How to Use the Coffee Brew Ratio Calculator
Great coffee comes down to the ratio between coffee and water. Every brew method has a different ideal ratio because contact time and pressure vary — drip typically uses 1:16, French press 1:15, and a bold method like cold brew goes as low as 1:8. This calculator takes your brew method and target finished volume (ml) and instantly tells you how much coffee and water you need. If you prefer it stronger or weaker, choose Custom Ratio and enter your own water-to-coffee multiplier. Measuring by an exact ratio instead of eyeballing it keeps your cup consistent every time, which makes a real difference for anyone brewing coffee at home.
Standard Ratios by Brew Method
| Brew Method | Standard Ratio (Water:Coffee) |

| Drip / Pour-over | 1:16 |
| French Press | 1:15 |
| Espresso | 1:2 (by output) |
| Cold Brew | 1:8 |
| Moka Pot | 1:10 |
