How to Calculate Curtain Fabric Quantity
- Enter your pole or track length
- Enter the finished length of your curtain.
- Enter the width of your fabric.
- Enter the vertical pattern repeat of your fabric, (enter 0 for a plain fabric - see info button regarding half drop pattern repeats)
- Select whether your curtains are to be just LINED or INTERLINED as well
- Select whether calculating for a SINGLE curtain or a PAIR.
- Select your curtain heading type, either pencil pleat, double (pinch) pleat, triple pleat, goblet pleat or cartridge pleat.
- Enter the depth of your buckram ( enter 0 for pencil pleat heading as you will be using tape)
- Enter a desired fullness ratio (see info button for recommendations and our tutorials STEP 3 for more info)
- Decide whether you want to round down the number of widths (see info button and see calculator assumptions note 3 - calculator automatically rounds up if not selected )
- If you have a patterned fabric decide if you want to inclue an extra pattern repeat to position the pattern on the curtain (see info button for more details and what to do with half drop pattern repeats)
- Press Calculate
Note if you change any entries press calculate again to re-calculate.
Calculator Assumptions
- Curtains 1.5m or shorter have a fabric double 8cm hem, lining double 6cm hem.
- Curtains over 1.5m in length have a fabric double 10cm hem, lining double 8cm hem.
- Patterned fabric is a standard pattern repeat not a half drop pattern repeat.See HALF DROP PATTERN REPEAT CALCULATOR
- Calculator defaults to rounding the number of fabric widths UP to the nearest whole number. If the resultant Actual fullness ratio is too high select the option to round DOWN to the nearest whole number and re-calculate. Then check if this lower Actual fullness ratio is more suitable.
- 5cm trimming allowance on lining cut drops
- 10cm trimming allowance on interlining cut drops
- 5cm trimming allowance on plain fabric cut drops (note not included for pattern fabrics as adjusted cut drops are usually longer than required)
- Lining and interlining is assumed to be a similar width to the fabric.
This curtain fabric calculator is based on making curtains using the heading and hem allowances in our Curtain Courses. Full written explainations of the calculations the calculator is based on are given in the tutorials on this website.
NOTE: Our goal is to make the Fabric Calculator as accurate and helpful as possible, but please double-check all results thoroughly. (see terms).
