If you are looking to replace a garage door or building a new garage, you’ll find plenty of options available. You can choose from different styles, features, and colors, but the most important concern should be your garage door’s size. In this guide, we will look at all the different options of garage door sizes available to you; by the time you have finished reading, you’ll understand common garage door dimensions and what to consider when choosing the right size for your needs. 

While replacing a new garage door isn’t a once-in-a-lifetime task, you can expect it to last around twenty years before a new one is required; therefore, you should consider your present and future needs before any upgrade. 

The majority of homes have garages built for single or double car accommodation; two-car or three-car garages are much more common today, as are larger sized doors and openings designed to accommodate more oversized vehicles such as RVs. 

Though garages were initially designed to keep cars out of the elements, today, the vehicles that householders own and garage usage have changed. The variety of vehicles that a garage might contain includes SUVs, pick-up trucks, ATV vehicles, RV’s and even boats. Garages are used as places of storage, for hobbies such as home gyms and workshops, and all sorts of other uses. 

With all these new considerations choosing the right size garage door shouldn’t be rushed. Think about the type, dimensions, and the number of vehicles you want to accommodate and any additional space needed for storage. Ideally, you will want the garage door to be wide enough to allow you to move items such as a lawnmower in and out of the garage without having to move your car every time.


Common Single Garage Door Sizes


The standard height for single garage doors is 7 feet; for older properties, the width was typically 8 feet. Standard measurements for single doors these days are 8 x 7, 9 x 7, and 10 x 7 feet. If you have just one car, such as a sedan, with no plans to store lots of items, then a standard 8 x 7 garage door should be fine. However, if you own an SUV or a large pick-up, you’ll need to opt for a 9 feet wide garage door at the least.


Common Double Garage Door Sizes


If you want to fit a couple of vehicles in your garage comfortably, then you’ll require double doors. The most common dimensions are 16 feet, but they range from 12 x 7 to 20 x 7 feet. This type of garage door is worth considering even if you have one car and want to use the space for other purposes. 

The smaller 12 and 14-foot garage door sizes are sometimes called one and a ½ car garages, offering plenty of space for a single car and extra storage for additional items such as a lawnmower or motorcycle. 


Two Single Garage Doors vs. One Double Garage Door


If you have two cars, you can also choose to either install a double garage door or two single doors. Two single garage doors can be advantageous, and as the cost isn’t much different in price, it’s worth considering. The only extra expense would be that two garage door openers will be required instead of one.

 If aesthetic appeal is important to you, you’ll find that having two doors adds more balance and design appeal. On a more practical basis, as many garages are used as an alternative to your home’s front door and are opened and shut constantly, in cold weather, a single door will let in less cold air, making it more energy-efficient. Another practical note is that if one door malfunctions and can’t open, it will allow you to get your cars out of the garage, while with a double door, they would both be stuck.


Three Car Garage Door


Do you need a triple garage door to fit three cars comfortably in a garage? No problem, the standard dimensions for three-car garage doors are 32 x 8 to 40 x 8 feet though many homeowners prefer to opt for three single or a single and a double garage door.


Garage Door Sizes for an RV 


Recreational vehicles and mobile homes can vary greatly in overall dimensions. Standard motorhomes are typically 8 ½ feet in width, but you will need to take the mirrors on either side of the vehicle into account. They can be anywhere from 10 to 16 in height and 20 to 45 in length. You’ll need to measure your RV and then choose the garage doors to match.


Commercial Garage Door Sizes


Commercial garage doors are typically larger than their residential counterparts and vary depending on the types of vehicles and equipment being used. The standard commercial door size is 24’1″ high x 32’2″ wide. However, with businesses having different requirements, custom doors are often a solution. A commercial enterprise will need to make considerations on garage door dimensions based on the size and number of trucks that they have.


Measuring Garage Door Size


You’ll need to take a few simple measurements to determine the size of your garage door.

The first and most important measurement to take is the width and height of the existing opening. Be aware of any potential issues, such as the floor not being level. Next, measure the left and right side room width; this is the space from the wall to either side of the opening. You’ll then need to measure the internal headroom, the distance between the top of the door opening, and the garage ceiling. Lastly, measure the depth of your garage; the standard measurement is that the depth should be more than one foot longer than the garage door’s height. You should additionally check for any obstructions that could hinder the door track, such as lighting or pipes.


Additional Height for your Garage Door


If you need additional height for your garage door, it doesn’t necessarily require a complete garage door replacement. You can use a high lift conversion kit to extend the existing garage door tracks to gain more clearance. This maximizes space and saves the cost of replacing a garage door. It’s either a task for an experienced DIY enthusiast who understands garage mechanics or by hiring a professional garage door technician to install it.


To wrap it up…

If you are replacing a garage door that is worn or faulty, determining the size and getting a new one installed is a straightforward process. If you are upgrading or building a new garage, you are best to consider any future requirements that might change; might you be upgrading to a bigger vehicle such as an SUV or a pick-up, or are your kids getting closer to the age that you might need space for a third car in the garage. Is that future dream of owning a recreational vehicle to tour the country any closer? Where are you going to store it? Before sizing up your garage door, take some time to reflect on your future needs.
