How Much Ground Coffee Per Cup? A Ratio Guide
The right coffee-to-water ratio matters more than the brewer. Here's how much ground coffee to use per cup, and how to scale it up for a full pot.
However good the coffee, the wrong amount of it will always taste wrong - too weak and watery, or too harsh and bitter. Getting "ground coffee for one cup" right, and then scaling that up correctly for a full pot, solves more brewing problems than switching blends ever does.
The Standard Ratio
Most brewing guidelines land somewhere between 1:15 and 1:17, coffee to water by weight - meaning for every gram of ground coffee, use 15 to 17 grams (roughly millilitres) of water. Lower in that range (1:15) gives a stronger cup; higher (1:17) gives a milder one. If you don't have a scale, the simplest working rule most people use is:
About 1-2 tablespoons of ground coffee per 180-200ml (roughly 6-7oz) cup of water.
One tablespoon leans mild, two leans strong - start at 1.5 tablespoons if you're unsure, and adjust from there based on taste.
Scaling Up: Ground Coffee for 10-12 Cups
The ratio doesn't change as you scale up - it just multiplies. For "ground coffee for 10 cups" or "ground coffee for 12 cups," take your per-cup measurement and multiply it directly:
- 10 cups: roughly 15-20 tablespoons (about 100-120g) of ground coffee.
- 12 cups: roughly 18-24 tablespoons (about 120-140g) of ground coffee.
One catch worth knowing: many drip machine manufacturers define a "cup" as 5-6oz rather than a full 8oz mug, so if your pot's markings look generous, check the machine's manual rather than assuming a "cup" is what you'd actually drink from. When in doubt, measure by weight rather than trusting cup markings.
Adjusting for Strength and Brew Method
The 1:15-1:17 range is a starting point, not a rule, and different brew methods and blends pull differently even at the same ratio:
- French press / cafetière: full immersion extracts efficiently, so many people find 1:15 (stronger end) works well without turning bitter, since the coarse grind resists over-extraction.
- Electric drip / pour-over: water passes through once, so 1:16-1:17 is a common sweet spot - go stronger only if your machine or dripper runs water through fast.
- South Indian filter coffee decoction: measured differently again - typically 2-3 tablespoons of finely ground filter coffee powder per cup of the concentrated decoction, then diluted with hot milk, so it isn't directly comparable to a drip or press ratio.
- Personal taste: if a cup at 1:16 tastes weak to you, move to 1:15 rather than assuming the coffee itself is the problem.

Start at roughly 1.5 tablespoons per cup (or a 1:16 ratio by weight), scale that number directly for a bigger pot, and adjust up or down half a tablespoon at a time until it matches your taste.
