How Much Does a Litre of Artist’s Paint Cover?

Worked Example: A 60 × 80 cm Canvas

A 60 × 80 cm canvas is 0.6 × 0.8 = 0.48 m². Two coats of acrylic means covering 0.96 m² of paint area; at 8 m² per litre that is 0.96 ÷ 8 = 0.12 litres, or 120 ml, and about 132 ml with the recommended 10% wastage for palette residue and mixing losses. Put another way, a standard 60 ml tube at 8 m²/L covers 0.48 m², almost exactly one thin coat over that canvas, and a full litre manages about 16 canvases of this size in a single thin coat (8 ÷ 0.48 ≈ 16.7).

Gesso and Oil for the Same Canvas

Priming first: 2 coats of gesso at 8 m²/L per coat is 0.96 ÷ 8 = 0.12 L, so 120 ml, or 180 ml for the 3 coats recommended under oils. The first coat always drinks more because it soaks into the raw canvas. Painting in oils instead of acrylics, the same two coats need 0.96 ÷ 6 = 0.16 litres, or 160 ml(176 ml with 10% wastage). Size those jobs precisely with the gesso coverage calculator.

Why Real Coverage Is Usually Lower

The table figures assume paint brushed out thin on a primed surface. Heavy-body acrylics resist brushing out, transparent and light colours over a dark ground need extra coats, and impasto or palette-knife work uses many times more paint per square metre. Treat the rates as a best case: bump up the coat count for opaque coverage, or enter your own brand’s m²/L from its datasheet as a custom rate in the paint coverage calculator. On cost, remember tube paint is expensive per litre: a 60 ml tube at £6 works out at about £100 per litre, which is why large-format painters buy pots.
