About the 20ft high cube conex box
A high cube container is built like a standard unit but stands a foot taller, at 9′ 6″ instead of 8′ 6″. That extra headroom adds roughly 12% more interior volume without taking up any more ground space.
The added height makes it the favorite for conversions such as offices, workshops, and container homes, because there’s room for insulation, lighting, and ceiling finishes while still leaving comfortable standing room.
Why 20ft?
The most popular size we sell. It balances space, cost, and easy delivery, and fits on most residential and commercial sites.
What fits
About the contents of a one- to two-bedroom home, or roughly 10 standard pallets.
Who buys a 20ft high cube conex box?
Best for: workshops and site offices where you’ll insulate the ceiling and still want comfortable headroom; tall equipment, pallet racking or stacked goods; container cabins and studios; and pop-up shops that need a taller door opening.
The extra foot costs a little more than a standard box and can matter for height limits, gates or HOA rules, so check before you choose. Compare it with the 20ft standard container. For a bigger footprint with the same height, see the 40ft high cube.

Is a 20ft high cube worth the extra cost?
