| Sourdough | ¾–1 in |
| Thick Artisan Bread | 1–1¼ in |

Bread Loaf Weight After Baking
Bread dough loses water during baking, so the finished loaf weighs less than the dough.
A rough planning estimate is that a loaf can lose around 10–20% of its dough weight during baking, although the exact amount varies.

|---|---|
| 1 lb | 13–14.5 oz |

Common Bread Loaf Size Mistakes
1. Choosing the Wrong Pan
A pan that is too large can produce a short, flat loaf, while a pan that is too small can cause the dough to overflow.
2. Cutting Slices Too Thick
Very thick slices can quickly reduce the number of servings.
3. Ignoring Bread Type
A dense rye loaf and a light white loaf of the same weight may have very different volumes.
4. Overestimating Servings
A loaf’s slice count depends heavily on how it is cut.
5. Storing Bread Incorrectly
Excess moisture, heat, and poor packaging can affect freshness and texture.
Tips for Choosing the Right Bread Loaf Size
Choose a mini loaf: for one person or small portions.
Choose a small loaf: for couples or occasional bread use.
Choose a standard 20–24 oz loaf: for everyday family use.
Choose a large loaf: for large households or frequent sandwiches.
Choose multiple loaves: when serving large parties or events.
