    Shipping container sizes


    Shipping container sizes

    Here at Gap Containers, we’re committed to providing the best possible service for our customers. Our goal is to ensure you identify the ideal container size for your needs. And to help with your purchase, here we’ve created a detailed conversion chart for some of the main shipping container sizes.

    These include 20ft container dimensions and 40ft container dimensions – which tend to be the most popular – as well as dimensions for 10ft and 30ft structures. External and internal measurements are listed in both imperial and metric units and given for both standard and high cube containers.

    Please note, the container dimensions provided are as accurate as possible – but they are just an approximate indication. The exact size of a container can vary depending on the manufacturer. Therefore, it’s important to use these measurements as a guide only.

    If you’d like further guidance on which container size is best for you, please don’t hesitate to contact our team. Either give us a call on 0870 240 9405 or send an email to We’re always happy to help and, after a quick chat, we’ll be able to point you in the right direction.


    Standard external container dimensions


    Shipping container dimensions

    Shipping container dimensions are standardised for shipping purposes. They can be of different lengths and heights. But to conform with ISO regulations, they must be 8ft (2.44m) wide – allowing them to be stacked together safely onboard cargo vessels, cranes, and other modes of transport.

    Here we detail the standard length, width and height of the four most popular container sizes:

    Imperial measurements

    Container Length 10ft 20ft 30ft 40ft
    Container Width 8ft 8ft 8ft 8ft

    » High cube 2.89m 2.89m 2.89m 2.89m

    Standard internal container dimensions

    All of our shipping containers are made from corrugated steel. This corrugation has a depth of around 1 inch (25mm) and, therefore, slightly affects the internal width and length of the structure.

    The doors and floor of the container also impact its interior measurements. And although they don’t make a huge difference, it’s still worth taking this into account when selecting the ideal container dimensions for your needs.

    Here we list the internal length, width, height, end door aperture width and height, floor area, cubic capacity, and weight of the four most popular container sizes (10ft, 20ft, 30ft, and 40ft).
