Leopardwood — Density, Movement, Workability & Cost

Cut leopardwood (Roupala montana) a few degrees off true quarter and the entire reason to buy it disappears — the large ray fleck that gives this species its name and its value only shows on a properly quartered face, and drift even slightly off that angle and the pattern washes out almost completely.

A wood defined by its rays, in more ways than one

At 55 lb/ft³ and 2,150 lbf on the Janka scale, leopardwood is dense and hard, and its large medullary rays — the structures responsible for the flecking pattern — create a second, less welcome effect: a tangential:radial ratio of 2.5, the highest among this site's exotic species, which means flatsawn leopardwood cups badly. That's a second, independent reason to insist on quartered material beyond the figure alone.

The movement number on the "stable" axis, which still isn't small

Radial shrinkage of 3.5% against a tangential figure of 8.8% gives that 2.5 ratio. Even on the better-behaved radial axis, a 6"-wide quartersawn panel gives up about 0.035" (0.9mm) across its width on the swing from 11% moisture content down to a dry 6%; the wood movement calculator covers other widths. That same panel, 1/4" thick and 2 feet long, weighs about 1.15 lb as veneer backing — the wood weight calculator covers other panel sizes.

Gluing with the rays working in your favour, and a texture to plan around

Gluing benefits directly from the large rays, which give a joint substantial mechanical key beyond what a straight-grained wood's surface offers — a genuine structural advantage from the same feature that causes the movement problem. On finishing, the rays sit slightly proud of the surrounding surface after the first finishing pass regardless of filler choice, and a final light cut-back is standard practice to level them before a topcoat goes on.

Durability, cost, and where the ray fleck pays off

Leopardwood is rated moderately durable, priced at roughly $22 per board foot — this site's premium tier. Veneer and marquetry, furniture accents, guitar bodies, turnery, and jewellery boxes round out its markets — every one chosen specifically for the ray fleck, since nothing about leopardwood's working properties alone would justify the price over a plainer, similarly dense alternative.

A name shared with more than one wood

"Lacewood," the broader trade term leopardwood sometimes travels under, is applied to several unrelated species sharing the same large-ray quartersawn figure — Australian silky oak and some Panopsis species among them. A buyer who specifically wants this species, rather than any large-ray lookalike, should confirm the botanical name rather than trusting "lacewood" alone.

What people actually ask about leopardwood

Is there a way to verify a supplier's "quartersawn" claim on leopardwood before an order ships, rather than discovering the problem after delivery? Asking for a photo of the actual end grain on the specific boards being sold, not a stock catalog image, is the practical safeguard — true quarter shows growth rings running close to perpendicular to the face, which a supplier can photograph in seconds and which settles the question before the material is committed to.

Does leopardwood cost more or less than American sycamore's lacewood figure for a comparable project? Leopardwood generally commands a real premium over domestic lacewood sycamore, since it's an imported exotic with its own density and durability profile, while sycamore is a considerably more affordable domestic hardwood that happens to share the same ray-fleck visual trick when quartered.

Why do the rays feel raised even after I've sanded the surface flat? Ray tissue and the surrounding wood can shrink or compress slightly differently during finishing, leaving the denser ray structure sitting proud — a final light sanding or scraping pass after the finish has had time to cure typically levels it.

Is leopardwood a good choice for a guitar body given its density? Its weight and hardness put it closer to a dense tonewood like bubinga than a lightweight body wood, so it suits builders after a bright, focused tone and are comfortable with a heavier finished instrument rather than anyone prioritising a light, resonant build.

The USDA Forest Products Laboratory's Table 4-4 has no entry for leopardwood, which is why the density, Janka hardness and shrinkage figures above all trace to The Wood Database's own 12%-moisture-content testing.
