How to Measure a Garage Door

When it comes to home improvement, a new garage door can enhance your property’s curb appeal, improve security, and even boost energy efficiency. However, before you can explore the vast array of styles, materials, and technologies, the first step is to measure your existing garage door.

How To Measure a Garage Door

Proper measurements ensure your new door fits perfectly, operates smoothly, and meets your home’s needs and aesthetics. So, wondering how to measure a garage door accurately? Follow the steps below.

Step 1: Measure the Garage Door Width

Start with the width of the door opening at its widest point. This measurement is crucial as it determines the door size you must purchase.

Step 2: Measure the Garage Door Height

Next, measure the door opening’s height from the highest point of the floor to the top of the door opening. This step guarantees the door will fit in the opening without any issues.

Step 3: Measure the Garage Headroom

The headroom is the space between the top of the door opening and the ceiling. Measure this space to guarantee enough room for the door assembly and the operating mechanism, including springs and openers.

Step 4: Measure the Garage Side Room

Measure the width of the areas beside the door openings on both sides. This area is for the installation of the vertical track.

Step 5: Measure the Depth of the Garage

Finally, measure the backroom or the distance from the garage door opening to the garage’s back wall. This measurement determines the space available for the door to retract or roll up without obstruction.

Tips for Accurate Measurements

Measuring is a simple task, but even the slightest error can lead to issues with your new garage door’s installation and functionality. Here are some tips to keep in mind:

  • Use a Metal Tape Measure: For precision, always opt for a metal tape measure over cloth or plastic ones, as these can stretch or bend.
  • Measure Twice: Before recording, measure each dimension at least twice. This tip helps detect any mistakes early and ensures the reliability of your measurements.
  • Note in Feet and Inches: Record your measurements carefully in feet and inches, the standard format for door sizes, to prevent any confusion when ordering your garage door.
  • Get Help for Wide Doors: If the garage door is particularly wide, have someone help you hold the tape measure. The tape must stay level and straight.
  • Mark the Measurements: Use a pencil and mark the measured points on the door frame. These visual cues can be a handy reference during the actual installation.

I’ve had excellent service from Doors of Pontiac, from installation of a new door and opener to a fix of the wall unit that disconnected when we removed toe cover to paint. Highly recommend this company.

Amazing company! Doors of Pontiac installed our garage door over 20 years ago and did a great job.All was well until I did something stupid and broke it. I was very worried about possibly needing a new door or something else very expensive. Then Devon arrived and saved the day. He was able to repair the door and do it affordably. He was kind, professional and did great work! My appointment on the phone was made by another kind professional! Couldn’t be happier!! Thank you Doors of Pontiac!!

Harold Junek came out to fix our garage door last week after a cable snapped. Harold was prompt and even sent a text message that he was on his way. He fixed the broken cable, replaced all the wheels and greased up all the joints. Our garage door was up and running in a short time and works great. It's also more quiet. Thanks Harold and Doors of Pontiac. Definitely will be a repeat customer!

Our garage door wouldn’t open, either with the motor or manually. We were stuck with a car inside! I called Doors of Pontiac at 7:35am, not expecting anyone to answer so early. Not only was my phone call answered promptly, but it was arranged that a tech would be at my home the same day between 10am and noon. Technician, Harold, arrived at my home before 10am and was completed with his work in about an hour. He was friendly, helpful, and professional, and solved our problem quickly so that we could go about our day with an operational garage door. Thank you to Doors of Pontiac and Harold! We’ve been customers in the past, and you’ll be our first call in the future.

Joe and an apprentice (Billy?) installed our new front door w/ sidelites yesterday. They removed and reinstalled an existing storm door as well. They were both polite, professional, efficient and did an excellent job. I was very impressed.Side note, Joe was very calm and understanding and a great teacher to his apprentice. As a sports coach to young kids, just listening to the way he explained everything was impressive. Not that Billy didn't understand, but having someone explain the reason for doing something so they actually learn the why is a great asset.
