Answer: A can of beer contains 12 ounces or 354 ml. This makes a can of beer one standard size for all manufacturers. The volume of a can and a bottle is 12 ounces (355 milliliters) in the US.
The volume of a bottle, a can, or a keg is approximately the same. For each possible drink container type, there’s approximately 1 liter or 33 fluid-ounce total capacity.
The standard size for canned beers is 354 ml or cans that are 273 cubic centimeters. That’s somewhere between 11 oz and 17 oz, depending on the brand and whether it’s a refreshing American-style lager or a strong imperial stout from an English brewery.
Some companies offer 330mL cans, which they claim is equivalent to about 13.2 ounces but many people complain about not really being able to feel satisfied with such smaller servings!
