From 20cm to 30cm, every frying pan size has a purpose. Learn which sizes you actually need and how to choose the right pan for the way you cook.
Why Size Matters More Than You Think
Using the wrong size frying pan is one of the most common kitchen mistakes. A pan that is too large wastes energy, causes oil to spread too thin, and leaves empty areas that overheat and smoke. A pan that is too small overcrowds food, traps steam instead of allowing it to escape, and prevents proper browning. Choosing the right size means better searing, more even cooking, and less wasted energy. Most home cooks need just two sizes to cover every situation.
The 20cm Pan: Singles and Small Tasks
A 20cm frying pan is the perfect size for cooking one or two eggs, toasting spices, making a single portion of sauteed vegetables, or reheating a small amount of leftovers. It heats quickly, uses minimal oil, and is light enough to flip with one hand. If you live alone or frequently cook individual portions, a 20cm pan earns its place as your everyday workhorse. It is also the ideal size for making omelettes, as the smaller surface area gives you the depth needed for a proper fold.
The 24cm Pan: The Everyday Essential
If you could only own one frying pan, make it a 24cm. This is the most versatile size in any kitchen. It comfortably fits two chicken breasts, a full stir-fry for two, a couple of salmon fillets, or a generous portion of sauteed greens. The 24cm size strikes the ideal balance between cooking surface area and manoeuvrability. It is large enough for most meals but small enough to handle comfortably with one hand. SEIDO's 24cm stainless steel pan with ThermoCore 5-ply base is designed around this principle.
The 28cm Pan: Family Cooking
When you are cooking for three or more people, a 28cm pan gives you the space to sear without overcrowding. Four chicken thighs, a large batch of stir-fried noodles, or a full English breakfast all fit comfortably. The larger surface area also makes it the right choice for one-pan meals where you need room for protein, vegetables, and sauce together. The trade-off is weight and storage — a 28cm pan is heavier and needs more cupboard space, so it works best as a complement to a smaller pan rather than your only option.
The 30cm Pan and Beyond
Pans larger than 28cm are specialist tools. A 30cm pan is useful for entertaining, cooking large batches, or preparing paella-style dishes. However, most domestic hobs struggle to heat a 30cm pan evenly because the burner is smaller than the pan base. This creates a hot centre and cool edges. If you regularly cook for five or more people, a 30cm pan has its place, but for most households it is an occasional-use item rather than a daily essential.
Building Your Pan Collection
For most kitchens, the ideal combination is a 24cm pan for everyday use and a 28cm pan for larger meals and batch cooking. Start with the 24cm and add the 28cm when you find yourself needing more space. If you cook for one most of the time, swap the 28cm for a 20cm instead. Invest in quality for the size you use daily — a well-made 24cm pan with a 5-ply base will outperform a cheap pan of any size and will last decades rather than years.
