Bonvoisin Baking Scale 0.1 Gram Accuracy Digital Scale for Kitchen, Candle, Soap and Sourdough Bread Making, with Percentage Weighing Function, Weigh in Grams, Pounds and Ounces (10 lb) Review (2026)

Who this scale is built for

This scale targets bakers who already think in baker's percentages, the method of expressing flour, water, salt and starter as ratios against total flour weight rather than fixed amounts. The percentage weighing function lets a baker enter a target ratio and watch the display count toward it, which removes the mental math of converting a hydration percentage into grams on the fly. It is also marketed for candle and soap making, so the same precision and percentage tools carry over to hobbies that share sourdough's need for accurate small quantity measuring. Casual bakers who only ever follow recipes listed in cups and tablespoons will not get much from the percentage mode, but anyone developing their own sourdough formulas or scaling a recipe up or down will find it directly useful.

Accuracy, capacity and display

The scale reads in increments of 0.1 gram, which is precise enough to weigh salt, yeast, or a small starter inoculation without rounding error stacking up across a recipe. Total capacity is rated at 10 lb, translating to roughly 5 kilograms on the metric side, which covers the vast majority of home sourdough batches including large boules and multi-loaf bakes, though it will not weigh a full stand mixer bowl of dough for a very large batch. Units switch between grams, pounds and ounces, and the scale includes the percentage weighing mode alongside standard weighing. Reviews of similar Bonvoisin scales note a tilted display designed to stay readable even with a large bowl sitting on the platform, which is a practical detail for anyone weighing directly into a mixing bowl rather than a small container.

Living with the scale

Setting up baker's percentages on this scale means placing the mixing bowl on the platform, taring to zero, then adding flour to set the baseline before switching to percentage mode for water, salt and starter. That workflow saves time once it is familiar, though it does take a session or two of reading the manual to learn compared with just tapping tare between each ingredient on a basic scale. Being rated for candle and soap making as well as baking suggests the housing and buttons are built to handle a mix of dry, wet and sometimes sticky ingredients, and the build quality behind that accuracy is rated a step below the fit for the job and value scores, so expect a functional plastic body rather than a premium metal one.

Trade-offs against rival scales

Against general purpose kitchen scales such as the CYBERGIANT 13 lb models, this Bonvoisin scale offers a bit less top end capacity but leans harder into the percentage weighing feature that sourdough bakers specifically want, rather than treating it as a bonus mode. Compared with ultra precision scales rated to 0.01 gram for jewelry or lab work, the 0.1 gram readout on this scale is coarser but still far more precise than most kitchen scales, and it is matched to the range of ingredients a bread baker actually needs to weigh, from a few grams of salt to a few kilograms of dough. Bakers who want the absolute largest capacity for commercial size batches should look at scales rated well above 10 lb instead.

Verdict and who should pick something else

For a home sourdough baker who wants to work in baker's percentages without doing conversion math by hand, this scale's combination of 0.1 gram accuracy and a dedicated percentage mode makes it one of the more purpose built options in its price range. It suits anyone scaling recipes up or down or developing their own formulas more than someone who just follows a fixed recipe in cups. Bakers who regularly mix doughs heavier than about 10 lb, or who want a heavier duty metal housing to match the accuracy, should look at a higher capacity or more industrial scale instead, since this one is sized and built for a home kitchen rather than a bakery.
