How many Oz is in a can of Coke?

Coca-Cola is one of the most popular sodas in the world, known for its refreshing taste and caffeine kick. But when grabbing a can or bottle from the fridge or vending machine, many people may wonder – how much Coke is actually in that container? Understanding Coke can and bottle sizes by fluid ounces can help you compare portions and decide which size to buy.

Quick Answer

The standard can of Coca-Cola contains 12 fluid ounces (355 mL). This is the typical can size you’ll find in vending machines and grocery stores in the United States.

Standard Can Sizes

Here are some of the most common can sizes for Coca-Cola products and their fluid ounce measurements:

Can Size Fluid Ounces
Standard can 12 fl oz
Sleek can (shorter, thinner can) 12 fl oz
Aluminum bottle 12 fl oz
7.5 oz “mini” can 7.5 fl oz

As you can see, the traditional 12-ounce can is the standard size for a single-serve of Coke. Whether it’s the classic can, sleek can, or aluminum bottle, you typically get 12 fluid ounces of soda.

The 7.5 oz mini can is the smaller portion option, containing just over half the amount of a regular 12 oz can. So if you’re looking to cut back on soda or want a smaller size, the 7.5 oz mini can is a good option.

Larger and Multi-Pack Sizes

In addition to single-serve cans, Coca-Cola produces larger cans and multi-pack options with more fluid ounces of soda per container:

Container Fluid Ounces
16 oz pounder can 16 fl oz
20 oz bottle 20 fl oz
1 liter bottle 33.8 fl oz
2 liter bottle 67.6 fl oz
12-pack of cans 144 fl oz (12 x 12 oz cans)
24-pack of cans 288 fl oz (24 x 12 oz cans)

The 16 oz pounder has 33% more soda than a standard 12 oz can. The 20 oz bottle contains nearly twice as much as a 12 oz can. Then the 1 liter bottle has over 2.5 times as much as a can, while a 2 liter bottle has over 5 times as much soda as a 12 oz can.

Buying Coca-Cola in bulk multi-packs is a good way to stock up and save money per can. A 12-pack contains 12 standard 12 oz cans for a total of 144 fluid ounces of Coke. And a 24-pack contains 24 cans for a whopping 288 fluid ounces total.

How Many Servings in Different Can Sizes?

When counting calories, carbs, or caffeine intake from soda, you may wonder how many servings are in different can sizes. Here is a breakdown:

Can Size Servings
7.5 oz mini can 1 serving
12 oz standard can 1.5 to 2 servings
16 oz pounder can 2 to 2.5 servings
20 oz bottle 2.5 servings

Coca-Cola defines a serving as 8 fluid ounces. So a standard 12 oz can is equal to about 1.5 to 2 servings depending on if you consider it 1.5 or round up to 2.

The mini 7.5 oz can is right around one 8 oz serving. The pounder 16 oz has 2 to 2.5 servings, while a 20 oz bottle equates to 2.5 servings according to the typical serving definition.

Comparing Coca-Cola Can Sizes

When deciding which Coca-Cola to buy, it may help to visualize how the different can sizes compare:

Can Size Height Diameter
7.5 oz mini can 4.75 in 2.5 in
12 oz standard can 4.75 in 2.6 in
16 oz pounder can 5.2 in 3 in

The mini 7.5 oz can is the shortest while the pounder 16 oz can is the tallest. Standard 12 oz cans and mini cans have the same diameter, while pounders are about half an inch wider.

So if you want a smaller portion size, the mini 7.5 oz is the shortest and slimmest. But the pounder 16 oz gives you the most soda for your money, contained in the tallest, widest single-serve can.

Factors That Affect Soda Fizz & Quality

When purchasing any type of canned soda like Coke, you want the best fizz and quality. Here are some factors that affect carbonation and taste:

  • Storage temperature – Store cans in a cool, dry place around 55°F for optimal fizz and taste.
  • Expiration date – Drink cans within 3 months of production for best quality.
  • Container damage – Dents, cracks or leaks let carbonation escape and affect taste.
  • Sunlight exposure – Prolonged direct sunlight exposure can flatten soda’s fizz.
  • Elevation – At higher altitudes, the lower air pressure yields flatter soda.

To get the most fizzy, great tasting Coke from a can, store cans properly and drink them before the expiration date. Inspect cans for damage before purchasing. And be aware of environmental factors like sunlight and elevation that affect carbonation.

Diet Coke vs. Coca-Cola Nutrition Facts

When choosing between varieties of Coke, it’s helpful to compare nutrition facts. Here is a nutrition facts table contrasting 12 oz cans of regular Coca-Cola and Diet Coke:

Nutrition Facts 12 oz Coca-Cola 12 oz Diet Coke
Calories 140 0
Protein 0g 0g
Carbs 39g 0g
Sugar 39g 0g
Sodium 35mg 40mg
Caffeine 34mg 46mg

The main differences between Coca-Cola and Diet Coke are in their calories and carbohydrates coming from high fructose corn syrup versus artificial sweeteners. Diet Coke has no calories, sugar, or carbs, while regular Coke has 140 calories and 39g each of sugar and carbs.

Diet Coke actually contains slightly more caffeine at 46mg vs. 34mg in Coca-Cola. So if you’re limiting calories but still want that caffeine kick, Diet Coke may be the better choice.
