If you’ve ever wondered how many grams of coffee in a tablespoon, you’re not alone. This simple question is the key to making a better cup, but the answer isn’t always straightforward.
Using a tablespoon to measure coffee is common, especially when you don’t have a scale handy. But a tablespoon of coffee can weigh different amounts depending on several factors. Getting this measurement right can make the difference between a weak, bitter, or perfectly balanced brew. Let’s look at what really affects that weight in your spoon.
How Many Grams Of Coffee In A Tablespoon
On average, one level tablespoon of ground coffee weighs about 5 to 7 grams. A slightly heaped tablespoon is typically around 8 to 10 grams. However, this is a broad range, and understanding why is crucial for accuracy.
The most important factors are the coffee’s roast, grind size, and how you fill the tablespoon. A dark roast coffee bean is less dense than a light roast bean. This means a tablespoon of dark roast will weigh less than a tablespoon of light roast, even though they take up the same volume.
Key Factors That Change the Weight
Here’s what changes the grams in your tablespoon:
- Grind Size: Finely ground coffee packs more tightly. A tablespoon of fine espresso grind can weigh up to 7-8 grams. Coarse grind for a French press is airier and may weigh only 5-6 grams.
- Roast Level: As mentioned, darker roasts are less dense. A tbsp of dark roast weighs less than a tbsp of light roast.
- Measurement Style: A level tablespoon, a rounded tablespoon, and a heaping tablespoon are all different. For consistency, always aim for level.
- Bean Variety: The type of coffee bean (like Arabica vs. Robusta) and its origin can slightly affect density and weight.
Why Grams Are Better Than Tablespoons
Using a digital kitchen scale is the single best way to improve your coffee. Volume measurements (like tablespoons) are inconsistent, but weight (grams) is precise.
When a recipe calls for a coffee-to-water ratio, it’s based on weight. Two tablespoons of a light roast fine grind and two tablespoons of a dark roast coarse grind will have different weights. This leads to different strengths in your cup, even though you used the same number of spoons.
Switching to grams gives you control and repeatability. You can make your perfect cup every single time.

Converting Common Coffee Recipes
Many classic coffee methods use tablespoon measurements. Here’s how to translate them into more accurate gram-based ratios.
For a Standard 12oz (355ml) Mug
A common rule is 2 tablespoons of coffee per 6 ounces of water. For a 12oz mug, that’s 4 tablespoons. In grams, using a medium grind, that’s roughly 24 grams of coffee. A better approach is to use the golden ratio of 1:16 (coffee to water). For 355ml of water, you’d use about 22 grams of coffee.
For a Full Coffee Pot (10 cups)
A typical “cup” on a coffee maker is 5 ounces. A 10-cup pot brews 50 ounces (about 1.5 liters). The old standard is 1 tablespoon per “cup,” so 10 tablespoons. In grams, that’s roughly 60 grams of coffee. Using a 1:16 ratio for 1.5 liters of water, you’d actually want about 94 grams of coffee. This shows how tablespoon measurements can lead to under-extraction and weak coffee.
Step-by-Step: How to Measure Without a Scale
If you don’t have a scale yet, you can improve your tablespoon method. Follow these steps for better consistency.
- Choose Your Spoon: Use a proper measuring tablespoon, not a random eating spoon from your drawer.
- Pick a Grind: Stick with one grind size for your preferred method as much as possible. Switching between fine and coarse will throw off your measurements.
- Fill Correctly: Spoon your coffee into the tablespoon gently. Don’t tap or pack it down. Use the flat side of a knife to sweep off the excess for a truly level measure.
- Adjust to Taste: Start with 2 level tablespoons per 6oz of water. If it’s too weak, add half a tablespoon more next time. If it’s too strong or bitter, use a bit less.
Choosing and Using a Kitchen Scale
Investing in a small digital scale is a game-changer. Look for one that can measure in 0.1-gram increments, has a tare function, and is easy to clean.
Here’s how to use it for coffee:
- Place your empty brewer or filter on the scale.
- Press the “Tare” or “Zero” button. This resets the weight to zero.
- Add your ground coffee until you reach the desired gram weight.
- Tare the scale again, then add your water by weight for a perfect ratio.
The Science of Coffee-to-Water Ratios
Once you measure in grams, you can master ratios. The ratio tells you how much water to use for a given amount of coffee.
- Strong Brew (bold flavor): Use a 1:15 ratio (e.g., 20g coffee to 300g water).
- Standard Brew (balanced): Use a 1:16 or 1:17 ratio (e.g., 22g coffee to 352g water).
- Lighter Brew (more delicate): Use a 1:18 ratio (e.g., 20g coffee to 360g water).
Experiment to find your favorite. Just remember to keep the ratio consistent once you find it.
Common Mistakes When Using Tablespoons
Avoid these errors to make better coffee with your spoon.
- Using an Eating Spoon: Dining spoons vary wildly in size. A measuring spoon is standardized.
- Packing the Coffee Down: This compresses the grounds, so you use much more coffee than intended, leading to over-extraction and bitterness.
- Ignoring Grind Changes: If you buy pre-ground for drip but then use it for a French press (which needs coarse), your tablespoon will be wrong. The finer particles in drip grind will make a heaver, stronger French press.
- Forgetting the Roast: Switching between a bag of light and dark roast? Remember to adjust slightly—you might need a bit more dark roast by volume to get the same strength.
Specialty Methods and Their Measurements
Different brewing techniques have specific needs.
French Press
Uses a coarse grind. A level tablespoon of coarse grind is lighter. A standard 8-cup (32oz) press often calls for 8 tablespoons. That’s roughly 40-48 grams. A good starting ratio is 1:15, so for 900ml of water, use 60 grams of coffee. See the big difference? Tablespoons can really undershoot.
Pour Over (V60, Chemex)
Uses a medium grind. Precision is key here. A typical recipe for a 500ml pour over uses about 30-32 grams of coffee. That’s about 5 level tablespoons, but weighing is highly recommended for clarity and taste.
Espresso
Uses a very fine grind and is all about weight. A single shot uses 7-9 grams of coffee, and a double uses 16-20 grams. A tablespoon of fine espresso grind is about 7 grams, but it’s never used for measurement because being off by a single gram ruins the shot. A scale is essential.
AeroPress
Very versatile. A standard recipe uses one rounded AeroPress scoop (which is about 2 tablespoons) for ~200ml of water. That scoop is roughly 14-16 grams. Many AeroPress champions weigh their coffee, often using 11-15 grams for a more concentrated brew.
FAQ Section
How many grams is 1 tablespoon of ground coffee?
On average, 1 level tablespoon of medium-ground coffee is about 6 grams. It can range from 5 to 7 grams depending on the factors we discussed.
Is a coffee scoop the same as a tablespoon?
Not usually. A standard coffee scoop is often 2 tablespoons, or about 10-12 grams if you fill it level. Always check the size of your specific scoop to be sure.
How many tablespoons is 20 grams of coffee?
For a medium grind, 20 grams of coffee is roughly 3 and a 1/3 level tablespoons. This is why a scale is easier—it’s hard to measure a third of a tablespoon accurately.
Does the type of coffee affect the weight per tablespoon?
Yes, absolutely. A light roast coffee is denser than a dark roast, so a tablespoon of light roast will weigh more. A oily dark roast bean might also clump differently in the spoon.
How can I measure coffee grams without a scale?
You can use the spoon method, but for better accuracy, use measuring spoons and always level them off. For consistency, try to use the same coffee, roast, and grind each time. But for true accuracy, a cheap scale is your best bet.
Final Tips for Perfect Measurement
To sum it all up, here are the key takeaways.
- Embrace the Scale: It’s the best investment for better coffee. Start with a simple, inexpensive model.
- If Using Spoons, Be Consistent: Use real measuring spoons, level them off, and note the roast and grind.
- Learn Your Ratio: Find a coffee-to-water ratio you like (start with 1:16) and apply it by weight.
- Adjust for Taste: If your coffee is sour, you might need more coffee or a finer grind. If it’s bitter, you might need less coffee or a coarser grind. Change one variable at a time.
- Whole Bean Advantage: Weigh your whole beans before you grind them. This ensures you use the exact right amount and keeps your grinder cleaner.
Understanding how many grams are in a tablespoon of coffee is the first step toward more consistent and enjoyable brewing. While the tablespoon is a handy tool, its variability is it’s biggest flaw. Moving to gram-based measurements gives you control and takes the guesswork out of the process. Your morning routine will become simpler, and your coffee will taste better. Start by trying one brew with a scale—you might be surprised by the difference it makes.
