How to Measure Windows for Replacement in Pasadena MD

Measuring for replacement windows looks simple until you are standing at a ladder, tape measure in hand, trying to figure out why three openings that appear identical are not actually the same.

Start With The Right Opening

Use a metal tape measure, not a soft sewing tape, and record every dimension to the nearest 1/8 inch.

Take width measurements at Pasadena Window Replacement the top, center, and bottom of the opening. Those differences matter because a window that fits the largest measurement may not fit the tightest point.

Look Beyond Width And Height

Width and height are only part of the picture.

If the existing frame is shallow, some products may not sit correctly without extra work.

To see whether the opening is square, measure diagonally from one corner to the opposite corner in both directions.
