Before you pick it up
The whole load. All 38 lb of it. Worth checking against what the car is rated to carry before you drive to the yard, and worth knowing before a freight quote.
Before you drill. The shelf itself is 10 lb before anything goes on it. Size the hardware for the shelf plus its load, fix into framing rather than drywall anchors wherever the two disagree, and remember that a floating shelf loads its bracket as a lever — the further out the weight sits, the harder it pulls at the wall.
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 weigh?
- About 37 lb per cubic foot kiln dried, which is roughly 3.1 lb per board foot. Green off the mill it is far heavier — around 50 lb per cubic foot at 60% moisture content, because most of that extra weight is water.
- Does genuine mahogany get much lighter as it dries?
- Yes. At 60% moisture content it runs about 50 lb/ft³; air dried to 12% that falls to 38, and kiln dried to 7% to 37. If you are hauling freshly sawn lumber, work from the green figure — the difference is real weight in the back of the truck.

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.
- How much weight can a floating shelf hold?
- That depends entirely on the bracket and what it is fixed into, not on the shelf. What this calculator tells you is the part people forget: what the shelf weighs before anything goes on it. A 48" × 10" × 2" solid oak shelf is around 23 lb empty. Size the hardware for the shelf plus its load, fix into framing rather than drywall anchors, and remember that a floating shelf loads its bracket as a lever — weight at the front edge pulls far harder than weight at the wall.
- What's the difference between board feet and weight?
- Board feet measure volume and are what you are charged for; weight is what you have to carry and ship. They are related by the density of the species, which varies by more than two to one across common woods — a board foot of white pine is about 2 lb and a board foot of hickory is about 4. Two orders of identical board footage can differ by a hundred pounds.
- How do I estimate freight for furniture?
- Start with the weight of the wood, then add the joinery hardware, the finish, and the crate — a plywood crate with bracing often adds 30% to 50% to the shipping weight of a table. Freight is usually billed on the greater of actual weight and dimensional weight, so a large light piece can be charged as though it were much heavier. Get the number here, then ask the carrier what they will actually bill.
