Slice of bread weight by type

A slice of bread varies in weight with loaf type, thickness, and moisture. Here are some common types and their typical weights.

Type (example)Typical weight
Thin sandwich / light bread sliceabout 20-25 g (0.7-0.9 oz)
Standard white or wheat sliceabout 25-35 g (0.9-1.2 oz)

  • Slice thickness. Thick-cut and Texas-toast slices weigh far more than thin sandwich slices.
  • Loaf style. Dense ryes and sourdoughs are heavier than airy white bread.
  • Crumb density. Tightly packed crumb holds more dough per slice.
  • Moisture. Fresh bread holds more water; stale bread is lighter.
  • Crust amount. End slices include extra crust and weigh a bit more.
  • Added ingredients. Seeds, nuts, or whole grains raise the weight.
