How to use this
Every box here is drawn to the same scale from external dimensions, corner-aligned so you can see the size difference directly rather than guessing from a spec sheet. The most common comparison is 20ft Standard vs. 40ft Standard — if that's your decision, read our full breakdown in 20ft vs. 40ft Containers: How to Pick the Right Size. For current market pricing on any of these sizes, see Shipping Container Prices in 2026.
Door opening height matters more than most buyers expect — a High Cube's extra 12in of ceiling height doesn't help if you're loading a forklift through a Standard-height door on a connecting unit. Reefer containers show smaller internal dimensions than dry containers of the same external size because of the insulation and refrigeration unit built into the walls and one end.
