Project Overview

measuring garage door size

Homeowners have assorted reasons for replacing the garage door. Some people simply want an updated look that increases the value and curb appeal of their property. Others replace the garage doors because there is damage to the current structure. The reason for replacing the garage door is unimportant. What is important is learning how to measure the garage door size for purchasing a new one. Long ago, garage doors were sold or made in only a couple sizes, so the task of replacing was fairly simple. Things have changed now, however, and today garage doors are constructed in an array of different sizes. The increasing size of vehicles is one of the reasons for a change in the sizes of garage doors.

Now that replacing a garage door is a more difficult task than it was at one time, homeowners must take the time to learn proper measurements to ensure accuracy of the new door they purchase. Garage doors come in standard sizes ranging from 8-feet to 20-feet in width, though it is increasingly difficult to find a new garage with a small width of only 8-foot. Standard garage door height ranges from 7-feet to 8-feet. Some homeowners with older garages have newer model vehicles that do not easily fit inside some of the older garage doors, leaving many to wonder if increasing the garage door size is a solution to the problem. While it might seem that it is as easy as increasing the door size to fix the problem, in most cases, the only solution is rebuilding the garage to a larger size.

Step-By-Step Instructions

1

Measure The Width

Measure Garage Door Sizes

Measuring with your tape at the widest part of the door, measure the door width. The door width is the distance between the left and the right sides of the opening. When measuring, measure from the two jambs on the inside of the garage door opening. Most door jambs are surrounded by a 2x6 wood frame on the inside. Record your measurements on paper.

The problem with increasing the size of the garage door is the header that rests above the garage door opening. This header must be removed or rebuilt, which isn't possible without increasing the height of the roof. That is a big job, and not a simple DIY project. Although increasing the garage door size might be impossible, you can easily replace the door in the same size when the need arises. And while the array of garage door sizes might cause added steps to get the right door size, it isn't impossible. A few simple measurements and you’re ready to replace the door. It’s a fun DIY job any handyman can complete in a matter of a few minutes, and puts you one step closer to garage door replacement.

2

Measure The Height

Use your tape to measure the height of the garage door at the highest point. So, you’ll measure from the bottom of the header to the floor to get an accurate measurement of height. Record these numbers on your paper. Measuring the garage door you’re replacing is the easiest way to get precise measurements for the replacement door. If this door is still available, intact and in good condition, measure the door rather than the garage door frame to save time and hassle. If the door is unavailable or you’d prefer measuring the garage door opening, the step-by-step instructions below will help you accomplish the task.

Using the information below, learning how to measure the garage door size for purchasing a new one is simple. Whether you’re a DIY pro or an eager learner in the handyman game, measuring door sizes is always an easy task you can complete in less than an hour. This step-by-step guide ensures accurate garage door measurements, ensuring simple garage door replacement.

3

Measure The Side & Head Room

garage door length and width

The sideroom is the space on either side of the wall after the garage door opening. A minimum of 3 ¾” space is required on each side for proper vertical track installation.  Again, write the measurements on your paper.

The area between the jamb header (door opening) and the ceiling is known as the headroom.  Measure this area. There should be a 10” space for a standard spring installation system; 12” for . If you’re installing a garage door opener, add an additional 3” to the required headroom requirements. If you guessed that you should write the measurements down on the paper, your assumptions are correct.

4

Finalizing Everything

purchasing a new garage door size

Measuring the garage door is pretty simple if you’ve used a tape in the past, but don't worry if you’ve not. This is one of the easiest tools in the box to learn to use, and simple enough for even a child to operate. When measuring the garage doors, take your time to ensure accuracy. Without accurate measurements, the door isn't going to fit, and you’ll either need to make many adjustments so that it will fit or order an entirely new door, both of which cost money and waste valuable time.

Measuring the backroom is one of the final steps necessary to complete measurements for a replacement garage door. To measure the backroom, measure from the garage opening to the back wall of the garage. An additional 18” is needed, plus the door height. If installing an automatic garage door opener, more than 18” of space may be needed. Write your measurements on the paper. Now that you’ve measured the garage door size, take those measurements to your local home improvement store to choose your new garage door. Prepare to spend a bit of time searching the garage doors available for purchase while there. Sorting through the options is half the fun of replacing a garage door!

Conclusion

When measuring the garage door size, look for any imperfections within the door frame, including jambs that are not in good condition, unlevel flooring, and rotting wood. These malformations can impact the measurements and cause further frustrations. Perhaps repairing them now is a good idea.

Accurate measurements ensure a garage door that properly fits the space. With the above step-by-step instructions, you know how to measure the garage door size for purchasing a new one, making replacement simple.
