Ans: Begin by measuring the opening size and dividing it by two to get an approximate width for each door. If the frame has not already been fitted, you must account for this (the most typical frame width is 30mm on both sides) as well as some fitting tolerance (about 2-3mm per side).To calculate the width of a single door, divide the opening width by the frame width (e.g., 60mm) and the fitting adjustment (6mm).
Compare the Single door width to the sizes available in your selected design to see if a standard choice would suffice or if you need bespoke made-to-measure doors.
