Merantis
Hardness among the 3 merantis here ranges from 460 lbf (Light red meranti) to 780 lbf (Dark red meranti). The flattest-drying is Light red meranti; the stiffest is Dark red meranti.
- Its median hardness, 770 lbf, is 41% below the median for imported woods.
- Every one of the three has a T/R ratio above the median for all 155 woods (1.81), so flatsawn boards of this family tend to move unevenly.
- One of the three is in the softest quarter of the 155 woods (up to 565 lbf); the rest sit in the middle half.
- Density runs from a specific gravity of 0.34 in light red meranti to 0.46 in dark red meranti.
- 770 lbfmedian hardness
- 0.46median density
- 11,400 psimedian bending strength
- 8.0%median face shrinkage

Ranked by hardness
Hardest first. Density is specific gravity; shrinkage is volumetric, green to oven-dry.
