Recommended Grind Size for Popular Brewing Methods
Different coffee brewing methods require different grind sizes because they use different combinations of water contact time, pressure, and filtration. Understanding these differences makes it easier to adjust your grinder and improve your coffee brewing results.
Espresso
Espresso generally requires a fine grind. The fine particles provide enough resistance for pressurized water to extract the coffee properly during the short brewing process.
Pour Over
Pour-over brewing commonly uses a medium to medium-fine grind. The ideal setting depends on the brewer, filter, pouring technique, water temperature, and total brewing time.
French Press
French press coffee is commonly prepared with a coarse grind. The larger particles work well with immersion brewing and can make it easier to separate the coffee grounds from the finished drink.
Cold Brew
Cold brew is generally prepared with a coarse grind because coffee grounds remain in contact with water for a long period. A coarse setting can help reduce excessive extraction and make filtering easier.
AeroPress
AeroPress can work with several grind sizes depending on the recipe. Some methods use a medium-fine grind, while longer or inverted recipes may work better with a medium grind.
How to Know If Your Grind Size Is Wrong
Your coffee's flavor can provide useful clues about grind size. If the coffee tastes sour, sharp, thin, or weak, it may be under-extracted and could benefit from a slightly finer grind. If the coffee tastes bitter, harsh, dry, or overly strong, it may be over-extracted and a slightly coarser grind could help.
Make only one small adjustment at a time. Changing the grind size, water temperature, brewing time, and coffee ratio simultaneously makes it difficult to understand which change affected the final flavor.

Coffee Grind Size Calculator FAQs
Find answers to common questions about coffee grind sizes, brewing methods, extraction, and grinder settings.
A Coffee Grind Size Calculator is an online tool that helps you determine a suitable grind size for your chosen brewing method. Instead of guessing whether your coffee should be fine, medium, or coarse, the calculator provides a practical starting recommendation.
Espresso generally uses a fine grind because water passes through the coffee under pressure and the extraction time is relatively short. The exact setting depends on the beans, espresso machine, dose, and extraction time.
French press coffee commonly works best with a coarse grind. The larger coffee particles are suitable for the longer immersion brewing process and can make it easier to separate the grounds.
Pour-over coffee commonly uses a medium to medium-fine grind. The ideal setting depends on the brewer, filter, coffee beans, water temperature, pouring technique, and brewing time.
Yes. Grind size has a major effect on coffee extraction and therefore affects the final taste. A grind that is too fine can contribute to over-extraction and bitterness, while a grind that is too coarse can result in under-extraction and a sour or weak flavor.
Burr grinders generally produce more consistent coffee particles than blade grinders. Consistency can make it easier to control extraction and repeat a brewing recipe.
Cold brew is generally made with a coarse grind because the coffee grounds stay in contact with water for an extended period. The exact setting can vary depending on the coffee-to-water ratio, steeping time, filtration method, and preferred flavor.
Sour or sharp coffee can sometimes indicate under-extraction. Try making the grind slightly finer so the water has more surface area to extract flavor from the coffee. Make a small adjustment and test the result before changing other brewing variables.
