About Bread Loaf Pan Size Calculator

Pan volume is length times width times height, and a standard sandwich loaf uses roughly 0.36 g of dough per cubic centimetre of pan volume. Loaf pans vary far more than recipes admit, and matching dough weight to pan volume is what decides whether you get a domed loaf or an overflow.

Formulas

Pan volume

volume = length x width x height

Dough weight

recommended dough = pan volume x 0.36 g per cm3
