How to Measure
We have created this page in order to help you measure your windows prior to placing your order for readymade curtains with Millers Home. All of our readymade curtains are manufactured with a multi-pocket heading tape which allows the readymade curtains to be fitted on different styles of curtain tracks and rods. Please be aware that readymade curtains are not custom made and for this reason some variances in length may occur.
For accurate measurements we suggest using a metal tape measure as cloth tapes are not always precise, and to measure the window frame or existing curtain track or rod rather than measuring existing curtains.
To get started you will need a pen and paper ready and, if possible, another person to help you. As it is very easy to transpose measurements clearly indicate on your notes which measurement is the width and which measurement is the length. A simple “W” for width and “L” for length can ensure the correct size readymade curtains are purchased, affording you the best possible fit. Moreover, make sure you have carpets or flooring in place before you measure. If this is not possible, then make allowances for the depth of the flooring, making sure to include the underlay if carpet is to be laid.
It is easy to measure up for curtains if the curtain track or rod is already in place. If this is the case, always measure the curtain track or rod, not the window. If fitting a new curtain track or rod, where possible, this should extend 20cm to 30cm either side of the window so that the curtains can be stacked back off the window. The curtain track or rod should sit either on the top of the architrave, or approximately 10cm to 15cm above the window frame or where there is good fixing for the brackets.
To arrive at the proper width of your window, measure across the window frame from one outside edge to the other (see diagram above) and then add on the distance the curtains will extend beyond the window, approximately 20 to 30cm on either side.
Measure from end to end.
Width = A to B
Cord Drawn Tracks
For a cord drawn track or rod, measure the maximum length of the track including any returns or overlaps (see diagram below). Measure the width of A to B and C to D individually and then add the two together to get the total width.
Width = (A to B) + (C to D)
When you are measuring existing curtain rods, do not include the length of the finials (decorative ends of the rods). However, if there is not an existing rod and you would like to purchase one make sure you are aware of the length of the finials, particularly if space is a factor, for example, if the window spans from wall to wall.
Width = A to B.
Measuring Drop (Finished Length)
The curtain drop is the length from the top to the bottom of the curtain. The drop will depend on where the base of the curtain is to finish, that is at the sill, below the sill or to the floor. We recommend that in order to maintain the greatest insulation curtains should be hung either to the floor, or below the sill, thoroughly covering the window and preventing hot air from escaping. If they are to hang below the sill then 20cm below is usually a suitable amount, although this is dependent on your window dimensions and the size of the readymade curtains. When using a curtain track, always measure from the top of the track to where the curtain is to finish, this will ensure that the top of the track will be hidden by the curtains.
When using a curtain rod, measure from the underside of the decorative ring to where you want the curtain to finish (as shown in the diagram below).
You are able to hang your readymade curtains at whichever length you prefer. Below is an illustration of the different length options available. This diagram assumes the curtain track or rod is to be mounted above the window frame, it can however be mounted wherever is suitable, including on the architrave.
A = Floor Length
B = Below the Sill
C = To the Sill
