Question: are there different size loaf pans?
Answer: In America, what recipes call a “standard loaf pan” is 8-1/2 x 4-1/2 x 2-1/2 inches. If a store sells only one size of loaf pan, this is probably it. ... But larger loaf pans are not uncommon, either in stores or for recipes. Another common size is a loaf pan measuring 9 x 5 x 2-1/2 inches.
