There's no single "correct" grind size — it depends entirely on how long the water is in contact with the coffee for your brew method. Pick your method below to get a starting texture and grinder setting.

Grinder dial numbers aren't standardized across brands — use this as a starting point, then adjust based on how your shot or brew tastes and how fast it drains.
A Grinder That Covers the Full Range

Why grind size matters more than almost any other variable
Grind size determines total surface area, and surface area determines how fast water can pull flavor compounds out of the coffee. A method with a short contact time — espresso, at roughly 25-32 seconds — needs a fine grind to extract enough in that window. A method with a long contact time — French press, steeping for several minutes — needs a coarse grind so it doesn't over-extract into bitterness.
Burr grinders produce far more uniform particle sizes than blade grinders, which chop unevenly and produce a mix of dust and chunks in the same batch — that inconsistency is one of the most common causes of muddy-tasting coffee that no amount of dialing in the "average" setting can fully fix.
Dialing in from your starting point
- Sour or weak? Grind finer — the water is moving through (or past) the coffee too quickly to extract enough.
- Bitter or harsh? Grind coarser — the water is in contact too long relative to the particle size, pulling out unpleasant compounds.
- Tastes fine but brew time is off? Adjust grind slightly toward the direction that would fix the timing, and re-taste — time is a symptom, not the goal itself.
Frequently Asked Questions
Grind size controls how much surface area of the coffee is exposed to water, which controls how fast extraction happens.
Too fine for your brew time over-extracts (bitter, harsh); too coarse under-extracts (sour, weak) — matching grind to method and time is the single biggest lever for flavor.
