Salt, Levain and Big Doughs: Best Kitchen Scale Sourdough Picks

Sourdough asks two different things of a scale in the same morning. Feeding the starter and mixing the dough means weighing flour and water by the kilogram, often in a heavy bowl or a tall tub. Then the salt goes in, and for a single loaf that is around ten grams, where a gram either way is a real share of the total. Most everyday kitchen scales handle the first job well and the second only roughly.

This guide is for bakers who already know they want to weigh everything and now want a scale built around that routine: fine resolution for salt and levain, enough capacity for a big dough, a tare button that keeps up with one-bowl mixing, and, on a few models, a baker’s percentage mode that does the arithmetic for you.

Quick verdict: which scale to buy for sourdough

None of the seven scales below appears on our main best kitchen scale guide or our baking scale guide; this list is built around the sourdough routine specifically.

Five sourdough scales side by side

Our five standout picks, one for each kind of sourdough baker, with the capacity and smallest step each listing states. All seven scales are reviewed in full below.

Our picks for the best kitchen scale sourdough bakers can use

These seven scales split into three kinds: big-capacity scales for mixing (two with a baker’s percentage mode), a dual-platform scale that does both jobs, and compact 0.1 g scales for salt, levain and starter feeds. We stopped at seven because the other options we found were either unbranded listings with conflicting numbers or near-copies of a scale already here.

Why 0.1 g matters for salt and levain

The case for a finer scale is simple arithmetic. King Arthur Baking’s baker’s percentage reference uses 2 percent salt in its white bread formula. For a loaf made with 500 g of flour, that is 10 g of salt. A 1 g scale can be a gram off either way, and on 10 g that is a tenth of the salt. A 0.1 g scale narrows the error to a few hundredths of the total.

The same goes for small levain builds and starter feeds. If you keep a small starter, say 20 g fed with 20 g of flour and 20 g of water, a 1 g scale leaves little room for error. America’s Test Kitchen makes the same point about yeast and salt in its precision-scale review, and adds that a precision scale works alongside a regular scale rather than replacing it.

Flour and water are another matter. At 350 g of water, a gram either way is far below anything you would notice in the dough, so a 1 g scale is fine for the main mix. That is why the dual-platform scale tops this list, and why a 1 g capacity scale plus a small 0.1 g scale is a sensible pair.

How to choose a kitchen scale for sourdough

Capacity, counting the bowl

The capacity on the box includes whatever container you use. A ceramic mixing bowl can weigh well over a kilogram before any flour goes in, and a big plastic dough tub adds more. For a single loaf, 3 kg is workable with a light bowl; for two loaves or more, look at 5 kg and up. The scales here run from 2 kg to 30 kg.

Resolution where it counts

Decide whether you want one scale with two ranges (the Smart Weigh’s two platforms), one scale with fine steps throughout (the TIMEMORE or the Greater Goods, within their 2 to 3 kg limits), or a 1 g capacity scale plus a small precision scale. All three approaches work; the last is often the most flexible.

Tare and a display you can see

One-bowl mixing means pressing tare after each ingredient, so the button should be easy to hit with floury hands. Check that the display sits clear of a wide bowl: the Bonvoisin tilts its display for this reason, and America’s Test Kitchen’s main scale review puts heavy weight on displays that stay readable under a large bowl.

Auto-off and power

Sourdough steps can be slow. A scale that shuts off after a minute can lose the running total mid-pour. Look for a mains option (the My Weigh), a programmable auto-off, or simply a long default timer. Rechargeable scales (THINKSCALE, TIMEMORE, Bonvoisin) save on batteries; check whether a charging adapter is included.

Baker’s percentage, if you will use it

A percentage mode is a convenience, not a requirement. If you adjust hydration often or scale recipes up and down, it saves time. If you follow one recipe in grams, it adds buttons you will not press.

Cleaning

Flour and wet starter find every gap. A removable tray or pan, a silicone cover or a sealed glass top all make cleanup easier. Fixed platforms with seams around the edge are harder to keep clean.

How we chose these seven sourdough scales

We have not used these scales for this guide. We started from what a working kitchen asks of a scale for bread: enough capacity for the dough and its container, fine resolution for salt and leavening, and a body that survives flour. We then read each product’s Amazon listing for capacity, steps, power, cleaning and warranty, and checked that each one was in stock on Amazon when we wrote this.

For background we used King Arthur Baking’s reference on baker’s percentage and America’s Test Kitchen’s reviews of everyday and precision kitchen scales. We checked the U.S. Consumer Product Safety Commission’s recall database for the brands here; the only kitchen scale recall we found from these brands was the January 2025 Greater Goods recall, which does not list the model above. We left out scales already recommended on our parent and baking guides, scales listed as low stock (including My Weigh’s KD-8000), and unbranded listings whose titles and descriptions gave conflicting capacities or steps.

Sourdough scale questions, answered

What is the best kitchen scale for sourdough bread?

For most bakers, a scale that covers both big and small amounts. The Smart Weigh dual platform does that on one base. A good 1 g scale paired with a 0.1 g precision scale such as the American Weigh SC-2KG works just as well.

Do I really need 0.1 g resolution for sourdough?

Not for flour and water. It helps with salt, small levain builds and any commercial yeast. At 2 percent salt on 500 g of flour you are weighing 10 g, where a 1 g error is a tenth of the salt.

How much capacity does a sourdough scale need?

Add the weight of your bowl or tub to the total dough weight. A single loaf in a light bowl fits under 3 kg; larger batches or heavy bowls call for 5 kg or more.

Is a baker’s percentage function worth it?

It is worth it if you change hydration or batch size often. It shows each ingredient as a share of the flour so you do not have to calculate. If you always bake the same recipe in grams, a plain scale does the job.

Can I use a coffee scale for sourdough?

Yes, within its limits. Coffee scales such as the TIMEMORE and Greater Goods read 0.1 g, which is useful for salt and starter, but their 2 to 3 kg capacity and small platforms suit single loaves and light bowls.

Our pick for the sourdough counter

If you buy one scale for sourdough, make it the Smart Weigh dual platform, so the dough and the salt each get the resolution they need. Once your weighing is sorted, the rest of the kit matters too: a bench scraper for sourdough for dividing and shaping, a silicone baking mat for sourdough for a cleaner bench, and a bread proofing box to keep fermentation on schedule.
