If you’re brewing a full 12-cup pot of coffee and want it to taste just right—not too weak, not too bitter—you’re probably wondering how many tablespoons of coffee you actually need. The short answer is: you should use about 24 tablespoons of ground coffee for 12 cups, assuming you’re using the standard measurement of one tablespoon per 6-ounce cup.
But wait—coffee measurements can get confusing. Depending on how strong you like your coffee, what kind of coffee you’re using, and how big your “cup” really is, the number can shift slightly. Let’s break it down and help you brew the perfect pot.
Understanding the Standard Coffee Cup Size
First off, when coffee makers say “12 cups,” they don’t mean 12 full mugs. A “coffee cup” in the coffee world is typically 5 to 6 ounces, not 8 ounces like a regular measuring cup. That means a 12-cup coffee maker actually brews about 60 to 72 ounces of coffee in total.
If you’re using a standard drip coffee maker, assume each “cup” is around 6 ounces. So, for 12 cups, you’re looking at 72 ounces of brewed coffee.
General Coffee-to-Water Ratio
Most coffee experts recommend a 1:15 to 1:18 coffee-to-water ratio by weight. But measuring grams every morning isn’t everyone’s idea of a good time. That’s why many home brewers stick to tablespoons as a simple and reliable way to portion coffee.
Here’s a quick guideline:
- 1 tablespoon of ground coffee per 6 ounces of water (for mild strength)
- 1.5 to 2 tablespoons per 6 ounces (for medium to strong strength)
So, for 12 cups:
- Mild brew: 12 tablespoons
- Standard strength: 18 tablespoons
- Bold brew: 24 tablespoons
For most people who want a balanced, flavorful cup, 18 to 24 tablespoons (or around 1 to 1.5 tablespoons per cup) works best.
Scoop vs. Tablespoon
It’s also worth noting that many coffee scoops are designed to hold 2 tablespoons of ground coffee. So if you’re using one of those standard scoops, you’d need:
- 9 scoops for a standard strength 12-cup brew (18 tablespoons)
- 12 scoops for a stronger brew (24 tablespoons)
Make sure to check your scoop size—some may only hold 1 tablespoon.
Adjusting for Your Taste
Here’s where personal preference comes in. If you like your coffee on the lighter side, stick closer to 1 tablespoon per cup. If you enjoy a stronger flavor, go for 1.5 or even 2 tablespoons per cup.
When I brew a 12-cup pot for guests, I usually use 20 tablespoons, which gives a rich, not-too-strong flavor that most people seem to enjoy. But if it’s just for me, I bump it up to 22–24 tablespoons, especially if I’m using a darker roast.
Don’t Forget Grind Size and Bean Type
Not all coffee grounds are created equal. If you’re using pre-ground coffee, make sure it’s the right grind for your machine. A medium grind is ideal for drip coffee makers. Too fine and it can clog the filter; too coarse and it can make your coffee taste weak.
Also, keep in mind that dark roast beans are typically stronger and more bitter, so you may want to use a little less. Light roasts are milder but may need a bit more to get a fuller flavor.
Want to Be Precise? Use a Scale
If you’re serious about perfecting your coffee, consider measuring by weight instead of volume. According to the Specialty Coffee Association, a good ratio is 55 grams of coffee per liter of water. For a 12-cup pot (about 1.8 liters), that’s around 100 grams of coffee, or about 20 tablespoons, depending on grind density.

Conclusion
So, how many tablespoons of coffee for 12 cups? A great starting point is 18 to 24 tablespoons, depending on your taste. If you’re brewing for a crowd or just want your morning cup to be reliably delicious, stick with the ratio that works best for you. You might need to tweak it a bit, but once you find your sweet spot, it makes every morning smoother.
