Searching for a 40 ft conex box, a 40 conex container or a 40-foot shipping container? They’re all the same standard size: 40 feet long and 8 feet wide, 8′ 6″ tall as standard or 9′ 6″ as a high cube.

- Bulk overflow stock for a warehouse or retailer
Delivery and site space
A 40ft container needs much more room to deliver than a 20ft. The tilt-bed truck needs a long, straight, level approach, plus clear space overhead. Measure your site before you choose, and describe it when you request a quote so we can confirm access.
Standard or high cube 40ft?
The 40ft high cube adds a foot of height for about 12% more space. It’s the usual choice for container homes, offices and racking. For straightforward storage, the 40ft standard container costs less.
New, used or rented
Choose new (one-trip) for conversions and appearance, used to save on storage, or rent or rent-to-own to spread the cost.
