Coffee Grind Size Chart & Brew Ratios: Complete Guide to Better Extraction
Understanding Coffee Grind Size and Brew Ratios
Grind size and coffee-to-water ratio are two of the biggest factors that shape how coffee tastes. When dialed in correctly, extraction becomes balanced and consistent.
At Five Star Coffee, a small-batch coffee roaster based in Kentucky, we use these same grind size and brew ratio principles every day to produce consistent, high-quality coffee for customers locally in Louisville and across the United States.

Coffee Grind Size Chart Explained
Different grind sizes change how quickly coffee extracts. Coarse grinds extract slower, while fine grinds extract faster. Matching grind size to your brewing method helps improve balance and flavor, as shown in the comparison above.

What grind size should I use for drip coffee?
Medium grind is typically best for drip coffee makers. It allows balanced extraction without over-extracting or producing weak coffee.
What is the best coffee-to-water ratio?
A common starting point is 1:16 (1 gram of coffee to 16 grams of water). This produces a balanced cup for most brewing methods.
Why does my coffee taste bitter?
Bitter coffee is usually caused by over-extraction. This can happen if your grind is too fine, your brew time is too long, or your ratio is too strong.
Why does my coffee taste weak?
Weak coffee is often caused by under-extraction or too much water. Using a stronger ratio or a finer grind can help improve flavor.
Does grind size really matter?
Yes, grind size directly affects extraction speed. Using the wrong grind size for your brewing method can result in unbalanced coffee.
What grind size is best for French press?
Coarse grind works best for French press because it prevents over-extraction and reduces sediment in the cup.
