Monster Energy drinks are available in several can sizes, but the exact size depends on the specific Monster product and flavor. In the U.S., Monster’s official website currently lists 12 oz, 16 oz, 19.2 oz, and 24 oz sizes for its Original Green Monster. Some other products are available only in selected sizes.
The 16 oz can is one of the most commonly referenced Monster sizes, but it is not the only option. If you’re comparing Monster cans, knowing the ounces, milliliters, and relative size can make the differences easier to understand.
Quick Answer
Monster Energy cans come in several sizes, depending on the product.
| Monster Can Size | Approx. Milliliters | Approx. Liters |
|---|---|---|
| 12 oz | 355 mL | 0.355 L |
| 16 oz | 473 mL | 0.473 L |
| 18.6 oz | 550 mL | 0.550 L |
| 19.2 oz | 567 mL | 0.567 L |
| 24 oz | 710 mL | 0.710 L |
The most important point is that can availability varies by flavor and market. For example, Monster Original Green currently lists 12 oz, 16 oz, 19.2 oz, and 24 oz on the U.S. Monster website.
What Are the Different Monster Can Sizes?
Monster has a range of can sizes rather than one standard size.
Some of the sizes currently found across Monster’s U.S. product lineup include:
- 12 oz
- 16 oz
- 18.6 oz
- 19.2 oz
- 24 oz
However, a particular flavor may be offered in only one or two of these sizes.
For example, Monster Ultra Zero currently lists 12 oz, 16 oz, 19.2 oz, and 24 oz, while Ultra Sunrise lists 12 oz and 16 oz.
Monster Can Size Chart
Here is a quick comparison of the major sizes.
| Can Size | Fluid Ounces | Approx. mL | Approx. Cups |
|---|---|---|---|
| Small | 12 oz | 355 mL | 1.5 cups |
| Standard | 16 oz | 473 mL | 2 cups |
| Large | 18.6 oz | 550 mL | 2.33 cups |
| Extra Large | 19.2 oz | 567 mL | 2.4 cups |
| Very Large | 24 oz | 710 mL | 3 cups |
The cup conversions are based on 1 U.S. fluid ounce = 29.5735 mL and 1 U.S. cup = 8 U.S. fluid ounces.
How Many Ounces Is a Regular Monster Can?
When people refer to a standard or regular Monster can in the U.S., they often mean the 16 oz can.
A 16 oz Monster contains approximately:
16 fluid ounces = 473 mL
Monster’s Original Green product lists 16 oz among its available sizes.
Many Monster products also provide nutrition information based on a 16-fluid-ounce serving. For example, the Original Green page lists 160 mg of caffeine based on 16 fl oz.
How Many Milliliters Are in a 12 oz Monster?
A 12 oz Monster contains approximately:
12 × 29.5735 = 354.88 mL
So:
12 oz ≈ 355 mL
This is close to the metric can size commonly labeled 355 mL.
Some Monster flavors, including Ultra Sunrise and Ultra Strawberry Dreams, are currently listed in 12 oz and 16 oz sizes.
How Many Milliliters Are in a 16 oz Monster?
A 16 oz Monster contains approximately:
16 × 29.5735 = 473.18 mL
So:
16 oz ≈ 473 mL
This is the size many shoppers will see when buying Monster in the U.S.
How Many Milliliters Are in a 19.2 oz Monster?
A 19.2 oz can contains approximately:
19.2 × 29.5735 = 567.81 mL
So:
19.2 oz ≈ 568 mL
Monster Original Green currently lists 19.2 oz as one of its U.S. can sizes.
The exact metric equivalent is about 567.8 mL, although packaging may use a rounded metric measurement depending on the market.
How Many Milliliters Are in a 24 oz Monster?
A 24 oz Monster contains approximately:
24 × 29.5735 = 709.76 mL
So:
24 oz ≈ 710 mL
Monster Original Green and Monster Zero Sugar currently list 24 oz among their U.S. sizes.
A 24 oz can therefore contains about 1.5 times as much liquid as a 16 oz can.
12 oz vs. 16 oz Monster
The 12 oz and 16 oz cans are two useful sizes to compare.
| Feature | 12 oz | 16 oz |
|---|---|---|
| Volume | 12 fl oz | 16 fl oz |
| Approx. mL | 355 mL | 473 mL |
| Difference | — | 4 oz more |
| Relative size | 75% | 100% |
| Approx. cups | 1.5 | 2 |
A 16 oz can contains 4 more fluid ounces than a 12 oz can.
That means the 16 oz can contains approximately 33% more liquid than the 12 oz can.
Both sizes are available for several Monster products, although availability depends on the flavor.
16 oz vs. 24 oz Monster
The difference is more noticeable between 16 oz and 24 oz cans.
| Feature | 16 oz | 24 oz |
|---|---|---|
| Volume | 16 fl oz | 24 fl oz |
| Approx. mL | 473 mL | 710 mL |
| Difference | — | 8 oz more |
| Relative size | 67% | 100% |
| Approx. cups | 2 | 3 |
A 24 oz Monster contains 50% more liquid than a 16 oz Monster.
This does not necessarily mean every nutritional value is 50% higher because nutritional information depends on the specific product and serving information.
19.2 oz vs. 24 oz Monster
These are both larger can options.
| Feature | 19.2 oz | 24 oz |
|---|---|---|
| Volume | 19.2 fl oz | 24 fl oz |
| Approx. mL | 568 mL | 710 mL |
| Difference | — | 4.8 oz more |
| Approx. cups | 2.4 | 3 |
The 24 oz can contains 25% more liquid than a 19.2 oz can.
Monster Original Green currently lists both 19.2 oz and 24 oz options.
Is a Monster Can 16 oz?
Often, yes, but not always.
The 16 oz size is a common Monster can size, and many Monster products are sold in 16 oz cans. However, the official Monster website shows that some products also come in 12 oz, 19.2 oz, or 24 oz cans.
Therefore, if you’re asking about a specific Monster flavor, check the size printed on that product rather than assuming every Monster can is 16 oz.
What Is the Largest Monster Can?
Among the U.S. sizes currently listed on Monster’s official product pages, 24 oz is the largest size shown for products such as Original Green and Monster Zero Sugar.
A 24 oz can contains approximately:
710 mL
or:
0.71 liters
It contains 8 more fluid ounces than a 16 oz can.
What Is the Smallest Monster Can?
A 12 oz can is one of the smaller standard Monster sizes currently listed on Monster’s U.S. website.
Monster Original Green and several Ultra products are available in 12 oz cans.
A 12 oz can contains approximately:
355 mL
or:
0.355 liters
Are All Monster Flavors Available in the Same Can Sizes?
No.
This is an important point when comparing Monster products.
For example:
| Monster Product | Sizes Listed on Official U.S. Site |
|---|---|
| Original Green | 12, 16, 19.2, 24 oz |
| Zero Sugar | 16, 24 oz |
| Ultra Zero | 12, 16, 19.2, 24 oz |
| Ultra Sunrise | 12, 16 oz |
| Nitro Super Dry | 16 oz |
| Super-Premium Import | 18.6 oz |
These listings are product-specific and can change.
Why Do Monster Cans Come in Different Sizes?
Different can sizes give consumers different volume options.
A smaller can may contain less beverage, while larger cans contain more.
The choice of size can also vary based on:
- Product type
- Flavor
- Market
- Packaging format
- Retail availability
For example, Monster’s Super-Premium Import is currently listed as an 18.6 oz can, while Nitro Super Dry is listed in 16 oz.
Monster Can Sizes in Cups
If you’re more familiar with measuring drinks in cups, the conversions are simple.
Since one U.S. cup equals 8 fluid ounces:
| Monster Can | Approximate U.S. Cups |
|---|---|
| 12 oz | 1.5 cups |
| 16 oz | 2 cups |
| 18.6 oz | 2.325 cups |
| 19.2 oz | 2.4 cups |
| 24 oz | 3 cups |
So a 16 oz Monster is exactly 2 U.S. cups by volume, while a 24 oz Monster is exactly 3 U.S. cups.
Monster Can Sizes in Liters
For metric measurements:
| Can Size | Approximate Liters |
|---|---|
| 12 oz | 0.355 L |
| 16 oz | 0.473 L |
| 18.6 oz | 0.550 L |
| 19.2 oz | 0.568 L |
| 24 oz | 0.710 L |
This makes the 24 oz can approximately 0.71 liters.
A 16 oz can is approximately 0.47 liters.
How Much Bigger Is a 24 oz Monster Than a 16 oz?
The difference is:
24 − 16 = 8 oz
To calculate the percentage increase:
8 ÷ 16 × 100 = 50%
Therefore, a 24 oz can contains 50% more liquid than a 16 oz can.
In metric terms:
710 mL − 473 mL ≈ 237 mL
So the 24 oz can contains approximately 237 mL more beverage than the 16 oz version.
How Much Bigger Is a 16 oz Monster Than a 12 oz?
The difference is:
16 − 12 = 4 oz
The percentage increase compared with the 12 oz can is:
4 ÷ 12 × 100 ≈ 33.3%
So a 16 oz can contains about 33% more liquid than a 12 oz can.
In metric terms:
473 mL − 355 mL ≈ 118 mL
Monster Can Size Comparison
Here is the complete volume comparison in one table:
| Can Size | mL | Liters | Cups | Compared With 16 oz |
|---|---|---|---|---|
| 12 oz | ~355 | 0.355 | 1.5 | 25% less |
| 16 oz | ~473 | 0.473 | 2 | Standard reference |
| 18.6 oz | ~550 | 0.550 | 2.325 | ~16% more |
| 19.2 oz | ~568 | 0.568 | 2.4 | 20% more |
| 24 oz | ~710 | 0.710 | 3 | 50% more |
This table compares liquid volume, not the physical height or diameter of the cans.
Does a Bigger Monster Can Have More Caffeine?
Generally, a larger can can contain more total caffeine if the same formulation and concentration are used, but you should not assume that simply from the can size.
Caffeine levels vary by Monster product and flavor.
For example, Monster’s Original Green page lists 160 mg of caffeine based on 16 fl oz, while several Ultra products list 150 mg based on 16 fl oz.
Always check the nutrition label for the exact product and can size.
Are Monster Can Sizes the Same Worldwide?
Not necessarily.
Can sizes and product availability can vary by country and market. The Monster U.S. website is therefore useful for U.S. product information, but shoppers in other countries may encounter different metric can sizes or product availability.
The size printed directly on the can is the best reference for the product you’re purchasing.
