How to measure and determine doorway dimensions for choosing or producing door fittings?



Height=H, measure the height on left, middle and right for a mean value, if variation too much then choose the minimum one.

Width=W, measure the width on top, middle and bottom for a mean value, if variation too much then choose the minimum one.

Depth=D, measure the depth on top, middle and bottom for a mean value, if variation too much then choose the minimum one.
