Compact, Affordable, and Easy to Handle
A 20 ft Conex is ideal when:
- Space is limited
- You need flexibility to move the unit between locations
- You’re storing tools, equipment, or supplies for short-term or small-to-mid-sized jobs
Its size allows it to fit in tighter areas and makes it easier to load and offload, especially for mobile job sites.

Why Choose a 40ft Conex Container?
More Room, Better Value per Square Foot
A 40-foot container is your go-to when:
- You need large-volume storage or workspace
- Cost per cubic foot matters for long-term use
- You’re planning conversions—like office spaces, workshops, or multi-unit builds
Its generous capacity makes it perfect for industrial yards, warehouses, and large-scale construction operations.

Still Not Sure What Size Conex Box Is Right For You?
One key consideration is how your needs might change over time. A 20 ft container is great for tight spaces and lighter storage, but if there’s any chance you’ll need to store more equipment or materials in the future, a 40 ft container may be the smarter long-term investment. It’s more cost-effective per square foot and gives you room to grow—whether you’re expanding operations or just want peace of mind that you’ll have enough space down the road.
