High cube shipping containers provide additional vertical space with an external height of 9ft 6in compared to the standard 8ft 6in. This extra foot of height translates to approximately 12% additional internal volume, making high cube containers the preferred choice for applications requiring storage of tall items, increased capacity within the same footprint, or conversion projects where headroom is essential.

The high cube design has become increasingly popular as businesses and individuals recognise the value of that extra foot of vertical space. Whether you are storing bulky items that need the height, converting the container into a workspace where people will be standing, or simply want maximum capacity from your container investment, the high cube option delivers significant advantages.
High cube shipping containers maintain the same footprint dimensions as standard units while providing additional vertical space. The extra height is achieved through extended corner posts and side rails, maintaining full structural integrity and stacking capability. All other construction specifications match standard containers, including corten steel walls, marine-grade plywood flooring, and secure locking systems.
The additional volume of high cube containers offers significant practical advantages. Light, bulky cargo that would otherwise under-utilise container weight capacity can be stacked higher, improving shipping efficiency. For storage applications, the extra height accommodates taller items and enables more efficient vertical stacking of palletised goods. Conversion projects benefit enormously from the additional headroom, creating more comfortable and practical interior spaces.
