Take three door frame to door frame measurements as shown in fig 1 top centre and bottom. If these measurements are the same your door is hung straight in the door frame, deduct 5 millimetres from the width obtained and select option edge banded in the order form. Deduct 10 millimetres from the door frame width for French doors. If you have two or three different widths take the widest measurement and select option edge trim in the order form, this allows you to plane the door to the required width top to bottom.
Take three measurements from the top of the door frame to the floor as shown in fig 2 left side centre and right side, deduct 5 millimetres for clearance this will give you the required height. You can proceed to order your new upvc internal door.
