How to Measure Your Windows and Doors for Replacement

All you need to start the process of getting a quote for your window and door replacement process is a tape measure, a helper and our handy tracking form.


Do you need a prybar to open your windows? Is your door threshold wobbly and rotten? Does the wind blow your curtains around even when your windows are closed? If you can relate to any of these scenarios, it may be time for new windows and doors.


In the past, buying new windows and doors meant you might have set up meetings with a few different sales reps and invite them into your home to measure and discuss design options and pricing. These days, though, a digital meeting might be a better option to discuss the window replacement process. But where does this leave you when you still need to know the measurements of your windows and doors to get a realistic quote? You can do your own measuring, and it’s really quite simple. Here’s how:


Enlist a helper

Measuring windows and doors can be a one-person job, but it will go a lot faster with a helper. Have your helper record the measurements as you go in this convenient printable form. To avoid a mistake, after you read the measurements, have them read the numbers back as you double check the dimensions. It’s also handy to have a helper hold one side of the tape measure when measuring larger windows and doors.


Measure the width

From the inside of your home, use a tape measure, and measure the distance from the inner edge of one side jamb to the other. The side jamb is the vertical piece of trim on each side of the window or door. If your window is finished with drywall instead of jambs, simply measure the distance between the drywall on each side. Round up to the nearest inch and record your measurement.


Measure the height

Measure the distance between the sill of the window and the head jamb. The sill is the lowest horizontal piece of trim. On a door, measure the distance between the threshold and the head jamb. If your window is finished with drywall at the top instead of a head jamb, simply measure up to the drywall. Round up to the nearest inch and record your measurement.


Don’t worry

What if your measurements are not perfect? Don’t worry, if you do decide to choose Marvin for your home improvement project, a friendly and knowledgeable window and door expert will confirm all measurements before ordering your new Marvin windows and doors.
