Decorama Blinds are manufactured to the measurements you provide. Have on hand a steel measuring tape, paper and pencil, and a step ladder for high measurements. Please follow these guidelines carefully.

Precision Measuring

• Decide if your blinds will be inside or outside the window frame.
• Always use a steel tape measure for accuracy. DO NOT use a cloth tape.
• Measure and round off to the nearest mm. Check in several places in case the window is not perfectly square.
• If deductions are necessary, the factory will make the allowances. Do not make these yourself.
• First, measure WIDTH, write it down. Clearly indicate this measurement is the width.
• Second, measure DROP, write it down. Clearly indicate this measurement is the length.
• It is very common to transpose measurements. Always indicate the WIDTH measurement first, then the HEIGHT last. (e.g.. 2150w x 1530d or 2150 x 1530)
• Remember one very important thing when measuring for an inside mount - Take the ACTUAL WINDOW OPENING SIZE to give to us, our factory will take all the proper allowances for it to fit into that opening.
• Double check ALL measurements.

• WIDTH: Measure the EXACT width of the window in three places. Use the narrowest width measurement.
• DROP: Measure the EXACT DROP of the window in three places. Use the shortest height measurement.
• Window Depth: The space from the windows outer edge to the back of the window (or obstructions such as handles).

• Specify the EXACT WIDTH and EXACT DROP you want the end product to be. Your product will be made exactly as you specify with no deductions.
• The normal width is measured to the full extent of the architrave.
• If you have no architraves - to minimize light gaps and obtain maximum privacy, add 100mm on each side. If you wish add extra length to the drop if blind not to the floor.
