How Many Ribs Should a Tuan Shan Have? The Count That Shapes the Fan
The tuan shan's character is set before any painting is applied: by how many ribs carry the paper. Traditional fans range from a spare 12 ribs to a dense 20 or more, and that number decides weight, how far the fan spreads, and how it feels when you open it. Rib count is the spec most buyers never read — and the one that matters most for daily use.
The Scenario: A fan that felt wrong in the hand
A buyer chose a tuan shan at a market by its painted surface alone. At home, the fan felt heavy, opened too stiffly, and the paper pulled away from the edge when fully spread. The painting was beautiful; the structure was wrong for her hands.
Pain Points
- Looks dominated the decision; structure was ignored;
- A stiff, heavy fan tires the wrist during daily use;
- Paper tension depends on rib spacing — the wrong count makes the fan sag or strain at the edges.
The Solution: Choosing by rib count, matched to use
1. 12–14 ribs — the light daily fan Thin, widely spaced ribs keep the fan light and flexible; the arc is narrower, ideal for everyday carry, quick fanning, and delicate painted scenes that need to breathe.
2. 15–18 ribs — the balanced classic The most common range for a reason: enough ribs for a full arc and sturdy spread, light enough for comfort. The sweet spot for most buyers and most artworks.
3. 19–22 ribs — the full, formal arc Denser ribs give a wider, sturdier arc and a heavier, more deliberate feel — suited to display fans and formal occasions, less ideal for constant wrist work.
4. Match the paper to the count A wider spacing (fewer ribs) needs stiffer paper to hold tension; a denser rib set lets thinner paper lie flat. Ask the maker how the two were matched.
The Result: A fan that opened like it belonged
The buyer returned the heavy fan and chose a 16-rib classic with a matched stiff paper. It opened with an even arc, held its tension through the day, and the painting no longer strained at the edges. She now asks one question before any purchase: "How many ribs, and how is the paper matched?"
