Wood Stain Coverage Calculator
Label coverage (m² per liter) is usually per single coat, so multiple coats multiply the amount needed. Rough wood or a lot of exposed end grain soaks up more than the label rate suggests.
Your numbers
Stain needed
0.6L
Formula
Stain needed = Area to stain × Number of coats ÷ Coverage rate
The first coat often uses 20-30% more than the label rate since bare wood absorbs the most. Buy a bit extra rather than running short mid-coat.

Frequently asked questions
QHow is Wood Stain Coverage Calculator calculated?
Stain needed = Area to stain × Number of coats ÷ Coverage rate — Label coverage (m² per liter) is usually per single coat, so multiple coats multiply the amount needed. Rough wood or a lot of exposed end grain soaks up more than the label rate suggests.
QCan you walk through an example?
With Area to stain 3m², Coverage rate 10m²/L, Number of coats 2coats, the answer is Stain needed 0.6L.
QWhat do I need to enter?
Enter Area to stain, Coverage rate, Number of coats. The result recalculates as you type, and an empty box counts as zero.
QHow much does the answer move if I change a number?
Changing only Area to stain (m²) moves the answer to Area to stain (m²) 1.5 → Stain needed (L) 0.3 and Area to stain (m²) 6 → Stain needed (L) 1.2. The table below lays out five steps.
QHow are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
QAnything to watch out for?
The first coat often uses 20-30% more than the label rate since bare wood absorbs the most. Buy a bit extra rather than running short mid-coat.
