Doing It Yourself

In this section you will find plenty of advice and information on measuring and fitting your curtains and blinds. Whatever you need to know, from deciding on how much curtain fabric you require to measuring your curtains for pelmets and valances.

We know how important it is for you to get curtains and blinds that fit perfectly and in just the way you want, which is why we have provided this information. If you would rather have the job of measuring and fitting done by an expert, contact us to discuss our blind and curtain fitting services.

How Measure for Made to Measure Blinds

Blind Size or Recess Size

When measuring for made to measure blinds, you need to consider the space available and the position of your window before deciding whether to fit the blind in the recess of the window or on the outside. When measuring always use a metal tape measure and use centimetres (cm) or millimetres (mm).

Recess Size

If measuring for a recess blind, measure the recess width and drop in 3 places and pick the narrowest width and the shortest drop if your window is out of shape.  Also when choosing how far forward in the recess you want the blind, you need to make sure that the blind will clear any handles.

Blind Size

These blinds are fitted to the outside of the window, they will be larger than the window, as the blind will hang from above the window and will be wider and sometimes longer than the window itself, a general rule of thumb would be to measure from 3" (7.5cm) above the window and the same either side of the window, Although if a window is short and light an issue, plus you have space above the window, the blind can be fitted higher to give an illusion of the longer window.

How to measure curtains on existing fittings

Taking measurements from existing tracks and poles is quite straightforward.

Measuring for Tracks

Measure the width of the track, allowing 7.5cm (3") overlap in the middle.  Measure from the top of the track and not the runners, as if you measure from the runners the curtains will not cover the track when pulled, to the floor, or if a short window to 12-15cm under the window sill.

Measuring for Poles

Measure the width of the pole between the finials, allowing for a 7.5cm (3") overlap (if the pole has a central bracket this allowance will need to be slightly larger), plus returns if you wish to return the ends of the curtain to the wall.  Measure from the bottom of the ring to the floor, or 12-15cm below the sill.

Where to fit your Track or Pole

Fitting Curtain Tracks

Generally tracks are fitted approximately 7.5cm (3") above the reveal and will continue pass the side reveals by 15cm (6"), you can of course come pass the sides of the window as much as you wish if you have the space.  Although when the curtains stack back at the sides you really want them to cover the sides of the window. Measure for your curtains and same as above.

Fitting Curtain Poles

Poles are fitted slightly higher above the reveal, as the curtains will hang under the pole, approximately 12.5 cm (5") above the reveal, and will continue pass the side reveals by 15cm and then the finials.  Measure for curtains the same as above.

How Much Fabric do I need?

To calculate the amount of fabric you need for curtains, take the width of the track and multiply by 2, 2.5 or 3 times for fullness, divide this number by the width of the fabric, this will give you the number of farbic drops fro your curtains, divide this by 2 and you have the number of drops per curtain.  To calculate the length of drops, take the finished length of the curtains and add 25cm (10") for the hem and turnover at the top.  If a pattern fabric divide by the pattern repeat and the number of full pattern repeats will be your cut drop length.  Multiply the cut drop length by the number of drops and this will give you the amount of fabric you need to make your curtains.

What about Valances and Pelmets

Measuring for Valances

Measure the length of the valance track and returns and multiply by the same formula as used above for working curtain fabric out and the number of widths, you will also need to take into consideration on patterned fabrics how the pattern is going to sit on the valance.

Measuring for Pelmets

Measure the length of the pelmet board, including returns, if more than one width of fabric is required do not put a seam in the middle, so if two widths are to be used but one width in half and join both sides of the other width and centralise to the middle of the board.  Rember again with pattern fabric the positioning of the pattern on the pelmet.

Cutting Roller Blinds

Measure the width of the window that you wish the blind to fit.  Unpack the roller blind and slot in the chain guide and roller guide, then fit the brackets into the ends and measure total length. Minus the window width from the blind/bracket width, the difference in the two measurements is the amount to be cut from the roller and blind, plus an extra 5mm from the blind.

First, unroll the roller blind on a flat surface and remove the bottom bar, with a ruler and a pencil, mark on the blind the amount to be cut off and draw a cutting line.

Example, blind width with brackets 122cm, minus window width 115cm, the difference is 7cm plus the 5mm to be deducted from the blind, so cut off 7.5 cm.

Once you have marked you measurements and drawn a line along the side of the blind, cut the blind, once you reach the roller, peel the blind back and then cut to the end.  Next, cut the roller using a hacksaw with a sharpe blade, then cut the bottom bar and slot it back into the blind.

Once you have place the guides back into both sides of the blind you are ready to fit.
