Best Coffee Scale: 8 Picks for Pour-Over, Espresso and Travel

The best coffee scale for most home brewers is the TIMEMORE Black Mirror Basic 2, because it reads in 0.1 g steps up to 2 kg and adds an auto timer and flow rate. Still, the right pick depends on how you brew: espresso needs a small footprint, pour-over needs range, and travel needs low weight.

In short: get the TIMEMORE Basic 2 for everyday pour-over, the Greater Goods Digital Espresso Scale (750 g) to save money, and the BOOKOO Themis Ultra if you want app tracking and live ratio.

The 8 Best Coffee Scale Picks, Reviewed

First, we ranked these scales by how well each one serves a typical home brewer. So the all-round models come first, and the specialist tools follow. If you also bake, our kitchen scale picks cover larger platforms.

Best Overall

1. TIMEMORE Black Mirror Basic 2

TIMEMORE Black Mirror Basic 2 Coffee Scale with Timer, 2kg/0.1g H…

$55.00

Check Price on Amazon

Best for: home brewers who make pour-over most days and pull the odd espresso shot.

The Black Mirror Basic 2 (sold as Basic 2.0 on the TIMEMORE site) is often the scale people buy once they outgrow a kitchen scale. First, it reads in 0.1 g steps up to 2 kg (about 4.4 lb), so it handles a single cup and a full carafe. In addition, TIMEMORE lists a 0.5 g minimum detection weight, which matters when you pour a slow bloom.

Next, the scale shows a live flow rate test, so you can see how fast you pour in grams per second. Also, the timer can start automatically, which saves a hand during a pour. Meanwhile, the top is acrylic with a waterproof surface, and TIMEMORE includes a silicone pad to protect it. Finally, a 1600 mAh battery gives up to 10 hours of use, per the maker.

• Range: 0.5 g minimum to 2 kg; 0.1 g display steps
• Automatic timer and water flow rate function
• Units: grams and ounces; large backlit LCD with touch buttons
• 1600 mAh rechargeable battery, up to 10 hours; auto-off after 3 minutes
• Waterproof top surface, sealed charging port and silicone pad

Skip it if: you only pull espresso, since you then need a scale that fits under the portafilter.

Best Budget

2. Greater Goods Digital Espresso Scale (750 g)

Greater Goods Digital Espresso Scale with 0.1g Precision, 750g Ca…

$17.99

Check Price on Amazon

Best for: new espresso owners who need 0.1 g readings on a small budget.

Greater Goods sells this small scale for espresso dosing. Specifically, the listing gives 0.1 g precision and a 750 g capacity (about 26.5 oz).

However, 750 g is too low for most pour-over servers with water. So treat it as an espresso and bean-dosing tool. Also, check the listing for the timer and power details, since we could not open the maker’s spec page.

• Capacity: 750 g (about 26.5 oz), per the listing
• Readability: 0.1 g
• Compact platform for espresso dosing

Skip it if: you brew pour-over, where a 2 kg scale makes more sense.

3. BOOKOO Themis Ultra

BOOKOO Themis Ultra Coffee Scale Espresso Scale with Flow Rate Ra…

$99.00

Check Price on Amazon

Best for: brewers who log recipes in an app or want a scale that tracks ratio for them.

Above all, the Themis Ultra is a connected scale built for people who like numbers. First, it offers weight, flow and ratio modes, and flow and ratio can start automatically. As a result, the scale can tell you the live brew ratio while you pour. In addition, it connects over Bluetooth 5.0 to the BOOKOO N app and to apps such as Beanconqueror.

BOOKOO also gives it an IP67 rating, so a spill or a rinse is not a worry. Note that the product page also mentions 3 kg in its copy, but the spec table lists 2,000 g, so plan around 2 kg.

• Range: 0.1 g to 2,000 g (70.55 oz); 0.1 g readability
• Modes: weight, flow (with auto) and ratio (with auto)
• Bluetooth 5.0; BOOKOO N app plus third-party apps
• IP67 water resistance
• 2000 mAh battery, up to 72 hours; USB-C, about 3.5 hours to charge

Skip it if: you just want to weigh beans and press start, so an app adds nothing.

Best for Espresso

4. BOOKOO Themis Mini

BOOKOO Coffee Scale with Storage Bag Esprosse with Timer Mini Dig…

$137.87

Check Price on Amazon

Best for: espresso drinkers who need a scale that fits on a drip tray under the portafilter.

The Themis Mini measures just 8 x 8 cm (about 3.1 x 3.1 in), so it fits on many drip trays. Even so, it reads to 0.1 g up to 1,000 g, which is far more than a double shot needs. In addition, it shows two numbers at once, such as weight and flow.

Next, Auto mode tares and starts the timer for hands-free shots. Moreover, BOOKOO rates the body IPX4 against splashes and builds it from aluminum and tempered glass. Also, it links over Bluetooth to the BOOKOO N app. Finally, BOOKOO specifies a 100 g weight for calibration.

• Range: 0.1 g to 1,000 g; 0.1 g readability
• Modes: timer, flow rate and auto (auto-tare and start)
• Size: 80 x 80 mm footprint; about 140 g
• IPX4 splash rating; aluminum and tempered glass
• Bluetooth with BOOKOO N, Beanconqueror and other apps; 500 mAh battery

Skip it if: you mainly brew large batches of pour-over or cold brew.

Best for Travel

5. Wacaco Exagram Pro

WACACO Exagram Pro Coffee Scale with Timer, Smart Espresso Scale …

Check Price on Amazon

Best for: travelers, campers and office brewers who want a light, rechargeable scale.

To begin with, the Exagram Pro is small enough for a bag at 90 x 95 x 22 mm and 155 g (5.46 oz). However, it does not skimp on features. First, it has normal, pour-over and espresso modes. In espresso mode, it tares and starts timing when brewing begins. Similarly, pour-over mode includes a ratio program and an automatic countdown between pours.

It reads 0.1 g up to 999.9 g, then 1 g steps up to 2 kg. Also, the built-in 700 mAh battery lasts up to 15 hours and charges over USB-C in about 2 hours. Wacaco calls the surface splash-proof but lists no IP rating, so do not rinse it under the tap.

• Range: 0.3 g to 2 kg; 0.1 g to 999.9 g, 1 g above
• Modes: normal, pour-over (with ratio program) and espresso
• Units: g, oz and ml; timer to 9 min 59 s
• 700 mAh battery, up to 15 hours; USB-C, about 2 hours to charge
• Size: 90 x 95 x 22 mm; 155 g

Skip it if: you brew large batches at home every day, because the steps get coarser above 1 kg.

Best Battery Life

6. TIMEMORE Black Mirror Basic 3.0

TIMEMORE Black Mirror Basic 3.0 Coffee Scale, Espresso Scale with…

$65.00

Check Price on Amazon

Best for: brewers who want a live ratio readout without an app and hate frequent charging.

In short, the Basic 3.0 adds a ratio button to the familiar TIMEMORE layout. First, you dose the coffee and tap Ratio. Then the screen shows the live coffee-to-water ratio while you pour. In addition, a slider switches between regular, pour-over and espresso modes, and espresso mode tares and starts timing with the first drop.

Battery life is the other draw. Specifically, TIMEMORE lists up to 24 hours of screen-on time from a 1600 mAh cell, with a USB-C charge in about 3.5 hours. However, read the accuracy table closely. For example, TIMEMORE gives 0.1 g from 0.2 to 500 g, 1 g from 500 to 1,000 g and 3 g from 1,000 to 2,000 g. So it is precise for doses and single cups, but coarse for big batches.

• Load range: 0.2 g to 2,000 g
• Accuracy: 0.1 g (0.2-500 g), 1 g (500-1,000 g), 3 g (1,000-2,000 g), per TIMEMORE
• Regular, pour-over and espresso modes; live flow rate and ratio
• 1600 mAh battery, up to 24 hours; USB-C, about 3.5 hours to charge
• IPX3 splash rating; 140 x 120 x 20 mm; 300 g

Skip it if: you brew full carafes and want fine readings on the water.

Best Design

7. Fellow Tally Pro

Fellow Tally Pro Coffee Scale with Timer, Espresso Scale, Brew As…

Check Price on Amazon

Best for: brewers who want a polished, minimalist scale with a Brew Assist mode.

Fellow is known for its Stagg kettles, and similarly the Tally Pro follows the same clean design. Above all, its main draw, per the listing, is a Brew Assist mode. In addition, it has a timer and is sold as both an espresso and a pour-over scale.

We could not open the Fellow spec page during our research, so check capacity and battery details on the listing.

• Brew Assist mode (per the listing)
• Built-in timer
• Marketed for espresso and pour-over

Skip it if: you want the most features per dollar; the TIMEMORE Basic 2 covers the basics for less.

Best for Batch Brew

8. OXO Good Grips 11 lb Food Scale with Pull-Out Display

OXO Good Grips 11 Pound Stainless Steel Food Scale with Pull-Out …

$59.99

Check Price on Amazon

Best for: people who brew cold brew, large carafes or use one scale for baking too.

Coffee scales top out near 2 kg, but cold brew can call for much more. For example, a 1:8 cold brew with 250 g of coffee needs 2,000 g of water, plus the jar. That is why a kitchen scale like this OXO fits here. In fact, its 11 lb (about 5 kg) capacity leaves plenty of headroom.

Also, the pull-out display stays readable under a wide bowl or pitcher. On the other hand, it is a kitchen scale, so it does not read in 0.1 g steps or include a brew timer. Instead, use it for batch water and beans, and pair it with a smaller scale for espresso.

• Capacity: 11 lb (about 5 kg), per the listing
• Pull-out display for wide containers
• Stainless steel platform

Skip it if: you brew one cup at a time, since you will then want 0.1 g precision.

How We Chose the Best Coffee Scale Picks

First, our picks are research-based. In other words, we did not run hands-on tests. Instead, we compared manufacturer spec pages, help-center articles, retailer listings and patterns in owner feedback. We also checked the Specialty Coffee Association brewing best practices, because a scale only matters if it helps you hit a ratio.

Next, we scored each scale on five points:

• Resolution and range: whether it reads 0.1 g where it counts, and how far that precision extends.
• Brewing tools: auto timer, flow rate, ratio modes and app support.
• Footprint: whether it fits a drip tray, a pour-over server or a travel bag.
• Power and build: battery type, runtime, water resistance and materials.
• Distinct use case: each pick had to serve a different buyer, with no more than two models per brand.

Finally, we dropped unbranded listings and products the maker no longer supports. Also, where we could not confirm a spec, we left it out or said so.

Brew Ratio Math: Why the Best Coffee Scale Reads Grams

In short, a brew ratio compares the weight of coffee to the weight of water. For example, 1:16 means 1 g of coffee for every 16 g of water. Because 1 ml of water weighs very close to 1 g, you can pour by weight and skip the measuring cup.

For a starting point, the SCA lists 55 g of coffee per liter of water, plus or minus 10%. In other words, that works out to about 1:18.2, with a range of roughly 1:16.5 to 1:20.2. Many home brewers, however, like a slightly stronger 1:15 to 1:17.

The math is simple. First, multiply the dose by the ratio number to find the water. Then divide the water by the ratio number to find the dose. For instance, a 12 fl oz mug holds about 355 g of water, and 355 / 16 is about 22 g of coffee.

Espresso ratios

Espresso is different, because you weigh the drink, not the water. A common starting ratio is 1:2, so 18 g of ground coffee yields about 36 g of liquid espresso. So here, a 0.1 g scale really helps. After all, 1 g off on an 18 g dose is a 5.6% error, which you can taste.

Coffee Dose Converter: Grams to Ounces

Many US recipes list ounces, while coffee recipes almost always use grams. So enter a weight in grams to see it in ounces, pounds and kilograms. By default, it shows 20 g, a typical single-cup dose. One ounce is exactly 28.349523125 g, so 0.1 g is only about 0.0035 oz. For more on how small that is, see how much 1 gram is.

Best Coffee Scale Specs, Explained

Resolution versus accuracy

Resolution, or readability, is the smallest step the display shows, such as 0.1 g. Accuracy, by contrast, is how close the reading is to the true weight. A scale can show 0.1 g and still be off by more. So look for brands that publish a calibration method, and check the scale yourself with a known weight.

Capacity and stepped resolution

In general, most coffee scales top out at 1 to 2 kg (2.2 to 4.4 lb). However, some switch to coarser steps as the load grows. For example, the Wacaco Exagram Pro switches to 1 g steps above 1 kg, and TIMEMORE rates the Basic 3.0 at 3 g above 1 kg. Pour-over handles that fine. However, for espresso, make sure the 0.1 g range covers your cup plus the shot.

Timer, flow rate and ratio modes

First, a built-in timer tracks the bloom and total brew time. In addition, an auto timer starts when it senses weight, which frees a hand. Flow rate, shown in grams per second, helps you pour at a steady pace. Finally, ratio modes divide water by dose for you, so you can see 1:16 live.

Footprint and water resistance

Espresso scales need to fit a drip tray, while pour-over scales need room for a server. Also check the water rating. For instance, IPX4 means splash resistance, while IP67 means the scale can survive brief immersion.

How to Weigh a Pour-Over With a Coffee Scale

Overall, these steps work with any of the scales above.

1. Place the scale on a flat, stable counter away from fans and drafts.
2. Set the dripper and server on the scale, add a filter, and rinse it with hot water.
3. Pour out the rinse water, put everything back, and press tare to zero the display.
4. Add your ground coffee, for example 20 g, and tare again.
5. Start the timer and pour about twice the dose in water, here 40 g, to bloom for 30 to 45 seconds.
6. Pour in slow circles until the display shows your target water weight, such as 320 g for 1:16.
7. Note the total brew time, then adjust the grind next time if it ran too fast or too slow.

For water temperature, the SCA lists 200 F, plus or minus 5 F (93.0 C, plus or minus 3 C), at the point of contact with the coffee.

How Accurate Is the Best Coffee Scale? Checking Yours

In practice, most errors come from the setup, such as a tilted counter, a fan or a cable on the platform. So start with a level surface and a fresh tare.

Then test with a known mass. BOOKOO, for example, tells Themis Mini owners to calibrate with a 100 g weight of a stated accuracy class. According to NIST, mass is the amount of matter in an object, while weight is the force of gravity on it. So a kitchen scale actually measures that force and then displays it as mass.

Also, try a repeatability test. Place the same object on the scale five times, and tare between tries. For more ways to measure mass, see our guide to tools used to measure mass.

Coffee Scale Types Compared

Of course, no single scale suits every brew, as this table shows.

If you need to convert ounces in an older recipe, our page on how much an ounce is explains weight and fluid ounces.

Honest Limits of Even the Best Coffee Scale

A scale gives you a repeatable recipe, but it cannot fix stale beans or a poor grinder. Also, 0.1 g readability does not guarantee 0.1 g accuracy, so check yours with a known weight. Likewise, many scales switch to coarser steps above 200 g or 1 kg. Water resistance claims vary too, and splash-proof is not the same as waterproof.

Best Coffee Scale FAQ

What is the best coffee scale for most people?

The TIMEMORE Black Mirror Basic 2 is the best coffee scale for most people. It reads in 0.1 g steps up to 2 kg, and it adds an automatic timer and a flow rate display.

Do I really need a coffee scale?

You do not need one, but it makes coffee far more consistent. A scoop of beans can vary by several grams, while a scale lets you repeat the same dose and ratio every time.

What resolution should the best coffee scale have?

Look for 0.1 g readability. Above all, that level matters for espresso, where 1 g on an 18 g dose is a 5.6% change. For pour-over, 0.1 g on the dose and 1 g on the water is usually enough.

Can I use a kitchen scale for coffee?

Yes, for pour-over and batch brews a 1 g kitchen scale works well enough. However, it is too coarse for espresso dosing, and it usually has no timer, so many people pair it with a small coffee scale.

What is a good coffee to water ratio?

The SCA lists 55 g of coffee per liter of water, about 1:18. However, many home brewers prefer 1:15 to 1:17. For espresso, a 1:2 ratio, such as 18 g in and 36 g out, is a common start.

How do I calibrate a coffee scale?

Place it on a level surface, enter the calibration mode in the manual, and add the reference weight it asks for, often 100 g. Then check that the same weight reads correctly after calibration.

Which is the best coffee scale for espresso?

A small scale with 0.1 g steps and an auto timer works best. For example, the BOOKOO Themis Mini fits many drip trays at 80 x 80 mm and reads up to 1,000 g.

Why does my coffee scale drift?

In most cases, drift comes from drafts, vibration, heat from a hot server or a low battery. Move the scale away from fans, let it settle, and tare again before you pour.

Is a Bluetooth coffee scale worth it?

It is worth it if you log recipes or want a live ratio display, because the app does the math. Otherwise, a simple timer scale gives the same weight readings for less money and less setup.

How long does a rechargeable coffee scale last per charge?

It depends on the model. For example, TIMEMORE lists up to 10 hours for the Basic 2, while BOOKOO lists up to 72 hours for the Themis Ultra.

The Bottom Line on the Best Coffee Scale

For most readers, the TIMEMORE Black Mirror Basic 2 is the best coffee scale to buy. Above all, it pairs 0.1 g steps and a 2 kg range with an auto timer and flow rate, which covers nearly every home brew. Meanwhile, choose a mini scale for espresso, a travel scale for the road and a kitchen scale for batch cold brew.
