Paint Quantity Calculator
Coverage is printed on every tin and it differs by product and surface — so the calculator lets you type it in rather than assuming one number for all paints.

Assumptions & limits+
- Money figures use MAYA's illustrative planning rates — an indicative estimate, not a quotation. A site-verified BOQ follows a consultation.
- Standard deductions applied: 21 sq ft per door and 15 sq ft per window.
- Purchase quantity includes a 10% allowance rounded up to whole litres.
- Putty, surface preparation labour and scaffolding are excluded from the material estimate.
Questions people ask
Is putty included?+
No. Putty depends on the wall condition; a painter estimates it on site.
Why buy 10% extra?+
Touch-ups, absorbent patches and the last half-tin that always runs short. Keep the extra sealed for later repairs.
Exterior walls?+
Choose Exterior emulsion — lower coverage on textured surfaces — and add the parapet and chajja areas.
