How to measure for curtains and blinds

Accurate measurements help your curtains or blinds fit the window correctly. Always use a metal tape measure, record every measurement carefully and measure in centimetres unless the product page states otherwise.

Measure the window in centimetres and record width first, followed by drop.

Choose measurement unit

1. Measure the width

Measure the curtain track or pole rather than the window itself.

Measure the complete curtain track from one end to the other.

Curtain track

Measure the full width of the track from one end to the other. Do not measure only the width of the window.

Measure only the usable curtain pole width between the two decorative finials.

Curtain pole

Measure the usable width of the pole between the decorative finials. Do not include the finials in the measurement.

2. Measure the drop

The starting point depends on whether the curtains will hang from a track or a pole.

Measure vertically from the top of the curtain track to the selected finishing position.

Curtain track

Measure from the top of the curtain track down to the position where you want the curtain to finish. This allows the curtain heading to conceal the track.

If the track projects away from the wall, confirm that the curtain heading and hooks are suitable for the track.

Measure vertically from the underside of a curtain ring to the selected finishing position.

Curtain pole

Measure from the underside of the curtain ring down to the position where you want the curtain to finish.

Choose the finishing position

01

Sill length

Measure to approximately 1 cm above the window sill so the curtain can hang freely.

02

Below-sill length

Measure to the required position below the sill. A drop of approximately 10–15 cm below the sill is commonly used, provided there is no radiator or furniture in the way.

03

Floor length

Measure to approximately 1 cm above the floor for a clean finish without the curtain dragging.

Floors and window frames may not be perfectly level. Measure the drop at more than one point when necessary.

Measuring Guide

Before recording your measurements

Use a rigid metal tape measure rather than a fabric measuring tape.

Record all measurements in centimetres.

Always write the width first and the drop second.

Measure each window separately, even when the windows appear identical.

Measure at least twice before placing an order.

Do not make your own fitting deductions unless the product instructions specifically ask you to do so.

Check for window handles, radiators, furniture, tiles and other possible obstructions.
