How Much Will a 12 Inch Cherry Panel Move
+0.1704" (+4.3 mm)
- Species: Black Cherry (tangential shrinkage 7.1%)
- Starting width: 12"
- Moisture content: 6% -> 12% (a typical dry-to-humid seasonal swing)
MethodΔD = D x ΔMC x (shrinkage% / 30 / 100)
Your actual humidity swing may be smaller or larger than the 6-12% MC example used here — run your own numbers in the movement calculator.
A 12" wide black cherry panel will grow about +0.1704" (+4.3 mm) across its width from 6% to 12% moisture content — one of the smaller movement figures among the domestic hardwoods this site tracks, though cherry's real reputation problem in the shop has nothing to do with swelling at all.
Why this one specifically
Cherry's tangential shrinkage (7.1%) sits below walnut and well below either oak, so panel gaps and seasonal movement are genuinely less of a headache with this species than the ring-porous hardwoods. What cherry is actually notorious for is photo-oxidation — the wood darkens and ambers noticeably within weeks of light exposure, uneven if part of a panel is covered by a runner or another object during that period. Builders who plan carefully for cherry's modest movement sometimes still get caught out by a two-tone panel from an unrelated cause.
What moves the number
Width scales this linearly, and grain orientation matters as much for cherry as for any other species — quartersawn cherry moves less than this flat-sawn tangential figure. Humidity swing size is the other real variable: a smaller seasonal RH change than the 6-12% MC example used here produces proportionally less movement.
