Coffee Ratio Calculator
Dial in the golden ratio for pour over, French press or espresso: enter coffee or water and the brew ratio, and get the other amount instantly.
How to use
- Choose whether you are starting from water or from coffee.
- Enter the amount and the ratio — or pick a preset such as the 1:15 golden ratio.
- Read the matching coffee grams (and tablespoons) or water amount.
Tips
- The 1:15 golden ratio is a great starting point for pour over - adjust stronger or weaker to taste.
- Weigh your coffee in grams for consistency; tablespoons vary with grind size.
- For French press, try 1:12 to 1:14 for a bolder cup.
- Espresso runs much tighter, around 1:2 - do not use filter ratios for espresso.
The Specialty Coffee Association golden ratio is about 1:15 to 1:18 for filter coffee. One level tablespoon of ground coffee is roughly 7 g, but weighing in grams is far more consistent.
