Most surfaces need around 1 litre per 10m² per coat. A standard bedroom with 4 walls at 2.7m high typically needs 8–10 litres for two coats. Always allow 10–15% extra when buying.
Getting your paint estimate right before starting a project saves time and money. Buy too little and you risk running short mid-job. Our free paint calculator helps Gold Coast homeowners estimate quantities based on room dimensions, number of coats and surface deductions for windows and doors.

Paint Buying Tips
Rough surfaces absorb more paint
Unpainted, porous or textured walls soak up more than sealed surfaces. Add extra for first-time painting.
Dark colours often need 3 coats
Changing to a significantly darker shade typically requires an extra coat over the standard two.
Check the product label
Coverage rates vary by brand and finish. Premium paints often cover more per litre than budget options.
Keep leftover paint for touch-ups
Even a small amount of leftover paint is useful for repairs after furniture moves or minor wall damage.
