Step 1

The first step for taking storm door measurements is to measure the height of the door.

You need to place your measuring tape in the center of the door.

Go from the door sill itself at the bottom, all the way up to the trim at the top of the door. 

Step 2

Next, you will need to measure the width of the door.

You are going to take this measurement in two separate places.

The first place is at the top of the door. The second is towards the bottom. 

For each of these measurements, start by measuring from the trim on the left side of the door and go all the way to the right side of the door.

If there are different depths for the trim on your doorway, be sure to measure from the outside trim. 

Step 3

Finally, you need to measure how deep the exterior trim is on the side and the height of the exterior trim at the top of the door frame.

Depending on the storm door replacement you choose you might need to know the door handle clearance.

After this, take three measurements of the width of the newly exposed door frame. First, across 3 times from the top, middle, and bottom of door.

Measure to the newly exposed door frame.

Step 3

Finally, take 2 vertical measurements for the height, starting from the left side to the right side.

Make a note of the smallest size.

Step 4

Now measure the thickness. Open the door and measure the thickness.

If you want to replace the door + the frame, measure with the frame.

Now you have the width, height, and thickness to replace your prehung door!


How to Measure a Door For Replacement Tips

  • Watch for the door swing. Find out if your door has left or right-handed swing to determine if it opens inward or outward. To figure this out, open the door and turn your back to the door hinges. If your door opens on your right, the swing is right-handed and vise versa.
  • Climate can change your door measurements! The frame and door can contract and expand. Warm weather causes expansion, whereas cold weather causes contraction.

I feel SO fortunate to have discovered Green T Services and learn the variety of services they provide. Recently, Brian G. (who turned out to be much more than a handyman), successfully completed a couple projects at my home. Brian's knowledge, efficiency, and professionalism, in addition to his friendliness and patience with me watching him and asking lots of questions was fantastic. Even with his attention to detail, he completed the work in the estimated amount of time and cost. I am now making a list of other needed work I will certainly call Green T for assistance. Thanks Brian!

Brian performed handyman services for my apartment. He hung up tons of pictures and paintings with lightning speed. His work was immaculate. I was so impressed by his level of professionalism and quality of work. I am so happy I hired Green T Services for this job. Brian did a much better job than I ever could have, and my apartment looks fantastic now. I will be recommending Green T Services to all of my friends and family for every one of their home improvement service needs.

Justin cleaned all our vents, and also cleaned our carpets. He was professional, friendly, and very informative. He told us exactly what he was going to do and how it was going to work, before beginning any work, and afterwards, he was good at telling us what had been better or worse than expected. We very much appreciated the information. He managed our expectations appropriately, letting us know which stains he probably would NOT be able to remove (for example, ones that had been there long enough to set). We would definitely use the company again, and hope to have Justin back if the work was suited to him!

I had Daniel Liscano as my technician today and his service was SUPERB! He was professional, nice, courteous, and went above and beyond to ensure I was a happy customer. I had three different services completed in my house and Daniel did not cut any corners on any of them. He was here all day from 9-5 and he worked very hard alone to clean, sanitize, deodorize, and disinfect my house. From the air duct cleaning, hardwood floor cleaning, and carpet cleaning, Daniel completed an EXCELLENT job! This is something I had been wanting to do for a long time and finally took the time to schedule the appointment and I am really happy I did! I can breath better and my allergies are not bothering me as much already! Thank you Daniel and thank you Green T for delivering on your promise of service and professionalism! It was worth every penny! I will be ordering more services soon!
