Calculate how much finish you need for a woodworking project based on surface area, finish type, and number of coats.
Surface Area
Enter the total surface area to be finished. For furniture with multiple faces, multiply the single face area by the number of sides.
Finish Type
Open-grain woods like oak absorb more finish on the first coat.
Spray application uses more finish due to overspray. Wipe-on applies thinner coats and uses less per coat.
