Enter the room size and pattern repeat. The standard UK roll is 10.05 metres long and 53 centimetres wide.
How this is worked out
Each drop is the wall height plus the pattern repeat plus an allowance for trimming. The calculator works out how many full drops fit on a roll and how many drops go round the room, leaving off some width for each door and window. Always buy rolls with the same batch number.
These are estimates for planning and ordering. Materials, bag sizes and densities vary by product, so always check the figures on the packaging or with your supplier before you order. For structural work, follow the advice of a qualified builder or engineer.
