How to Measure – Garage Door


To replace or update garage doors, proper measurement is crucial. Furthermore, garage door measurements will help you calculate your garage’s clearance level—in other words, you’ll know the maximum-sized vehicle that you can pull into the space. Adequate measurement consists of recording more than simple side-to-side and top-to-bottom dimensions. Luckily, proper measurement is relatively simple and can be achieved by two people in just a few minutes, with just a simple tape measure and step ladder.


    1: Use a tape measure to measure the Garage Door’s opening from side to side near the floor of the garage. Measuring large dimensions of a Garage Door can be very tricky for one person. Ask a friend to help you hold one end of the measuring tape. Record this first measurement and all subsequent measurements on a piece of paper.

    2: Measure the door’s opening from side to side again, this time near the topmost part of the Garage opening. Measuring both top and bottom width-wise dimensions will let you know if the door warped—if you get two differing dimensions at each point, then your door’s opening is slanted or bent, and you should hire a contractor to fix the problem.

    3/4: Stand on a stepladder and measure the Garage Door’s opening from top to bottom. For this measurement, you can take advantage of gravity, letting the tape measure fall to the ground for easy measurement. However, you’ll still want a friend handy to hold the stepladder for safety purposes. With this lengthwise measurement and your previous width-wise measurements, you’ll know how large the opening is for vehicle and door replacement purposes. However, additional measurements are also useful.

    Once you have worked out the area, the gap now needs to be reduced to allow for opening clearances. These are as follows:

    Reduce Width by 30mm (1 1/4″) – allows 10mm per side and also 10mm for centre
    Reduce Height by 35mm (1 1/2″) – allows 10mm at top and 25mm at bottom

    If you are putting in a new frame, please remember to also reduce this off your opening gap. For more info, please call for advice.



    Stunning service from start to finish with text and mail updates on build progress, Then when the gate arrived I was really pleased with the quality of the build. Would buy again.

    This is the second gate we have bought from Gates and Fences. We were very happy with the first although the queue at that time was long, they kept in touch all the way until it was delivered as and when promised.

    We like the quality and finish of the first so felt quite happy to wait for the second and we were delighted when it was promised and also delivered in a much shorter timespan.

    Communication throughout the process was excellent and the care taken to ensure that our order was accurate and contained everything we needed. Well Done!

    Quality product and excellent service. Very pleased with my new side gate which is solidly built and will clearly last many many years. The ordering process was efficient with clear and helpful responses. I’d definitely use this firm for any future needs.

    Easy to use website, well followed up with email progress reports as build progressed. Arrived on promised date, friendly crew unloaded gates.
    Builder confirmed good quality gates and hinges/fittings also look good. Gates have now been installed and we are very pleased with the way they enhance the kerb appeal of our house.

    I received regular updates on progress hence able to plan fitting easily (gate is for busy hotel) The gate was well packaged, everything was present and correct. Build was very good, it’s a decent weight and I think it’ll prove solid enough to cope with the use it’ll get for many years.
    Visually it’s excellent and has already drawn several admiring comments.
    Overall a super service and quality product.

    A properly made gate built to last.
    The whole experience was excellent, I was helped measuring the opening, discussing the options and finally choosing the right gate. I was kept informed during the UK manufacturing process, order was shipped as arranged, all well packaged. Hanging the gate (on my own) was possible, the instructions could be a little clearer but help is at hand via telephone. After sale service is also first rate. Overall – Very impressed 5 *****

    From my first phone call to delivery, the information, advice and general communication was excellent. I was firstly advised that there might be a 4-6 week lead-in time but the gates were delivered in 4 weeks from ordering. That is 1st class service. E-mails kept me informed of the start of the manufacturing, to the end of the process of staining, oiling, quality control to delivery date. Well done.

    An excellent product at a reasonable price. Right from my first enquiry the company was very professional. They helped confirm my calculations for a bespoke size and kept me informed every step of the way. Quoted 5 weeks the our gate arrived in just 3. Product was of good quality and arrived well protected against damage. I found the website very good too. All in all very pleased with our purchase. Andy Boulter

    I ordered a side gate from Gates and Fences as they were one of the few companies that could offer a bespoke gate at a reasonable price. I was very pleased with the quality of the end product, and it arrived well within the advertised turn-around time.

    Cheryl Robertson


    After completing the on-line order information, the company were very quick to respond and clarify my requirements.They did this by email and it a was a very efficient process. I was updated by email throughout the manufacturing process right up to when the side gate I ordered was delivered. Although I have not installed it yet, it looks magnificent ‘a beast of a gate’, but very good looking. I would highly recommend this company.
