How to Measure Windows for Replacement in Powell TN

Start With The Right Kind Of Measurement

The tape measure is the easy part. The hard part is measuring the correct points, because a window opening can look square even when it is not.

The Three Measurements That Matter Most

Height Measurements

Measure from the highest point of the sill area to the top of the opening, not to the molding unless the manufacturer specifically asks for a trim-to-trim measurement.

If the bottom edge is soft, rotted, or out of level, note that for the installer.

Depth And Frame Space

Measure from the interior stop to the exterior stop, or from the inside face of the frame to the outside face, depending on the window type and the manufacturer’s instructions.

A good installer will check this before ordering, but you can screen out obvious mismatches early by measuring carefully.

Where DIY Measurements Usually Go Wrong
