How to Choose a Kitchen Scale (and Why Every Kitchen Needs One)

Short answer: Buy a digital scale that reads in 1 gram steps, holds at least 5 kg (11 lb), has a tare button, switches between grams and ounces, and has a flat platform big enough for your largest mixing bowl. Those five things make a good scale; the rest is convenience. Avoid scales that auto-off in under two minutes and any with a bowl built in.

Why weigh instead of measure

Cups measure volume. Flour, sugar and anything else that can be packed or fluffed gives a different weight every time it is scooped. One cup of flour can weigh 120 g lightly spooned or 160 g packed, a third more. A recipe that works for the person who wrote it then fails for you, and the reason is invisible.

A scale makes recipes repeatable, which is why nearly every serious baking recipe lists grams. It also:

Replaces measuring cups and spoons for most jobs, so fewer things to wash.
Lets you measure straight into the bowl, pressing tare between ingredients.
Makes coffee consistent (a dose in grams, water in grams).
Makes portions honest, if that matters to you.

The five things that matter

1. Increments: 1 g

Look for “1 g” or “0.1 oz” resolution. Scales that count in 2 g or 5 g steps are fine for meat and potatoes but not for baking powder, salt or yeast. For coffee and very small amounts, a separate 0.1 g pocket scale is a good second purchase; it is not a replacement, because those usually top out at 500 g or so.

2. Capacity: 5 kg (11 lb)

A big mixing bowl can weigh a kilogram before anything goes in it. 5 kg leaves room for the bowl and a large batch. Scales rated at 2 or 3 kg run out of room at the wrong moment.

3. Tare

The button that resets the display to zero with something already on the scale. It lets you put a bowl on, zero, add flour, zero, add sugar, and so on, all in one bowl. Every scale has one, but check that it is a real button and not a touch patch that fails with wet fingers.

4. Units

Grams and ounces at a minimum, switched with one press. Milliliters are sometimes offered; they are just grams with a different label (for water) and are not needed. Check that the unit setting is remembered between uses; some cheap scales reset to ounces every time.

5. Platform size and shape

A flat platform of at least 7 by 7 inches (18 by 18 cm) takes a mixing bowl without wobbling. The display should still be visible with a wide bowl on top, which is why scales with the display set forward, or a pull-out display, are easier to live with. Avoid scales with a built-in bowl: they are useless for anything that does not fit the bowl, which is most things.

The things that are nice to have

Auto-off of 3 minutes or more, or none. Cheap scales switch off after a minute of no change, often mid-recipe. This is the most common complaint about kitchen scales.
A flat, sealed surface that wipes clean. Buttons under a smooth membrane are easier to clean than raised buttons.
Common batteries. AAA or a coin cell you can buy anywhere, or USB rechargeable. Avoid odd battery sizes.
A backlit display. Helps on a dim counter.
Low profile. Easier to store in a drawer.
A hanging hook or a stand. Minor, but handy in a small kitchen.

Things you do not need to pay for

Nutrition calculators built into the scale. Slow to use and the food database is never what you are weighing.
App connectivity. A scale that needs a phone to show the weight is worse than one that does not.
Glass platforms. They look nice and crack when dropped. Plastic or steel lasts.
Very high capacity (15 kg and up). These are shipping scales; the increments are coarse.

Checking a scale’s accuracy

New or old, test it once:

Put the scale on a hard, level surface (not a towel or a cloth).
Weigh something of known mass. A US nickel is 5.00 g, so five nickels should read 25 g. A new sealed 1 kg bag of sugar should read within a few grams of 1000.
Weigh the same thing in a different spot on the platform. The reading should not change.
If it reads high or low by more than a gram or two, change the batteries first; low batteries cause drift. Then use the calibration mode if the scale has one (it will be in the manual).

A scale that passes these is accurate enough for anything in a home kitchen.

Using it well

Weigh into the bowl, not into a cup then into the bowl.
Press tare between every ingredient.
Keep it on a hard, level surface; a tilted scale reads low.
Do not leave heavy things sitting on it in the drawer; it stresses the sensor.
Keep the platform dry; water under the platform is the most common way a scale dies.

For coffee, a scale with a timer built in is a small convenience for pour-over, where you time the pour and weigh the water at the same time. For everything else, the plain scale is better value. Our under-$25 gadgets list puts the scale at number one for a reason.

FAQ

Do I really need a kitchen scale?

If you bake, yes. A cup of flour can weigh anywhere from 120 to 160 grams depending on how it is scooped, which is the difference between a good loaf and a brick. For cooking, coffee and portion control it is a convenience rather than a necessity, but a strong one.

How accurate does a kitchen scale need to be?

1 gram increments are right for a general kitchen scale. For coffee, yeast, salt and baking powder, a 0.1 g pocket scale is better; many coffee drinkers own both. Scales that read in 2 or 5 g steps are fine for meat and vegetables but too coarse for baking.

What capacity should I get?

5 kg (11 lb) covers almost everything: a large mixing bowl plus a batch of dough, or a whole chicken. 10 kg scales exist but usually step in 2 g, which is worse for baking. Below 3 kg, you will hit the limit with a heavy bowl.

How do I check if my scale is accurate?

Weigh something of known mass. A US nickel weighs 5.00 g; five nickels should read 25 g. A sealed 500 g bag of flour or sugar should read close to 500 g. If the reading is off by more than a gram or two, use the scale’s calibration mode if it has one, or replace the batteries first, since low batteries cause drift.

Why does my scale turn off while I am using it?

Auto-off, usually at 1 or 2 minutes of no change. It is the most common complaint about cheap scales, especially for pour-over coffee or slow recipes. Look for a scale with auto-off of at least 3 minutes, or one that lets you turn it off.
