§ 01 Decision: Size ISO 668 Standards

Right Size =
Perfect Fit.

Size is the first decision: get it wrong and your equipment won't fit or you'll pay for space you don't need. A 20-foot container fits one tractor. A 40-foot holds farm equipment, workshop tools, or business inventory.

The Three Standard Sizes

Shipping containers were built for international cargo, so dimensions are standardized worldwide. A "20-foot container" is the same size whether it comes from our yard or anywhere else.

Shopping for a small shipping container? The 20ft is the smallest size we stock. Need a 10ft? We handle those as a special request, so ask us and we'll tell you what we can find for your ZIP. There's no listed price; we quote each one. Our Container Reference lists 10ft dimensions for reference.
