How Big Is a Coffee Scoop? Scoops, Tablespoons and Grams
Share
Coffee recipes love to say “one scoop per cup,” but how big is a coffee scoop? The standard coffee scoop holds 2 level tablespoons, which is 1/8 cup or about 30 ml (1 US fluid ounce) of volume. Filled with medium-ground coffee and leveled, that is roughly 9 to 10 grams. The trouble is that not every scoop is standard, “cup” on a coffee maker rarely means 8 ounces, and grounds vary in density.
This guide gives you the conversions, worked examples for a mug and a full carafe, and a quick way to calibrate your own scoop so your coffee tastes the same every morning.
Key takeaways
- A standard coffee scoop = 2 tablespoons = 1/8 cup = about 30 ml.
- A level scoop of ground coffee weighs roughly 9–10 g; a level tablespoon about 4.5–5 g.
- A common drip guideline is about 55 g of coffee per liter of water, around 1:18.
- Coffee maker “cups” are often 5–6 fl oz, not 8.

How many tablespoons in a coffee scoop?
Two. The classic coffee scoop that comes with drip machines and many bags is sized at 2 US tablespoons. One US tablespoon is about 14.8 ml, so a level scoop holds about 29.6 ml, which is also 1 US fluid ounce or 1/8 cup.
Machine makers use the same unit. Moccamaster’s own brewing chart, for example, is written in level “2 Tbsp” scoops: 6 scoops (about 55 g) for 1 liter of water, and 10 scoops (about 99 g) for its full 1.8-liter carafe.
Watch out for exceptions:
- Some scoops packed with espresso machines or capsule-style refillables are 7 g or smaller.
- Decorative wooden or metal scoops can be anything from 1 to 3 tablespoons.
- A heaped scoop can hold 30–50% more than a level one.
Scoops to grams: the conversion table
These figures are for medium-ground coffee, leveled off. Fine espresso grinds pack a little denser; coarse grinds and dark roasts weigh a little less per spoon.
| Measure | Volume | Approx. ground coffee |
|---|---|---|
| 1 teaspoon | about 5 ml | 1.5–2 g |
| 1 tablespoon | about 15 ml | 4.5–5 g |
| 1 standard scoop (2 tbsp) | about 30 ml | 9–10 g |
| 1/4 cup (4 tbsp, 2 scoops) | about 60 ml | 18–20 g |
| 1/2 cup (8 tbsp, 4 scoops) | about 120 ml | 36–40 g |
Why a range? A scoop measures volume, but extraction depends on weight. Roast level, grind size and how firmly the coffee settles all change how many grams fit in the same space. That is why serious brewers use a coffee scale.
How big is a coffee scoop in practice? Worked examples
The formula is simple:
Coffee (g) = water (ml) ÷ ratio, then scoops = coffee (g) ÷ 9.5
A ratio of 1:16 makes a fuller cup; 1:18 is lighter and close to the common 55 g per liter guideline. More on choosing a ratio in our coffee-to-water ratio guide.
Example 1: one 12 oz mug
12 fl oz is about 355 ml. At 1:16, 355 ÷ 16 = 22.2 g of coffee. Divide by 9.5 g per scoop and you get 2.3 scoops, so about 2 1/4 level scoops (or 4 1/2 tablespoons).
Example 2: a full 12-cup drip machine
Many US drip machines count a “cup” as 5 fl oz. Twelve of those is 60 fl oz, about 1,774 ml. At 55 g per liter, 1.774 × 55 = 98 g, or about 10 level scoops. If your machine uses 6 oz cups, the same carafe holds about 2,129 ml and needs about 117 g, or 12 scoops.
| Water | At 1:16 | At 1:18 | Level scoops (1:16 / 1:18) |
|---|---|---|---|
| 6 fl oz (177 ml) | 11 g | 10 g | 1 1/4 / 1 |
| 8 fl oz (237 ml) | 15 g | 13 g | 1 1/2 / 1 1/3 |
| 10 fl oz (296 ml) | 18.5 g | 16.5 g | 2 / 1 3/4 |
| 12 fl oz (355 ml) | 22 g | 20 g | 2 1/4 / 2 |
| 16 fl oz (473 ml) | 30 g | 26 g | 3 / 2 3/4 |
The “one scoop per cup” rule, tested
One level scoop (about 9.5 g) per 6 oz cup works out to roughly 1:18.6, a light-to-standard cup. Per 8 oz mug it becomes about 1:25, which most people find weak. That is why so many people think their coffee maker makes thin coffee: they follow the rule with a big mug.
Calibrate your own scoop in 2 minutes
- Put a cup on a kitchen scale and zero it.
- Add three level scoops of your usual coffee, ground the way you brew it.
- Divide the weight by three. That is your scoop’s real number.
- Write it on a piece of tape on the canister. Now any recipe in grams converts in your head.
Repeat when you change grind, roast level or coffee, because a dark roast like French Roast weighs less per scoop than a dense light roast such as Blonde.
Grind matters as much as measuring
The right amount of coffee only works with the right grind. Our ground coffee comes in three grinds: Coarse for French press and cold brew, Standard for drip and Espresso for espresso machines and moka pots. If you buy whole beans, see our grind size chart. A good everyday coffee to dial in your scoops is Breakfast Blend, a smooth medium roast, or House Blend for nutty, sweet chocolate notes.
Coffee scoop FAQ
Can I use a measuring cup instead of a scoop?
Yes. A 1/4 cup measure equals two standard scoops, about 18–20 g of ground coffee when leveled, which suits a 10 oz mug at about 1:16.
Is a coffee scoop 1 or 2 tablespoons?
A standard coffee scoop is 2 tablespoons. Some small scoops are 1 tablespoon, so check yours with water: two tablespoons of water should fill it exactly.
How many grams is a scoop of coffee?
About 9–10 g of ground coffee for a level 2-tablespoon scoop.
How many scoops of coffee for 4 cups?
For four 5 oz cups (about 590 ml), use roughly 3 1/2 level scoops (33 g). For four 8 oz mugs (about 950 ml), use about 5 1/2 to 6 scoops (52–59 g).
How many scoops of coffee for a French press?
A 34 oz (1 liter) French press takes about 60–65 g at 1:16, which is 6 1/2 to 7 level scoops of coarse ground coffee.
