How do I use the chart?
Find the amount of water you plan to brew, read across to the ratio you want, and measure that much ground coffee. A scale is the accurate way. Spoons work, but a heaping tablespoon can be double a level one, so level it off with a knife.
Our own label advice for No. 1 Common Sense is 60 g per litre for drip or French press, which is about 1:16.7 and sits between the 1:16 and 1:17 columns.

Which page has my exact size?
Some sizes have their own page with a weak to strong table and how many pots a 12 oz bag makes:
- 8 oz of water
- a 20 oz tumbler
- 64 oz of water
- a 17 oz French press and a 32 oz French press
- a 3 cup Chemex and a 6 cup Chemex

They are all side by side on the ratio by brewing method chart, and the pour-over ratio cheat sheet adds time. For the spoon math behind this chart, see grams in a tablespoon of coffee and tablespoons in a coffee scoop.
