Choosing the right shipping container size is one of the first decisions you need to make before purchasing.
A container that is too small may leave you without enough storage space, while a container that is unnecessarily large can occupy more of your property than needed and may require additional delivery planning.
Universal Container Depot offers several container size options, including 10ft, 20ft, 30ft, 40ft, and 45ft containers.
Each size can serve a different purpose.
A 10ft container can be useful for compact storage, while a 20ft container provides a versatile general-purpose solution. A 30ft container offers an intermediate option, while 40ft and 45ft containers provide substantially more length for larger storage requirements.
In this guide, we’ll compare all five sizes so you can determine which configuration makes sense for your property and project.
For a detailed explanation of container measurements, see our Shipping Container Dimensions: Complete Size, Width, Length & Height Guide (2026).

Always confirm the specifications of the specific container before purchasing.
10ft Shipping Containers

Its smaller footprint can make it useful for properties where space is limited.
Common uses

30ft Shipping Containers
A 30ft Container sits between the 20ft and 40ft options.
This makes it useful for buyers who need more capacity than a 20ft container provides but don’t necessarily need the full length of a 40ft container.
Potential uses
- Business inventory
- Construction supplies
- Agricultural storage
- Equipment
- Larger household storage
- Commercial applications
A 30ft container can be particularly useful when property space and storage capacity need to be balanced.
Read 30ft Shipping Containers for Sale: The Complete Buyer’s Guide (2026) for a dedicated guide.
40ft Shipping Containers
A 40ft Container provides substantially more storage capacity than a 20ft container.
It can be useful for larger residential, commercial, agricultural, and industrial storage requirements.
Common uses
- Large business inventory
- Construction materials
- Machinery
- Agricultural supplies
- Furniture
- Commercial storage
- Large projects
Consider a 40ft container if:
- You need substantial storage space.
- Your property can accommodate the larger footprint.
- You have sufficient delivery access.
- You expect your storage requirements to grow
Our 20ft vs. 40ft Shipping Containers: Which Size Should You Choose? (2026) article provides a direct comparison.
45ft Shipping Containers
A 45ft Container provides even more length than a 40ft container.
This makes it appropriate for projects where additional storage capacity is needed and the property can accommodate the larger footprint.
Potential applications include:
- Large commercial inventories
- Equipment storage
- Agricultural supplies
- Industrial storage
- Large-scale projects
Because of the additional length, delivery and site preparation should be carefully planned.
See 45ft Shipping Containers for Sale: The Complete Buyer’s Guide (2026) for more information.
Which Shipping Container Size Has the Most Storage?
Among these five options, the 45ft container provides the greatest length.
The general progression is:
10ft → 20ft → 30ft → 40ft → 45ft
As length increases, storage capacity generally increases as well.
However, the largest container isn’t automatically the right choice.
Your decision should be based on:
- What you’re storing
- Available property space
- Delivery access
- Foundation requirements
- Budget
- Future storage needs
10ft vs. 20ft
The difference between 10ft and 20ft is primarily capacity versus footprint.
10ft
Best suited to smaller storage requirements and properties where space is limited.
20ft
Provides significantly more storage and is suitable for a wider range of residential and commercial applications.
If you’re unsure between these two sizes, read:
10ft vs. 20ft Shipping Containers: Which Size Is Right for You? (2026)
20ft vs. 30ft
The 30ft container provides an intermediate option.
A 20ft may be enough when your storage requirements are moderate.
A 30ft may be useful if you need additional length but don’t need the full capacity of a 40ft container.
This can be particularly relevant when your property has enough room for 30ft but limited room for a 40ft container.
30ft vs. 40ft
The difference becomes more significant as storage requirements increase.
A 30ft container can work well for medium-to-large storage requirements.
A 40ft container provides considerably more capacity for businesses, construction projects, agriculture, and large household storage.
Before choosing the larger option, make sure your property can accommodate it.
40ft vs. 45ft
Both provide substantial storage capacity.
The additional length of a 45ft container can be useful when you need maximum storage capacity among these standard length options.
However, a 45ft container also requires careful consideration of:
- Foundation size
- Delivery access
- Placement area
- Turning space
- Available property length
If a 40ft container already provides enough capacity, the additional length may not be necessary.
Standard vs. High Cube
Length isn’t the only way to increase storage capacity.
You can also consider height.
A High Cube Container provides additional height compared with a standard-height container.
This can be useful for:
- Tall equipment
- Vertical storage
- Shelving
- Business inventory
- Conversion projects
For a detailed comparison, read Standard vs. High Cube Shipping Containers: What’s the Difference? (2026).
Which Size Is Best for Home Storage?
The answer depends on how much you need to store.
Smaller household storage
Consider:
Moving or renovation storage
Consider:
Large household storage
Consider:
Very large storage requirements
Consider:
Always measure your belongings and compare them with the actual internal dimensions of the container.
Which Size Is Best for Business Storage?
Businesses should consider both current and future inventory requirements.
Small inventory
A 10ft or 20ft container may provide sufficient space.
Growing inventory
A 20ft or 30ft container may provide additional room.
Large inventory
A 40ft or 45ft container may be more appropriate.
The right choice depends on your inventory volume and how frequently you need access.
Which Size Is Best for Construction Storage?
Construction projects often require secure storage for tools, materials, and equipment.
A 20ft container can be useful for many projects.
Larger projects may benefit from 30ft, 40ft, or 45ft containers.
Consider not only storage capacity but also whether the construction site has enough room for delivery and placement.
Which Size Is Best for Agricultural Storage?
Agricultural properties may require storage for:
- Tools
- Equipment
- Machinery parts
- Supplies
- Seasonal materials
A 10ft or 20ft container can work for smaller requirements, while larger farms or operations may need 30ft, 40ft, or 45ft configurations.
How Much Property Space Do You Need?
The container itself isn’t the only thing you need to accommodate.
Your property should also allow for:
- Delivery equipment
- Access
- Door operation
- Foundation
- Maintenance
- Drainage
- Safe movement around the container
A larger container requires more careful site planning.
Before ordering, read How to Prepare Your Property for Shipping Container Delivery (2026).
Delivery Considerations by Container Size
The larger the container, the more important delivery planning becomes.
10ft
Generally requires less space, but delivery access still needs to be confirmed.
20ft
Requires moderate delivery and placement space.
30ft
Requires additional planning because of its greater length.
40ft
Requires careful route and placement planning.
45ft
Requires the most attention to available length and delivery access among these options.
For more information, read How Shipping Container Delivery Works: What Buyers Need to Know (2026).
Foundation Requirements by Size
Every container needs a suitable supporting surface.
Your foundation should account for:
- Container dimensions
- Weight
- Ground conditions
- Drainage
- Intended use
A 45ft container, for example, requires a longer prepared foundation area than a 10ft container.

New vs. Used Container Sizes
The size you choose and the condition you choose are separate decisions.
You can consider:
if economical storage is your priority.
A newer or one-trip container may be more appropriate when appearance and reduced previous use are important.

What If You Need a Specialized Container?
Size isn’t the only consideration.
Depending on your project, you may need a specialized configuration such as:
for temperature-controlled applications.
for certain cargo that requires loading from above.
for specific oversized or unusually shaped cargo.
for conversion projects.
The best container is the one that matches both the dimensions and requirements of your project.
