How it works

  2. 2Area = π × (10.16)² = 324.3 cm²
  3. 3At 50-85cm² per serving, serves 4-6 people

Cake "inch" means inch (2.54cm), NOT the Chinese shi-cun (3.33cm) — the area differs by ~72%. Always confirm the cm diameter with the bakery.

50-85cm² per serving: pick the high end if served as a meal, low end if after dinner. When in doubt, size up.

Cutting guide: 6in→6 pieces, 8in→8, 10in→12, 12in→16. A two-tier cake serves roughly 1.8× a single tier.

Some shops shrink the diameter; measure on arrival — an 8in cake should be ≈20.3cm across.
