A basket that's too small lets dough mushroom over the rim. One that's too big lets it slump into a flat pancake. The fix is simpler than most guides make it. As of 2026, the standard recommendation from banneton manufacturers is clear: a 9-inch round basket holds 750g to 1000g of dough, which covers most sourdough recipes built with 500g of flour. Match dough weight to basket size, not the recipe name. ## Quick Answer Use a 9-inch round proofing basket for a standard boule. It holds 750g to 1000g of dough. Here is the quick reference: | Basket Diameter | Dough Weight | Best For | | --- | --- | --- | | 8 inches | 500g–750g | Small loaves, first-time bakers | | 9 inches | 750g–1000g | Standard 500g-flour sourdough | | 10 inches | 1000g–1250g | Large loaves, high hydration | | 11 inches | 1250g–1500g | Big batches, commercial-style baking | Are Bread Proofing Baskets Worth Buying? via America’s Test Kitchen ## Why Basket Volume Beats Basket Diameter for a Boule Diameter alone doesn't tell you much. A 9-inch basket from one brand might be 3 inches deep. Another brand's 9-inch basket might be 4.5 inches deep. Same diameter, twice the room. A basket's job is to support the dough while it proofs. Stiff dough at 65% hydration can handle a shallow basket. Wet, sticky dough at 80% hydration needs walls to lean on. ![banneton depth vs diameter](https://starbreadbakery.org/wp-content/uploads/2026/09/banneton-depth-vs-diameter-mtijlvu1.webp) You also need headroom for the rise. Most bakers fill the basket only 70% to 80% of its depth. A 1000g dough needs roughly 1.5 to 2 liters of basket capacity. ## The 8-Inch Banneton: Best For An 8-inch round basket holds 500g to 750g of dough. It's the right size for a loaf made with 375g of flour. This is the basket for small households, beginners, and anyone who likes baking more often. Small doughs are easier to shape, proof faster, and fit a 4-quart Dutch oven. The trade-off is headroom. Most 8-inch baskets are only 2.5 to 3 inches deep. Keep the hydration moderate, around 70% or lower, and the dough will behave. ## The 9-Inch Banneton: The Home Baker's Standard If you bake one loaf a week, this is the size to buy. A 9-inch round basket handles 750g to 1000g of dough. That range covers a classic sourdough recipe: 500g flour, 375g water, and 100g starter. After mixing, you have about 900g to 975g of dough. It fills the basket without crowding. The finished boule runs 8.5 to 9 inches wide. That fits a standard 5-quart Dutch oven, the most common home baking vessel. ## The 10-Inch Banneton: For Bigger Boules A 10-inch basket takes 1000g to 1250g of dough. That's roughly a recipe with 650g to 700g of flour. This is also the basket for high-hydration doughs. At 80% hydration, a 1000g dough spreads quickly. A 10-inch basket gives it room to rise instead of bulging over the rim. Check the depth before buying. Some 10-inch baskets are shallow trays. Others reach 4.5 inches and hold the dough like a collar. Read the specs carefully. You'll also need a bigger oven. A 1250g boule spreads to 10 inches before baking. That requires a 6-quart Dutch oven or freeform baking on a stone. ## The 11-Inch and Larger: When You Really Need It An 11-inch round banneton holds 1250g to 1500g of dough. It's built for double batches and serious bakers. Most home ovens struggle here. A finished loaf this size spreads past 11 inches. You'll need at least a 7-quart Dutch oven. Depth is non-negotiable at this scale. Look for a basket with 4 inches or more of interior depth. A loaded 1400g dough is heavy, so expect a two-hand tip-out into the baking vessel. ## Quick Comparison Guide: Basket Size vs. Dough Weight vs. Final Loaf Height Save this table for your next bake. ![banneton size comparison guide](https://starbreadbakery.org/wp-content/uploads/2026/09/banneton-size-comparison-guide-mtijlwjt.webp) | Basket Diameter | Dough Weight | Basket Depth | Finished Loaf Width | | --- | --- | --- | --- | | 8 inches | 500g–750g | 2.5–3 inches | 7–8 inches | | 9 inches | 750g–1000g | 3–4 inches | 8.5–9 inches | | 10 inches | 1000g–1250g | 3.5–4.5 inches | 9.5–10 inches | | 11 inches | 1250g–1500g | 4–5 inches | 11 inches | Hydration shifts these numbers. Stiff dough spreads less. Wet dough needs a deeper basket and often a size up. ## Use Cases: Which Basket Size Is Right for You? Match the basket to your baking rhythm. - **8-inch**: solo bakers, beginners, small side loaves - **9-inch**: weekly family loaves, standard sourdough recipes - **10-inch**: high-hydration dough, larger batches, gifts - **11-inch**: holiday baking, double batches, serious enthusiasts If you're not sure, start with the 9-inch. It's the most forgiving and the most versatile. How to Use a Banneton Basket (aka Proofing Basket, Brotform) via Baker Bettie ## What About Linerless Baskets, Colanders, and DIY Alternatives? Rattan isn't the only option. Linerless wood-pulp baskets are lighter, cheaper, and easier to clean. They just don't leave the classic flour spiral on the crust. A colander lined with a floured tea towel works in a pinch. It mimics the shape of a round basket, but the towel can wrinkle and stick to slack dough. Silicone proofing bowls flex and release cleanly. They also trap moisture, which can soften the crust. Try a colander first. If you bake weekly, upgrade to a real banneton. ## Common Mistakes to Avoid: Overproofing, Oversized Baskets, and Sticky Dough The biggest mistake is choosing a basket by diameter alone. Two 9-inch baskets can have very different volumes. Always check the depth. Another common error is using a basket too large for the dough. The loaf spreads, flattens, and loses oven spring. You end up with a pancake instead of a tall boule. ![oversized proofing basket mistake](https://starbreadbakery.org/wp-content/uploads/2026/09/oversized-proofing-basket-mistake-mtijlxbo.webp) Over-dusting is just as frustrating. Too much rice flour creates a thick, gummy layer on the crust. Use a light coat and brush off the excess. Watch the proofing, not the clock. A basket that's too big gives dough room to over-expand and collapse. When the dough feels pillowy and springs back slowly, it's ready to bake. ## Pro Advice: How Hydration and Flour Type Change Your Basket Choice Hydration is the quiet variable nobody talks about. A 70% hydration dough is firm enough to hold its shape in a slightly larger basket. A 75% or 80% dough is more like a thick batter. It needs a smaller, deeper basket for support. Whole wheat and rye doughs are denser. They can't trap as much gas, so they weigh more per cup. Drop one size down when you bake with them. Cold proofing changes the math too. Cold dough holds its shape better. You can get away with a slightly larger basket. Room-temperature dough relaxes and spreads, so size down. ## Real Scenarios: How Bakers Actually Use These Sizes Here's how the numbers play out in practice: - **875g dough** from 500g flour at 75% hydration fits a 9-inch basket - **1080g dough** at 80% hydration needs a 10-inch basket - **1200g dough** for a holiday loaf works in an 11-inch basket with a 7-quart Dutch oven Write down your total dough weight after mixing. After two or three bakes, you'll know exactly which basket your recipes need. ## FAQs ### Can I use an oval proofing basket for a boule? No. Oval baskets shape batards, not round boules. If you want a round loaf, use a round basket. ### Does the basket size change baking time? Yes. Larger loaves need more time to bake through. A 9-inch boule might take 40 minutes covered. An 11-inch loaf could take 50 to 55 minutes. Check that the internal temperature reaches 205°F to 210°F. ### What if my dough is proofing faster than the basket allows? Move the basket into the refrigerator. Cold slows the yeast and gives you more time before baking. ### Should I buy a set or a single basket? Buy a single basket that matches your dough weight. Add a second size only when you bake multiple loaves in one session. ## Final Recommendation: The Best Basket Size for Most Home Bakers Start with a 9-inch round banneton. It covers the widest range of dough weights, fits a standard 5-quart Dutch oven, and matches most sourdough recipes. The 9-inch gives you room to grow. You can bake a smaller 750g loaf without it swimming, or push up to 1000g for a heartier loaf. If you already love baking large, high-hydration loaves, jump to a 10-inch. Just measure your Dutch oven first. Match the basket to your dough weight, not the diameter. That single habit gives you tall, round, beautiful boules every time.
