How to measure

How you should measure up your window depends on how you intend to set up your roller blind.

All our roller blind widths are specified as total width, which means the total width of the roller blind including the brackets. Since the wall brackets add about 3.5-4 cm, the fabric on a 100 cm wide roller blind is about 96-96.5 cm wide.

MOUNTING ON WALL

Wall mounting is recommended when you want the fabric to cover the window, such as if you have a blackout roller blind and want to be sure there are no gaps for light to seep in.

For blackout, it is a good idea to choose a size that allows the fabric to extend at least 5 cm onto the wall, to minimize the incoming light.

MOUNTING IN NICHE

For niche mounting, it’s important to use measurements insuring the fit inside the niche. 

Measure the niche at a minimum of 3 places (at the top, in the middle and at te bottom) Use the smallest measurement and deduct an additional 5 mm. Use this measurement when ordering. 

 

Measuring for windows opening inwards

Multifix roller blind

Multifix is installed on the window sash, which should be a maximum of 2 cm thick if the brackets are to fit. If you have a thicker window sash in wood, you can also fit a Multifix roller blind as it even comes with metal brackets that can be nailed into the top of the window sash regardless of thickness.

When measuring to see which roller blind width you should order, you need to consider the window handle so that the fabric will fit inside it. The size you specify refers to the total size of the roller blind, including the wall brackets. So you need to measure the distance between the brackets. The actual fabric is about 3.1 cm narrower than the total size.

Example:
You have a window 100 cm in width, with 90 cm of glazing. Inside of the handle is 2 cm of window frame before the glazing begins, but as we do not want the fabric to catch on the handle, we subtract about 0.2 cm.

So we have 90 cm of glazing + 1.8 cm of window frame inside the handle (with a margin of 0.2 cm). The best looking result is achieved with equal amounts of fabric on both sides, so we say 1.8 cm on the other side as well. This means the fabric width is 93.6 cm. Since the fabric is about 3.1 cm narrower than the total size, the total size is 96.7 cm. This is the size you should specify when ordering!

Fusion roller blind 

Note! Fusion can be mounted in several ways. For wall mounting on niche mounting – follow instruction at the beginning of the page. For mounting on window sash- follow these instructions:

How to measure for tension roller blind

When ordering Hasta Tension, you should always specify the exact width of the window niche so that we make the roller blind in a size that provides a perfect fit. Always measure the niche exactly where the roller blind is to be installed in case the niche is slightly uneven.

If you have a window that is very uneven and asymmetrical, it can be a good idea to check so that it doesn’t differ by more than 1 cm in width on each side of the niche. Otherwise, there’s a risk that the roller blind will hit the side of the niche when rolled down.

Glossary – words and terms

Total size

The total width of the roller blind including the brackets.

Fabric size

The total width of the fabric. This is about 3.5-4 cm narrower than the total size.

Fitted height

The maximum height that you can extend the roller blind. The total height of the roller blind fabric is greater than the fitted height. This is because you should never extend the roller blind all the way out, as there is a risk of it coming loose from the roller. Accordingly, never pull the roller blind beyond the recommended fitted height.

Mounting height

The height at which the roller blind is to be installed. This height must be specified under European legislation in order to ensure that ball chains and cords are out of reach of young children.

Ball chain

The chain you use to adjust the roller blind up and down.

Bottom bar

The rod/bar inside the hem at the bottom of the roller blind to weigh it down so that the fabric hangs straight.

P-bracket

A safety device for the ball chain that is used to attach the ball chain to the wall to keep it out of reach of children.

Under roll

This means that the roller blind is rolled such that the roller is visible and the fabric is close to the window. Recommended and standard for blackout roller blinds.

Over roll

This means that the roller blind is rolled such that the roller is not visible, which means that the fabric is some distance from the wall. Recommended for screening and decorative roller blinds and when you would prefer not to see the roller.
