Choosing the right shipping container size comes down to matching interior space to what you actually plan to store or build. This guide covers exact dimensions for every size we stock, plus guidance on which one fits common use cases.
Shipping Container Dimensions at a Glance
These are the industry-standard (ISO) exterior and interior dimensions for the container sizes and configurations we stock. For the full reference table including door openings, see our dimensions page.
- 20ft Standard — 20′ x 8′ x 8’6″ exterior; roughly 19’4″ x 7’8″ x 7’10” interior
- 40ft Standard — 40′ x 8′ x 8’6″ exterior; roughly 39’5″ x 7’8″ x 7’10” interior
- 40ft High Cube — same footprint as a 40ft standard, but 9’6″ tall exterior for an extra foot of usable interior height
- Refrigerated (Reefer) — slightly reduced interior space due to insulation and refrigeration unit housing
20ft vs. 40ft: Which Should You Choose?
A 20ft container is the most maneuverable option — it fits comfortably in most residential driveways and side yards, and is easier to place on uneven ground. It’s the right call for personal storage, a small job-site office, or a first-time buyer testing out container use.
A 40ft container doubles your floor space for the same width and height, making it the better choice for bulk inventory, larger equipment, or any project where you’re already committing to a permanent placement. The cost per square foot of storage is usually lower with a 40ft unit than two 20ft units.
When to Choose a High Cube
The 40ft High Cube adds a full extra foot of interior height over a standard 40ft unit. That foot matters more than it sounds: it’s often the difference between fitting racking, HVAC ductwork, or tall equipment inside versus not. If you’re planning any kind of container conversion — office, workshop, or living space — the High Cube is almost always worth the modest price difference.
Matching Size to Common Uses
- Personal or residential storage — 20ft Standard
- Job-site office or tool storage — 20ft Standard or 40ft Standard depending on crew size
- Bulk inventory or warehousing overflow — 40ft Standard
- Container home, office conversion, or workshop — 40ft High Cube
- Cold storage for produce or temperature-sensitive goods — Refrigerated (Reefer)
