How many tablespoons are in a 12 oz bag of ground coffee?

Coffee is one of the most popular beverages around the world. Whether you’re a casual coffee drinker or a coffee connoisseur, knowing how to measure coffee properly is an important skill. When following a recipe or trying to recreate your favorite coffee shop drink at home, it’s crucial to use the right coffee-to-water ratio. This ensures you get the desired flavor and caffeine kick from your morning brew.

Most coffee bag labels list the weight of the contents, often 12 ounces or 340 grams. But recipes call for volume measurements like tablespoons and cups. So how many tablespoons (Tbsp) are in a typical 12 ounce (oz) bag of ground coffee?

Quick Answer

There are approximately 74 tablespoons (Tbsp) in a 12 ounce (oz) bag of ground coffee.

Calculating Tablespoons from Ounces of Coffee

To determine how many tablespoons fit into 12 ounces of ground coffee, we need to know a couple conversion factors:

  • 1 ounce (oz) = 2 tablespoons (Tbsp)
  • 1 12 ounce bag = 12 x 2 = 24 tablespoons

So based on these simple conversions, a 12 ounce bag contains 24 tablespoons of ground coffee. However, that is only an approximate tablespoon amount. To get a more precise measurement, we need to take into account how much a tablespoon of ground coffee actually weighs.

Weight of a Tablespoon of Ground Coffee

The weight of a single tablespoon of ground coffee can vary slightly depending on factors like the coffee’s grind size, origin, and roast. But generally, one tablespoon of ground coffee weighs between 5-6 grams (0.18-0.21 oz).

For easy math, let’s assume the average weight of a tablespoon of ground coffee is 5.5 grams (0.19 oz).

Doing the Math

Now we can use the weight of a tablespoon to calculate tablespoons based on the total weight of the bag:

  • 1 bag = 12 oz = 340 grams
  • 1 Tbsp = 5.5 grams
  • 340 grams ÷ 5.5 grams/Tbsp = ~62 Tbsp

So based on the true weight measurement, there are approximately 62 tablespoons of ground coffee in a 12 ounce bag.

Why the Discrepancy in Tablespoon Amount?

You may have noticed that the initial calculation said there were 24 tablespoons in 12 ounces of coffee. But when taking the actual weight of a tablespoon into account, we ended up with a total of 62 tablespoons.

What gives?

This discrepancy occurs because a tablespoon of ground coffee weighs more than the generalized conversion factor of 1 oz = 2 Tbsp. When you use the standard weight conversions, it underestimates the true number of tablespoons contained in a 12 oz bag.

The moral of the story is that accuracy matters when working with volume and weight conversions!

Factors that Influence Tablespoons per Ounce

While the average 12 oz bag of ground coffee contains about 62 tablespoons, there are several factors that can result in slight variations:

Coffee Roast Level

Darker roasted coffees are less dense than lighter roasts. This means dark roast ground coffee weighs less per tablespoon. Expect a darker roast to contain closer to 64 Tbsp per 12 oz.

Coffee Grind Size

Finer coffee grinds take up less volume than coarser grinds. So an extra fine espresso grind contains more Tbsp per ounce than a coarse French Press grind.

Bean Origin and Processing

Bean density can also vary based on the coffee plant varietal and processing method. For example, Indonesian coffee beans tend to be denser than beans from Latin America.


Higher altitude coffee beans are typically denser than low altitude beans. This means you’ll get fewer tablespoons per ounce from high grown coffee.

While these factors can change the tablespoons per ounce slightly, the difference is usually only 1-2 tablespoons in a 12 oz bag.

Key Takeaways on Ounces and Tablespoons of Coffee

Here are the key takeaways on relating ounces and tablespoons of ground coffee:

  • Using the generalization of 1 oz = 2 Tbsp underestimates the true tablespoon amount in a bag of coffee.
  • Pay attention to the actual weight of a tablespoon, which is around 5.5 grams for ground coffee.
  • Most 12 oz bags of ground coffee contain approximately 62 Tbsp.
  • Slight coffee variations like roast, grind, and origin can alter the tablespoons per ounce by 1-2 Tbsp.

Tips for Measuring Coffee

Once you know approximately how many tablespoons are in an ounce of ground coffee, here are some tips for measuring it accurately:

Use a Food Scale

For maximum precision, use a small food scale to weigh out coffee grounds instead of relying on spoon measurements. This removes the variability of how much a tablespoon actually weighs.

Level Off Your Spoon

If measuring by the tablespoon, make sure to level off the spoonful of coffee grounds using a knife or your finger. Packing the grounds into the spoon or leaving a heaping mound will throw off the weight.

Use Rounded Tablespoons

Look for a measuring spoon with an oval or round bowl rather than a slender oblong shape. The rounded tbsp will be more accurate for dense ground coffee.

Grind Beans to Order

Buy whole bean coffee and grind it immediately before brewing. This provides the freshest, most flavorful brew.

Weigh Multiple Servings

Use a kitchen scale to weigh out the total amount of ground coffee needed for multiple cups rather than measuring individually.

Frequently Asked Questions

Why don’t ounces and tablespoons of coffee align?

Ounces are a weight measurement while tablespoons are a volume measurement. Ground coffee weighs more per tablespoon than the generalized conversion factor, so the tablespoons per ounce don’t match up perfectly.

Do tablespoons or ounces matter more for coffee?

For accuracy, ounces and grams are better than tablespoons for measuring ground coffee. The weight measurements account for density changes better than volume. But tablespoons can still be used with slight variance if you don’t have a kitchen scale.

Is it better to use a scale or measuring spoons?

A food scale provides the most accuracy and precision for coffee measurements. But measuring spoons are still reasonably accurate as long as you level off the grounds. For best results, invest in both a small kitchen scale and quality stainless steel measuring spoons.

Why are there approximately 62 Tbsp in a 12 oz bag instead of 64?

The conversion uses the approximate weight of 5.5 grams per tablespoon of ground coffee. If the true weight of a tablespoon is slightly more or less for a certain coffee, it will alter the total tablespoons in a 12 oz bag slightly. Small variations in bean density, roast level, grind size, and origin affect the final conversion to tablespoons.

Does coffee grind size or roast change the tablespoons per ounce?

Yes, a finer coffee grind and darker roast both increase the tablespoons per ounce somewhat. Finer grinds take up less volume, so more fit into an ounce. Dark roasts are less dense than light roasts, also increasing tablespoons per ounce. But the difference is minor, only 1-2 Tbsp in a full bag.

The Bottom Line

While the typical generalization is that a 12 ounce bag of ground coffee contains 24 tablespoons, the actual amount is closer to 62 tablespoons when you account for the true weight of a tablespoon of ground beans. However, slight variations in bean density, roast level, grind size, and origin can alter the yield by 1-2 tablespoons. For most recipes, the approximation of 60 tablespoons per 12 ounce bag of ground coffee will provide reliable results.

Understanding the relationship between weight and volume for ground coffee helps ensure your brews have the intended flavor and strength. While using a kitchen scale provides the most precise coffee measurements, you can still achieve good results with measuring spoons. Just be sure to level off the tablespoons, use a rounded spoon, and grind the beans fresh for optimal taste.
