Grinder spec sheets lead with burr size, motor wattage and the number of settings. Some of those numbers help you choose, and some don't. This guide sorts them out for espresso and filter brewing.
What matters for espresso
- Small adjustment steps at the fine end. Espresso shot time responds strongly to grind. CoffeeGeek measured about 5 seconds of shot-time change per espresso click on the Encore ESP (CoffeeGeek). Stepless dials, or clicks of around 8–12.5 µm on hand grinders like the J-Ultra and X-Ultra, give finer control.
- A stated espresso range. Some grinders say plainly that they are not for espresso: Fellow says the Ode Gen 2 is for brewed coffee only, and the plain Encore's retailer listing points espresso buyers elsewhere.
- Dosing into a portafilter. Cradles, dosing cups sized for 54 and 58 mm, or a funnel.
What matters for filter
- Even steps across the coarse range, with enough room to go from pour-over to French press.
- Fewer fines at coarse settings. CoffeeGeek found some conical grinders produced more fines at press-pot settings (Smart Grinder Pro, Encore ESP).
- Batch size. Hand grinders with 35–40 g capacity (the K-Ultra) handle multi-cup brews.
Numbers that do not predict the cup
- Burr diameter alone. Bigger burrs can grind faster, but diameter does not establish particle distribution or taste.
- Motor wattage. It describes the motor, not the grind.
- "Anti-static." A design claim until someone measures it.
- Setting counts. 60 settings spread evenly can give coarser espresso control than 20 closely spaced ones.

Recommendation
If espresso is in your plans at all, choose a grinder with a stated espresso range and small steps at the fine end. Every grinder is a compromise between espresso and filter; the question is which side you favor.
