Calculate salt by percentage of food weight for curing, fermenting or seasoning.
Usage Tip
Weigh salt rather than measuring by spoon, as salt crystals vary in density.
What Is Salt Percentage?
Salt percentage expresses how much salt a recipe contains relative to a base ingredient – flour in bread, water in a brine, or vegetables in a ferment. Working in percentages instead of fixed amounts lets you scale any recipe up or down and keep the seasoning identical, which is why serious bakers and fermenters think in percent.
salt weight = base weight × salt % ÷ 100
Baker’s Percentage Explained
In baker’s percentage, flour is always 100% and every other ingredient is expressed as a percentage of the flour weight – including salt. So “2% salt” on 1000 g of flour means 20 g of salt, regardless of how much water or yeast is in the dough. It is the universal language of bread formulas.
| Flour | Salt at 2% | Water at 70% |
|---|---|---|
| 500 g | 10 g | 350 g |
| 1000 g | 20 g | 700 g |
| 1500 g | 30 g | 1050 g |
Salt Percentage for Bread
Most bread sits at 1.8–2.2% salt (baker’s, of flour). Below ~1.5% bread tastes flat and ferments faster; above ~2.5% it tightens the dough, slows yeast, and tastes salty. 2% is the classic all-purpose target.
| Dough (flour) weight | Salt at 2% |
|---|---|
| 500 g | 10 g |
| 1000 g | 20 g |
| 1500 g | 30 g |
| 2000 g | 40 g |
Salt Percentage for Brines
Brines are measured as salt relative to water weight, and run much higher – roughly 3–10%. A quick wet brine for poultry is often 5–8%; a light cure or pickling brine sits lower. Higher salt brines work faster but can over-salt if left too long.
Salt Percentage for Fermentation
Lacto-fermented vegetables use salt as a percentage of the vegetable (plus water) weight, usually 2–2.5%. That range suppresses bad microbes while letting the good lactic bacteria thrive. Too little salt risks mushy or spoiled ferments; too much stalls fermentation.
Common Salt Percentage Ranges
| Application | Typical salt % | Relative to |
|---|---|---|
| Bread dough | 1.8–2.2% | Flour |
| Pizza dough | 2–3% | Flour |
| Brine | 3–10% | Water |
| Sausage | 1.5–2% | Meat |
| Sauerkraut / ferment | 2–2.5% | Vegetables |
Salt Type Comparison
Salt percentage is always measured by weight, so the type does not change the math – but it changes the volume dramatically. A teaspoon of fluffy Diamond Crystal kosher weighs less than half a teaspoon of table salt, which is why measuring salt by volume causes so many errors.
| Salt type | Approx. weight per tsp |
|---|---|
| Table salt | ~6 g |
| Fine sea salt | ~5 g |
| Morton kosher | ~4.8 g |
| Diamond Crystal kosher | ~2.8 g |
Seasoning Balance & Flavour
Salt does more than season: it strengthens gluten, controls fermentation speed, and draws out moisture. In bread, a fraction of a percent shifts both flavour and dough behaviour – which is exactly why the 2.0%-vs-2.2% debate is real. Taste, then adjust in 0.1–0.2% steps.
Common Mistakes
- Measuring salt by volume instead of weight (type-dependent error).
- Confusing baker’s % (of flour) with overall % (of total dough).
- Using brine percentages on dough or vice versa – different base.
- Forgetting to scale salt when scaling a recipe.
- Cutting salt too low in bread, causing slack dough and fast over-proofing.
Frequently Asked Questions
What salt percentage for bread dough?
About 1.8–2.2% of the flour weight (baker’s percentage), with 2% as the classic default.
What is baker’s percentage for salt?
Salt expressed as a percentage of flour weight, where flour is 100%. 2% salt on 1000 g flour is 20 g.
What salt percentage for pizza dough?
Usually 2–3% of flour – a touch higher than sandwich bread for flavour and a tighter dough.
What salt percentage for fermenting vegetables?
Typically 2–2.5% of the vegetable weight – enough to favour good bacteria and keep the ferment crisp.
Does salt type change the percentage?
No – percentage is by weight. But salt type changes the volume a lot, so weigh rather than measure by spoon.
Is baker’s percentage of flour or total weight?
Of flour. Flour is always 100%, and salt, water, and yeast are percentages of that flour weight.
Related Baking Calculators
Baking note: salt percentage is measured by weight; salt types differ in density (kosher vs table), so a gram is a gram but a teaspoon is not. Baker’s percentage assumes flour is 100%. Fermentation, curing, and brining have safety considerations beyond flavour – follow tested recipes for preservation. General guidance, not a guarantee.
