When measuring door dimensions we will measure the width and height of the screen itself and add a border to allow for attachment directly to the door utilizing our Hardware fastener to attach. Our standard border is 2 inches but depending on attachment area. The minimum attachment area will be 1” for fixed panels. For example if our screen measures 28” wide by 68” tall we will our 2 inch border and the final build of this door panel will be 32” Wide by 72” tall. We will measure the same way for vent panels above door.
