Pro Tips
How To Use This Tool
Coffee ratio is the foundation of recipe design because it determines brew strength before you ever change grind or temperature. This calculator gives you a clean starting point fast.
- 1
Choose your method and desired strength
The suggested ratio shifts depending on whether you want a lighter or heavier cup.
- 2
Enter a water amount or your own custom ratio
The calculator then converts that target into a coffee dose.
- 3
Brew and refine from taste
Once the ratio feels right, fine-tune grind size to improve extraction without rebuilding the whole recipe.
Common Questions
Click a question to expand the answer.
What is a standard coffee ratio for filter brewing?
A common range is about 1:15 to 1:17, but lighter or stronger preferences can sit outside that range.
Does the best ratio change by brew method?
Yes. Immersion, pour over, AeroPress, and cold brew often land in different ratio ranges because they extract at different speeds and strengths.
What ratio is good for stronger coffee without making it muddy?
A slightly tighter ratio like 1:15 or 1:14 can be a reasonable starting point, but clarity still depends on grind quality and extraction.
Should I lock in ratio or water amount first?
Most people start with the beverage size they want, then choose a ratio that matches their preferred strength and calculate the dose from there.
