How it's calculated (visible formula)

area = length × width; paint = area ÷ coverage × coats; cans = ceil(paint × (1 + waste) ÷ can size)

Net geometric measurement, no waste.
Adjustable waste % for cuts and breakage.
Purchase rounded up to sellable units (boxes, bags, buckets, boards).

How to calculate it, step by step

Measure ceiling length and width.
Check coverage per coat on the can.
Decide coats (two on new ceilings or color changes).
Work out gallons with waste.
Round up to full cans.

Worked example: 13 × 10 ft ceiling, 400 sq ft/gal, 2 coats

130 sq ft ÷ 400 × 2 ≈ 0.65 gal (2.4 l)
+10% ≈ 0.7 gal

→ One 1-gallon can.

Common mistakes

Using wall paint — more spatter and worse coverage overhead.
Skipping stain-blocking primer on water marks.
Rolling parallel to the window (lap marks show).

Pro tips

Paint the ceiling before the walls.
Protect floors and furniture and cover outlets and switches.
Use a medium-nap roller on an extension pole.
Cut in the edges with a brush, then roll.
