Coffee Grind Size Chart: From Turkish to Cold Brew

Grind size is the variable most home brewers underestimate. You can nail your coffee to water ratio, use great beans and still get a sour or bitter cup because the grind is wrong for your brewer. This chart gives you a starting point for every common method, plus the signs that tell you which way to adjust.

Coffee grind size chart

Use this chart as a starting map. The texture comparisons are the most practical guide at home; the micron ranges are approximate, rounded from commonly cited charts, and real grinders always produce a spread of particle sizes rather than one exact number.

Grind size	Looks and feels like	Approx. particle size	Best brew methods
Extra fine	Powdered sugar or flour	about 100–200 µm	Turkish coffee (ibrik/cezve)
Fine	Finer than table salt	about 200–400 µm	Espresso, some AeroPress recipes
Medium-fine	Table salt to fine sand	about 400–600 µm	Pour-over cones (V60), AeroPress, moka pot
Medium	Coarse sand	about 600–800 µm	Flat-bottom drip machines, Kalita Wave, siphon
Medium-coarse	Kosher salt	about 800–1,000 µm	Chemex, Clever Dripper, cafe solo
Coarse	Coarse sea salt	about 1,000–1,200 µm	French press, percolator
Extra coarse	Cracked peppercorns	about 1,200–1,600 µm	Cold brew, cowboy coffee

A micron (µm) is one thousandth of a millimeter, so a 1,000 µm particle is about 1 mm across. Few people measure grounds at home, and you don’t need to. The chart is most useful for understanding the order of grind sizes and roughly how far apart they are.

Why grind size matters so much

Brewing is extraction: water dissolving flavor compounds out of ground coffee. Grind size controls how fast that happens in two ways.

1. Surface area. Smaller particles expose more surface to the water, so they extract faster. A fine grind gives up its flavor in seconds; a coarse grind needs minutes.
2. Flow resistance. In any brewer where water passes through a bed of coffee (espresso, pour-over, drip), finer grounds pack more tightly and slow the water down. That lengthens contact time, which increases extraction further.

That’s why the rule of thumb works: short contact time needs a fine grind; long contact time needs a coarse grind. Espresso extracts in under half a minute under pressure, so it needs the finest grind of any common method except Turkish. Cold brew steeps for 12 hours or more, so it needs the coarsest.

Grind size by brew method

Here’s where to start for each method, and how long a typical brew should take at that setting. Brew time is your best clue that the grind is in the right neighborhood.

Espresso: fine

Aim for a texture just finer than table salt that clumps slightly when pinched. A standard shot of 18 g in to about 36 g out (a 1:2 ratio) should take roughly 25–30 seconds. Espresso is so sensitive that tiny grind changes move the shot time by several seconds, which is why espresso grinders have very fine adjustment steps. Our guide to dialing in espresso walks through the process shot by shot.

Turkish coffee: extra fine

Turkish coffee is ground to a true powder, finer than espresso, and simmered with the water rather than filtered. Most home burr grinders can’t go this fine; dedicated Turkish hand mills or pre-ground Turkish coffee are the usual route.

Moka pot: medium-fine to fine

Go a little coarser than espresso. Too fine and the pot can stall or push water through too violently, giving bitter coffee. A texture between table salt and fine sand is a good start.

Pour-over cones (Hario V60 and similar): medium-fine

Start between table salt and fine sand. For a single cup of 15–20 g of coffee, total brew time should land around 2:30–3:30. If water pools and drains slowly past four minutes, go coarser; if it rushes through in under about 2:30, go finer. See the full method in our pour-over guide.

AeroPress: fine to medium-fine

The AeroPress is flexible. Short recipes with a one- to two-minute steep suit a medium-fine grind; espresso-style recipes with a very short steep can go finer. Our AeroPress recipes list a grind for each one.

Drip coffee maker: medium

Most flat-bottom drip baskets do well with a medium grind, about the texture of coarse sand. Cone-shaped baskets often prefer slightly finer. A full pot typically brews in about 4–6 minutes, depending on the machine.

Chemex: medium-coarse

Chemex filters are thick and slow, so a grind that’s perfect for a V60 will often choke a Chemex. Go coarser, around kosher salt, and aim for 4:00–4:30 total (up to 5:00) for a multi-cup brew. The Chemex vs V60 comparison covers why the two need different grinds.

French press: coarse

Coarse sea salt is the target. A four-minute steep at this grind gives a full-bodied cup, and the larger particles are less likely to slip through the metal mesh. If plunging takes real force, your grind is too fine. Our French press guide has the full recipe.

Cold brew: extra coarse

Cold water extracts slowly, so cold brew steeps for 12–18 hours in the fridge (12–16 at room temperature) at an extra-coarse grind, like cracked peppercorns or coarse sea salt. Too fine and the concentrate turns muddy, bitter and hard to filter. Details are in how to make cold brew.

Quick reference: grind, time and ratio

Method	Grind	Typical brew time	Starting ratio
Espresso	Fine	25–30 s	1:2 (dose : yield)
Moka pot	Medium-fine to fine	4–5 min on the stove	about 1:7
AeroPress	Fine to medium-fine	1–2.5 min	1:15
Pour-over cone	Medium-fine	2:30–3:30	1:16
Drip machine	Medium	4–6 min	1:16
Chemex	Medium-coarse	4:00–4:30 (up to 5:00)	1:16
French press	Coarse	4 min	1:15
Cold brew	Extra coarse	12–18 h	1:5 concentrate

How to tell if your grind is wrong

You don’t need a microscope. Your cup and your timer tell you everything.

Signs your grind is too fine (over-extraction)

• Taste: bitter, harsh, ashy or hollow, with a dry, puckering finish.
• Brew time: longer than expected. Pour-over drains slowly; espresso runs past 35 seconds or barely drips.
• Other clues: a French press is hard to plunge, the pour-over filter clogs, or there’s a lot of sludge at the bottom of the cup.

Fix: grind a step or two coarser.

Signs your grind is too coarse (under-extraction)

• Taste: sour, sharp, salty or thin, with flavors that vanish quickly.
• Brew time: shorter than expected. Pour-over water rushes straight through; espresso gushes in under about 22 seconds.
• Other clues: weak, watery coffee even at a strong ratio.

Fix: grind a step or two finer.

How to adjust step by step

1. Brew your usual recipe and note the time and taste.
2. Change only the grind, by one or two steps on your grinder.
3. Keep dose, water amount and temperature exactly the same.
4. Brew again and compare. Repeat until the cup tastes sweet and balanced.

Changing several variables at once makes it impossible to know what helped. Water temperature matters too, but it’s a smaller dial; see our guide to the best water temperature for coffee once your grind is close.

Factors that shift your ideal grind

The chart gives starting points, but a few things push your perfect setting finer or coarser.

• Roast level. Light roasts are denser and harder to extract, so they often need a finer grind than dark roasts for the same method. More on that in light vs dark roast.
• Batch size. A bigger pour-over or Chemex brew has a deeper coffee bed and drains slower, so go slightly coarser as the dose goes up.
• Bean freshness. Very fresh beans release more gas and can brew faster or unevenly; older beans may need a finer grind to taste as lively.
• Your brewer and filter. Thicker paper filters and smaller drain holes slow flow, which calls for a coarser grind.

Why burr grinders matter

Grind size is only half the story. Grind consistency matters just as much.

A blade grinder spins a propeller that smashes beans at random. You get fine dust and big chunks in the same batch. The dust over-extracts and turns bitter while the chunks under-extract and taste sour, so the cup ends up muddy and hard to fix, because changing the grind time just shifts the whole mess.

A burr grinder crushes beans between two burrs set a fixed distance apart. Particles can only leave once they’re small enough to fit through the gap, which gives a much tighter spread of sizes. That consistency is what makes the chart above actually usable: when you move one step finer, the whole batch moves with it.

For most people, the biggest single upgrade after a scale is a burr grinder. A few widely recommended starting points:

• The Baratza Encore ESP is a long-standing entry-level favorite that covers everything from French press to entry-level espresso.
• The Fellow Opus is known for a very wide range in a compact body, useful if you brew espresso and cold brew from the same grinder.
• On a tighter budget, a hand grinder like the Timemore Chestnut C3S is widely regarded as excellent value for pour-over and AeroPress.
