Where to buy this
- 7.80 board feet of MahoganyHome DepotLowe's
Big-box stores carry a handful of species in nominal sizes; for anything else a hardwood dealer sells by the board foot, which is what this figure is in.
Plain search links, nothing sponsored. Prices and stock are the shop's, and a local lumberyard will usually beat both on solid stock.
Ask for
1 4/4 mahogany, 12 ft long and about 8″ wide
8.00 bf — 3% over what you need, and each board yields 4 of your pieces. Hardwood is sold random-width, so expect the yard to hand you something close rather than exact.
Working genuine mahogany
Stable, easy to machine, and it holds crisp detail better than almost anything — the traditional choice for carving and for doors that must not move. Genuine mahogany is CITES-listed; most of what is sold cheaply as 'mahogany' is sapele or khaya, which work similarly but are not the same wood. Ask what you're buying.

Mahogany questions
- How much does genuine mahogany cost per board foot?
- Roughly $16.00 per board foot for 4/4 stock, as a national ballpark last reviewed 2026-09-01. Regional supply, grade, width and whether you are buying from a hardwood dealer or a big-box store move this a long way — the calculator lets you type in your own price.
- How much does genuine mahogany weigh?
- About 37 lb per cubic foot at furniture moisture content, which works out to roughly 3.1 lb per board foot. The calculator estimates the weight of your order so you know whether it fits in the car.
- How hard is genuine mahogany?
- 900 lbf on the Janka scale. For reference, red oak is 1290 and is the usual benchmark for a hardwood floor; anything much under 1000 will show dents in a tabletop that gets used.
- How much does genuine mahogany move with the seasons?
- A 12" wide plain sawn board moves about 0.20" across its width over a typical seasonal swing, and roughly 72% of that if it is quartersawn. Design any solid panel wider than about six inches to float rather than be fastened at both edges.
- What should I know about working genuine mahogany?
- Stable, easy to machine, and it holds crisp detail better than almost anything — the traditional choice for carving and for doors that must not move. Genuine mahogany is CITES-listed; most of what is sold cheaply as 'mahogany' is sapele or khaya, which work similarly but are not the same wood. Ask what you're buying.
