ISO/CSC Shipping and storage containers
Length: Almost all containers are 20' or 40' (6m/12m) with very few 10' (3m), 30' (9m) and 45' (13.6m)
Width: 8' (2.45m) is standard though in Europe there are a few that are pallet width = 2.50m
Height: Standard 8'6" (2.59m) and High Cube 9'6" (2.90m) are normal
Storage containers (normally without CSC)
There are smaller sizes than 10' (3m) and these typically have lower heights and widths than ISO standard dimensions
There are also non-ISO lengths between 10' and 40' featuring ISO standard heights/widths
USA domestic containers
Dimensions of these are suited to US intermmodal regulations. These containers are too long for use in EU
