One of the most common mistakes when buying a moka pot is choosing the wrong size. Moka pot "cups" aren't what you think, and getting this wrong means disappointing coffee every morning.
I learned this lesson the hard way when I bought my first 12-cup moka pot, thinking it would be perfect for entertaining. What I got was weak, over-extracted coffee that barely filled two regular mugs. The problem? I didn't understand how moka pot sizing actually works.
After years of testing every size available and helping hundreds of customers choose their perfect moka pot, I've created this definitive guide to moka pot sizing. By the end, you'll know exactly which size matches your needs and avoid the most expensive sizing mistakes.
Understanding Moka Pot "Cups"
⚠️ Important Reality Check
Moka pot "cups" are NOT regular coffee cups. They're based on Italian espresso cup sizes (about 2 oz each), which means a "6-cup" moka pot actually makes about 10-12 oz of coffee.
This confusion stems from the Italian tradition of measuring coffee in small espresso servings rather than the large mugs common in North America. Here's what each "cup" actually means:
The Real Numbers:
- 1 Moka Pot "Cup" ≈ 2 oz (60ml)
- 1 Regular Coffee Mug ≈ 8-12 oz (240-350ml)
- Conversion Ratio 4-6 moka cups = 1 regular mug
