Built for Australian homes

How much paint, flooring or tiles do you actually need?

Free indoor calculators in square metres and litres — not guesswork. Work it out in seconds, order the right amount, avoid a second trip to Bunnings.

The calculators

Four live calculators

Litres of paint for any room. Handles walls, ceiling, doors and windows — with coats and waste margin.

Square metres, tile count and boxes for any room. Works with standard AU tile sizes and plank flooring.

Number of rolls for a room or feature wall, accounting for pattern repeat and door/window deductions.

Recommended kW capacity for a room or open plan area — matched to AU climate zones.

Every calculator uses square metres, litres and millimetres — the units on the tin, the box and the invoice.

Type your numbers in. Get your answer. Leave. We don't want your email and we're not sending a newsletter.

Built for standing in a room with a tape measure in one hand. Big inputs, clear outputs, no pinch-to-zoom.

Every result adds a sensible waste margin and explains why. Order enough the first time.
