Coffee Grind Size Chart

Match grind to brew method — then learn to check it by feel, because grind names mean nothing across grinders.

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.

Frequently asked

What grind size is best for espresso?
Fine, roughly like fine sand with a few clumps when pinched. But the correct answer is the one that makes your dose and ratio hit 25–30 seconds from first drip. Start finer than you think and work coarser.
What grind for French press?
Coarse, like raw sugar or sea salt. Fine enough to extract in four minutes, coarse enough that the mesh filter keeps most of it out of the cup.
Is finer always better?
No. Finer increases extraction up to a point, then it channels: water finds a path of least resistance and most of the bed stays untouched. Past that point the cup gets more sour and more bitter at the same time.
What grind for cold brew?
Coarse, like raw sugar or coarse peppercorns. Cold water extracts slowly, so a coarse grind over 12–18 hours gives a clean concentrate. Too fine and the result turns muddy and hard to filter.
Does grind size affect caffeine?
Slightly. Finer grounds expose more surface area so extraction is faster and more complete, which can yield marginally more caffeine in the same brew time. Total caffeine is dominated by dose, not grind.
Can I use a blade grinder?
You can, but it produces an unpredictable mix of dust and chunks that no recipe can compensate for. A basic burr grinder is the single biggest upgrade for anyone brewing regularly.
