This is our curtain calculator and is based on very generic assumptions. It works out the amount of fabric required for standard curtains assuming you are using 35cm for hems, to the nearest width and then give you the number of pattern repeats.
We manufacture curtains and blinds, so if you want curtains then we can manufacture them for you using our range of curtains, so you do not have the stress of just buying fabric and finding a curtain maker. You can see our range of Made to Measure Curtains
All curtain makers use different amounts of fabrics in their curtains, we use 35cm for hems but others may use more or less. So please speak with a curtain maker to ensure you are correct
Pencil Pleat, Eyelet usually use 2 for fullness, Double pinch pleat and Triple Pinch Pleat will use 2.5x , Wave 80mm will be different again and has its own calculation
Direct Fabrics takes no responsibility on customers ordering the wrong amount of fabric

How to Calulcate the amount of Fabric for Curtains
Fabric Calculation for Curtains
Calculating the fabric required for making your curtains is quite simple once you know the maths formula. Please follow the steps below to ensure that you have the necessary fabric required before ordering your products. We recommend emailing the team before placing the order just for a final check.
We make all our curtains to double fullness unless otherwise stated.
1. Get the Width and Drop for your track and desired drop of your curtains
2. Get your fabric width - usually 137cm but can vary with velvets
3. Find Pattern Repeat.
Calculation
| 1) Calculating Number of Widths for Curtains | 2) Calculating the Drop for a Plain Fabric / or Pattrerned Plain |
Width of Curtain Track x 2 (TW) = Total Fabric Width TFW Divided by / Fabric Width (FW) = Widths Required Total eg. Track width = 200cm, Fabric width =137cm Required Amount = TW x 2 (200cm x 2) = 400cm 400cm (TWC) / 137cm (FW) = 2.91 Thus round up to 3 Widths. Thus 1.5 Widths per Curtain. | Drop required + 30cm for Hems eg. Finish Drop of Curtains 150cm + 30cm for hems = 180cm Pattern Pattern repeat of Fabric = 25cm Vertical Repeat Required drop including hems = 185cm Dequired Drop / Pattern Repeat = 185cm / 25cm = 7.4 Thus round up to 8 = Cut Lenth = 8 x 25cm = 200cm -- Therefore 15cm wasted. NOTE - Do not round down always round up. |
3) Total Fabric Required
Plain - No Pattern Repeat
No of Widths x Fabric per Drop including pattern repeats cut lenth
3 Widths per Above total x Drop Required inc patter Repeat 180cm = 540cm (5.4 metres)
Pattern
No of Widths x Fabric per Drop including pattern repeats cut lenth
3 Widths per Above total x Drop Required inc patter Repeat 180cm = 540cm (6 metres)
