How Much Coffee Per Cup? 5 Answers

Get the coffee-to-water ratio wrong and your morning cup tastes weak or bitter. We answered the five most common questions about how much coffee to use, with specific amounts for every brewing method.

How Many Grams of Coffee Per Cup?

For a standard 250ml cup, use 15-18 grams of ground coffee. That's roughly 2 level tablespoons, though the exact weight depends on your grind size and brewing method.

Here's a quick reference for common cup sizes:

• Small cup (150ml): 9-11g coffee
• Standard cup (250ml): 15-18g coffee
• Mug (350ml): 21-25g coffee
• Travel mug (500ml): 30-35g coffee

If you're just starting out, 15g per 250ml is a safe baseline. From there, adjust to taste - add a gram if you like it stronger, pull back if it's too intense.

How Many Tablespoons of Coffee Per Cup?

Two level tablespoons gives you about 10-12 grams, which makes a weaker cup. For a standard-strength brew, use 2 heaped tablespoons (around 15-18g).

The problem with tablespoons is consistency. A tablespoon of fine espresso grind packs more densely than a tablespoon of coarse French press grind, so you end up with different amounts of coffee each time. A basic digital kitchen scale - the kind you can pick up for under 10 - removes the guesswork entirely.

If you don't have a scale, level off your spoon with a knife edge and count heaped spoons rather than level ones. It's not perfect, but it's better than eyeballing it.

What's the Best Coffee-to-Water Ratio?

The standard ratio used by specialty coffee professionals is 1:15 to 1:17 (coffee to water by weight). For a 250ml cup, that means 15-17 grams of coffee.

Here's what the different ratios taste like:

• 1:15 - Strong and full-bodied. Good for people who like their coffee bold, or for drinks with milk where the coffee needs to cut through.
• 1:16 - The sweet spot for most people. Balanced flavour, not too strong, not too weak.
• 1:17 - Lighter and more nuanced. Works well for single-origin beans where you want to taste the origin flavours.

Most specialty roasters recommend starting at 1:16 and adjusting from there. It's the ratio that shows up in most brewing guides for a reason - it works.

Does the Ratio Change for Different Brewing Methods?

Yes, and this is where most people get confused. Each brewing method extracts coffee differently, so the ratio and grind size need to match.

• French press - Use a coarser grind at a 1:15 ratio. The metal mesh filters more oils, so you need slightly more coffee to get a full-flavoured cup. Steep for 4 minutes.
• Pour-over (V60, Chemex) - Medium-fine grind at 1:16. The paper filter absorbs oils, producing a cleaner cup. A Chemex with its thicker filters works best at 1:17.
• AeroPress - Flexible. Use a fine grind at 1:12 to 1:15 depending on whether you're brewing standard or inverted. The AeroPress Original is forgiving with ratios.
• Espresso - Much more concentrated. The standard is 18g of coffee in, 36g of liquid out (a 1:2 ratio). This is a different measurement system entirely - you're measuring yield, not water input.
• Cafetiere / French press - Same as French press above. The Bodum Chambord works well at 1:15 with a 4-minute steep.

Should I Weigh My Coffee or Just Use a Scoop?

Weigh with a scale. Every time. A tablespoon of fine espresso grind weighs roughly 7-8 grams. A tablespoon of coarse French press grind weighs about 5-6 grams. That means scooping gives you 20-30% less coffee with a coarser grind, which leads to weak, under-extracted cups.

A basic digital kitchen scale that reads to 0.1g costs under 10 on Amazon UK. It's the single most impactful upgrade you can make to your coffee routine, and it takes up less counter space than a spoon rest.

If you really don't want to weigh, use the "two heaped tablespoons per cup" rule as a rough guide. But once you try weighing for a week, you won't go back. The consistency is worth the tiny extra effort.

Quick Ratio Cheat Sheet

Final Verdict

Start with 15-18 grams of coffee per 250ml cup, use a 1:16 ratio as your baseline, and adjust from there. The exact amount matters less than being consistent - once you find a ratio you like, stick with it and use a scale to hit the same number every morning.

The biggest mistake people make is using too little coffee. If your brew tastes weak or sour, add another gram before blaming the beans. Most "bad coffee" problems come down to under-dosing, not bad beans.
