Shipping Container Dimensions & Sizes (UK Guide)

Shipping Container Dimensions Explained

Choosing the correct shipping container size is essential whether you’re looking to hire, buy or convert a shipping container. External footprint, internal space and container height all affect whether a container is suitable for your site, access requirements and intended use.

This guide provides clear, accurate shipping container dimensions in both metric and imperial measurements, allowing you to compare sizes easily and choose the right container for your project.

  • External dimensions show the overall footprint of the container and are essential for site planning, transport and access.
  • Internal dimensions show the usable space inside the container and are particularly important for storage layouts and container conversions.

Container height is available in two main formats:

High cube containers are commonly selected for workshops, plant rooms and conversion projects where extra height is beneficial.

  • Dimensions may vary slightly depending on the container manufacturer
  • Internal measurements will be reduced if a container is insulated or converted
  • Refrigerated (reefer) or insulated containers have smaller internal dimensions than standard containers

If your project has specific space or access requirements, we recommend speaking with our team before ordering.
