How to score bread
Short answer: score cold, fully proofed dough just before it goes in the oven, with a razor or lame, in one quick stroke about 6–12 mm (¼–½ inch) deep. Hold the blade low (30–45°) for an ear, straight down (90°) for an even bloom.
Pick a pattern
- Loaf
- Bâtard (oval)
- Blade angle
- 30–45° (low)
- Depth
- 10–12 mm
- Level
- Intermediate
One long, slightly curved cut, a little off-centre along the length of a bâtard. The low angle lifts a flap of crust: the ear.

Step by step
- Proof fully, then chill. Cold dough from the fridge (a common sourdough method) holds its shape and cuts cleanly. Room-temperature dough works too; just move faster.
- Dust the top. A light dusting of rice flour or all-purpose flour makes the pattern stand out against the baked crust.
- Set the angle. Low (30–45°) for an ear; upright (90°) for symmetrical cuts on a round loaf.
- Cut in one stroke. Use the corner of the blade and commit. Sawing or hesitating drags the skin.
- Load and steam at once. Steam keeps the crust soft for the first minutes so the scores can open. A Dutch oven traps the loaf’s own steam.
Why scoring works
In the first 10 minutes or so of baking, a loaf expands quickly: trapped gas expands as it heats and water in the dough turns to steam, while yeast is briefly very active. The crust starts to set at the same time. A score is a deliberate weak point, so the expansion breaks out where you chose instead of tearing along a seam. That’s why under-proofed dough can burst even through a score, and over-proofed dough barely opens at all: there’s too little spring left.
Scoring problems and fixes
| What you see | Likely cause | Try |
|---|---|---|
| Scores barely open | Over-proofed or no steam | Shorter proof; cover the loaf for the first 20 min |
| Loaf bursts at the side | Under-proofed or cut too shallow | Longer proof; one deeper cut |
| Ragged, torn cuts | Dull blade or sticky surface | Fresh razor; chill and dust the dough |
| No ear | Blade too upright | Lower the angle to about 30° |
Wetter doughs spread more and are harder to score cleanly; the hydration calculator shows where your dough sits. Building the loaf itself? Start with the sourdough calculator.
Questions bakers ask
Why do you score bread?
In the first minutes in the oven the loaf expands fast (oven spring) as gas heats and water turns to steam. A score is a planned weak spot: the loaf opens there instead of bursting at a random seam, and you choose the shape of the crust.
How deep should you score bread?
Usually about 6–12 mm (¼–½ inch). Go shallower for decorative leaf or wheat patterns and for slack, high-hydration dough; deeper for a single expansion cut on a well-proofed, tight loaf.
What angle do you hold the blade at?
For an “ear” (the raised flap on a bâtard or baguette) hold the blade low, about 30–45° to the surface, so it undercuts a flap of skin. For an even, symmetrical bloom on a round loaf, cut straight down at about 90°.
What can I use instead of a bread lame?
A clean double-edged razor blade, a very sharp thin knife or a craft knife. Kitchen scissors work for snipped patterns on rolls and wheat-stalk loaves. Avoid serrated knives: they drag and deflate the dough.
Why won’t my scores open?
Common causes: the dough was over-proofed (it has no spring left), the cut was too shallow or hesitant, the oven lacked steam so the crust set too early, or the surface was too wet and the blade dragged. Score cold dough straight from the fridge with one quick, confident stroke.
Do I need to score sandwich loaves baked in a tin?
Not always. A tin supports the sides, so many pan loaves are baked unscored and split naturally along the top. A single lengthwise cut gives a neater, more even rise if you prefer it.
