Shipping Container Types and Sizes: Complete Guide for Global Trade
Shipping containers are the backbone of international logistics. They make it possible to move goods safely and efficiently across oceans, roads, and railways. With different shipping container types and sizes, almost any cargo can be transported—from machinery and vehicles to food, chemicals, and bulk commodities.
In this guide, we’ll explore the most common shipping container types, standard sizes like 20ft and 40ft, and specialized containers designed for unique cargo.
Why Shipping Containers Are Essential
The global supply chain depends on standardized containers because they:
- Protect cargo – goods are enclosed and secure.
- Save time – easy loading and unloading with cranes and forklifts.
- Ensure compatibility – ISO standards mean containers fit ships, trucks, and ports worldwide.
- Offer flexibility – different types for dry goods, refrigerated cargo, oversized machinery, or liquids.
Standard Shipping Container Sizes
The most common container sizes are the 20ft and 40ft containers. To simplify ship capacity, the industry uses TEU (Twenty-foot Equivalent Unit):
1 TEU = One 20ft container
1 FEU = One 40ft container (equal to 2 TEUs)
This helps shipping lines measure how many containers a vessel can carry.
20ft Container
- Dimensions: Approx. 6m long × 2.4m wide × 2.6m high
- Volume: Around 33 cubic meters
- Max cargo weight: ~25 tons
- Best for: Heavy cargo like steel, machinery, and raw materials.
40ft Container
- Dimensions: Approx. 12m long × 2.4m wide × 2.6m high
- Volume: Around 67 cubic meters
- Best for: Bulky cargo like furniture, electronics, or textiles.
High Cube Containers
A High Cube container is similar to a standard container but adds 1ft (30cm) in height. This makes them ideal for light but voluminous cargo.
- Most common: 40ft High Cube
- Also available: 45ft, 48ft, 53ft (mainly in North America)
- Dimensions (40ft HC): Approx. 12m × 2.4m × 2.9
Less Common Container Sizes
Not all shipments use 20ft or 40ft containers. Some special sizes include:
- 10ft Container – Compact, similar to a garden shed; used for small cargo or storage.
- 45ft High Cube – Extra-long container with corner castings to stack with 40ft units.
- 48ft and 53ft Containers – Extra-large, mainly used in domestic U.S. transport.
Shipping Container Types
Now let’s explore the main shipping container types used in international logistics. Each type is designed for specific cargo requirements.
1. Dry Container (General Purpose)
- Most widely used type.
- Fully enclosed and weatherproof.
- Suitable for electronics, packaged goods, textiles, and machinery.
2. Reefer Container (Refrigerated)
- Functions as a mobile refrigerator.
- Maintains temperatures from –30°C to +30°C.
- Commonly used for perishable goods like meat, seafood, fruits, vegetables, and medicines.
3. Insulated Container
- Similar to reefers but with added insulation.
- Equipped with heating/cooling compressors.
- Used for temperature-sensitive products like blood, organs, and specialty chemicals.
4. Open Top Container
- No fixed roof; instead, it uses removable covers.
- Designed for tall or oversized cargo such as large machinery.
- Loading is done with cranes from above.
5. Flat Rack Container
- Collapsible sides or no sides/roof at all.
- Ideal for oversized machinery, vehicles, or construction materials.
- Provides easy access for loading heavy cargo.
6. Tank Container (ISO Tank)
- Made of anti-corrosive steel.
- Designed for liquids such as wine, chemicals, and oils.
- Must be filled between 80% and 95% for safety.
7. Bulk Container
- Specially designed for dry bulk goods.
- Commonly used for grains, coffee beans, animal feed, and spices.
- Can also carry general cargo when required.
8. Ventilated Container
- Built with ventilation to reduce moisture buildup.
- Used for goods like cocoa beans, coffee, and other organic cargo.
Choosing the Right Shipping Container Type
When selecting a container, consider:
- Cargo type – Dry, refrigerated, liquid, bulk, or oversized.
- Weight vs volume – 20ft is better for heavy cargo; 40ft for lighter, bulky cargo.
- Special requirements – Temperature control, ventilation, or extra space.
- Regional availability – Sizes like 48ft and 53ft are common in the U.S. but rare elsewhere.
Choosing the correct container saves costs, ensures safety, and prevents delays.
