How much coffee per cup is the question that decides whether your morning is good or sad. Use too little and the pot tastes like brown water. The frustrating part is that the answer changes depending on what you call a cup. Let me clear it up fast, give you a chart and a calculator and then show you why most home coffee comes out weak. For the deeper math behind all of this, see my coffee to water ratio guide.

Use about 1 to 2 level tablespoons of ground coffee for every 6 ounce cup. One level tablespoon is roughly 5 grams.
For a balanced cup I use a little under 2 tablespoons per 6 ounce cup. If you like it strong, use a full 2. If you like it mild, drop closer to 1. The catch is the word cup, and that is where most people go wrong. More on that below.
Set your pot, strength and beans. Flip it to work backward from the coffee you have.
Grams follow water divided by your strength ratio. Grind and roast change how many spoons that weight fills, from about 4 to 6 grams per level tablespoon.
Here is the quick reference at a balanced strength. Remember, these are the 6 ounce cups your coffee maker counts, not big mugs.
| Cups | Water | Coffee (tbsp) | Coffee (grams) |
|---|---|---|---|
| 1 cup | 6 oz | 2 tbsp | 11 g |
| 2 cups | 12 oz | about 4 tbsp | 22 g |
| 4 cups | 24 oz | about 9 tbsp | 44 g |
| 8 cups | 48 oz | about 18 tbsp | 88 g |
| 12 cups | 72 oz | about 26 tbsp | 130 g |
The numbers only help if the units make sense. Here are the three that trip people up.
One level tablespoon of ground coffee weighs about 5 grams. It shifts a little with grind and bean, from roughly 4 to 7 grams, but 5 is a safe number to plan with. Heaping spoons throw this off, so level them.
A standard coffee scoop holds about 2 tablespoons, which is roughly 10 grams. So one scoop covers two 6 ounce cups. Check your scoop though, because the little ones packed with cheap makers are often smaller than a real tablespoon.
Here is the trick that fixes most weak coffee. A coffee maker cup is 6 ounces, not a mug. Your travel mug might hold 16 ounces, which is almost three coffee maker cups. So when a carafe says 12 cups, that is 72 ounces, not twelve big mugs. Measure your coffee against the water you actually pour in and the confusion disappears.
The same math scales up. Here are the common pot sizes.
A 4 cup maker holds about 24 ounces of water. Use around 44 grams of coffee, which is roughly 9 level tablespoons or a little over 4 scoops.
An 8 cup pot is about 48 ounces. Use around 88 grams, roughly 18 tablespoons or 9 scoops.
A full 12 cup carafe is about 72 ounces. Use around 130 grams, roughly 26 tablespoons or 13 scoops. For 10 cups, drop to about 110 grams.
Taste it, then tune.
Keep the water the same and change only the coffee. That keeps the flavor clean instead of bitter.
Almost always one of these.
Fix the amount first. It solves weak coffee more often than any fancy upgrade.
Quick answers from years of brewing at home.
About 1 to 2 level tablespoons of ground coffee per 6 ounce cup. I use a little under 2 for a balanced cup. One level tablespoon is roughly 5 grams.
A 12 cup maker holds about 72 ounces of water. Use around 130 grams of coffee, which is roughly 26 tablespoons or about 13 scoops.
A scoop is about 2 tablespoons, so one scoop covers two 6 ounce cups. For a single cup, use half a scoop.
Usually the cup size fooled you. Coffee makers count 6 ounce cups, not mugs, so the carafe holds more water than you think. Match your coffee to the real water amount and the weakness goes away.
