Garage Door Sizes Guide
If you are in the market for a new garage door or upgrading an existing one, this guide should be able to help you figure out the proper door size for your garage to fit your vehicle and requirements.
Although standard residential garage door sizes are common knowledge in hardware stores, the exact sizing of your actual requirement will need some analysis. The recent trend points to people using garage space for activities other than just parking vehicles so more and more homeowners are choosing to have a larger garage.
55% of Americans spend 1 to 2 hours each week doing hobbies and home improvement activities inside their garage.
To give you a snippet of what will be discussed, here is the table of contents for your guidance.
To start, it’s important to highlight the factors that have the maximum effect in determining the size of a garage door. Below are the 4 major factors to consider when planning and designing your garage;
Type and size of the vehicle
The size of your garage door should not only be wide enough to accommodate your vehicle type but tall enough to fit any rooftop accessories like roof racks and cargo holders. Below are the average garage door sizes of each type of vehicle.
- Sedans and Cars — The typical vehicle for the average homeowner. Sedans are 6 feet to 6.5 feet wide and 16 feet to 18 feet long. The average height of sedans 4.5 feet to 5 feet but take note of luxury cars that have larger wheels and higher ground clearance.
- Sports Utility Vehicles, All Utility Vehicles, and Vans — The largest vehicle a typical family can own. Most will be 6 feet to 7 feet wide and 16 feet to 19 feet long. Height will vary between 5 feet to 6 feet but many owners opt to place a roof storage utility accessory which can add at least up to 2 feet in height.
- Sports and compact cars — Smaller than sedans measuring about 5 feet to 6 feet wide and 14 feet to 16 feet long. Height is usually about 5 feet with some luxury sports car measuring just 4 feet or lower. These cars have no problems with small garage door sizes.
- Boats — This covers only the water sport or inshore fishing type boats that can be transported on land via trailer. Typical width is between 8 feet to 10 feet and a length between 25 feet to 30 feet. Anything bigger might be hard to transport and usually remain water bound in a yard. These boats have a height 10 feet to 12 feet but a trailer is used, an additional 2 feet should be considered.
- RVs and mobile homes — Sizes vary per manufacturer but standard models are around 30 feet to 35 feet long, about 9 feet wide and 12 feet to 13 feet tall. These types of vehicles would need large garage door sizes comparable to commercial ones.
Number of vehicles
Aside from the space occupied by each vehicle, there should be at least 2 feet of space in between each vehicle when parked side by side. This is to accommodate car door openings when going in or out of the automobile.
Most owners will take advantage of the additional garage space to store garden tools, lawnmowers, and even golf cars. Some owners even have work tables for personal activities. The garage door should be wide enough to allow activities or moving in and out of items without moving your vehicle.
If you bought a house with a garage, then you would be limited to the size of the garage entrance. Take note of the space required for garage motors and overhead door compartment. For new garages, it’s better to involve an expert or your architect during planning to consider all your requirements.
Use these factors to estimate your current requirement and if you have plans for additional vehicle purchases, better to factor those in before purchasing your garage door.
Standard Garage Door Sizes
Evaluate your current and future requirements to properly gauge the size of your garage door. Below are typical garage door sizes based factors such as function, the number and type of vehicles to the house. These are standard for overhead and roll up garage door sizes and should be readily available for purchase from any garage door supplier.
Single Car Garage Door Size
For homeowners with just one automobile, a single garage door should cover their requirements. Single common garage door sizes range between 8 feet to 10 feet wide and between 7 feet to 8 feet in height. Standard “off the shelf” doors are available in 8 feet x 7 feet, 9 feet x 7 feet, and 10 feet x 7 feet with a taller 8-foot variety available. Single garage door sizes should be wide enough to accommodate any car type and still have enough space for storage.
Homeowners with 2 vehicles can opt to build a garage with 2 bays or garage openings and have 2 standard single garage door sizes installed.
Double Car Garage Door Size
A double car garage door is one door unit that is big enough to accommodate 2 cars. Some homeowners with just one vehicle opt to install double doors so they can have space for cabinets, garden tools, and workshed. Double garage door sizes are usually 12 feet to 18 feet in width and 7 feet to 8 feet in height.
Triple Car Garage Door Size
This monster-size garage door can comfortably fit 3 vehicles and can be an economical as well as an aesthetically better option instead of installing 3 separate single garage doors. Although the downside is you expose all the parked vehicles whenever you open the garage door. The standard size of a triple car garage door is 36 feet to 40 feet wide and 8 feet in height.
RV Size Garage Door Size
RV and mobile home have a considerable height difference compared to cars and vans with most models measuring up to 13 feet high. Standard RV garage door sizes range from 12 feet to 14 feet wide and 14 feet to 16 feet high.
The width of RVs and mobile homes also makes it necessary to have a wider area for better maneuverability.
Commercial Size Garage Door Size
Commercial size garage doors are made to accommodate large containers and trucks. The standard commercial garage door size is 32 feet wide and 24 feet high. Check if this is enough for your vehicles or for the items to be stored. Due to the commercial-grade construction, these doors are thicker and more robust than residential garage doors.
Boat Size Garage Door Size
Garage for small boats is usually customized as they differ in size depending on the type and model. As such, these will have higher openings compared to car garages and may be comparable in dimensions to a commercial size garage door.
Overhead Door Size Limitations
Although you can have any size of garage door below are limitations that can affect or restrict the design of your garage door. This can be either monetary, design limitations, or regulatory.
Higher Cost of Customization
Garage doors are available in many sizes but in case your requirement does not fit these ready-made models, then customization is your only option. Unfortunately, custom garage door sizes require a higher cost due to measurements, custom cutting, bigger garage door rollers sizes, and installation. This is normally encountered by homeowners adding a new garage or upgrading an open garage.
Door & Access Systems Manufacturers Association (DASMA) Regulations
DASMA is a trade association for North American garage door manufacturers. DASMA members represent 95% of the garage door industry making them premier regulatory group for this niche. Their publication regarding overhead door specifications have entries that identify standards for garage door standard sizes, wind loads, durability, hoist operation, torsion springs, and counterbalance.
U.S. Consumer Product Safety Commission
The commission has various regulations that cover residential garage owners and garage door operators (GDO). The aim is to protect the general public from harm if they own or are near garage doors. One such regulation focuses on safety measures to deter accidental entrapment. Another one focuses on regulating overhead’s garage door opening and closing speed. These and other regulations will have a direct effect on residential garage door sizes.
Current Size of Garage
Quite simply, the size of your new garage door should not exceed your current garage door allocation. An expert can help identify the maximum door size that can fit your existing garage. Otherwise, major reconstruction is needed to extend the garage wall and create more space.
What Size Should My Garage Door Be?
It’s almost inconceivable for homeowners not to have a garage or at least a carport. There’s a certain feeling of security in having your car safe and stowed away in a garage protected from harm. A garage can also increase the value of your property as well as create a new space for your hobbies or side projects.
If you are considering a new garage door, the pointers discussed here should be a valuable tool for you to identify the size of your garage door. Do note that it is often better to be overestimating than underestimating the garage door size as it is easier to live with an oversized door than an inadequate one. It is also far easier to reduce a garage than to enlarge to create more room.
But you should also be reasonable when adding for any future requirement as you might end up not using the room space. A recent study showed that 25% of Americans who installed standard two-car garage door sizes don’t actually park 2 cars with most just parking one car. The extra space just becomes storage space and filled with clutter.
