How these numbers were sourced
MOE, SG (12% MC), Janka and shrinkage from The Wood Database (cites USDA FPL Wood Handbook). Cumaru is not listed in the FPL/Hoadley dimensional change coefficient table, so CT/CR are omitted. Uses, region, durability and workability summarized from The Wood Database. Price indicative.

These calculators are for planning and estimation. Engineering results (shelf sag, wood movement) use published average material properties; real boards vary by grade, grain, moisture and defects. Verify load-bearing designs with a professional.
