Metal muffin pans are available to make several sizes of muffins. Exact pan measurements vary from manufacturer to manufacturer.
Standard Muffin Pans
Available in 12-and 6-cup pans, the standard muffin cup is about 2-3/4 inches in diameter and 1-1/8 inches deep and holds a scant 1/2 cup batter.
Jumbo Muffin Pans
Available in 6-cup pans, the jumbo muffin cups are at least 3 inches in diameter and 1-1/2 inches deep. Each jumbo muffin cup holds approximately 1 cup batter.
Mini Muffin Pans
Available in 12- and 24-cup pans, the mini muffin cup is approximately 1-3/4 inches in diameter and 7/8-inch deep. Each muffin cup holds approximately 2 tablespoons batter.
Muffin Tops (Caps) Pans
Available in 6-cup pans, each muffin top cup is approximately 3 inches in diameter and 1/2-inch deep. Each muffin top cup holds approximately 3 tablespoons batter.
Shiny Aluminum Muffin Pans
Shiny aluminum pans prevent muffins from becoming too dark around the sides.
Dark Nonstick Muffin Pans
Dark nonstick pans keep the muffins from sticking. They tend to brown muffin edges and bottoms quickly. Many nonstick baking pan manufacturers recommend reducing the oven temperature by 25°F.
