Coffee Grind Size Chart [With Calculator]: The Complete Guide to Every Brew Method

Ever pull a shot of espresso that tastes like biting into an aspirin, or brew a French press that’s watery and flat no matter how much coffee you use? Chances are, your grind size is off. It’s the most overlooked variable in home brewing, and it’s usually the fastest fix.

Grind size decides how quickly water can pull flavor out of your coffee. Get it wrong, and you’ll either over-extract into bitter, dry territory or under-extract into sour, weak territory. Get it right, and the exact same beans suddenly taste balanced, sweet, and worth getting out of bed for.

That’s what this coffee grind size chart is for. Below, you’ll find a quick-reference table, a breakdown of every grind category from powder-fine to pebble-coarse, specific settings for eight brewing methods, and a troubleshooting table for when your cup just doesn’t taste right. We’ve also built a calculator so you can skip the math and get a straight answer for your brew method.

Coffee Grind Size Calculator

Pick your brewing method and this tool will hand you a grind size recommendation, a micron range, and a texture comparison, so you're not stuck guessing between "medium" and "medium-fine."

Why Grind Size Actually Matters

Grind size isn't just a texture preference. It's the main lever controlling how your coffee tastes.

• Flavor extraction: Water pulls flavor compounds out of coffee grounds through surface contact. Finer grounds have more surface area, so they extract faster. Grind too fine for your method and you'll over-extract into bitterness. Grind too coarse and you'll under-extract into a sour, thin cup.
• Brew time: Every brewing method is built around a specific contact time. Espresso needs 25–30 seconds, so it needs a fine grind that extracts fast. Cold brew steeps for up to a day, so it needs a coarse grind that extracts slowly. Mismatch the two and the coffee never has a chance to balance out.
• Consistency: A grinder that produces wildly uneven particles will extract some grounds too fast and others too slow, at the same time, in the same cup. That's why a good burr grinder matters as much as the grind setting itself.

Coffee Grind Size Chart (Quick Reference)

Most people talk about grind size in three buckets: coarse, medium, and fine. But once you dig into brewing, coffee pros actually work with 7 grind categories, and today's grinders often give you 40 or more individual settings to fine-tune within them.

Since "medium-fine" means something different to everyone, we've paired each category with its approximate size in microns. A micron (µm) is one-millionth of a meter, and it's the only way to describe grind size without relying on comparisons like "sandy" or "salty," which vary depending on who you ask.

Grind Category	Texture Comparison	Approx. Microns	Best For
Extra Fine	Powder or flour	0–200 µm	Turkish coffee
Fine	Table salt	200–400 µm	Espresso, Moka pot
Medium-Fine	Kosher salt	400–600 µm	AeroPress, V60, cone drippers
Medium	Coarse sand	600–800 µm	Drip machines, siphon, Chemex
Medium-Coarse	Rough sand	800–1000 µm	Chemex, Clever Dripper
Coarse	Sea salt	1000–1200 µm	French press, percolator
Extra Coarse	Cracked peppercorns	1200–1400+ µm	Cold brew, cowboy coffee

These ranges aren't exact science. Every grinder distributes particle sizes a little differently, even between two units of the same model, so treat this coffee grind chart as a strong starting point rather than a hard rule. Dial in from there by taste.

The 7 Coffee Grind Sizes, Explained

Collect a coffee grind size chart if you are new to in-home grinding coffee beans. Compare your coffee grounds with the ground chart to get the exact size. Here, we will explain a little to help you understand the different types of coffee grinds.

Extra Fine Grind

This is coffee ground almost to powder, finer than table salt and closer to flour. It's used almost exclusively for Turkish coffee (also called Ibrik coffee), which is simmered with the grounds still in the water rather than filtered out. Because there's no filter to clog and no pump to choke, Turkish coffee can go finer than any other brewing method without causing problems.

Approximate size: 40–220 microns

Fine Grind

Fine grounds feel like table salt between your fingers. This is the grind for methods that force hot water through coffee quickly and under pressure, most notably espresso and the Moka pot. A short brew time only works if the grind is fine enough to extract quickly.

Approximate size: 180–380 microns (espresso); 360–660 microns (Moka pot)

Medium-Fine Grind

Slightly coarser than fine, medium-fine grounds resemble kosher salt or raw sugar. This is the sweet spot for the AeroPress and cone-shaped pour-over brewers like the Hario V60, which need a grind fine enough to extract well in a short brew but coarse enough to avoid clogging the filter.

Approximate size: 320–700 microns, depending on method and recipe

Medium Grind

Medium grounds look like coarse sand, roughly the texture of masonry sand. This is the most commonly pre-packaged grind size in stores, and it works across a surprisingly wide range of brewers, including siphon, drip machines, and some Chemex recipes.

Approximate size: 400–900 microns

Medium-Coarse Grind

Medium-coarse grounds feel like rough beach sand, noticeably bigger than a standard medium grind but still smaller than French press territory. Chemex and the Clever Dripper both perform well here, since their thicker filters need slightly bigger particles to avoid slow, muddy drawdown.

Approximate size: 700–1000 microns

Coarse Grind

Coarse grounds look like sea salt or kosher salt on the larger end. This is the standard for French press and percolator brewing, where the metal mesh filter needs bigger particles to avoid letting too much sediment through. Expect a 3–5 minute brew time at this grind size.

Approximate size: 690–1300 microns

Extra Coarse Grind

The coarsest grind looks like cracked peppercorns or rough, broken bits of coffee bean. It's reserved for methods with very long, low-agitation brew times, like cold brew and cowboy coffee, where a finer grind would badly over-extract over so many hours.

Approximate size: 800–1400+ microns

Grind Size for Every Brewing Method

Here's where the coffee grind size chart gets practical. Below are grind settings, brew times, and tasting notes for eight popular brewing methods, along with settings for five widely-used grinders as a numbered coffee grind size chart you can follow directly.

A quick note on the grinder settings: these numbers assume a standard 40-position dial (like the Baratza Encore) and are meant as a starting point. If you're using a specialty hand grinder like a Comandante, 1Zpresso, Niche Zero, or Fellow Ode, their click scales aren't standardized the same way, and settings can shift between models and even burr generations. For those, use the micron range as your reference and check the manufacturer's chart or a grinder-specific coffee grind chart, to translate it into clicks.

Espresso Coffee Grind Size

Espresso forces hot water through tightly packed, finely ground coffee at high pressure, which is what produces that thick crema and concentrated flavor.

• Grind size: Fine
• Microns: 180–380 µm
• Grind settings: 
  • Baratza Encore: 4-9
  • Baratza Virtuoso Plus: 4-9
  • OXO BREW Conical Burr Grinder: 1-3
  • Capresso Infinity Conical Burr Grinder: 2-4
  • Bodum Bistro: 1-3
• Brew Time: 20-30 seconds
• Temperature: 92–96 °C (198–205 °F)
• Pressure: 9 bars is standard, though some machines allow up to 15
• Tasting notes: Intense, velvety, with a lingering aftertaste

French Press Coffee Grind Size

French press has been a home-brewing staple since the 19th century. It works by steeping coarse grounds directly in hot water, then separating them out with a mesh plunger.

• Grind size: Coarse
• Microns: 690–1300 µm
• Grind settings: 
  • Baratza Encore: 31-36
  • Baratza Virtuoso Plus: 31-36
  • OXO BREW Conical Burr Grinder: 11-13
  • Capresso Infinity Conical Burr Grinder: 12-14
  • Bodum Bistro: 11-13
• Brew Time: 4-5 minutes
• Temperature: 93–96 °C (199–205 °F)
• Notes and Taste: Full-bodied, rich, with a bit of natural sediment

Pour Over Coffee Grind Size

Pour-over covers a family of cone-shaped brewers where you pour hot water over grounds by hand. The grind you need shifts slightly depending on which dripper and filter you're using.

• Grind size: Medium-coarse to Medium-fine

• Microns: 400–930 µm (roughly 400–700 µm for a V60, running a touch coarser for flat-bottom drippers)
• Grind settings: 
  • Baratza Encore: 11-29
  • Baratza Virtuoso Plus: 11-29
  • OXO BREW Conical Burr Grinder: 4-11
  • Capresso Infinity Conical Burr Grinder: 4-12
  • Bodum Bistro: 4-10

• Brew Time: 2:30–4 minutes
• Temperature: 90–96 °C (195–205 °F)
• Notes and Taste: Bright, clean, with more clarity than immersion methods

Chemex Coffee Grind Size

The Chemex uses a noticeably thicker paper filter than most pour-over brewers, which slows the flow of water and calls for a slightly coarser grind to compensate.

• Grind size: Medium-coarse to Medium

• Microns: 700–1000 µm

• Grind settings: 
  • Baratza Encore: 24-29
  • Baratza Virtuoso Plus: 24-29
  • OXO BREW Conical Burr Grinder: 9-11
  • Capresso Infinity Conical Burr Grinder: 10-12
  • Bodum Bistro: 8-10
• Brew Time: 3-5 minutes
• Temperature: 90–96 °C (195–205 °F)
• Notes and Taste: Sparkling, nuanced, and less acidic than a V60

Cold Brew Coffee Grind Size

Cold brew steeps grounds in room-temperature or cold water for many hours instead of using heat to speed extraction. That long contact time means it needs the coarsest grind on this list to avoid turning bitter and muddy.

• Grind size: Extra Coarse

• Microns: 800–1400+ µm

• Grind settings: 
  • Baratza Encore: 31-40
  • Baratza Virtuoso Plus: 31-40
  • OXO BREW Conical Burr Grinder: 11-15
  • Capresso Infinity Conical Burr Grinder: 12-16
  • Bodum Bistro: 11-14
• Brew Time: 12-24 hours
• Temperature: Room temperature or chilled water
• Notes and Taste: Smooth, sweet, and noticeably lower in acidity

AeroPress Coffee Grind Size

The AeroPress is unusually flexible. Depending on your recipe and steep time, you can push it toward an espresso-like grind or a pour-over-like grind, which is part of why it's such a popular travel brewer.

• Grind size: Medium to Fine
• Microns: 320–960 µm, depending on your recipe
• Grind settings: 
  • Baratza Encore: 4-23
  • Baratza Virtuoso Plus: 4-23
  • OXO BREW Conical Burr Grinder: 1-8
  • Capresso Infinity Conical Burr Grinder: 2-9
  • Bodum Bistro: 1-8
• Brew Time: 30 seconds for espresso-style shots; 1–3 minutes for standard recipes
• Temperature: Uses external boiled water
• Notes and Taste: Varies widely with recipe, but generally clean and full-bodied

Drip Coffee Grind Size

Standard drip coffee makers rely on gravity and a steady drip rate, which makes medium-fine the sweet spot: fine enough to extract fully during the brew cycle, coarse enough not to clog the filter basket.

• Grind size: Medium-fine
• Microns: 300–900 µm
• Grind settings: 
  • Baratza Encore: 17-23
  • Baratza Virtuoso Plus: 17-23
  • OXO BREW Conical Burr Grinder: 6-8
  • Capresso Infinity Conical Burr Grinder: 7-9
  • Bodum Bistro: 6-8
• Brew Time: 4-5 minutes
• Temperature: 90–96 °C (195–205 °F)
• Notes and Taste: Balanced, straightforward, easy-drinking

Moka Pot Coffee Grind Size

The stovetop Moka pot uses steam pressure to push water up through the grounds, similar in spirit to espresso but at lower pressure. Bialetti, the company that invented the Moka pot, recommends a grind that feels gritty between your fingers rather than powdery, which lines up with a fine setting just a touch coarser than espresso.

• Grind size: Fine

• Microns: 360–660 µm
• Grind settings: 
  • Baratza Encore: 4-16
  • Baratza Virtuoso Plus: 4-16
  • OXO BREW Conical Burr Grinder: 1-6
  • Capresso Infinity Conical Burr Grinder: 2-6 
  • Bodum Bistro: 1-6
• Brew Time: 5-7 minutes
• Temperature: 100 °C (212 °F) or above
• Pressure: Roughly 1–2 bars of steam pressure
• Notes and Taste: Full-bodied, intense, with a light crema

Taste to Grind: A Quick Troubleshooting Table

If your coffee doesn't taste right, grind size is usually the first thing to check before you touch anything else.

If your coffee tastes...	It's likely...	Try this
Sour, sharp, or salty	Under-extracted	Grind finer, or extend brew time
Bitter, dry, or harsh	Over-extracted	Grind coarser, or shorten brew time
Thin and watery	Under-extracted or under-dosed	Grind slightly finer, or add more coffee
Muddy or heavy	Too many fine particles reaching the cup	Grind slightly coarser, and check your filter

One exception worth knowing: a dark roast can taste bitter even when it's brewed correctly, because the roast itself brings smoky, intense flavors. In that case, don't chase the grind. Chase a lighter roast instead.

How Does Grind Sizes Affect Coffee?

Under the hood, everything above comes down to two failure modes: under-extraction and over-extraction.

Under-extraction happens when:

• The grind is too coarse for the method
• The water is too cool
• The brew time is too short

The result is a cup that tastes sour, salty, or hollow, because the water didn't have enough time or surface area to pull out the sweeter, more balanced compounds.

Over-extraction happens when:

• The grind is too fine for the method
• The water is too hot
• The brew time runs too long

The result is bitterness, because the water kept pulling flavor out of the grounds well past the point where it was still pleasant.

There's no universal "correct" grind size across all coffee. A grind that works beautifully for a French press will completely clog an espresso machine, and a fine espresso grind will turn a French press into sludge. Match the grind to the method first, then fine-tune from there.

A note on dose: grind size and dose work together. The National Coffee Association recommends a "golden ratio" of roughly 1–2 tablespoons of ground coffee for every 6 ounces of water as a starting point for drip-style brewing, which works out to about 9–11 grams per 6 ounces of water. Espresso runs on a totally different ratio, typically around 1:2 (grams of coffee to grams of liquid out), since it's a concentrated shot rather than a full cup.

Coffee Grinder Settings: How to Read the Dial

Every grinder handles its scale a little differently, but the underlying logic is the same across brands.

• Burr grinders vs. blade grinders: A burr grinder crushes beans between two surfaces to produce consistent particle sizes. A blade grinder chops beans with a spinning blade, producing an uneven mix of dust and chunks in the same batch. That inconsistency causes over-extraction and under-extraction to happen at once, which is why a quality burr grinder is worth the investment if you're serious about your coffee.
• Reading your grinder's coffee grinder size chart: Most home grinders (like the Baratza Encore) use a numbered dial from roughly 1 to 40, with lower numbers producing finer grounds and higher numbers producing coarser ones. Specialty hand grinders instead use audible clicks from a "zero point," where the number of clicks (not a printed number) tells you the setting.
• Dialing in: Start with the manufacturer's recommended setting for your brew method, then adjust one step at a time. Espresso is sensitive to tiny changes, sometimes a single click, while French press and cold brew tolerate much bigger adjustments without much taste difference.

For cupping and professional quality control, the Specialty Coffee Association recommends grinding so that 70–75% of particles pass through a U.S. Standard 20-mesh sieve, which works out to roughly 850 microns. It's a good illustration of just how precisely grind size can be measured once you leave home-brewing behind.

Grinders And Grinding

Coffee grinders grind coffee beans into different sizes to make coffee drinks. Check out some basic information about coffee grinders.

Types Of Grinders

Coffee grinders break down along two lines: how they're powered, and how they cut the beans.

By power source:

• Manual grinders run on your own arm strength, using a hand crank
• Electric grinders do the work for you at the push of a button

By mechanism:

• Blade grinders chop beans unevenly and are best avoided for anything beyond basic drip coffee
• Burr grinders crush beans between two surfaces for a far more consistent grind

Burr grinders come in two main styles. Flat burr grinders use two parallel, ring-shaped burrs and tend to run a little faster, though they waste slightly more coffee at the edges. Conical burr grinders nest one cone-shaped burr inside another and generally retain less coffee, making them a popular choice for home use.

How to Use a Coffee Grinder

The basics stay the same across most grinders:

1. Let freshly roasted beans cool before grinding
2. Add a modest amount of beans to the hopper and close the lid
3. Set the dial or clicks to match your brewing method
4. Grind, then brew right away for the best flavor
5. Store any leftover grounds in an airtight container
6. Clean the grinder after use

How To Clean Coffee Grinders

Stale oil buildup inside a grinder will taint every batch that follows, so regular cleaning matters. You'll want a soft brush, a toothpick for tight corners, and grinder-cleaning pellets for a deeper clean.

• Empty out any leftover grounds first
• Brush away loose grounds from the burrs and chute
• Use a toothpick to clear narrow gaps a brush can't reach
• For a deep clean, disassemble the grinder, wipe every part down, let everything dry fully, and reassemble

Aim for a light brushing after most uses and a deeper clean once or twice a month.

If your grinder breaks or you're brewing while traveling, a few household tools can step in:

• Mortar and pestle
• Blender
• Food processor
• Rolling pin (crush beans in a sealed bag)
• Hammer (same idea, more force)
• Sharp knife, chopping in small batches

None of these will match a burr grinder's consistency, but they'll get you a cup of coffee in a pinch.
