What size frying pan do I need? 8.5, 10, 11 or 12 inch
By KAJI · November 7, 2026
The number on the box is not the cooking space
Frying pans are sold by the size of the rim, measured across the top. But the walls slope, so the flat part where food actually sits is smaller, often by 2 to 3 inches. That flat surface is what decides how many eggs, fillets or steaks fit at once.
It matters because food needs space. Crowd a pan and the food releases water, steams instead of browning, and is more likely to stick. As a rule of thumb, leave a finger’s width between pieces.

Pick by how many you cook for
8.5 inch (22 cm): eggs, one or two people
Two eggs, an omelette, one chicken breast, a grilled cheese, toasting nuts or spices. It heats up fast, is the lightest of the four and is easy to store. On its own it gets tight for a full dinner for two. See the 22 cm.
10 inch (26 cm): two people
Dinner for two, three eggs, a chicken breast with vegetables. A little lighter and quicker to heat than the 28 cm. See the 26 cm.
11 inch (28 cm): three or four people, the everyday pan
Two steaks or two salmon fillets side by side, three or four eggs, a stir-fry for two, sautéed vegetables that brown instead of steaming. If you only buy one pan, this is the one. See the 28 cm.
12 inch (30 cm): four people or more
Family dinners, six chicken thighs at once, a big batch of vegetables, shallow braising. It is the heaviest of the four, so think about where you will store it. See the 30 cm.
Pick by what you cook
- Mostly eggs and breakfast: 22 cm.
- Steaks, fish and weeknight dinners for two: 28 cm.
- Batch cooking, meal prep or a big family: 30 cm.
- A bit of everything: 28 cm, plus a 22 cm for eggs and sides.
Check your burner and your storage
A pan heats best when its base roughly matches the burner or the induction ring under it. A 12-inch pan on a small burner stays cooler at the edges. If your largest burner is small, the 28 cm is usually the safer choice. All four KAJI sizes work on gas, electric, ceramic and induction.
Measure your cupboard too: with the handle, the pans are about 16, 18, 19 and 20 inches long.
When two pans beat one big pan
One very large pan is not always the answer. Two pans let you cook the main and the side at the same time, and the smaller one is much quicker for everyday eggs. The most common pairing is a 22 cm with a 28 cm.
Our Duo pairs the 22 and 28 cm, each with its glass lid, for less than buying them separately. The Trio adds the 26 cm, and the Complete Set covers all four.
Quick questions
Is a 12-inch frying pan too big?
Not if you cook for four or more, or like to cook in batches. For one or two people it is more pan than you need, and it is heavier to handle and to wash.
What size frying pan is best for eggs?
An 8.5-inch (22 cm) pan for one to three eggs, an 11-inch (28 cm) for four or more. On a titanium pan, preheat for a minute first. Read how titanium compares with nonstick.
What is the most popular frying pan size?
The 11-inch, or 28 cm. It is the size most home cooks reach for every day, which is why it is our reference size.
Can I return a pan if the size is wrong?
Yes. Every Kajipan comes with a 360-day trial, and return shipping is free within the first 30 days.
