Petra Ink Blue Vision Day and Night Blind

Please read the guide below and let us know which type of measurement you are providing:

Recess Size

If you want to fit your blind within the window recess as shown above, please provide us with Recess Size measurements.

To do this you will need to measure inside the window recess from wall to wall for the width and from ceiling to window sill for the drop.

You should take the measurements three times to make sure you get the most accurate sizes - at the top, at the middle and at the bottom for the width and at the top, the middle and the right for the drop.

The three sizes to give us are the smallest of the three measurements for both the width and the drop.

Make sure you do not make any reductions from these sizes yourself. We'll make your blinds slightly smaller on the width than the sizes you give us to make sure that it fits into the space with enough room for it to be installed easily and so the brackets don't scrape the walls, while still covering as much of the window as possible. The adjustment size will differ depending on the type of blind you choose and whether you are adding a cassette to cover the roll - our team will be happy to confirm the reduction amount for you if you advise which blind you are ordering.

Remember that the width of the fabric will always be slightly less than the total width of the blind to allow for the size of the mechanism and brackets - the difference is usually approximately 3.5cm.

Fabric Size or Blind Size

If you want to fit your blind outside of the window recess we recommend overlapping the window by at least 10cm on the width and 10cm on the drop.

You can then specify whether you want us to use these measurements as the Fabric Size or the Blind Size.

Fabric Size

If you choose Fabric Size we will use your measurements as the size of the fabric part of the blind only. This means that the size of the brackets/mechanism/cassette will be in addition to the sizes you provide us - this is usually 3.5cm but our team will be happy to confirm the amount for you before ordering.

Blind Size

If you choose Blind Size we will use your measurements as the size of the total blind including the brackets and mechanism (and cassette if ordered). This means that the fabric part of the blind will be slightly smaller than the sizes you provide. The amount of difference varies depending on the type of blind ordered - it is usually 3.5cm but our team will be happy to confirm the amount for you before ordering.

The control chain/cord for your blind can be on either the left or right side.

When deciding, consider whether you have any furniture that will make reaching the controls harder on a certain side; or if you are having multiple blinds in the same room whether you want them all on the same side or on opposite sides.
