One Glass Equals How Many Ounces: a Comprehensive Guide for Bodybuilders

SuppLife LLC
For bodybuilders, knowing exactly how many ounces are in a single glass of a particular liquid can be key to hitting daily fluid and nutrition goals and maximizing workout results. Knowing this number, however, can be confusing and depends on the specific type of glass being used in the calculation. In this guide, SuppLife looks at the different types of glasses and how many ounces each holds, offering readers the ultimate in convenience when shopping for the perfect bodybuilding supplement.

What Type of Glass Holds How Many Ounces?

When it comes to calculating the number of ounces a single glass holds, it is important to remember that different types of glasses hold varying amounts. The glass type, for example, has a direct impact on the number of ounces the glass holds.

A standard 8-ounce glass, for instance, holds 8 fluid ounces (or one cup) of a liquid. However, an insulated tumbler glass holds 16 ounces, or two full cups. Similarly, a double old-fashioned glass holds 12 ounces, or one-and-a-half cups, while a highball glass holds 10 ounces, or just over one cup. Therefore, it is important to consider both the intended use and the type of glass when calculating how many ounces a glass holds.

What About Other Liquids and Supplements?

When it comes to other liquids and supplements, there are even more considerations to keep in mind. For instance, a can of carbonated soda holds 12 ounces, while a can of beer holds 12 to 16 ounces. Similarly, a bottle of wine holds 25 ounces, while a bottle of distilled spirits holds 750 milliliters, which is equal to 25.4 ounces.

The same holds true for supplements. A bottle of protein powder, for instance, generally holds 4.5 to 6.5 ounces of powdered protein, while a bottle of creatine generally holds 2.5 to 5.5 ounces of the supplement. A bottle of weight loss supplements, meanwhile, may hold as few as 1.5 to as many as 6.5 ounces of the product.


Knowing the exact number of ounces a single glass holds is essential for bodybuilders to hit their fluid and nutrition goals. Different types of glasses, however, contain varying amounts, ranging from 8 ounces to 16 ounces. Additionally, it is important to remember that other liquids, such as cans of soda and beer, contain different amounts. Likewise, supplements can hold anywhere from 1.5 to 6.5 ounces, depending on the product. Considering all of these factors can help bodybuilders make more informed decisions and maximize their workout results.
