Coffee Grind Size Chart: Every Brew Method + Grinder Numbers
The coffee grind size chart in one line. The shorter the brew, the finer the grind. Espresso is the finest and cold brew is the coarsest.
From fine to coarse, the order runs: Turkish, espresso, moka pot, AeroPress, pour over and drip, South Indian filter, French press, cold brew.
The National Coffee Association gives four easy textures. Espresso is "Fine (like table salt)" and drip is "Medium (like kosher salt)". French press is "Coarse (like rock salt)" and cold brew is "Coarse" (NCA, French Press, read 3 November 2026).
Why Does Coffee Grind Size Matter?
Quick answer: Grind size sets how fast water pulls flavour out of coffee. Match it to how long the water touches the coffee.
This coffee grind size chart shows which grind to use for every brew method. Fine grinds have more surface, so water pulls flavour out fast.
That suits espresso, where water touches the coffee for only 20 to 30 seconds. Coarse grinds pull slowly, which suits a 4-minute French press.
The NCA rule: "the longer the coffee is in contact with water during the brewing process, the coarser the grind should be."
That line comes from the NCA cold brew guide.
Think of sugar in water. Powdered sugar melts at once, but a sugar cube takes minutes.
Evenness matters too. A 2024 study in Scientific Reports found that "the share of fines plays a key role in the espresso extraction flow rate" (Scientific Reports, 2024).
Fines are the dust-like bits under 100 microns, and more of them made the shot run slower.
This is one reason a burr grinder beats a blade grinder for coffee.
What Is the Grind Size for Each Brew Method?
Quick answer: Espresso is fine and moka pot is fine-medium. Pour over and drip are medium, while French press and cold brew are coarse.
This coffee grind size chart covers every common brew method, from Turkish to cold brew. Use it as your start, then adjust by taste.
About the micron column: there is no single published micron standard for grind size. The NCA describes grind by texture, not by microns.
So read the microns as a rough guide with wide overlap. The texture and contact-time columns are the ones you can check at home.
| Brew Method | Grind Size | Particle Size (approx.) | Looks Like | Contact Time |
|---|---|---|---|---|
| Turkish Coffee | Extra fine | Under 100 microns | Flour or talcum powder | Boiled briefly |
| Espresso | Fine | 100-300 microns | Table salt (NCA) | 20-30 seconds (NCA) |
| Moka Pot | Fine-medium | 300-500 microns | Between table salt and sand | A few minutes on the stove |
| AeroPress | Medium | 500-700 microns | Sand | Short steep, then press |
| Pour Over / Drip | Medium (NCA) | 500-900 microns | Kosher salt (NCA) | 2-4 minutes (NCA) |
| South Indian Filter | Medium to medium-coarse | 700-1000 microns | Sand to coarse sand | Slow gravity drip |
| French Press | Coarse (NCA) | 1000-1200 microns | Rock salt (NCA) | About 4 minutes (NCA) |
| Cold Brew | Coarse to extra coarse | 1200-1500 microns | Rock salt or peppercorns | About 12 hours (NCA) |
Important: these sizes are a starting point. Bitter coffee usually means too fine, while sour or weak coffee usually means too coarse.
For exact steps, see our guides on moka pot grind settings and French press grind size.
What "grind size numbers" mean: people search for grind size in numbers two ways. One is microns, as in the table above.
The other is the number on a grinder dial. Those numbers are not a standard, so the section below lists each of our grinders on its own.
How Do I Tell What Grind Size I Am Using?
Quick answer: Rub a pinch between your fingers. Match it to table salt, kosher salt or rock salt, then brew and taste.
Most homes cannot measure microns. Texture works well instead, and you already know these textures from your kitchen.
- Pinch a small amount of ground coffee between your thumb and finger.
- Rub gently. Does it feel like flour, table salt, sand or rock salt?
- Check the chart above and match the texture to your brew method.
- Adjust your grinder by one or two settings at a time.
- Brew and taste. Bitter means go coarser. Sour means go finer.

What Grinder Number Do I Set for Each Brew Method?
Quick answer: It depends on the grinder. On our 60-setting grinder, use 1 to 15 for espresso, 20 to 35 for pour over and 40 to 60 for French press.
Dial numbers change from brand to brand. So this table only uses the starting ranges printed on each InstaCuppa product page, read on 3 November 2026.
| Grinder | Espresso | Moka Pot | Pour Over / Filter | French Press / Cold Brew |
|---|---|---|---|---|
| Electric Conical Burr, 60 Settings | 1-15 | Not listed | 20-35 (pour over, drip) | 40-60 |
| Manual Ceramic Burr, 40 Settings | About 8-12 | 14-20 | 18-24 (pour over), 12-18 (South Indian filter) | 28-35 |
| USB Rechargeable, 38 Settings | 1-15 (fine) | Not listed | 16-25 (start near 20) | 26-38 (French press) |
| Portable Electric Burr V4 | Near 0, the fine end | Near the fine end | The middle | The coarse end |
The Automatic Coffee Bean Grinder, 25 Settings (Classic Edition) covers espresso to French press. Its product page does not print a number for each brew, so find yours with the taste test above.
Pro tip: start in the middle of the range for your brew. Make one cup, taste it, then move one or two settings.
What Happens When Grind Size Is Wrong?
Quick answer: Too fine tastes bitter and too coarse tastes sour or weak. Bitter and sour together usually means an uneven grind.
Here is a fix-it table based on taste alone. You need no tools.
| Taste Problem | What It Means | Fix |
|---|---|---|
| Bitter, harsh, burnt | Over-extraction - grind is too fine | Go 1-2 settings coarser |
| Sour, thin, weak | Under-extraction - grind is too coarse | Go 1-2 settings finer |
| Bitter AND sour at once | Uneven grind - dust and big chunks mixed | Use a burr grinder, not a blade mixie |
| Espresso runs too fast (under 20 seconds) | Grind is too coarse | Go 1-2 settings finer |
| Espresso runs too slow (well over 30 seconds) | Grind is too fine, or the dose is too high | Go 1 setting coarser, or use a little less coffee |
| French press is muddy | Grind is too fine for the mesh filter | Move to the coarse end of your dial |

Which InstaCuppa Grinder Fits Your Brew?
Quick answer: For espresso at home, pick the 60-setting electric grinder. For filter coffee and French press on a budget, the 40-setting manual grinder does the job.
All three are burr grinders with numbered settings. Prices are as listed on our store on 3 November 2026.

Frequently Asked Questions
What grind size do I need for South Indian filter coffee?
Use a medium grind, like sand to coarse sand, so the filter does not clog. Our 40-setting manual grinder suggests settings 12 to 18, and our USB rechargeable grinder suggests 16 to 25.
What grind size is best for cold brew?
Cold brew needs a coarse grind, like rock salt. The National Coffee Association lists cold brew as coarse, with about 12 hours of contact.
How fine should I grind for a moka pot?
Grind a moka pot a little coarser than espresso, between table salt and sand. Our 40-setting manual grinder suggests settings 14 to 20.
Can I use espresso grind in a French press?
No. Fine espresso grounds slip through the mesh and taste bitter after a 4-minute steep, so use a coarse grind like rock salt.
Are grinder numbers the same on every grinder?
No. Each maker numbers its own dial, so start from your grinder's own guide and then adjust by taste.
Why does my coffee taste different every morning with the same setting?
Grind is only one part; beans, dose and water change the taste too. In a 2020 Scientific Reports study, brewing at 87, 90 or 93°C had little impact on taste at the same strength.
