Shipping your cargo safely requires understanding the different types and sizes of shipping containers. We cover everything you need to know about shipping container size, the differences, what size is best for you and where to obtain them.
When it comes to choosing a container size, you have a lot of options. In fact, it’s a huge decision. Saving money and keeping your cargo safe can be achieved with the right container size.
History of Shipping Container Sizes
A standard shipping container was invented in 1956 by Malcolm McLean. In the past, there wasn’t always two standard sizes for shipping containers. In the days before containers were widely used, stuff was shoved into sacks, drums, and pallets. Then they’re loaded straight onto the ships. Back then it would take about 2-3 weeks to fully load the ship up.
Standard containers have proven to be beneficial from the outset. Consequently, more goods could be shipped simultaneously, and less time was wasted loading and unloading. The use of containers also allowed fragile items to be shipped without fear of damage.
We’ll check out a few popular container sizes now.

Sizes of Shipping Containers
Freight containers most used in shipping are ISO standards. There are 8 ft wide and 8 ft 5 high containers available in 20 ft and 40 ft.
These durable containers are ideal for transporting cargo, thanks to their aluminium or steel construction.
Size of 20 Foot Shipping Containers
Most shipping containers are 20 ft, which is the most popular. Standard containers come in a range of sizes, but this one is the smallest. Below is a chart showing shipping container sizes.
20 ft Dimensions
Inside width 7.8 ft
Inside length 19.4 ft
Tare weight 5,071.5 lbs
Internal height 7.9 ft
Payload capacity 55,126.9 lbs
It is possible to find 20 ft containers at an affordable price on the market.
Size of a 40-Foot Shipping Container
There’s twice as much height in a 40 ft container as in a 20 ft container. It’s perfect for things that don’t fit in a 20 ft container. The measurements of a 40 ft container can be found in the table below.
40 ft Container Dimensions
Inside width 7.9 ft
Inside length 39.5 ft
Inside height 7.9 ft
Payload capacity 61,200 lbs
Tare weight 2,389 cu ft
Two 20 ft containers are more expensive than one 40 ft container, because a 40 ft container costs 30% more than the 20 ft shipping container.
Sizes of High Cube Shipping Containers
High-cube containers are taller than standard containers by one foot. In high cubes, cargo is transported that is heavy, bulky, and of higher volume than standard containers can handle.
In addition to 40 ft high cube containers, 45 ft high cube containers are also available. The next section discusses their dimensions and capacities.

The examples above describe common container types. Availability depends on the equipment specification, location and booking date. Confirm the actual unit and service terms with the carrier or equipment provider.
If you need container equipment, request a written offer identifying the supplier or carrier, equipment type and condition, location, availability, charges and payment terms. Verify the contracting party and any inspection or dispute arrangements before agreeing to a purchase or lease.

Shipping Container Sizes: Which One to Choose
There are a few factors that must be considered when choosing the right container size. If you’re wondering what size shipping container to choose, here are some tips:
Cargo volume: If you are only transporting a small number of items, 20 ft containers are ideal. You should choose a container of bigger size if you have a lot of stuff.
Weight capacity: In addition to cargo volume, consider the weight of your shipment. For instance, 20 ft containers can hold 25,000 pounds of payload. If you’re shipping something heavier, a larger container is recommended.
Container cost: Container costs vary based on many factors, including the size of the container. There is a price difference between 40 ft and 20 ft containers. Nonetheless, it makes more economic sense to rent one 40 ft container instead of two 20 ft containers.
The cost of the container matters, but the equipment must also suit the goods. Temperature-sensitive cargo may require specialist equipment and an agreed operating plan.
Types and Sizes of Special Containers
Special equipment is subject to carrier or provider availability and acceptance for the specific cargo and route.

What is a Reefer?
They’re the same as dry shipping containers, with the addition of insulation and refrigerators for maintaining a specified temperature when they’re being shipped or stored.
Throughout the world, refrigerators are used to store and ship perishable goods. Intermodal transportation became possible as railroads improved, making it easier to get food across continents without affecting the nutritional value. As a result of technology, these containers are also designed better, improving their efficiency and safety.
Food can be kept fresh for a long time in refrigerators due to their lower operating temperatures. The temperature of the device is maintained at a set level (usually -10°C) using a cold-generating system. There’s usually a sliding door on one end so the container can be loaded and unloaded easily.
Container Size for Reefers
Containers that keep temperature-sensitive stuff cold are called reefer containers. Medications, pharmaceuticals, and foods fall into this category.
You can find out the dimensions of reefer containers by looking at the container size chart below.

By doing this, you can cover it or leave it open depending on your convenience. Whenever the dimensions of your cargo exceed those of a standard shipping container, open-top containers will be used.
