Coverage varies by stain type and wood porosity. Transparent stains cover more area than solid colors. Rough or porous wood requires more stain than smooth, sealed surfaces.

Stain Cost Breakdown
Deck Stain Calculation Formula
Gallons Needed = (Length × Width) ÷ Coverage per Gallon
The amount of stain needed is calculated by dividing your deck’s total square footage by the stain’s coverage rate. Always add 10-20% extra for waste, especially on porous wood or complex decks.
