High-Cube Shipping Container Dimensions
20ft High-Cube Container
20ft high-cube containers are perfect for storage applications where height matters but space is limited, portable offices with comfortable ceiling heights, and small retail stores requiring extra vertical display area. The 20ft high-cube container balances a compact footprint with generous internal volume.
40ft High-Cube Container
40ft high-cube containers are ideal for bulk storage operations, modular building conversions requiring substantial floor space, international shipping of oversized cargo, and large-scale commercial applications where maximum volume is essential.
Popular Uses for High-Cube Containers
Domestic & International Shipping
High-cube shipping containers excel at loading and transporting general cargo that would be constrained in standard-height containers. The extra height accommodates larger machinery and stacked pallets with greater clearance.
Storage Solutions
The additional height is suitable for storing different types of equipment, inventory, and furniture. The extra space allows for improved organisation, taller shelving systems, and more efficient vertical storage.
Container Homes and Conversions
The extra foot of height adds valuable headroom for modified container living spaces, creating more spaciousness and comfort. It allows for raised flooring, ceiling insulation, and overhead utilities.
Event and Exhibition Spaces
Modified high-cube containers work perfectly for pop-up retail stores, festival booths, and restaurants. The extra height enhances visitor comfort and allows for more impressive interior displays.
Agricultural and Rural Storage
Ideal for hay storage, machinery protection, and feed storage, our secure high-cube shipping containers accommodate larger materials and allow for better ventilation systems in agricultural applications.
On-Site Offices
Suitable for temporary workspaces, these containers offer more comfortable ceiling heights while maintaining durability and security for construction sites and mobile businesses.
Customer Testimonials
What is a High-Cube Container
High-cube containers are specialised shipping containers that provide approximately 30cm or an extra foot of height over standard containers while maintaining the same length and width dimensions. This additional vertical space creates numerous advantages for both shipping and storage applications.
The key difference between high-cube and standard containers lies in their internal height. While standard containers typically offer 2.4m of internal height, high-cube containers provide approximately 2.7m. This seemingly small difference creates approximately 13% more cubic capacity, making a significant impact on storage potential and comfort for converted spaces like retail stores and restaurants.
High-Cube Shipping Container Modifications

Custom Paint & Branding
Elevate your commercial presence with professional painting and branding, turning functional storage into powerful marketing assets.
Regulations and Compliance
Container Safety Convention (CSC) certification ensures structural integrity and safe transportation. All our high-cube containers meet these international standards, providing peace of mind for shipping applications.
High-Cube Container Buying Guide
New vs Used
New containers offer pristine condition and maximum lifespan, ideal for sensitive storage or premium conversions. Used containers provide excellent value, with B-grade and C-grade options available.
Choosing the Right Size
Assess your space requirements carefully, considering not just current needs but future expansion. Remember that while 40ft containers offer more space, they require larger delivery vehicles and more substantial site preparation.
