How Many Ounces in A Coffee Cup? [With Proper Explanation]

Have you ever wondered how many ounces in a coffee cup can make you a perfect cup of joe?

Maybe you’ve tried experimenting with different amounts, and different cup sizes, but you just can’t seem to get it right.

Or maybe you’re wondering how to convert ounces and fluid ounces into other measurements so you can be sure to get the amounts correct according to package directions.

We all know that the amount of coffee ground you use in your coffee cup or mug can make a big difference in how your coffee tastes. But how much is really the right amount? And does it differ depending on the type of mug or cup you’re using? Here’s a deep dive into our research on the matter to help answer the “how many ounces in a coffee cup” question.

How Many Ounces in A Coffee Cup: The Explanation

Standard Size of a Coffee Cup

If you want to know how many ounces are in a coffee cup, the answer would depend on the size of the cup. Say you buy yourself a regular cup of coffee at Starbucks or Panera or any restaurant that serves coffee. The cup size would most likely be around 8 ounces.

That said, some restaurants or coffee houses may consider 8 ounces to be the “small” size and 12 ounces to be the “standard” size.

At Starbucks, an 8-ounce cup is labeled “short,” and a 12-ounce cup is labeled “tall.” Which one is standard? That would depend on who you ask!

Other common cup sizes include 6-ounce, 16-ounce, and 20-ounce.

Also, if you’re ordering an espresso shot, the standard size is going to be much smaller: just 2 ounces.

Standard Size of a Coffee Mug

So how many ounces are there in a coffee mug? Once again, the standard size is typically 8 ounces, but this can vary.

Ceramic mugs for home use come in almost as many sizes as the paper cups your coffee comes in at restaurants. Common sizes are 6, 8, 10, and 12 ounces, but it’s not uncommon to find both smaller and larger mugs depending on the type of coffee you’re making.

Speaking of which, let’s look at the different coffee types and the standard cup/mug size for each.

Standard Coffee And Mug Size Based on Coffee Type

You may need different-size cups or mugs depending on the way you usually like your coffee. The following table breaks down the different coffee types and cup sizes, with the help of Shutterfly and Latte Love Brew:

Coffee TypeCup/Mug Size
Espresso shot2-3 ounce
Cappuccino5-6 ounce
Classic8-15 ounce
Latte8-15 ounce
Iced Coffee12-20 ounce

How Much Coffee To Pour In A Coffee Cup/Mug: The Calculation

So now we come to the big question: how do you create that perfect cup of coffee at home? How much coffee should you use for each cup you brew?

The first thing to consider is, how many ounces is your coffee mug. If you have a regular 6-8 ounce mug, you’ll probably want to use about one ounce of dry coffee grounds. If you like your coffee extra strong, it’s okay to use more, or if you prefer a weaker cup, you can easily use less.

Also, the number of grounds you need may depend on the brand of coffee you choose. Most packages of coffee will come with directions for how to brew the perfect cup, but these suggestions will depend not only on personal taste but on the freshness of the coffee as well as the other flavors added to a particular brew.

If you have a larger mug, adjust your amount of coffee grounds accordingly.

For a 12-ounce cup, you’ll need about an ounce and a half, give or take depending on your taste.

For a 6-ounce cup, use about three-quarters of an ounce.

For a 2-ounce espresso shot, you’ll typically use even fewer grounds, but that will all depend on taste and just how strong you want your shot to be.

Conversion From Fluid Ounce to Milliliter

One fluid ounce converts to about 29.6 milliliters. Most coffee cups and mugs hold 8 fluid ounces or 236.6 mL. As noted above, espresso shots typically come in 2-fluid-ounce amounts or 59.1 mL. For other common amounts, refer to the table below:

Fluid Ounces (fl. oz.)Milliliters (mL)

Conversion From Fluid Ounce to Grams And To Tablespoon

One ounce equals 28.3 grams or 2 tablespoons. So if you want to use one ounce of coffee grounds for one cup of coffee, you would use 2-level tablespoons or just over 28 grams. For other conversions, see the table below:

How to choose a coffee cup/mug for home

With so many different sizes and styles, how do you know which type of coffee mug to buy for your own use? There are several factors to take into consideration.

First, what type of coffee do you most often make yourself?

If you’re mostly brewing a standard cup of coffee or latte, chances are you’ll only need a basic 8-ounce cup (or several).

If you drink a lot of coffee or make iced coffee, you may want to choose a larger mug. If you mostly make cappuccinos or espressos, you’ll want to choose a smaller mug.

Secondly, do you take your coffee on the go a lot? You may want to invest in a travel mug of some kind. These lidded coffee cups will insulate your coffee and keep it from spilling when you’re on the move.

Thirdly, do you need a cup for every type of coffee? Then why not buy mugs in various sizes and styles? You can’t go wrong if you have a mug or cup for any occasion.


So, you’ve learned how many ounces are in a coffee cup, what sizes of cups and/or mugs to use for different coffee drinks, how to convert an ounce into other measurements, and how to choose the perfect mug for your home. Now that you know all about the different types of coffee and mug sizes, what kind of cup will you brew?

Enjoy Your Coffee!
