Window Blinds Measuring Guide
All our blinds can be fitted into the face of your window frame, wall or into the top of the lintel. This gives you complete control over the fitting of your new blind. There are generally two fitting options for your new window blind, recess or exact. The exception to this is our range of blinds for Veluxฎ windows, these are made to fit the window size exactly, we simply require the window code.
Recess This is the measurement you need to take if you want your blind to fit inside the window recess.
Exact This is the measurement you need to take if you want your blind to hang outside the recess overlapping the window.
Handy Hint Always use a steel tape measure and write down your measurements in millimetres (mm) for the greatest accuracy.See The Inches to mm converter
How to measure for a Recess Fitting
Width Measure the inside width of the window recess at the top, middle and bottom. Use the narrowest width measurement.
Drop Measure the height of the window at the left, centre and right. Use the shortest height measurement.
Roller Blinds Measurement Guide
Measuring your windows to decide which size of blind to order is easy. Just follow these simple steps. Please use a metal tape measure to take measurements. .See The Inches to mm converter
Recess Measurement
Used when the blind is to be fitted inside the window recess.
|
Recess Width
Take 3 measurements for the width of the window recess as shown in the picture from wall to wall.
Take the smallest of these measurements. This is the recess width. When measuring look out for things like window handles or tiles and take their position into account this way you will be sure of a perfect fit.
Recess Drop
Take 3 measurements for the drop of the window recess (heads to sill) as shown in the picture.
Take the smallest of these measurements. This is the recess drop.
We will make the necessary deductions of 12mm for the fittings & brackets to ensure the blind operates perfectly within the window recess.

Exact Blind Measurement
Used when the blind is to be fitted outside the window recess.
Exact Blind Width (also known as pin width or finished blind width)
Decide how much you wish to overlap the recess at each side. We recommend at least 75mm or 3 inches each side to avoid gaps of light.
Take the overall width measurement including the overlap. This is the Exact Blind Width.
Note: This width includes the operating mechanism of the blind and is not the width of the cloth. See diagram C below.
Exact Blind Drop
Decide how much you wish to overlap the recess at the top & bottom. We recommend at least 75mm or 3 inches at the top if the blind is required to roll up fully above the window recess.
Take the overall drop measurement including the overlap. This is the Exact Blind Drop.

Cloth Measurement
Used when the width of the cloth on the roller blind is important.
Cloth Width
Measure the width the blind cloth is required to be.
Note: The full width of the blind will be wider than the cloth width. See diagram C below.
Drop
Take the overall drop. This is the same as the Exact Blind Drop.

Measuring For Bay Windows
1. Determine the depth of the blinds you are mounting and use this for the width of your cardboard:
25mm / 35mm wood venetian = 50mm wide.
50mm wood venetian = 70mm wide.
2. Cut two pieces of cardboard (depth determined from 1 above) wide by 30cm (12") long.
Important: If spacer blocks or extension brackets will be used for extra clearance on outside mounts, add the amount of extra clearance to the width dimension of the cardboard before measuring.
3. Place the strips in the left angle first, and bring them together until the front corners of the cardboard meet. Mark points "A" and "B".
4. Repeat this step for the right side angle, marking points "C" and "D".
5. Measure between points "B" and "C" to obtain the width measurement of the center window treatment.
6. Measure from point "A" outward to the desired width to obtain the width measurement of the left window treatment.
7. Measure from point "D" outward to the desired width to obtain the width measurement of the right window treatment.
8. Deduct about พcm (7.5mm) from each of your measurements to allow for clearance.
SQUARE BAY WINDOWS
Type A
Use this method to cover the front window more effectively. The best method if you want to stop direct light from the front or to stop people looking in directly from the front. There may be a small gap where the side blinds meet the front blinds but this is usually obscured by the window frame at the corners.
Taking measurements
Front blind
Measure the width of the recess where the front blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom.
Side blinds
Measure the width of the recess where the first side blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom. Deduct the depth (projection from window) of the blind you are going to order as follows - 25/35mm wood venetian blind deduct 52mm -- 50mm wood venetian blind deduct 70mm, then call it recess size.
Example your measured width for the side blind is 680mm, the choice of blind slat is 25mm, so 680-52=628mm, this is the size you quote as a recess size for the blind to operate correctly. Repeat this for the other side blind.
All Blinds to be ordered as recess sizes.
Type B
Use this method to cover the side windows more effectively. The best method if you want to stop direct light from the sides or to stop people looking in directly from the sides. There may be a small gap where the front blinds meet the side blinds but this is usually obscured by the window frame at the corners.
Taking measurements
Front blind
Measure the width of the recess where the front blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom. Deduct two times the depth (projection from window) of the blind you are going to order as follows - 25/35mm wood venetian blind deduct 52mm twice -- 50mm wood venetian blind deduct 70mm twice, then call it recess size.
Example your measured width for the side blind is 1680mm, the choice of blind slat is 25mm, so 1680-52-52=1576mm, this is the size you quote as a recess size for the blind to operate correctly.
Side blinds
Measure the width of the recess where the first side blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom. Repeat this for the other side blind.
All blinds to be ordered as recess sizes
Type C
Use this method if you do not want the blinds to overlap at the corners or if you require a more symmetrical look. There may be a small gap where the front and side blinds meet but this is usually obscured by the window frame at the corners.
Taking measurements
Front blind
Measure the width of the recess where the front blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom. Deduct two times the depth (projection from window) of the blind you are going to order. See depth of wooden blinds guide.
Side blinds
Measure the width of the recess where the first side blind will go. Make sure you take the smallest measurement if the recess or frame varies from top to bottom. Deduct the depth (projection from window) of the blind you are going to order. See depth of blinds guide. Repeat this for the other side bind.
