How to Measure for Replacement Windows + Patio Doors
If you’re considering replacement windows or a new patio door, you can easily measure your windows and doors to have handy as you begin shopping. Find out where you should measure so you get an accurate picture of your window and door dimensions.
How to Measure Windows
Window and door measurements are always recorded width first and then height.
1. Measure Window Width
For windows, measure the inside of one jamb to the other with a tape measure. The jamb is the vertical piece of trim on each side of a window. If your window doesn’t have a jamb, measure from each end of drywall. Record the measurement.
2. Measure Window Height
For windows, measure from the sill, the horizontal piece forming the bottom of the frame, to the head jamb, the horizontal piece forming the top of the frame, with a tape measure. If your window doesn’t have a head jamb, measure from the sill to the drywall. Write down the measurement.
You don’t need to measure depth because a Marvin Replacement consultant will verify your measurements during your appointment. Window depth is tougher to measure because windows might not rest exactly at 90°.
How to Measure Patio Doors
1. Measure Patio Door Width
For patio doors, measure from the inside of one jamb to the other with a tape measure from inside your home. Record the measurement.
2. Measure Patio Door Height
For patio doors, measure from the threshold, the lower, horizontal piece on the interior of the door that supports the frame, to the head jamb, the horizontal piece forming the top of the frame, with a tape measure from inside your home.
What to Do with Measurements
Once you’ve recorded your measurements, schedule an appointment with a Marvin Replacement expert to discuss options in a no-pressure, hassle-free in-person or virtual consultation.
When you move forward with your project, a measure technician will verify all window and door measurements before placing your order. If you’ve got Special Shape windows, we can help measure those for you.
