Wok Size Calculator

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).
