Planning a container build or transport project? Understanding external container dimensions is essential. This guide covers the standard sizes for 10ft, 20ft, and 40ft shipping containers — including both standard (GP) and high cube (HC) formats. Whether you’re designing a home, studio, or storage solution, knowing the precise measurements ensures a smoother design and construction process. Use the tables below to compare internal space, external clearances, and weight capacities across each container type.
