 12 degrees warmer in the winter and 25 degrees cooler in the summer.

How Often Should Commercial Garage Doors Be Replaced?
By Rabia Tingat February 20, 2026
If you manage a warehouse, service bay, loading dock, or retail backroom, your overhead doors are working harder than most people realize. They open and close dozens of times a day, take hits from forklifts, battle weather, and still need to seal and operate safely. So it’s natural to ask: how often should commercial garage doors be replaced? There isn’t one perfect number, because commercial doors “age” based on cycles, environment, and how well they’re maintained. Still, there are practical timeframes you can use for planning and budgeting. In most facilities, a commercial garage door lasts about 15–30 years, but high-cycle locations may need replacement much sooner—sometimes in 8–15 years—especially if safety, downtime, and energy loss become costly. This guide breaks down typical commercial garage door lifespan by door type, the signs that replacement is smarter than repair, and how to make a decision that protects operations. What Determines a Commercial Garage Door’s Lifespan? Before we talk timelines, it helps to understand what really wears out. In commercial settings, the door panels often survive longer than the moving parts. The parts that usually drive replacement decisions include: Springs and cables (cycle-related wear) Rollers and hinges (friction and alignment) Tracks (impact damage and shifting) Bottom seal and perimeter weathering Operator/motor compatibility and safety systems The biggest factor is usually cycle count—how many times the door opens and closes. A door at a busy dock might run 80–200 cycles per day, while a storage facility door might run 5–15 cycles. That difference alone can cut years off the system. Typical Replacement Timelines by Door Type Sectional steel overhead doors (common in warehouses) These are durable and repair-friendly. With consistent commercial door maintenance, many facilities get 15–25 years, sometimes more. If you run high daily cycles or deal with corrosion, replacement may come earlier. Rolling steel doors (often used for security) Rolling steel doors can last 20–30 years, but they need proper alignment and regular service. Heavy use and impacts can shorten lifespan. High-speed doors (fabric, rubber, or fast-acting sectional) High-speed doors are designed for cycle-heavy environments, but they may need major component replacement sooner due to constant motion and sensor reliance. Many operators plan for 10–15 years depending on environment and usage. Dock doors and loading bay doors Dock doors take the most abuse: pallets, trucks, forklifts, and constant openings. Even with good upkeep, dock door replacement planning often lands around 10–20 years, sometimes sooner in high-impact facilities. How Often Should Commercial Garage Doors Be Replaced in High-Traffic Facilities? If your door is part of daily operations—shipping, receiving, fleet service, or temperature-controlled movement—replacement schedules usually tighten. Here’s a realistic way to think about it: Low traffic (under 20 cycles/day): replacement often 20–30 years Moderate traffic (20–60 cycles/day): replacement often 15–25 years High traffic (60+ cycles/day): replacement often 8–15 years , depending on upkeep and damage High traffic doesn’t always mean the door panels fail. It means the system becomes costly to keep alive: frequent spring changes, constant roller wear, downtime from sensor or track issues, and growing energy loss from poor sealing. In these environments, replacement becomes less about age and more about operational efficiency. The Clear Signs It’s Time to Replace (Not Just Repair) A commercial door can be repaired many times, but at a certain point, repairs stop making sense. You’ll usually know replacement is near when you see these patterns. 1) You’re paying for repeated “same problem” repairs If you’re calling service repeatedly for: tracking issues roller failures cables slipping bottom seal tearing operator strain and limit problems …it’s a sign the door system is aging out or the structure is compromised. 2) Door panels are bent, cracked, or no longer sealing Panels that are bowed or dented can still open and close, but they often: scrape tracks leak air and pests increase operator load fail under wind pressure If sealing problems affect climate control, replacement can pay for itself faster than expected. 3) Your operator and safety features are outdated Modern facilities rely on photo eyes, edge sensors, monitored safety devices, and reliable reversing systems. If your door system can’t support safe operation consistently—or if parts are hard to source—an overhead door upgrade may be the safer choice. 4) Rust, corrosion, or rot is spreading Once corrosion starts affecting key areas (bottom sections, hinges, fasteners), repairs become temporary patches. Coastal areas and chemical-exposure environments reach this stage faster. 5) Downtime is costing more than the door This is the most business-focused indicator. If door breakdowns interrupt shipments, block bays, delay fleets, or create safety risks, replacement becomes a productivity decision—not just a maintenance one. Repair vs Replace: A Practical Decision Framework Instead of guessing, use this simple logic: Repair makes sense when the door is structurally sound, the issue is isolated (springs, rollers, sensor alignment), and service calls are infrequent. Replacements make sense when damage is structural, service calls are frequent, parts are hard to find, or energy/downtime costs keep rising. A common rule facility managers use: if you’re spending a large percentage of the door’s replacement cost every year just to keep it operating, replacement should be on the table. Even without exact percentages, you’ll feel it in recurring invoices and repeated disruptions. Commercial Door Maintenance That Extends Replacement Timing If you want to push replacement further into the future, maintenance matters more than brand. The best routine focuses on preventing friction, misalignment, and safety failures. What helps most: scheduled inspections (not just “fix when broken”) tightening hardware and checking track alignment replacing worn rollers before they damage tracks keeping seals intact to reduce strain and heat loss checking spring condition and balance regularly A well-maintained door often lasts years longer because it avoids the “domino effect” where one worn part damages several others. Examples: When Replacement Is the Better Business Move Example 1: Busy loading dock A distribution center runs dock doors constantly. Repairs are frequent, and trucks wait when a door jams. Even if the door is only 12 years old, replacement may be smarter because downtime affects deliveries and labor costs. Example 2: Climate-controlled warehouse A facility stores temperature-sensitive products. The door still works but leaks air badly and struggles to close smoothly. The energy loss and equipment strain may justify replacement earlier than expected. Example 3: Service bays for fleet vehicles A door with dented panels and worn tracks becomes a safety hazard. Even if it “works,” it’s risky around staff and vehicles. Replacing prevents injuries and property damage. Cost Factors to Consider (Beyond the Door Price) Replacement decisions aren’t only about purchase price. Consider: installation time and scheduling around operations upgrading the operator or controls insulation value and energy savings security improvements reduced maintenance and fewer service calls Sometimes a newer, better-sealing door can reduce heating/cooling loss enough to matter in monthly operating costs—especially for large openings. Conclusion So, how often should commercial garage doors be replaced? In many facilities, the realistic lifespan is 15–30 years, but high-traffic or harsh environments may require replacement closer to 8–15 years. The best time to replace is usually when repairs become repetitive, safety and sealing are declining, and downtime starts affecting daily operations. If you’re unsure, don’t wait for a failure. Plan ahead, evaluate cycle count and repair history, and treat replacement as an operational upgrade—not just a maintenance expense.
