Paint Mixture Needed
Paint pouring requires calculating the total volume to cover your canvas surface.
Surface area formula:
- Imperial:
Area = Width (in) × Height (in) - Metric:
Area = Width (cm) × Height (cm)
Paint volume needed:
The standard coverage is about 1 oz (30 ml) per 25 sq inches (161 sq cm).
Volume (oz) = Area (sq in) / 25
Volume (ml) = Area (sq cm) / 5.4
Typical paint-to-medium ratio:
- Standard pour: 1 part paint to 2 parts medium
- Thin pour: 1 part paint to 3 parts medium
- Thick pour: 1 part paint to 1 part medium
Add 20-30% extra for overflow (paint pouring requires excess to cover edges).
Color distribution: Divide total paint evenly across your number of colors, or customize ratios.
