What is the basic flour to water ratio for bread?

Standard yeasted bread is ~5:3 flour to water by weight (60-65% hydration). Lean bread (no oil/eggs): 65-70% hydration. Enriched (brioche, challah): 50-60% hydration. Pizza/ciabatta: 70-80%.

The full answer

Flour-to-water ratio (expressed as "hydration percentage") is the foundation of all bread baking. The same flour with different water amounts produces dramatically different breads — from tin loaves to ciabatta.

**Standard bread hydration percentages:**

**Basic yeasted bread (sandwich loaf, dinner rolls):** - **60-65% hydration**: 1000g flour + 600-650g water - Tight crumb, easy to handle - Beginner-friendly

**Country/rustic loaves:** - **65-72% hydration**: 1000g flour + 650-720g water - Standard "artisan" bread style - Open crumb developing

**High-hydration artisan:** - **75-80% hydration**: 1000g flour + 750-800g water - Significantly open crumb - Requires stretch-and-fold technique - Examples: Tartine-style, modern bread

**Ciabatta / extreme open-crumb:** - **80-90% hydration**: 1000g flour + 800-900g water - "Liquid dough" — bench scraper required for handling - Maximum open crumb, large irregular holes

**Brioche / enriched dough:** - **50-60% hydration** PLUS butter + eggs - Butter + eggs effectively act as fat-based "liquid" but don't count in hydration % - Lower water because butter doesn't hydrate gluten the same way

**Pizza dough (Neapolitan-style):** - **55-65% hydration** for classic stretchy thin - **70-80%** for New York/Neapolitan high-hydration

**Brioche (special case):** - 50% water + 30% butter + 18% egg + 2% salt - Different ratio system because of additional fats + eggs

**Why hydration matters:** - Water enables gluten formation (gluten network = stretchy bread) - More water = looser dough → easier expansion during proof + bake - More water = more open crumb (CO2 bubbles bigger) - Less water = denser, tighter, sandwich-friendly bread

**Calculating hydration:** - Hydration % = (water grams ÷ flour grams) × 100 - Includes ALL water sources: water + (milk × 0.85) + (eggs × 0.75) - Doesn't include flour from starter (that flour adds to total flour count)

**Salt + yeast in standard bread (baker's percentage):** - 2% salt by flour weight (1000g flour = 20g salt = 2 tsp) - 0.5-2% yeast by flour weight (1000g flour = 5-20g instant yeast) - Sweet spot: 0.5-1% yeast for slow flavorful fermentation; 1.5-2% for quick rise

**Common bread ratios at glance (1000g flour):**

**Basic white sandwich bread:** - 1000g flour - 650g water (65% hydration) - 20g salt (2%) - 8g yeast (0.8%) - 30g oil (3%)

**Rustic Italian/country loaf:** - 1000g flour - 700g water (70%) - 20g salt (2%) - 4g yeast (0.4%) - 8 hour cold ferment

**Sourdough (using starter):** - 1000g flour + 100g flour from starter = 1100g total flour - 700g water + 100g water from starter = 800g total water - 800 ÷ 1100 = ~73% hydration - 20g salt (2%) - 100g active starter (10% of flour weight)

**Tin loaf (sandwich bread):** - 1000g flour - 600g water (60% hydration) - 20g salt + 10g yeast + 50g milk + 30g oil + 15g sugar

**Why protein content matters:**

**High-protein flour (bread flour 12-13%):** - Handles 75-85% hydration - More stretchy gluten = better high-hydration handling - Recommended for artisan bread

**Medium-protein (all-purpose 10-12%):** - Handles 65-75% hydration - Tighter crumb at higher hydration - Most home baking

**Low-protein (00 flour, cake flour 7-10%):** - Best for 50-65% hydration - Doesn't hold high-hydration well - Italian pizza, pastry

**Don't:** - Match volume of water to volume of flour (volume → weight conversion is unreliable) - Increase hydration without adjusting technique - Use cake flour for high-hydration breads (gluten can't support it) - Measure water + flour at different temperatures (affects perceived hydration)

**Cross-reference:** see /pages/what-ratio-of/sourdough-hydration for sourdough-specific hydration + /pages/how-long-does/sourdough-rise for related timing + /pages/how-long-does/brioche-proof for enriched dough.

Most published references (Peter Reinhart "The Bread Baker's Apprentice", Jeffrey Hamelman "Bread", James Beard "Beard on Bread", Ken Forkish "Flour Water Salt Yeast") converge on 60-70% as the standard home-baker baseline.

Time ranges by condition

What changes the time

• Flour protein. Higher protein (12-13%) handles more water; lower (8-10%) needs less
• Climate humidity. Dry climate → flour absorbs less ambient water → effectively lower hydration than spec
• Whole grain content. Whole grains absorb ~5-10% more water; adjust hydration upward when using whole wheat
• Salt + yeast. Salt slows fermentation; yeast accelerates; both have less direct hydration effect
