When considering the best options to deliver sensitive cargo across long distances, choosing the 40′ reefer container dimensions is a sound decision because of the container type’s many benefits.
With ample container interior space perfect in most situations, 40′ reefer container dimensions are the suitable companion for cargo with a bulky nature or considerable length that needs the best platforms.

Why 40′ Reefer Containers Over Other Sizes?
As the workhorse of cold chain logistics, how does the 40-foot reefer outshine both its smaller and larger counterparts in several ways?
Space
First, it provides twice the space of a 20-foot reefer at a much better price per cubic meter, making it ideal for high-volume shipments without doubling your shipping costs.
What’s more, this size is perfect for businesses that need to move large quantities of perishable goods, like seafood, meat, dairy, and pharmaceuticals across continents.
Capacity
Unlike smaller reefers, the 40-foot model can fit up to 21 standard pallets or 25 Euro-pallets in a single layer. It means more goods per trip, fewer shipments, and better freight rates!
Rather than the 45- or 53-foot reefers, the 40-foot container is more universally accepted in global shipping networks because of its standardized dimensions and size.
Features
Modern 40-foot reefers also have advanced cooling technology that maintains precise temperature ranges (from -30°C to +30°C or even as low as -40°C in some models).
Many models now feature smart tracking and IoT sensors for real-time temperature and location monitoring, meaning you can monitor your cargo more easily than ever before.
Specifications
Dimensions
The 40-foot reefer container follows strict ISO standards, but there are small variations depending on the manufacturer and specific model.
To give you an idea of what the container looks like, here are the general specifications:
External Dimensions
- Length: 12.19 m (40 ft)
- Width: 2.44 m (8 ft)
- Height: 2.59 m (8 ft 6 in)
Internal Dimensions
- Length: 11.56 m (37 ft 11 in)
- Width: 2.29 m (7 ft 6 in)
- Height: 2.25 m (7 ft 5 in)
Door Opening
- Width: 2.29 m (7 ft 6 in)
- Height: 2.26 m (7 ft 5 in)
Weight Dimensions
- Tare Weight: 4,800 kg (10,582 lbs)
- Payload Capacity: 27,700 kg (61,068 lbs)
- Maximum Gross Weight: 32,500 kg (71,650 lbs)
CBM
CBM, or cubic meter capacity, is a crucial piece of information for shippers who need to maximize every bit of the reefer container’s internal space.
In this context, a 40-foot reefer offers between 59.8 m³ and 67.7 m³ of usable volume, depending on the model and whether it’s a standard or high-cube version.
Nonetheless, you can expect both reefer container variants to have the following CBM specifications:
- Standard 40-foot reefer: ~59.8 m³ (2,112 ft³)
- High-cube 40-foot reefer: Up to 67.7 m³ (2,390 ft³)
The high-cube version adds about a foot of extra height, which can make a big difference for lighter, bulkier cargo or when stacking pallets.
With the extra height, the container is enough to handle large shipments of boxed or palletized goods, making it a favorite for exporters of fresh produce, meat, seafood, and pharmaceuticals.
CBM is also important when calculating shipping costs, as many freight rates are based on the volume of your cargo. By knowing the CBM value, you can avoid any potential overspending during shipments.
Reefer Machine Types
The refrigeration unit is the heart of any reefer container. Modern 40-foot reefers come with several machine options, each suited for different cargo and operational requirements:
Standard Single-Temperature Units
These are the most common and can maintain a set temperature anywhere from -30°C to +30°C. They’re perfect for most perishable goods, from frozen food to chilled fruits.
Dual Temperature Units
Some 40-foot reefers offer dual zones, allowing you to transport products with different temperature needs in the same container.
For example, you can keep frozen seafood in one section and fresh produce in another, each at its ideal temperature. With this benefit, you don’t have to worry about storing them at the same temperature level.
High-Cube and Pallet-Wide Units
High-cube reefers provide extra vertical space, while pallet-wide versions are designed to fit more standard pallets, improving loading efficiency and reducing product damage.
Energy-Efficient and Smart Units
Modern machines often feature energy-saving technologies, such as improved insulation and variable-speed compressors. IoT-enabled units allow for real-time monitoring and remote adjustments, ensuring cargo safety and regulatory compliance.
Power Supply
Most 40-foot reefers can run on a 3-phase power supply (220V, 380V, 400V, 440V, or 480V at 50/60Hz), making them compatible with global energy infrastructure.
Some reefer units also come with humidity control, air exchange systems, and alarms for temperature deviations so that sensitive cargo stays in perfect condition throughout the journey.
Suitable Cargo Types
The versatility of a 40-foot reefer container means you can ship a wide range of temperature-sensitive products:
Fresh Produce
Fruits, vegetables, and herbs that stay crisp and fresh thanks to precise humidity and temperature control.
Meat and Seafood
Frozen or chilled, these high-value goods require reliable cold storage to prevent spoilage and maintain quality until they’re ready for mass consumption.
Dairy Products
Milk, cheese, and yogurt need stable, cool temperatures during transit, so their quality will remain consistent and safe for consumption by consumers.
Pharmaceuticals and Healthcare Products
Vaccines, medicines, and other sensitive items demand strict temperature regulation and monitoring, features that reefer containers can provide to these products.
Specialty Foods
Chocolate, wine, and other gourmet items are sensitive to heat or cold, making reefer containers the only suitable platform to deliver them to distant locations.
Biochemical and Lab Samples
Some reefers are used for scientific or industrial shipments that require a controlled environment so that their structural integrity won’t deteriorate from unwanted temperature levels.
Frozen Bakery Goods and Ice Cream
These products need ultra-low temperatures, which modern refrigerators easily provide, especially those of the reefer machine variants in reefer containers.
Ready-to-Eat Meals and Packaged Foods
Ideal for large-scale catering or military logistics that need some space to keep them at a cold temperature during on-site events or military assignments.
