This tutorial is based on using one width of fabric or lining to make a blind. Lining is usually approx 137cm wide, so most blinds less than 137cm wide will only need one width of lining (check your lining width).
The lining panel is cut to the following size to make the blind:
If you are using rod pocket tape RPA=0, please see ROD POCKET TAPE notes below.
LINING QUANTITY REQUIRED
The minimum amount of lining required to make a single width roman blind is the LINING CUT DROP + TRIMMING ALLOWANCE

The Blackout panel is cut to following size to make the blind: For COMBINED BLACKOUT/INTERLINER please see the extra instructions at the bottom of the page.
BLACKOUT QUANTITY REQUIRED
The minimum amount of Blackout required to make a single width roman blind is BLACKOUT CUT DROP + TRIMMING ALLOWANCE

To help check your results and make the process easier or if you don't like maths we've made this calculator for calculating Roman blind fabric and lining quanities.
EXTRA INSTRUCTIONS
COMBINED Blackout/Interliner is cut to a different size to standard Blackout to make the blind. Due to it's thickness it is not folded into the hem. It is cut slightly (2mm) narrower and shorter than the blind to fit inside the fabric. The cut size is:
COMBINED BLACKOUT/INTERLINER QUANTITY REQUIRED
The minimum amount of Combined Blackout/Interliner required to make a single width Roman blind is COMBINED BLACKOUT/INTERLINER CUT DROP + TRIMMING ALLOWANCE
PRO TIP: Add at least an extra 6cm trimming allowance to the cut drop to ensure that the blackout can be cut square during the making process.
Extract from our ROD POCKET TAPE EXTRA Tutorial
If you are using Rod Pocket Tape you will need to disregard the rod pocket allowance as you will not be making the rod pockets out of the lining. Therefore the ROD POCKET ALLOWANCE (RPA) = 0 when calculating the LINING CUT DROP.
