So we know that the frypan is generally smaller than the skillet, but does that also mean it has a smaller cooking surface? It sure does. Its overall smaller build gives it a smaller cooking surface, while its shallower depth also reduces the amount you can cook on it. But its compact size certainly gives you an easier time when it comes to cooking smaller portions.

Pans are measured according to the diameter of the lip, not the diameter of the cooking surface. Most home burners can only comfortably fit a pan of around 12 inches in diameter. Because of its straight sides, a 12-inch sauté pan will also have a large, 12-inch-wide cooking surface (about 113 square inches). A skillet, on the other hand, loses at least an inch on each side, making the effective cooking area only 10 inches wide (about 79 square inches). This means that, given a skillet and a sauté pan of equal diameter, the skillet will have 30% less cooking area than the sauté pan. That's not an insignificant amount.
