Blind Measuring Guide: An Accurate Measurement is the First Step to a Perfect Shutter

All blinds and curtains are made to meet your precise requirements, meaning, there is no need to cut down ready-made products on your own so they fit a certain window. Knowing how to measure the space that you want to cover means you can go straight to buying the blinds or ordering the product according to the needed dimensions. Measuring blinds can be a daunting process, but with this blind measuring guide, the process will be simplified and much more straightforward. When measuring, keep the following things in mind:

  • Measure in millimeters (mm);
  • Use a steel tape for improved accuracy – ensure the tape measure is tight and straight when measuring;
  • Measure all windows, those of similar height and width as well;
  • The stacking height of your blind is something you shouldn’t forget;
  • Do not deduct.

Depending on what type of blinds you want, there are different approaches to measuring, but all of them are generally very similar. The two ways a blind can be mounted is inside and out. Regardless of the way they are mounted, you need to measure the blinds accurately in height and width. There are also multiple types of blinds which can make a difference as to how you measure them. Take a look at this blind measuring guide for the most commonly used blind types.

Roman Blinds

Measuring is done at three spots: at the bottom, the top and the middle, the smallest measurement is the one you should take. Measure from the top of the window frame to the bottom in three places: the right side, left side and the middle – take the measurement that is smallest. This goes if you’re mounting it on the inside.
For outside mounting, measuring the width from frame to frame and add around 50 mm to either side for an improved privacy and light control. Then, measure top to bottom and again, add around 50 mm extra should the window be elevated. These blinds are generally better suited for outside mounting.

Venetian Blinds

Same rule applies, depending whether you want them to be mounted on the inside or on the outside the window recess. If you want them inside, you need to measure 3 widths. Using a steel rule, measure across the top, middle and bottom of the window. The narrowest is what is called “the recess width”. Do the same for the drop of the blind. The shortest is called “the recess drop”. For outside mounting, measure again and add around 50 mm to either side to increase light control.

Sunscreen Roller Blinds And Holland Blinds

If your sunscreen roller or Holland blinds are to be mounted inside, measure the hard width at the top and the hard drop from the top to the bottom. Ensure there is a minimum of 60 millimeters’ depth for flush inside mounting. If it is an outside mount, measure the width from the architrave to the architrave at the top of the window frame and the measure from the top all the way to the bottom of the frame.

This pretty much sums it all up, just stick by the golden rule “Measure twice, cut once” and you should have no issues when taking measurements for the next blinds you purchase!
