Find the Right Balance for Better Filter Coffee
A pour over coffee ratio calculator takes the guesswork out of manual brewing. Whether you use a V60, Chemex or Kalita Wave, the relationship between coffee and water shapes the cup far more than most people realise. A lower ratio, such as 1:15, usually tastes stronger, fuller and heavier. A higher ratio, such as 1:17, often produces a lighter, more delicate brew with a tea-like finish.
Simple Maths, Better Brewing
This tool helps you calculate either side of the recipe. If you know how much water you want to brew, it works out the coffee dose. If you’ve weighed your coffee first, it can tell you how much water to use. You can also estimate a total brew target from servings and cup size, which is handy when making coffee for more than one person.
Built for V60, Chemex and Similar Brewers
The pour over coffee ratio calculator is designed for hand-poured filter coffee, with practical presets and space for a custom ratio when you want to fine-tune a recipe. It also includes a simple bloom guide based on roughly twice the coffee dose. If you're adjusting a manual brew ratio for strength, clarity or body, this gives you a calm, reliable place to start.
FAQs
What ratio should I use for pour over coffee?
A good starting point for most hand-poured filter coffee is 1:16. It tends to give a balanced cup with enough body and clarity for everyday brewing. If you want something stronger and a bit heavier, try 1:15. If you prefer a lighter, more delicate cup, 1:17 is often a better fit. The best ratio also depends on your coffee, grinder, brewer and taste, so it’s worth using these as starting points rather than fixed rules.
Is 1ml of water the same as 1g in this calculator?
For practical brewing, yes. In coffee brewing, water in millilitres and grams is usually treated as equivalent because the difference is small enough not to matter in normal home use. That means 300ml of water can be treated as 300g for recipe planning. If you're brewing with scales, grams are still the clearest way to measure because they’re more consistent during pouring.
Does the brewer type change the result automatically?
No. The brewer selector is there to offer a light note, not to silently change your recipe. That’s important because many people already know the ratio they want to brew with. A V60 often sits comfortably between 1:15 and 1:17, while a Chemex can suit slightly higher water volumes for a cleaner cup, but the actual calculation only changes when you choose a different ratio yourself.
