Measure your existing door height, width and thickness.

Check that the door frame is square by measuring the door frame diagonally. If the frame is out of square, you may have to order a slightly larger door and trim it to size. A trimming allowance of up to 5mm is allowed on most doors.

Keep in mind that approximately 3mm clearance is required for the top and sides of the door and 5mm for the bottom, above the floor covering.
