What Are the Coffee Bag Sizes? (with Illustrations)

Coffee Bag Sizes

A lot of people can’t function in the morning without a cup of coffee. Those people should probably think about making coffee at home instead of spending their hard-earned money on overpriced coffee at popular chains (one particular chain comes to mind). If you want to purchase a bag of coffee beans to make at home, you should know what sizes they come in.

The most common coffee bag size is 16 ounces or 1 pound. Other popular coffee bag sizes include half a pound (8 ounces) and 5 pounds. You can also find coffee beans or grounds in 4, 10, and 12-ounce bags.

For the remainder of this brief guide, I’ll explain the various coffee bag measurements and how many servings of coffee you can get from a single bag.

Coffee Bag Sizes

The next time you take a stroll through your local grocery store, try and pass through the hot beverage aisle. You’ll find coffee bags of all sorts of shapes, sizes, colors, and brands. Something else you’ll notice is that the sizes of each bag may differ vastly, especially when comparing between brands.

But if you take a look at the net weight rating of those coffee bags, you’ll discover that many of them have the same figures. Some of the most popular coffee bag (weight) sizes are 8 ounces, 16 ounces (1 pound), and 5 pounds. If you continue to spend time in the hot beverage aisle, you’ll also come across other coffee bag sizes, including 4, 10, and 12 ounces.

As indicated earlier, the size of the coffee bag varies from brand to brand. You’ll even find the physical measurements of one brand vastly different from those of another brand, even if their weights are identical.

As a rough guide, you can take a look at the coffee bag sizes available on coffeebags.com. Here’s a quick preview of how big their half-pound, 1-pound, and 5-pound coffee bags are.

Something worth noting is that these coffee bags will not be filled to the brim. There should be a few inches on the top reserved for rolling down to package the product.

How Many Servings of Coffee per Bag?

How Many Servings of Coffee per Bag

On average, you can get roughly 16 8-ounce servings from a 1-pound bag of pre-ground coffee.

However, the exact number of servings you can squeeze from a coffee bag depends on a variety of factors. First of all, how many ounces of coffee do you drink per serving? Secondly, how strong do you want your coffee? Thirdly and arguably most importantly, what type of coffee are you going to make?

Let’s take a look at each factor individually.

1. Ounces per serving

This refers to how much coffee you drink per serving, which usually depends on the size of your mug or tumbler. The Specialty Coffee Association of America, according to Presto-Coffee, recommends using 10 grams (0.35274 ounces) of coffee grounds per 6-ounce serving. In other words, you would need to prepare around 1.667 grams (0.588 ounces) of coffee grounds to produce each fluid ounce of coffee.

Here’s a brief table that describes how much coffee by weight you’d need per serving.

Serving SizeCoffee Ground Weight
6 oz.10 g (0.35274 oz.)
8 oz.13.33 g (0.4702 oz.)
10 oz.16.667 g (0.5879 oz.)
12 oz.20 g (0.7055 oz.)
18 oz.30 g (1.0582 oz.)
24 oz.40 g (1.4109 oz.)
32 oz.53.33 g (1.8811 oz.)

2. Coffee strength

The figures in the table above describe the recommended amount of coffee grounds per serving of coffee. However, what you consider flavorful, aromatic coffee may not be the same as what the SCAA thinks is right. Perhaps you’re the type of person who prefers hard, strong coffee, or maybe you belong to the opposite end of the spectrum.

Luckily, you can adjust coffee strength (technically, the ratio of dissolved coffee grounds to water) to your liking by adding or removing coffee grounds. If you prefer stronger coffee, increase the weight of the grounds when brewing a fresh batch. If you prefer a lighter kick in the tastebuds, reduce the weight of coffee grounds before starting up your machine.

Some high-tech espresso machines let you adjust coffee strength via the control board. You can use their recommended coffee portions as a guide to determine how strong or “weak” you want your brew.

3. Types of coffee

To make matters even more confusing, the type of coffee you make will determine how much coffee grounds to add. Let’s take a look at 2 different types of coffee that belong to opposite ends of the spectrum—drip coffee and espresso.

Drip coffee is a process where water is pushed through a filter lightly packed with coffee grounds. Espresso follows the same preparation technique, but it uses more coffee grounds and pressurized water to extract more of the flavor and aroma from each granule. What does this mean? Drip coffee requires less ground by weight per serving than espresso.

In addition, a single serving (shot) of espresso is much smaller (between 1 and 1.5 ounces) compared to a standard serving of drip coffee (6 to 8 ounces). So, the ratio between coffee and water is way different.

Here’s how much coffee you’d need to make espresso.

Espresso Serving SizeCoffee Ground Weight
1 to 1.5 oz.6 to 8 g (0.2116 to .02822 oz.)
2 to 2.5 oz. (double)14 to 18 g (0.4939 to 0.6349 oz.)
3 to 3.5 oz. (triple)21 g (0.7408 oz.)

As a rough estimate, you would need roughly 42 grams (1.4815 ounces) of coffee to make 6 shots (roughly 6 ounces) of espresso. Meanwhile, it would talk roughly ¼ of that amount to make a 6-ounce serving of drip coffee.
