Understanding Shipping Container Sizes in Feet
Shipping containers are a familiar sight at ports, construction sites, and even in creative housing projects. If you’re interested in renting, purchasing, or repurposing one, knowing the common container sizes—in feet—is essential. This guide breaks down shipping container dimensions, explains the differences among popular sizes, and shares practical advice for choosing and using containers effectively.
Common Shipping Container Sizes
Shipping containers come in several standard sizes measured in feet. The most widely used sizes include:
- 10-foot container
- 20-foot container
- 40-foot container
- 45-foot container
Let’s explore each size and their typical uses.
1. 10-Foot Shipping Containers
Ideal For: Short-term site storage, residential use, small jobs, or locations with space limitations.
Dimensions:
- Exterior Length: 10 ft
- Exterior Width: 8 ft
- Exterior Height: 8.5 ft (standard), 9.5 ft (high cube)
- Interior Length: ~9.3 ft
- Interior Width: ~7.7 ft
- Interior Height: ~7.8 ft (standard), ~8.8 ft (high cube)
Benefits:
- Easy to fit in tight spaces (like urban driveways or small job sites)
- Can be moved with smaller trucks or forklifts
Challenges:
- Reduced storage capacity
- Less common, so may cost more per cubic foot compared to larger containers
2. 20-Foot Shipping Containers
Ideal For: Moving household goods, small construction projects, storing retail inventory, or converting into small offices or pop-up shops.
Dimensions:
- Exterior Length: 20 ft
- Exterior Width: 8 ft
- Exterior Height: 8.5 ft (standard), 9.5 ft (high cube)
- Interior Length: ~19.4 ft
- Interior Width: ~7.7 ft
- Interior Height: ~7.8 ft (standard), ~8.8 ft (high cube)
Benefits:
- Most cost-efficient for smaller loads
- Easier to transport and position than 40-foot containers
- Often available in ‘one trip’ (nearly new) or ‘used’ conditions
Challenges:
- May be too small for bigger storage needs
3. 40-Foot Shipping Containers
Ideal For: Commercial transport, long-term storage, container homes, modular buildings, or large jobs.
Dimensions:
- Exterior Length: 40 ft
- Exterior Width: 8 ft
- Exterior Height: 8.5 ft (standard), 9.5 ft (high cube)
- Interior Length: ~39.5 ft
- Interior Width: ~7.7 ft
- Interior Height: ~7.8 ft (standard), ~8.8 ft (high cube)
Benefits:
- Doubles the capacity of 20-ft containers for only a modest price increase
- Most popular size for overseas shipping
- High cube options give extra vertical storage
Challenges:
- Requires more space to transport and place
- Some delivery sites may be too small to accommodate
4. 45-Foot Shipping Containers
Ideal For: Specialized commercial and industrial uses, large-scale modular construction, or projects needing maximum space in a single container.
Dimensions:
- Exterior Length: 45 ft
- Exterior Width: 8 ft
- Exterior Height: 9.5 ft (high cube)
- Interior Length: ~44.5 ft
- Interior Width: ~7.7 ft
- Interior Height: ~8.8 ft
Benefits:
- Largest available standard size
- Greater load capacity
- High cube design offers increased usable height
Challenges:
- Heaviest and longest to handle
- May require special permits or transportation arrangements
- More expensive to purchase and deliver
High Cube vs Standard Height Containers
Shipping containers are most commonly offered in two heights:
- Standard Height: 8 ft 6 in tall on the outside
- High Cube: 9 ft 6 in tall on the outside (adds an extra foot of vertical space)
When should you choose a high cube container?
- When storing or shipping taller items (like equipment or stacked goods)
- If you’re planning a container conversion (such as homes or offices) for extra headroom
- When every extra cubic foot counts in your storage planning
Practical Tips for Choosing the Right Container Size
Selecting the most suitable container involves more than just picking the largest you can afford. Here’s how to approach your decision:
1. Assess Your Space & Access
- Measure the available area where you wish to deliver or store your container.
- For tight spots, consider a 10- or 20-foot container. Ensure there’s enough clearance for delivery trucks (typically need at least 60 feet of straight access for 40-foot containers).
- Ask about the ground support—containers require a level, solid base.
2. Calculate Your Storage Needs
- Inventory what you’ll be storing. 20-foot containers hold the contents of a one- to two-bedroom apartment. 40-foot containers can fit a three- to four-bedroom house.
- If you’re uncertain, it’s usually less costly to pay for a larger container upfront than to rent a second one later.
3. Plan for Container Handling
- Larger containers are harder to move and position.
- Delivery trucks require more space and may need room to turn around.
- Think about how you’ll load/unload—standard containers have doors at one end, but some specialty containers have doors at both ends or along the side.
4. Consider High Cube Options
- High cubes provide valuable extra space for slightly more cost.
- Perfect for oversized items, tall shelving, or if you need good headroom for working inside the container.
5. Factor in Condition and Intended Use
- One Trip (Newer): Almost new, but cost more
- Cargo Worthy: Used but in good condition, suitable for shipping
- Wind and Watertight: Best for storage, not recommended for international shipping
Specialized Containers & Modifications
In addition to standard rectangular containers, there are specialty models:
- Open Top Containers: For heavy or awkward cargo loaded by crane
- Reefer (Refrigerated) Containers: For perishable goods
- Double Door or Tunnel Containers: Doors at both ends for easy loading/unloading
- Side Opening Containers: For rapid side access
Modifications like windows, doors, insulation, or shelving are common for construction, retail, or residential use.
Cost Tips: Shipping From/To
Shipping container costs depend on:
- Size and type (larger and specialized containers cost more)
- Condition (new/one trip costs significantly more than used)
- Delivery distance (longer or difficult deliveries increase cost)
- Local supply and demand
Cost-Saving Tips:
- Compare multiple suppliers for the best rate.
- Consider a used container if looks aren’t a top priority.
- Plan your delivery location—difficult sites can add delivery charges.
- Ask about “one-trip” containers for a balance between quality and value.
- If shipping overseas, make sure your container is “cargo worthy” and certified.
Benefits of Standardized Container Sizes
Shipping containers owe much of their global popularity to standardized sizing:
- Seamless Transport: Containers fit on ships, trains, and trucks worldwide
- Predictable Capacity: Shippers and buyers can easily calculate space and cost
- Easy Resale and Repurposing: Universal sizes make resale and modifications simple
- Efficient Stacking: Containers stack securely for storage or modular construction
Common Challenges and How to Overcome Them
- Site Access: Make sure trucks can reach and position the container where you need it. Tree branches, low wires, or tight corners can pose issues.
- Permits: Some cities require permits to place a container, especially for residential or commercial use outside shipping yards.
- Moisture and Ventilation: Containers are airtight; for long-term storage, install vents or use moisture absorbers to prevent dampness.
- Security: Doors should have lock boxes or other theft deterrents, especially if kept offsite or in visible areas.
- Weight Limits: Respect the maximum weight and load capacity, especially if you plan to move a fully loaded container.
Best Practices For Buying or Renting Shipping Containers
- Inspect in Person: When possible, check for rust, door function, and water tightness.
- Request Photos: If buying remotely, ask for current images inside and out.
- Check Certifications: Especially for international shipping (look for a valid CSC plate).
- Understand Terms: Clarify delivery, return, and damage policies when renting.
- Plan For Removal: Know how and when you’ll remove the container after use.
Conclusion
Knowing the standard shipping container sizes in feet is the first step to making the right choice for storage, transport, or creative projects. Ten-foot, twenty-foot, forty-foot, and forty-five-foot containers each suit different needs, budgets, and sites. By understanding dimensions, features, and logistical considerations, you can maximize value and avoid common pitfalls.
