Dough Weight for Yeast Breads: Loaf, Pan & Baker's Percentages (2026)

A standard 9x5-inch loaf pan needs about 925 grams of yeast-bread dough. In baker's percentages that splits into 560g flour (100%), 347g water (62%), 11g salt (2%), and 7g yeast (1.25%) — and those four numbers add up to the 925g total. That 7g is no accident: the median recipe our Yeast Conversion Calculator users run uses 7 g of yeast — about one standard packet — based on 297 real UseCalcPro sessions. Plug your own flour weight into the calculator to scale every other ingredient automatically.

The first time I scaled a sandwich loaf to fill a 9x5 pan, I eyeballed it and ended up with roughly 720 grams of dough — the loaf baked into a squat brick that never reached the rim. The next batch I weighed everything: 560g flour, 347g water, 7g yeast, 11g salt, for 925g total. It crowned a full inch over the pan and sliced clean. The difference was not technique. It was knowing the target dough weight before mixing.

This page is the weight reference, not a full bread course. It gives you the dough weight for yeast breads at every common pan and shape, the baker's percentage formula that generates those weights, and how much yeast each batch needs by type. Every gram here is re-derived from baker's math, and the recipe components always sum to the total dough weight. For the kneading-and-proofing technique, the calculator's own guide covers it.

Dough Weight for Yeast Breads: The Core Number

The baseline for everything below is a standard 9x5x2.75-inch loaf pan, the most common US sandwich-bread size. A lean white loaf that fills it and crowns nicely weighs about 925 grams of total dough. Go lighter than 800g and the loaf stays below the rim; push past 1,050g and the dough overflows and mushrooms. The workable window for a 9x5 pan is roughly 850-1,000g, which is why most sandwich recipes land near 900-950g.

Standard 9x5 loaf = ~925g dough · Workable range = 850-1,000g

That 925g total is built from four ingredients in fixed proportions. The flour is the anchor at 100%, and every other ingredient is expressed as a percentage of that flour weight — the system bakers call baker's percentage. For the standard sandwich loaf: water 62%, salt 2%, yeast 1.25%. Add the percentages (100 + 62 + 2 + 1.25 = 165.25%) and you get a multiplier: total dough = flour weight x 1.6525. The Bread Dough Calculator runs this in reverse, taking a target dough weight and returning each ingredient in grams.

Standard 9x5 Sandwich Loaf (Grams)

The column reconciles exactly: 560 + 347 + 11 + 7 = 925g. The 7g of yeast matches the median that real users enter into our calculator, which is also one standard packet of active dry yeast. That convergence — textbook baker's math landing on the same 7g that 297 home bakers actually use — is a good sign you are in the right ballpark.

Dough Weight by Pan and Shape

The 925g figure is tied to a 9x5 pan. Other pans and freeform shapes need different amounts, scaled by the volume they fill. A smaller 8.5x4.5 pan holds less; a Pullman pain de mie tin holds far more. Rolls and buns are portioned by piece, not by pan, so they are sized individually.

Here are the standard dough weights for the most common yeast-bread formats. These are finished dough weights (flour, water, salt, and yeast combined), the number you weigh on the scale before shaping.

Dough Weight by Pan or Shape

Each per-piece format multiplies cleanly: three 350g baguettes need 1,050g of dough, and a dozen 55g dinner rolls need 660g. Add a small loss factor (about 2%) for dough that sticks to the bowl and bench, so mix slightly more than the table total when you need an exact piece count. For converting batter or dough between round, square, and rectangular pans of any size, the Cake Pan Size Calculator uses the same area-and-volume logic.

How Baker's Percentage Generates Every Weight

Baker's percentage is the engine behind every number on this page. Flour is always 100%, and each other ingredient is a percentage of the flour weight — never of the total dough. This is what lets a recipe scale to any size while keeping the same texture: double the flour and every other ingredient doubles with it.

To go from a target dough weight to actual grams, you reverse the math. Add all the percentages to get the total (165.25% for the standard sandwich loaf), divide the target dough weight by that total to find the flour, then take each ingredient as its percentage of that flour. For a 925g target: 925 / 1.6525 = 560g flour, then water is 560 x 0.62 = 347g, and so on.

Dough Weight by Flour Amount

Every row reconciles to flour x 1.6525: the 700g row is 700 + 434 + 14 + 9 = 1,157g, and the 1,000g row is 1,000 + 620 + 20 + 13 = 1,653g (small rounding on salt and yeast). The 1,000g-flour batch makes enough dough for one 9x5 loaf plus a half-dozen rolls, or two small 8.5x4.5 loaves. Hydration — the water percentage — is where bread styles diverge most, and the Bread Hydration Calculator lets you dial it from a tight 60% sandwich crumb to an open 75% rustic loaf.

Different bread styles use different percentages, which changes both the texture and the total dough weight for the same flour amount. Here is how the common families compare.

Baker's Percentages by Bread Style

The asterisk on milk bread flags that enriched doughs add fat, sugar, milk, and egg on top of the base four ingredients (typically butter 10% and sugar 8%), so the total climbs past the lean formulas even at lower hydration. The lean rustic loaf at 68% hydration totals 560 + 381 + 11 + 6 = 958g, close to the listed 957 after rounding. Whole wheat drinks more water (70%) because bran absorbs moisture, landing near 972g for the same flour.

How Much Yeast Per Loaf — by Type

The 7g of yeast in the standard recipe is active dry yeast, the home-baking default and the median amount real users enter into our calculator. But the gram amount changes with the yeast type, because instant, fresh, and sourdough each have different concentrations. Using the wrong amount is one of the most common scaling errors: swap active dry for the same weight of instant and you over-yeast the dough by a third.

The conversions are fixed ratios. Active dry to instant, multiply by 0.75 (instant is 25% more concentrated). Active dry to fresh cake yeast, multiply by 2.5 (fresh is about 70% water). Active dry to sourdough starter, multiply by 17.5, since starter carries far less active yeast per gram. The Yeast Conversion Calculator handles all four types in one step and returns teaspoons alongside grams.

Yeast Amount for One 9x5 Loaf (560g Flour)

Each figure scales from the 7g active-dry baseline: instant is 7 x 0.75 = 5.25g (rounded to 5.3), fresh is 7 x 2.5 = 17.5g, and sourdough starter is 7 x 17.5 = 122.5g. In teaspoons, active dry runs about 3.1g per teaspoon, so 7g is 2.25 tsp; instant is about 3.0g per teaspoon, so 5.3g is 1.75 tsp. If you switch to sourdough starter, reduce the recipe flour and water by about 61g each, since the 122.5g of 100% hydration starter already contains roughly half flour and half water.

Scaling and Common Adjustments

Most home bakers do not bake a single loaf — they bake a batch. Doubling the standard recipe is straightforward in baker's percentage: 1,120g flour, 694g water, 22g salt, 14g yeast, for 1,850g of dough, enough for two 9x5 loaves. The yeast doubles along with everything else because it is a percentage of flour, not a fixed pinch.

Two adjustments trip people up. First, longer fermentation needs less yeast: if you cold-proof overnight in the fridge, cut the yeast to about 0.6% (3-4g for a single loaf) so the dough does not over-rise before baking. Second, enriched doughs need more yeast, not less — the butter and sugar slow fermentation, so milk bread and brioche typically run 1.5-2% yeast versus the 1.25% of a lean loaf. The Pizza Dough Calculator applies the same percentage logic to pizza, where overnight cold ferments often drop yeast below 0.3%.

The single most useful habit is to decide your target dough weight first, then let the percentages fill in the grams. Whether that target is 925g for one sandwich loaf, 660g for a dozen dinner rolls, or 1,850g for a double batch, the math is identical — only the flour anchor changes.

Frequently Asked Questions

dough weight fo yeast breads

The dough weight for yeast breads depends on the pan: a standard 9x5 loaf needs about 925 grams of dough, a small 8.5x4.5 pan needs about 800 grams, and a large Pullman pan needs about 1,300 grams. That 925g splits into 560g flour, 347g water, 11g salt, and 7g yeast in baker's percentages. Calculate your exact split with the Bread Dough Calculator.

How much dough do I need for a 9x5 loaf pan?

A standard 9x5x2.75-inch loaf pan takes about 925 grams of yeast-bread dough to crown nicely above the rim. The workable range is 850-1,000 grams; below 800g the loaf stays low, and above 1,050g it overflows. Fill the pan about two-thirds with dough before the final proof.

What are baker's percentages for yeast bread?

Baker's percentages set flour at 100% and express every other ingredient as a percentage of that flour weight. A standard sandwich loaf is 62% water, 2% salt, and 1.25% yeast, which totals 165.25% — so total dough weight equals the flour weight times 1.6525. For 560g flour that gives 925g of dough.

How much yeast per loaf of bread?

One 9x5 loaf needs about 7 grams (2.25 teaspoons, or one packet) of active dry yeast, which is 1.25% of a 560g flour batch. That 7g is also the median amount real users enter into our Yeast Conversion Calculator. Use 5.3g if you switch to instant yeast, or 17.5g for fresh cake yeast.

How do I convert dough weight between pan sizes?

Scale by the ratio of pan volumes. An 8.5x4.5 pan holds about 15% less than a 9x5, so it needs about 800g instead of 925g; a 10x5 pan needs about 1,050g. For per-piece formats, multiply the piece weight by the count — twelve 55g dinner rolls need 660g of dough.

How much dough for dinner rolls and hamburger buns?

Dinner rolls are about 55 grams of dough each, so a dozen needs 660 grams. Hamburger buns are larger at about 90 grams each, so a dozen needs 1,080 grams. Add roughly 2% extra dough to cover what sticks to the bowl and bench when you need an exact count.
