Coffee Beans per Cup

If you want to know the secret to a perfect cup of coffee, its attention to detail. There are a lot of factors that you need to control to make a perfect cup of coffee.

One of those factors is the amount of coffee grounds you use. Using too many or too few coffee beans could ruin your cup of coffee. Below we go over how to properly measure out your coffee for the perfect cup of joe.

How to Measure Coffee Beans

The easiest way to measure coffee beans is by using a digital kitchen scale. Take whatever container you will be using to hold your coffee beans in and place it on the scale empty. 

Most scales have a button called TARE on it that will zero out the weight of the bowl to give you an accurate reading. If yours doesn’t, then make a note of the container’s weight and subtract it from what you need. 

For every six ounces of coffee, you will need about two tablespoons of ground coffee. This is around 0.38 ounces or 10.6 grams of whole coffee beans. If you are making more than one cup, just adjust to as much as you need. 

If you don’t have a digital scale, you can grind beans until you have two full tablespoons of ground beans. Then make a note of how many tablespoons of whole beans it took to make that amount ground up. This isn’t as accurate, but it keeps you from carrying around a scale.

Measurements And Water Ratios

There is an easy to remember the rule for measuring out the perfect coffee called the golden ratio

This ratio is 1 gram of coffee grounds for every 18 ml of water, 1:18. If you are measuring out your coffee for the perfect cup, then this is the perfect place to start. You can play with this ratio to tailor your favorite coffee to your specific tastes.

Coffee Beans Measurement Conversions

With coffee beans being measured in weight and coffee being measured by volume, it can get confusing really quickly. The easiest way to remedy this is to convert everything to simple measurements. The standard measure of coffee is two tablespoons. This is equal to about one-eighth of a cup.

Brewing Method Affects The Number Of Beans In Your Coffee

Different brewing methods are going to require different amounts of coffee beans as well. If you are using a drip coffee machine, the grounds are not packed in so you can use fewer coffee beans. If you are using an espresso machine, you will have to use more beans packed tightly into what is called a coffee puck. This changes how many beans you can pack into each cup of coffee.

Bean Weight Or Count: What’s More Important For Making Coffee?

This is a common mistake. The coffee industry measures its bags of coffee by weight and not by the number of beans in each bag. Your coffee grounds needed in each cup are measured in weight the same way. You will need more beans depending on how you are brewing your coffee, but it doesn’t have an impact outside of that.


The best thing to do if you want to accurately measure your coffee is to get a digital kitchen scale. This will take the guesswork out and make you one step closer to perfecting your coffee. 

Start with the golden ratio and experiment for a while to find your preference. After a few tries, you are sure to know exactly how much coffee to use.
