In-depth explanation
Estimate rolls from total wall width, height, and roll size by counting how many drops fit on each roll. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
One vertical strip of wallpaper from ceiling to floor (or skirting). Large repeats waste more paper — increase the wastage percentage or buy an extra roll.
Many UK rolls are about 530 mm wide and 10 m long — defaults use that. Tweak the inputs above to compare options, then copy or note the result you need.
