Window and Blind Measurement Sheet

One page, top to bottom:

Printed under the title: Every opening in the house measured properly — three widths, three drops, recess or face fit — written down once and used for every quote.

Measure and record; let the supplier deduct. No allowances, deductions or fitting tolerances are printed here. Every supplier specifies their own, and applying somebody else's is how blinds arrive too narrow. Give suppliers your measured sizes and let them apply their deductions.

How to use this sheet

1. Measure in millimetres. Feet and inches are where mistakes hide.
2. Measure each opening three times — top, middle and bottom for width, left, centre and right for the drop — and write all three down. Openings are rarely square.
3. Record the smallest of the three for a recess fit, and say which one you gave the supplier.
4. Say whether it is a recess or face fit, and note handles, tiles, pipes and anything that fouls.
