General 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. Please be a wear the manufacturing tolerance for all blinds is + or - 5mm. The exception to this is our range of blinds for Velux® 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 millimeters (mm) for the greatest accuracy.

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.

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 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 50mm or 2 inches each side and the top to avoid gaps.
• 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. As a guide the cloth will be up to 35mm less than the exact width depending on the end mechanism.

Exact Blind Drop

• Decide how much you wish to overlap the recess at the top & bottom. We recommend at least 50mm or 2 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.

Measuring For Bay Windows

1. Determine the depth of the blinds you are mounting and use this for the width of your cardboard:
25mm metal venetian = 25mm wide.
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 centre 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 ¾cm (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 actually mounts. 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 width measurement if the recess or frame varies from top to bottom. Deduct the following from the width depending on the type of blind you are going to order as follows -

25/35mm wood venetian blind deduct 52mm.

50mm wood venetian blind deduct 70mm.

25mm metal venetian blind deduct 30mm.

Then select option "Recess size".

Example your measured width for the side blind is 680mm, the choice of blind slat is 25mm wood venetian blind, 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.

25mm metal venetian blind deduct 30mm twice.

Then select option "Recess size".

Example your measured width for the side blind is 1680mm, the choice of blind slat is 25mm wood venetian, 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 blind guide below.

25/35mm wood venetian blind deduct 52mm twice.

50mm wood venetian blind deduct 70mm twice.

25mm metal venetian blind deduct 30mm twice.

Then select option "Recess size".

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 blind guide below. Repeat this for the other side blind.

25/35mm wood venetian blind deduct 52mm.

50mm wood venetian blind deduct 70mm.

CURTAIN MEASURING GUIDE

Curtain Width Measurement

Measure the actual curtain track or pole length and not the window. If a new pole or track is being fitted then allow 200mm (20cm) either side of the window for the track to allow the curtains to stack correctly and if possible 100mm (10cm) to 150mm (15cm) above the window reveal. For the correct measuring of different types of fittings see diagrams below.

• DIA 1 For a track that has an overlap measure between points A and
points B and add the two together for the correct curtain width.

• DIA 2 This is a straight curtain track so measure from end to end for the
correct curtain width.

• DIA 3 On a curtain pole, measure between the two finials to obtain the correct
curtain width.



Curtain Drop Measurement

The curtain drop is the finished length, which can be to the sill, below the sill or too the floor. Use the diagram below as a guide, we advise to measure at least three separate points across the track or pole and take the shortest measurement as floors and sills may not be level, this will prevent the curtain from dragging on the sill or floor.

Measurement A is to the sill we advise the curtain to end 1cm above the sill.
Measurement B is to below the sill, we advise 150mm (15cm) below or 20mm (2cm) above a radiator.
Measurement C is to the floor, we advise to end the curtain 10mm (1cm) above the floor.



Track

For pencil pleat/pinch pleat curtains measure from the top of the track to where the curtain will finish.

Curtain Pole

For eyelet curtains measure from the top of the pole to where you want the curtains to finish at the bottom. The curtains are made with 30mm (3cm) of fabric above the top underside of the eyelet ring.

For pencil pleat/pinch pleat curtains measure from the underside of the decorative ring to where you want the curtain to finish at the bottom.
