Home decorating calculators
Work out how much to buy before you start. Each calculator uses your own measurements and the details printed on the product, shows every step of the working and prints a plan to take to the shop.
- Wallpaper calculator
Rolls, strips and pattern repeat from your wall sizes, with a roll cutting plan.
- Paint calculator
Litres or gallons and whole cans for walls and ceilings, minus doors and windows.
- Baseboard & skirting calculator
Lengths of baseboard or skirting to buy, with a cutting plan that reuses offcuts.
- Flooring calculator
Boxes of laminate, vinyl or wood for one or more rooms, plus underlay and cost.
- Tile calculator
Tiles and boxes for floors or walls, plus grout and adhesive, with a layout preview.
- Square footage calculator
Floor area of any room in sq ft and m², including L-shaped rooms and bays.
- Room lighting calculator
Lumens, bulbs and an even downlight layout for a bright, comfortable room.
- Curtain fabric calculator
Fabric widths, drops and total metres or yards, with fullness, hems and repeat.
Buying too little means a second trip and, for wallpaper and tiles, the risk of a different batch. Buying too much wastes money. These calculators model the details simple area sums miss: full-height wallpaper strips and pattern repeat, coats and cans of paint, whole boxes of flooring and tile, fixed lengths of baseboard, and fabric widths for curtains.
Every result is an estimate. Measure carefully and check quantities with your retailer before you buy.
