Measure for your replacement windows according to the manufacturer's instructions. Different windows will need slightly different measurements. In general, you'll be measuring the inside height and width of the old window. Measure each window and make a map of where they're located in the house. Vinyl replacements are custom manufactured to fit each opening.

Make any adjustments needed to the framing to accommodate your new window. Consult the manufacturer's specifications for the correct opening size. The window should fit snugly inside the old opening but may need a wood strip for a spacer on the window jamb if it's a little narrow.
