What fits in a 20ft container?
- About 10 standard pallets (48″ × 40″) in a single layer
- The contents of a one- to two-bedroom home
- A car or small truck (check its width against the 7′ 8″ door opening)

Delivery and site space
A 20ft container usually arrives on a tilt-bed truck that slides it onto the ground. Plan for a firm, level spot, a long straight approach for the truck, and clear space overhead with no wires or branches. Share your ZIP code and a description of your site when you request a quote, and we’ll confirm access.
New or used 20ft?
New (one-trip) 20ft containers suit offices, workshops and anywhere appearance matters. Used 20ft containers cost less and are graded: cargo-worthy units can still ship overseas, while wind and watertight units are sold for storage. Read more about used conex containers and new conex containers.
Buy, rent or rent-to-own
Every 20ft type can be bought outright, and most can be rented or bought on a rent-to-own plan. See conex rental and rent-to-own, or the conex price guide for what goes into a quote.
