Paint estimate notes
This assumes you are painting the four walls only. You can extend the formula later for ceilings, trims or feature walls.
Popular sizes
These paint presets target common wall sizes people use when checking how many litres they need before buying paint.
Paint buyers usually search by a recognisable wall size rather than by formula. Pre-filled pages such as 2m × 2.1m, 2m × 2.3m, 2m × 2.4m, 2m × 2.5m create direct landing pages that can rank for size-led queries while still keeping the calculator interactive.
