Blind Measuring Guidelines

Roman Blind – Measuring

Inside reveal

BlindmeasuringinsiderevealWidth – Distance from inside of left side of frame to inside of right side of frame less 1cm.

Length – Inside top of window frame to top of sill less 5mm.

Note:
Measure at three points in both directions and always use the smallest of the three measurements.

Always use a metal tape measure as fiberglass and fabric measures can stretch.

 

 


Outside reveal

Width – Width of sill or width of window plus 5cm either side.

Length – Top of batten (usually 10cm above window reveal) or blind rail to bottom of sill.

Note:
Measure at three points in both directions and always use the smallest of the three measurements.

Always use a metal tape measure as fiberglass and fabric measures can stretch.

 

 

 

 

Blind – Calculating Fabric Quantities

  • First calculate the cut length and widths by adding 10cm to the final width measurements and 10cm to the final length measurements.
  • For plain fabric, divide your cut width by the width of your fabric. Round this up to the nearest whole number to work out how many fabric widths are required. Multiply the no. of widths by cut length to get the total fabric quantity.
  • For patterned fabric, divide the cut length measurement by the vertical pattern repeat and round this figure up to the nearest whole number.
  • Multiply this by the pattern repeat to get the adjusted cut length. Multiply the adjusted cut length by the no. of widths required for the total amount of fabric.
