How To Measure Width, Height, And Depth

Width

If the opening looks uneven, that is normal.

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.

If the frame is too shallow, a product that looks perfect on paper may not fit correctly in real life.
