How to Measure Windows for Replacement in Florida Homes

Begin With A Reliable Measuring Method

Measuring for replacement windows is not just about grabbing a tape and writing down a width and height.

The goal is to size the new unit to the rough opening and the existing frame conditions, not to the visible glass alone.

Before you measure, open each window and check whether the frame is square, warped, rotted, or soft at the sill.

Use a steel tape measure, not a cloth tape, and record every number to the nearest 1/8 inch.

How To Measure Width, Height, And Depth

For a standard replacement, measure width at the top, middle, and bottom of the opening.

In Florida homes, settling, moisture movement, and past repairs often leave the frame slightly out of square.

If the frame shows rot, previous patching, or uneven reveals, let a professional handle the final numbers.
