Measuring Instructions: Roller Blinds For Boxed Bay Windows

Option 1: The most common method of installation

1) Measure the full width of the front window. Order as RECESS SIZE

2) Measure the full width of each side window seperately as they are often different and note the sizes down then deduct X from that size.
e.g. Top fix fitting: 870mm wide x 1800mm drop. Side window 870mm - X (53mm) = 817mm

3) Order the two side blinds as BRACKET TO BRACKET SIZE.

Option 2: The most tricky method of installation

On both corners measure from the corner of the bay to the start of the glass, if either measurement is less than 70mm then we recommned to not use this option and use option 1 or option 2.

1) Measure the full width of the front window and deduct TWICE the bracket allowance X.
e.g. Top fix fitting: 2000mm wide x 1800mm drop. Front window 2000mm - X (53mm) - X (53mm) = 1894mm

2) Measure the full width of each side window seperately as they are often different and note the sizes down then deduct X from that size.
e.g. Top fix fitting: 870mm wide x 1800mm drop. Side window 870mm - X (53mm) = 817mm

3) Order ALL THREE blinds as RECESS SIZE.

Option 3: Good if you have very small side windows

1) Measure the full width of the front window and deduct TWICE the bracket allowance Z.
e.g. Top fix fitting: 2000mm wide x 1800mm drop. Front window 2000mm - X (53mm) - X (53mm) = 1894mm

2) Measure the full width of each side window seperately as they are often different and note the sizes down, no deductions are made.

3) Order ALL THREE blinds as RECESS SIZE.

DROP

1) Measure the full drop of the window from where the brackets are mounted to where the fabric should finish.
