Plan 8–12 pieces per person for a dim sum meal, with 10 being the standard. For a varied selection, serve 3–4 different items with 2–3 pieces of each per guest. Appetites vary, so add 20% extra for a generous spread.
Steamer capacity depends on diameter and item size. An 8-inch steamer fits about 4 standard dumplings per layer, a 10-inch fits 6, and a 12-inch fits 9. Larger items like char siu bao need more space, reducing capacity by about 30%.
| Steamer Size | Diameter | Pieces/Layer | Best For |
|---|---|---|---|
| 8 inch | 20 cm | 4 | 1–2 people |
| 10 inch | 25 cm | 6 | 2–4 people |
| 12 inch | 30 cm | 9 | 4+ people |
Steam times vary by item: har gow and siu mai take 8–10 minutes, char siu bao needs 12 minutes, cheung fun just 5 minutes, and lo mai gai (sticky rice) requires 20 minutes. Plan batches so quicker items come out first.
Yes, stacking 2–3 layers is standard practice and does not significantly increase cooking time. The steam circulates through the bamboo gaps. Place items needing more heat on the bottom layer and delicate items on top. Above 3 layers, the top layer may need extra time.
