Board Foot Calculator: Lumber

Calculate board feet and estimate lumber cost in seconds—at the lumberyard, in the workshop or while planning your next woodworking project.

Board Foot Calculator: Lumber is a focused, offline tool for woodworkers, furniture makers, carpenters, sawmill customers and DIY builders. Enter a board's actual thickness, width, length and quantity to get an instant board-foot result.

BUILD A COMPLETE LUMBER TALLY

Add multiple boards to a running tally instead of calculating every board separately. Your tally stays on your device so it is ready when you return.

ESTIMATE THE REAL PURCHASE

Enter a price per board foot to calculate lumber cost. Add a waste allowance to see how many board feet you should plan to buy and what the estimated total will be.

MADE FOR REAL LUMBER MEASUREMENTS

PRIVATE AND RELIABLE

The app works offline, requires no account and does not send your lumber data anywhere. Your saved tally remains locally on your device.

For rough-sawn hardwood, use the board's actual dimensions for the best estimate.
