SquareMate: DIY Material Calc

Stop guessing in the DIY aisle. SquareMate works out exactly how much material a job needs — paint, tiles, wallpaper, gravel, decking and more — with standard waste allowances built in, so you buy the right amount the first time.

Enter the size of the room, wall or garden bed, and SquareMate does the maths.

19 CALCULATORS FOR HOME AND GARDEN

• Paint — litres and cans, with windows and doors taken off

• Floor tiles — tiles and boxes, allowing for grout gaps and waste

• Wall tiles — for walls and splashbacks

• Wallpaper — rolls, allowing for pattern repeat

• Laminate — packs, laid straight or on the diagonal

• Paving — slabs, plus sand and cement for the base

• Decking — boards and total board length

• Plasterboard — boards per wall

• Concrete — slabs, columns and footings, from premix bags or cement, sand and gravel

• Gravel — bags, volume and weight

• Bark mulch — bags for rectangular, round or triangular beds

• Turf — rolls for rectangular or round lawns

• Fence — posts, rails, boards or panels, and post mix

• Skirting & trim — lengths to buy, with offcuts at every corner

• Insulation — rolls or boards, in one or more layers

• Screed & levelling — sand and cement, or bags of self-levelling compound

• Tile adhesive & grout — bags of adhesive and grout for your tile size

WHOLE ROOMS, ANY SHAPE

• Enter a room once and get paint, flooring, skirting and wallpaper together

• Rectangular, L-shaped, or several parts added together

• Save the whole room to a project in one tap

SEE THE CUTS BEFORE YOU BUY

For tiles, paving, laminate, decking, plasterboard and wallpaper, SquareMate draws the layout: which pieces go down whole, which need cutting, and how wide the edge cuts will be.
