Bay window blinds measuring guides

When you measure a bay window for blinds, you will need to take into consideration the depth of the headrail of the blind as well as anything that protrudes from the window such as large window handles or air vents.

Once you have decided on the type of blind you wish to fit into the bay, then check on the chart below and make a note of the size of the headrail depth.

How to Measure a Square Bay Window for Blinds

Square bay windows are much easier to measure as you will only need to measure the straight sides of the bay.

When ordering blinds for a square or splay bay window, they must be ordered as RECESS blinds.

1). Measure out from the window the largest obstruction, then add on the measurement of headrail depth as shown on the coloured HEADRAIL CHART above. Mark the wall or ceiling with this measurement out from Window B. This will give you the fitting position for the blind.

2). Now measure A from where you want your blind to start in the bay to the mark showing the depth the blind will need to be fitted from the wall and make a note.

3). Measure window B and C as shown above, again having marked the wall with the fitting position of the blind before you measure.

How to Create Your Cardboard Cut-out

1). First measure the largest of any of the window handles, air vents or other obstructions that the blind will need to clear when it is fitted into the bay and make this measurement A.

2). Refer to the coloured HEAD RAIL CHART and make a note of the depth of the headrail of the particular blind you have chosen and make this measurement B.

So for example, if you need to allow 3 cms for a particular window handle A. and you have chosen to fit a roller blind that has a headrail depth of 4.8cms B. then the total length of your template will be

A = 3cms + B = 4.8cms which gives a total length of card of 7.8cms.

You will need 2 of these cut-outs

 


Positioning Your Cardboard Cut-outs

1). Place the cut-outs in one of the angles of the window with the front tips touching.

2). Mark the point where the tips touch with a pencil.

3). Repeat this step in every angle of the bay.

4). These marks are the position you measure for the size of your bay window blind.

5). When you order your blinds, it is important that you order EXACT blinds.
