Room Size & Renovation Calculator

Before you start any renovation or redecorating project, knowing your material quantities is essential to avoid costly over-ordering or frustrating shortfalls. This free room calculator gives you accurate estimates for flooring (tiles, timber, and carpet with waste allowances), paint (walls and ceiling in litres and number of tins), wallpaper rolls, and the right number of downlights for your room type. Simply enter your room dimensions in metres or feet, add your door and window counts, and every calculation updates instantly. Whether you're planning a full renovation or just repainting, this tool saves you time and money before you visit the hardware store.
