Coffee Grind Size Chart: The Only Visual Guide You Need for Every Brew Method
The coffee grind size chart in one line. Espresso needs the finest grind and the shortest contact, cold brew needs the coarsest grind and the longest. Everything else sits between them: Turkish, espresso, moka pot, AeroPress, pour over, South Indian filter, French press, cold brew — in that order, fine to coarse.
The National Coffee Association gives espresso as a "fine (like table salt)" grind with "20–30 seconds" of contact, and pour over as a "medium" grind with "2–4 minutes of contact between coffee and water" at "93 ± 3°C" (NCA, Espresso and NCA, Pour-Over, both read 18 September 2026). The micron figures below are a working reference, not a published standard — see the note under the table.
Why Does Coffee Grind Size Matter?
This coffee grind size chart shows which setting to use for every brew method. Grind size controls how fast water pulls flavour out of coffee.
Fine grinds have more surface area. Water pulls flavour out fast. That suits espresso, where water touches coffee for only 20 to 30 seconds.
Coarse grinds have less surface area, so the pull is slower. That suits a French press, where coffee sits in water for 4 minutes.
The wrong grind for your brew method is the most common reason home coffee tastes bitter, sour or weak.
Think of it like sugar dissolving in water. Powdered sugar dissolves almost instantly. Sugar cubes take minutes. Coffee works the same way - the finer the grind, the faster the extraction. Your job is to match the grind size to the contact time of your brew method.
What Is the Grind Size for Each Brew Method?
This coffee grind size chart covers every common brew method, from ultra-fine Turkish coffee to extra-coarse cold brew. Use it as a starting reference, then adjust by taste.
About the micron column. There is no single published micron standard for coffee grind size. The National Coffee Association describes grind by texture, not by microns. The ranges below are a working reference used across the specialty trade. Treat them as a guide with wide overlap, not as a specification. The texture and contact-time columns are the ones you can check.
| 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 wording) | 20-30 seconds (NCA) |
| Moka Pot | Fine-medium | 300-500 microns | Between table salt and sand | 3-4 minutes |
| AeroPress | Medium | 500-700 microns | Sand | 1-3 minutes |
| Pour Over / Drip | Medium-coarse | 500-900 microns | Medium, coarse sand | 2-4 minutes (NCA) |
| South Indian Filter | Medium-coarse | 700-1000 microns | Coarse sand to fine gravel | 10-15 minutes (drip) |
| French Press | Coarse | 1000-1200 microns | Sea salt or breadcrumbs | 4 minutes |
| Cold Brew | Extra coarse | 1200-1500 microns | Peppercorns or raw sugar | 12-24 hours |
Important: these particle sizes are approximate. Every grinder, bean and brew method varies. Start here, then adjust by taste. Bitter means the grind is too fine, which is over-extraction. Sour means the grind is too coarse, which is under-extraction.
What "grind size numbers" mean. Readers search for grind size in numbers two ways. One is microns, which is the table above. The other is the number on a grinder dial. Those dial numbers are not a standard either — setting 5 on one grinder is not setting 5 on another. The next section maps the dial numbers on our own grinders so you have a starting point.
How Do I Tell What Grind Size I Am Using?
Most home users cannot measure microns. Use texture instead. Rub the grounds between your fingers and match them to a texture you already know.
- Pinch a small amount of ground coffee between your thumb and forefinger
- Rub gently - does it feel like flour (too fine for French press), sand (medium), or salt crystals (coarse)?
- Compare to the chart above - match the texture to your intended brew method
- Adjust your grinder - if it feels too fine, go 2-3 settings coarser. If too coarse, go 2-3 settings finer.
- Brew and taste - the final test is always in the cup. Bitter = go coarser. Sour = go finer. Balanced = you found your setting.

What Grinder Number Do I Set for Each Brew Method?
If you own a grinder with numbered settings, here is how those numbers map to brew methods. This table is for the two InstaCuppa burr grinders sold today: the Automatic Coffee Bean Grinder, 25 Settings (Classic Edition) at Rs 7,199 and the Electric Conical Burr Coffee Grinder, 60 Settings at Rs 7,999. Both were in stock on 18 September 2026. The principle holds for most conical burr grinders: lower numbers are finer, higher numbers are coarser.
| Brew Method | InstaCuppa 25-Setting Grinder | InstaCuppa 60-Setting Grinder |
|---|---|---|
| Espresso | Settings 1-5 | Settings 1-12 |
| Moka Pot | Settings 6-10 | Settings 13-24 |
| AeroPress / Siphon | Settings 11-15 | Settings 25-36 |
| Pour Over / Filter / Drip | Settings 16-20 | Settings 37-48 |
| French Press / Cold Brew | Settings 21-25 | Settings 49-60 |
Pro tip: start in the middle of the range for your brew method. On the 25-setting grinder, start at 3 for espresso and 22 for French press. Make one cup. Taste it. Then move 1 or 2 settings either way until it is right.
What Happens When Grind Size Is Wrong?
The wrong grind size is the most common reason home coffee tastes bad. Here is a fix-it table based on taste alone. You need no equipment.
| Taste Problem | What It Means | Fix |
|---|---|---|
| Bitter, harsh, burnt | Over-extraction - grind is too fine | Go 2-3 settings coarser |
| Sour, thin, weak | Under-extraction - grind is too coarse | Go 2-3 settings finer |
| Simultaneously bitter AND sour | Uneven grind - some particles too fine, others too coarse | Upgrade your grinder (blade grinders cause this) |
| Espresso runs too fast (under 20 seconds) | Grind is too coarse for your portafilter | Go 1-2 settings finer |
| Espresso runs too slow (over 35 seconds) | Grind is too fine or dose is too high | Go 1 setting coarser or reduce dose by 1 gram |
| French press is muddy with sediment | Grind is too fine for French press | Go to the coarsest setting (21-25 on the 25-setting grinder) |

Frequently Asked Questions
What grind size do I need for south Indian filter coffee?
South Indian filter coffee (degree coffee) uses a medium-coarse grind, similar to coarse sand. The traditional brass filter drips slowly over 10-15 minutes, so the grind needs to be coarse enough to not clog the filter but fine enough to extract a strong decoction. On a 25-setting grinder, try settings 16-20. On a 60-setting grinder, try 37-48. Filter coffee grind size is the same medium-coarse band as pour over, roughly 500 to 900 microns.
How fine should I grind for a moka pot?
Moka pot coffee needs a fine-medium grind - finer than drip coffee but coarser than espresso. Think of the texture between table salt and sand. On a 25-setting grinder, start at setting 7-8. If the moka pot sputters and produces very dark, bitter coffee, go 1-2 settings coarser.
Can I use espresso grind in a French press?
No. Espresso grind is far too fine for a French press. The fine particles will pass through the mesh filter and make your coffee muddy with sediment. They will also over-extract during the 4-minute steep, making the coffee extremely bitter. Use a coarse grind (settings 21-25) for French press.
Why does my coffee taste different every morning even with the same setting?
Grind size is not the only thing that moves the taste. Bean freshness, water temperature, dose and even humidity all play a part. On brew temperature there is real evidence: a 2020 study in Scientific Reports brewed drip coffee at 87, 90 and 93°C at a fixed strength, and the panel could not taste the difference. So if your setting has not moved but the cup keeps changing, check the roast date first. Use beans within 2 to 4 weeks of roasting.
Do I need to change grind size when switching between beans?
Often yes. Different beans have different densities and moisture levels. A light roast is denser and harder, requiring a slightly finer grind than a dark roast of the same origin. When switching beans, start at your usual setting and adjust by 1-2 clicks based on taste.
