How thick is a piece of toast?

The thickness of a piece of toast typically ranges from about 0.5 to 1 inch, depending on the type of bread used and how it is sliced. Standard sliced bread is usually around 0.5 inches thick before toasting. However, thicker artisanal breads can be sliced up to 1 inch or more. The toasting process may slightly compress the bread, but it generally retains its thickness.
