Wok Size Calculator
Find the right wok size for your household.
Calculate the ideal wok diameter based on number of servings, stove type, and cooking style.
Choosing the right wok size is more important than most cooks realise. A wok that is too small causes ingredients to steam rather than stir-fry — the pan gets overcrowded, moisture builds up, and you lose the signature “wok hei” (breath of wok), that slightly smoky, charred flavour of authentic stir-fry.
The general rule for home cooking is to allow enough space for ingredients to move freely. A good stir-fry requires hot, dry surfaces making contact with every piece.
Recommended wok sizes by servings:
- 1–2 people: 28–30 cm (11–12 inches) — compact and heats fast
- 2–3 people: 32–33 cm (12.5–13 inches) — the most versatile size for home use
- 3–4 people: 35–36 cm (14 inches) — the standard restaurant home size
- 4–6 people: 38–40 cm (15–16 inches) — large family cooking
- 6+ people: 45 cm+ (18 inches+) — only suitable for commercial or outdoor wok burners
Stove type matters significantly. A standard flat-top electric or induction hob has a maximum ring diameter of about 22–28 cm. Using a 40 cm wok on a small ring means only the base gets heat — the sides stay cold and the wok hei effect is lost. For electric and induction: stick to 28–32 cm flat-bottomed woks. For gas: you can go larger since the flame wraps up the sides.
Carbon steel is the traditional and preferred material. It heats fast, develops a natural non-stick patina over time (seasoning), and gives you proper wok hei. Cast iron holds heat well but is very heavy. Non-stick coatings are discouraged for wok cooking — high heat destroys them and eliminates the charring effect.
Wok depth (height of the sides) matters too. A deeper wok helps contain splatters and allows tossing without losing ingredients. Standard depth is about 8–10 cm (3–4 inches).
