Coffee Grind Size Chart
Match grind to brew method — then learn to check it by feel, because grind names mean nothing across grinders.
| Grind | Looks like | Use for | Also works for |
|---|---|---|---|
| Extra fine | powder, clumps when pinched | Espresso (pressurised baskets, turbo shots) | Turkish, espresso |
| Fine | like fine sand, holds a fingerprint | Espresso | Espresso, moka pot |
| Medium-fine | like table salt | AeroPress, moka pot | AeroPress, moka |
| Medium | like coarse sand | V60, pour-over (fast recipes) | V60, Kalita |
| Medium-coarse | like sea salt | Chemex, V60 (large batches) | Chemex, Clever |
| Coarse | like raw sugar | French press, cupping | French press |
| Extra coarse | like peppercorns | Cold brew, percolator | Cold brew |
The grind size chart is a starting point, not an answer
Every grind chart you have seen, including this one, is a rough map. Two grinders set to "medium" can produce particle distributions that differ by a factor of two. A Comandante at 20 clicks and a Niche at 20 are not the same grind, and neither matches a blade grinder at any setting.
Use the chart to get in the right neighbourhood, then use taste and time to finish the job.
How to read grind by feel, not by name
Grind names are useless across grinders, but texture is not. Pinch a sample between your fingers:
- Powder that clumps and stains your skin — espresso territory. Finer than this and you will choke the machine.
- Gritty like fine sand, leaves a residue — still espresso, but the fine end.
- Like table salt, distinct grains you can feel individually — AeroPress and moka pot.
- Like coarse sand, no powder — pour-over.
- Like raw sugar, grains clearly separate — French press.
Why the same coffee needs a different grind tomorrow
Beans degas as they age. A bag opened today and a bag opened two weeks ago need different settings even at the same roast level, because CO₂ escaping from the grounds changes how water moves through the bed. Fresh coffee blooms more, resists water more, and usually wants a slightly coarser grind than the same coffee a week later.
Humidity does it too. On a wet day, static clumps fines together and the shot runs differently at the same setting. This is why keeping a written log of setting and result is worth more than any chart.
Grinder quality matters more than the setting
A cheap burr grinder produces a wide spread of particle sizes: some boulders that never extract, some fines that over-extract immediately. No setting fixes that distribution. If your cups taste simultaneously sour and bitter no matter what you do, the grinder is the limit, not the number on the dial.
Conical burrs generally give more body and a wider sweet spot; flat burrs give more clarity and separation. Both can make excellent coffee. Neither can rescue a bad setting.
