Varnish Coverage Calculator — Wood Varnish Quantities
Calculate varnish quantities for floors, furniture, and woodwork based on area and coats.
How We Calculate This
Total coverage area = Surface area × Number of coats
Litres needed = Total area ÷ Coverage rate per litre
Oil-based polyurethane covers ~12 m²/L. Water-based covers ~14 m²/L. Always check the manufacturer's stated coverage.
