Grind Size for Drip Coffee (2026): Easy Guide

Quick answer: start medium

Use medium as your first grind size for drip coffee maker brewing. The National Coffee Association’s drip guide recommends starting there and adjusting as needed. Treat the sand comparison as a rough visual cue, not a measurement: the cup gets the final vote.

What you'll need before adjusting

Use the brewer and filter you plan to keep using, plus a way to measure coffee and water. Basket shape, water flow, and brewer design can change the starting point. Check your machine’s manual first; our best drip coffee makers under $100 guide compares suitable machines if you're replacing yours.

• One bag of beans: avoid swapping roasts halfway through.
• An adjustable grinder: preferably a burr model, which crushes beans between grinding surfaces.
• A kitchen scale: weigh the grounds rather than guessing by scoop volume.
• A correctly fitted filter: use the size and style your brewer specifies.

Fellow’s grind chart places drip around medium and cone pour-over finer. A cone-shaped automatic basket is not a reason to jump straight to a hand-poured cone recipe.

How to find your setting

Make a measured batch at medium, taste it, and change only the grind for the next batch. Keep the same beans, filter, water amount, coffee weight, and brewer mode. That routine lets you tell whether the new setting helped, rather than guessing which change made the difference.

1. Choose medium on your own grinder

Start with your grinder maker’s drip or filter recommendation. Spread a pinch on a light-coloured plate: you're looking for distinct grains, not powder. Write down the setting before brewing. Do not assume the middle dial number means medium; grinders cover different ranges.

Roasty’s Encore settings guide describes a broad drip range. Those numbers belong to that model, not every grinder with a numbered dial.

2. Brew and name the problem

Brew your usual batch and let a sip cool enough to taste comfortably. Note whether it feels thin and sharply sour, harsh and bitter, or pleasantly balanced. Extraction means how much flavour the water pulls from the grounds; the NCA explains that grind affects that process.

3. Move a little, then compare

Try a small move finer for sour, thin coffee, or coarser for harsh bitterness. Use the smallest practical change in your grinder’s filter range. Follow its instructions for moving the dial, then brew again. If the cup gets worse, return to your previous setting instead of continuing blindly.

Why grind consistency helps

Choose a burr grinder when you want small adjustments you can repeat. Coffee Review’s “Minding the Grinds” explains that particle-size spread and brewing method both matter. For researched upgrade options, see our best burr coffee grinders under $200.

Common mistakes to avoid

Do not chase strength by making huge grind changes. A watery cup and a sour cup are not always the same problem. First check that you used your intended coffee and water amounts. If those were wrong, correct the recipe before blaming the grinder or buying new equipment.

• Using espresso-fine grounds: very fine grounds can slow brewing and make coffee bitter.
• Judging coffee left on the warming plate: taste a freshly brewed cup when comparing settings.
• Changing batch size mid-adjustment: keep your usual amount until you've found a setting you like.

Fix weak, bitter, or muddy coffee

Match the next adjustment to the symptom, not just the colour of the coffee. These are starting fixes, not diagnoses: the NCA connects overly coarse grounds with under-extraction and overly fine grounds with bitterness. If a small grind change does not help, check the recipe and brewer before going further.

Muddy cup or overflowing basket

Check that the filter is not torn, folded, or the wrong size, and that the basket is not overfilled. Fine grounds can slow flow, so try coarser if draining has slowed. Sediment alone does not prove the grind is wrong, especially if you changed filter type.
