Measure Blinds

We have guides for measuring individual blinds and blinds within different types of bay window, click an image below for more details.

Measure Individual Blinds

Recess-Window-Fit.pngMeasuring for blinds which fit inside the recess:

Recess Size:
Height: From the top of the recess to the window sill. (Measure in at least 2 places and use to the smallest measurement)
Width: From on side of the internal recess to the other. (Measure in at least 2 places and use to smallest measurement)

Take your Width (A) and Drop (B) measurements from within the window recess. Take care to make note of any obstructions which may affect the width or drop of the blinds. For example it is common place for a bathroom or kitchen window to be tiled from the window sill about half way up the recess. In cases such as this measurement should be taken from the narrowest point E.G between the tiles. Check the recess is square by measuring the width and drop at different points. Use the smallest measurement for your order. Once you have established the recess size, enter these dimensions directly into the website calculator. We manufacture your blinds to fit perfectly into the recess.


Measuring for blinds which fit outside the recess:

Blind size orders are treated as follows...

Your blinds will be manufactured to your exact requirements. Blinds sizes are normally used where a blind is to be mounted outside the recess. As a general rule you should measure the window opening and then add the desired extra width to that size. Take care to allow a generous overlap to prevent anyone being able to see in from outside.
Please take care to allow for any obstructions e.g. wall mounted light fittings etc.
Please note the manufacturing tolerance note on the terms and conditions page (link).

Measure Blinds For An Angled Bay Window

Step 1:
You will need:
- 2 Pieces of A4 or A5 sized paper or card.
- A pencil or pen.
- A tape measure.
- A ruler.

The head rail for our Roman Blinds protrudes by 50mm. if you have window handles or vents that stick out from the window frame, measure how far these protrude and add this to the head rail depth. This will be used as measurement (A)

Step 2:
Using two pieces of paper, place them edge to edge and mark both of them at the required measurement (A).

Step 3
Slide the two pieces of paper towards each other along the window sill of the bay until the two marks that you made meet up.Using a pencil, make a mark on the window sill at the point where the paper meets the window frame.
Step 4:
Measure from one mark to the next as detailed in the diagram. This will establish the width of the blind that you will need to order.
Step 5:
Measure the drop from where the top of the blind will sit down to where you want the blind to end (typically the window sill). All of the blinds should then be ordered as ‘Exact Fitting’.

Measure Blinds For A Square Bay Window

Our roman blind headrails protrude by 43mm from the face of your window frame.
Front blind: Measure along line A (this will be the front blind) in three places and take the smallest measurement. Look out for things which may interfere with your blinds installation such as vents or window handles. Deduct 86mm from this size and make a note of it. Now measure the drop, this would be taken from the top of the window frame or a flat surface above the window which would be suitable for fixing your roman blinds to. If you have handles or vents which protrude more than 40mm you can fix your blinds o the ceiling, we s

Side Blinds: Measure from the face of the window frame (B and C) to the outside edge of the blind, this may be the outer edge of your window frame, or constrained by a wall or reveal. Deduct 43mm (depth of the front blind and any adjustment for window handles along the front. Example, distance B is 500mm, less 43mm (front blind) less 45mm for window handles or vents along the front equals 500 - 43 - 45 = 412mm. This would be then ordered as recess size. Do the same for both sides B and C.
Drop. Measure the drop from your chosen fixing point at different intervals around the whole bay window. Take the smallest drop and enter that as the drop for all your blinds. If you have a significant difference from one side to the other you can order your blinds to suit the differing drops. We will manufacture your blinds so the pattern matches along the top, blinds we differing drops will not match at the bottom, hence of the variation is small it is better to order them all the same drop.

If you require more help, e-mail us some pictures of your bay window, we can mark on the photographs exactly where to take measurements from.
