New painters buy too much or too little paint because they guess coverage instead of calculating area.
Estimate paint volume needed for a canvas, with extra for two coats and edges.
Acrylic and oil painters preparing for a new piece.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Measure width and height in centimeters, including edges you plan to paint.
Plan for at least two coats for even coverage.
Add extra if you paint the sides of the canvas.
It is easier to waste a small amount than to stop mid-painting to mix more.
A 40×50 cm canvas with two coats and edges needs about 30 ml of acrylic paint for a standard layer.

What this source supports: Coverage rates for paint vary by thickness, substrate, and application; thin acrylic layers cover roughly 100–150 sq ft per gallon.
Source limit: Thick impasto, absorbent surfaces, and thinned paint change coverage dramatically. This is a rough estimate.
