Paint Estimator — FAQs
Does the ceiling count?
No — this calculates walls only. Ceiling = length × width as a separate surface, usually in dedicated ceiling white.
Why might I need more?
New plaster, dark-to-light colour changes, and textured walls all drink paint — new plaster needs a mist coat (watered-down first coat) on top.
