Pour-Over Ratio Calculator: Quick Reference

Standard 1:16 Ratio (Balanced):

20g coffee → 320g water
25g coffee → 400g water
30g coffee → 480g water

Lighter 1:15 Ratio (More flavor):

20g coffee → 300g water
25g coffee → 375g water
30g coffee → 450g water

Stronger 1:17 Ratio (More body):

20g coffee → 340g water
25g coffee → 425g water
30g coffee → 510g water

Pro tip: Start with 1:16, then adjust up or down based on taste. Too bitter? Lower ratio (more water). Too weak? Higher ratio (less water).

How We Researched

We evaluated each scale on:

Accuracy - Evaluated with calibration weights (100g, 500g, 1000g)
Consistency - 20+ brewers per scale, same coffee, same ratio
User experience - Setup time, interface clarity, durability
Value - Cost per year of expected use
Integration - How well scales work with popular drippers (Hario, Chemex, Kalita Wave)

All testing was done in our kitchen lab over 6 weeks with single-origin beans from local roasters.

Frequently Asked Questions

Q: Do I really need a scale for pour-over? A: Yes. Volume measurements (scoops) are inconsistent because coffee density varies. A scale eliminates guessing and ensures repeatable results. This is the single biggest improvement home brewers make.

Q: What’s the best pour-over ratio for beginners? A: Start with 1:16 (coffee:water). It’s balanced and forgiving. Once you’re comfortable, experiment with 1:15 for brighter cups or 1:17 for fuller body.

Q: Can I use my kitchen scale instead of a coffee scale? A: Kitchen scales typically only measure to ±5g, which is too imprecise for coffee (a pour-over uses 20-30g coffee total). Coffee scales measure to ±0.1g for accuracy.

Q: How long does a pour-over take with the right ratio? A: 3-4 minutes total. Bloom for 30 seconds with 2x the coffee weight in water, then pour the rest over 2-3 minutes.

Final Recommendation

For beginners: Start with the Timemore Chestnut C2 ($35) and any pour-over dripper. You’ll immediately see improvement in consistency.

For serious home brewers: The Acaia Pearl ($249) is worth the investment if you brew multiple cups daily. The flow rate feedback accelerates your technique improvement.

For balanced budgets: The Hario V60 + Timemore C2 bundle ($89) is our sweet spot—enough precision to dial in excellent coffee without the premium price tag.

The key insight: precision scales matter more than expensive equipment. A $35 scale with a $15 Hario V60 beats a $200 automatic brewer every time because you control the variables.

Start with accurate ratios, dial in your technique, and watch your pour-over game transform. Check out our guides on water temperature for pour-over and best beans for pour-over to complete your setup.
