Best coffee scales for espresso: slim scales with timers that fit your machine
Slim 0.1g espresso scales sold in the UK, compared on footprint, height, timers and water resistance, with prices checked 3 Oct 2026.
Weighing your espresso as it pours is the single easiest way to make it more consistent. But the best coffee scales for espresso have one job a kitchen scale can’t do: they must fit on your machine’s drip tray, under the portafilter, with a cup on top. This guide is about that fit. We’ve compared five slim scales sold in the UK on their listed size, timer and water resistance. We haven’t tested this in person. Our picks are based on published specs, the retailers’ listings and UK prices checked on 3 Oct 2026. For weighing with any brew method, see our guide to using coffee scales. Read how we compare.
Best coffee scales for espresso: the short answer
Buy the Timemore Mini Espresso Scale for a slim, affordable espresso scale with a listed size. It’s £48.50 at Barista Shop, checked 3 Oct 2026. The listing gives 100 x 114 x 15.8mm, a waterproof, heatproof silicone pad and a 20-hour rechargeable battery.
Who it isn’t for: owners of the smallest machines. At 114mm deep, measure your drip tray first.
Get the Bookoo Themis Mini if space is tight and you want automatic timing. Check price at Bella Barista. It’s the smallest here at a listed 80 x 80 x 15mm, and its automatic mode tares when you place a cup and starts timing when liquid is detected.
Who it isn’t for: budget-led buyers. It costs more than twice the Timemore Mini.
Choose the Rhinowares Stealth if you want a scale built around the drip tray. It’s £79.99 at Barista Shop, checked 3 Oct 2026. Barista Shop says it fits most machine drip trays, with an 86 x 104mm platform and a detachable 85 x 180mm platform.
Who it isn’t for: anyone who wants clear water-resistance details. The listing mentions both IP54 and IP65.
Skip the extras with the Yagua Barista Coffee Scale. It’s £19.00 at Barista Shop, checked 3 Oct 2026, with a small 75 x 64mm platform and a separate timer.
Who it isn’t for: anyone who wants a rechargeable or water-resistant scale. Neither is listed.
What espresso needs from a scale
- 0.1g resolution. Espresso doses are small, so whole grams are too coarse to repeat a recipe. All five scales here are listed at 0.1g.
- Fast response. As espresso pours, you want the number to keep up so you can stop the shot on target. Only the Bookoo Themis Ultra, a bigger sibling of the Mini, gives a figure in its listing (“sub-100ms” at Bella Barista), so we can’t compare response times across these five.
- A timer. Espresso recipes are usually given as dose in, yield out and time. A built-in timer saves juggling your phone.
- Slim and small. The scale has to fit under the portafilter with a cup on top, so height and footprint matter more than capacity.
Who it isn’t for: if you only want to weigh beans before grinding, any 0.1g scale will do, and size doesn’t matter.
Will it fit your machine?
Drip-tray space varies a lot between machines, and it isn’t usually in the headline specs, so get a ruler out before you buy. Measure:
- Width and depth of the drip tray grille. The scale’s footprint should sit flat without hanging over the edge.
- Height from the grille to the bottom of the portafilter spouts. Subtract the scale’s height (about 15–16mm for the Bookoo, Timemore and Eureka) and check your cup still fits.
Compact machines such as the Sage Bambino and De’Longhi Dedica are designed to be narrow, so the smallest scales are the safest bet there. Bigger machines like the Sage Barista Express generally have more room. If a scale is too deep for your tray, some people weigh the shot on the worktop by pulling it into a cup first, but that loses the live reading.
Who it isn’t for: if your cup only just fits under the spouts already, any scale may be too tall. A shorter cup is the cheapest fix.
Auto-timer or manual?
Auto-timers start counting when the scale senses liquid, so you just press the button on the machine. The Bookoo Themis Mini lists this in its automatic mode. The Timemore Mini lists auto-timing on its pour-over setting.
Manual timers need a press when the shot starts. That’s fine once it’s a habit, and it keeps the price down, as on the Yagua.
Who it isn’t for: if you’re happy with a manual press, there’s no need to pay extra for auto modes.
Water and steam
Espresso is messy: drips, steam and the odd overflowing cup. A waterproof or water-resistant scale is worth having if it lives on the drip tray. The Timemore Mini lists a waterproof silicone pad, Bella Barista lists the Themis Mini as waterproof but warns against submerging it or putting it in the dishwasher, and the Rhinowares Stealth is described as designed to withstand steam and water. The Eureka and Yagua listings don’t give water resistance, so wipe them down promptly.
Downsides
- No shared response figures. We can’t rank them on speed.
- Fit isn’t guaranteed. “Fits most drip trays” isn’t a promise for yours.
- Prices change. Check price at Bella Barista for the Bookoo Themis Mini on the day.

What’s the smallest espresso scale here? The Bookoo Themis Mini, listed at 80 x 80 x 15mm at Bella Barista.
Is 0.1g accuracy necessary? For espresso, yes. Doses and yields are small, so 1g steps are too coarse.
