How to Calculate Paint Needed?

To calculate the paintable wall area, multiply the room perimeter by the ceiling height. Door and window areas are subtracted from the total. Generally, 1 liter of paint covers approximately 10 m² (about 100 ft²).

Tips

Painting a light color over a dark one may require extra coats
Rough or textured surfaces use more paint
Two coats provide better coverage and durability
Standard door area: ~20 ft² (1.9 m²), window area: ~16 ft² (1.5 m²)
