If you’ve ever tried to work out bread weights for calorie counting or baking, you’ll know that it can be challenging to pin down an exact weight to work out what you need.
Finding the right weight and calorie information can be tricky with various loaf shapes, sizes added ingredients, and not forgetting how thick the slice is.
So, in this article, I’ve categorized various bread slice weights (that I’ve weighed) in charts so you can quickly work out the weights you need.
The simple answer to the question is that a slice of bread can weigh from 25g (0.88oz) for a small thinly sliced loaf up to 80g (2.82oz) for a large thickly sliced loaf, with an average slice weighing around 35-40g (1.23-1.4oz).
Because these weights will depend on various factors, read on to find the correct weights for your favorite bread types.

Bread Slice Weights Infographic
If you’re not sure how thick your slice of bread is, the infographic below shows what each thickness category looks like.
A thin slice is the type you would expect from a small loaf, which is often sold as reduced-calorie bread, such as a danish loaf or Weight Watchers.
An extra thick slice, is more of a doorstop slice of bread, or a thick crust at the end of a loaf.
Weight of Average Slice of bread
If you’re not sure what size your bread is, or the weight of the loaf it came from, an average weight for a typical medium slice of bread, 35-40g (1.23-1.4oz).
This size of slice is typically used as standard sandwich bread, especially if you buy a ready-made pack.
To get an idea of what a slice of bread of this weight looks like, then the image below shows what it looks like on a scale.
Bread Slices per Weight
The tables below will help you work out how many slices of bread you get per certain weight. To keep things simple, I’ve included only thin and thick slice weights, for both small and large loaf sizes.
