What Size Storage Container Do I Need?
The short answer: a 20 foot container is the workhorse for most job sites, holding tools, materials, and equipment for a typical crew. A 40 foot container roughly doubles the space for larger sites or long projects, and a 10 foot container suits tight sites and small tool and material storage. Choose based on what you are storing, how long, and how much room the site has.
Storage containers are weatherproof, lockable steel units used to secure tools, materials, and equipment on site. Here is how the sizes compare.
Storage container sizes at a glance
| Size | Dimensions (L x W x H) | Floor space | Best for |
|---|---|---|---|
| 10 ft | 10 x 8 x 8.5 ft | ~80 sq ft | Tight sites, small tool and material storage, secure lockup |
| 20 ft | 20 x 8 x 8.5 ft | ~160 sq ft | The standard job site container: tools, materials, and equipment for a typical crew |
| 40 ft | 40 x 8 x 8.5 ft | ~320 sq ft | Larger sites, long projects, bulk material and equipment storage |
Standard containers are 8 feet 6 inches tall. High-cube 40 foot units add about a foot of interior height for taller equipment. All are 8 feet wide, so plan placement and delivery access.
What size container for tools and a small crew?
A 20 foot container fits most single-crew job sites, with room for hand and power tools, fasteners, and general materials, plus space to move inside. If you only need a secure lockup for tools on a tight site, a 10 foot container is enough and takes less room.
What size container for a large or long project?
A 40 foot container is the call for larger sites, longer projects, or when you are staging bulk materials and larger equipment. Two 20 foot containers can be more flexible than one 40 foot if you want storage in more than one location on a big site.
What to consider before you order
- What you are storing: tools and small materials fit a 10 or 20, bulk materials and equipment lean 40.
- How long: longer projects justify more space so you are not reorganizing constantly.
- Site access: a 40 foot container needs clear, level ground and room for a delivery truck to place it.
- Security and climate: all units are lockable steel, ask about extra security hardware and shelving.

Frequently asked questions
What size storage container do I need for a job site?
A 20 foot container is the standard for most job sites, holding tools, materials, and equipment for a typical crew. Use a 10 foot for tight sites and small storage, and a 40 foot for larger sites, long projects, or bulk material and equipment.
What are the dimensions of a 20 and 40 foot container?
A 20 foot container is about 20 by 8 by 8.5 feet with roughly 160 square feet of floor space, and a 40 foot is about 40 by 8 by 8.5 feet with roughly 320 square feet. High-cube 40 foot units add about a foot of interior height.
How much can a 20 foot storage container hold?
A 20 foot container gives about 160 square feet of secure, weatherproof floor space, enough for the tools, materials, and equipment of a typical single crew with room to move inside.
Should I get one 40 foot or two 20 foot containers?
One 40 foot gives the most space in a single unit. Two 20 foot containers can be more flexible on a large site, letting you place secure storage in more than one location closer to the work.
What do I need for delivery?
Clear, level ground and room for a delivery truck to place the container. A 40 foot unit needs more clearance than a 10 or 20, so confirm access and placement before delivery.
