Discover the Surprising Weight of a Styrofoam Cooler: How Much Does It Weigh?

A Styrofoam cooler can weigh anywhere from 0.01 ounces to 7.3 pounds, depending on its size, capacity, and the thickness and density of the Styrofoam used. Understanding the weight of a Styrofoam cooler is crucial for various applications, such as transportation, storage, and DIY projects. In this comprehensive guide, we’ll dive deep into the technical specifications, weight calculations, and practical considerations for Styrofoam coolers.

Understanding Styrofoam Cooler Weights

Styrofoam coolers come in a wide range of sizes and capacities, each with its own unique weight characteristics. Let’s explore some specific examples:

Small Styrofoam Coolers

A 6-quart Styrofoam cooler from Cold Freight Services measures 11″ x 11″ x 7.5″ (L x W x H) and weighs next to nothing, typically around 0.01 ounces or less. These compact coolers are incredibly lightweight, making them easy to transport and handle.

Medium Styrofoam Coolers

A 16-quart Styrofoam cooler from measures 16″ x 13″ x 8.5″ (L x W x H) and weighs approximately 1.2 pounds. This size is a popular choice for personal use, picnics, and small gatherings.

Large Styrofoam Coolers

The 90-quart Styrofoam cooler from Air Sea Containers measures 29″ x 15″ x 12″ (L x W x H) and weighs 7.3 pounds. This extra-large cooler is designed for commercial or industrial applications, such as transporting temperature-sensitive goods or storing large quantities of food and beverages.

It’s important to note that the weight of a Styrofoam cooler can also be affected by the inclusion of a shipping box or other accessories. For example, the 90-quart cooler from Air Sea Containers comes with a brown shipping box that adds to its overall weight.

Calculating Styrofoam Cooler Weight

How Much Does a Styrofoam Cooler Weigh

The weight of a Styrofoam cooler can be calculated using a simple formula that takes into account the cooler’s dimensions, the density of the Styrofoam, and the thickness of the material.

The formula is as follows:

Weight = (Length x Width x Height) x Density x Thickness

– Length, Width, and Height are the internal dimensions of the cooler in inches.
– Density is the density of the Styrofoam in pounds per cubic foot.
– Thickness is the thickness of the Styrofoam in inches.

Let’s apply this formula to the 90-quart Styrofoam cooler from Air Sea Containers:

  • Dimensions: 29″ x 15″ x 12″ (L x W x H)
  • Density of Styrofoam: 1.0 pounds per cubic foot
  • Thickness of Styrofoam: 1.5 inches

Plugging these values into the formula:
Weight = (29 x 15 x 12) x 1.0 x 1.5 = 7.03 pounds

Therefore, the 90-quart Styrofoam cooler from Air Sea Containers weighs approximately 7.03 pounds.

DIY Styrofoam Cooler Weight Considerations

If you’re interested in making your own Styrofoam cooler, the weight will depend on the size and thickness of the Styrofoam you use. As a general guideline, a standard 1-1/2″ thick Styrofoam sheet weighs about 0.7 pounds per square foot.

For example, if you use a single sheet of 1-1/2″ thick Styrofoam to create a cooler with the dimensions of 29″ x 15″ x 12″ (L x W x H), the weight of the cooler would be approximately 5.4 pounds.

However, keep in mind that the weight of a homemade Styrofoam cooler can vary depending on the specific materials used, the thickness of the Styrofoam, and any additional components, such as a lid, handles, or a shipping box.

Factors Affecting Styrofoam Cooler Weight

Several factors can influence the weight of a Styrofoam cooler, including:

  1. Size and Capacity: Larger coolers with higher capacities generally weigh more than smaller, lower-capacity models.
  2. Styrofoam Thickness: Thicker Styrofoam walls result in a heavier cooler, while thinner walls lead to a lighter weight.
  3. Styrofoam Density: Coolers made with higher-density Styrofoam will weigh more than those with lower-density Styrofoam.
  4. Accessories and Packaging: Additional components like lids, handles, and shipping boxes can add to the overall weight of the cooler.

Understanding these factors can help you select the appropriate Styrofoam cooler for your needs, whether it’s for transportation, storage, or a DIY project.


The weight of a Styrofoam cooler can vary significantly, ranging from a mere 0.01 ounces for a small 6-quart model to 7.3 pounds for a large 90-quart cooler. By understanding the technical specifications, weight calculations, and practical considerations, you can make an informed decision when choosing or creating a Styrofoam cooler that meets your requirements.

Remember, the weight of a Styrofoam cooler is not just a number – it can impact factors like portability, shipping costs, and overall functionality. By keeping these insights in mind, you can ensure that your Styrofoam cooler is the perfect fit for your needs.
