10ft, 20ft, 40ft or High Cube: choose a format
Choose the format from the goods and site. Additional capacity helps only when the container can be delivered, loaded and used as intended.

Choose length from the inventory
A 10ft unit can suit a constrained footprint but still needs delivery access. Confirm purpose-built or cut-down construction; shipping suitability and details may differ.
A 20ft unit offers a shorter footprint than a 40ft container. The longer unit provides more floor length but needs a suitable delivery plan. Identify separate floor positions, stackable goods and items needing regular access before choosing.
Use the right measurement for each decision
Nominal names such as 20ft and 40ft identify formats. Use actual model dimensions for the site, goods and loading route. The model examples below belong to the existing reference dataset; the supplier must confirm the unit being offered.
| Measurement | Decision it supports | Separate check |
|---|---|---|
| Outside length, width and height | Footprint, delivery and overall placement | Vehicle space, unloading and surrounding access |
| Clear interior | Packed goods, lining or finished layout | Usable arrangement and retrieval space |
| Door opening | Packed load entering the unit | Approach, threshold and handling method |
| Tare, payload and gross limit | Mass assessment for the actual unit | Floor loads, lifting and route constraints |
Compare reference dry-container dimensions
Lengths below are clear internal lengths; openings are width × height. Different manufacturers, equipment and condition can change usable dimensions. These are dry-container examples, not reefer or completed-conversion specifications.
| Reference model | Internal length | Door opening |
|---|---|---|
| 20ft standard | 19 ft 4.3 in | 7 ft 8.1 in × 7 ft 6.2 in |
| 40ft standard | 39 ft 5.7 in | 7 ft 8.1 in × 7 ft 6.2 in |
| 40ft high cube | 39 ft 5.7 in | 7 ft 8.1 in × 8 ft 6.2 in |
Compare standard height and High Cube
Common external heights are 8ft 6in for standard and 9ft 6in for High Cube. Confirm the offered unit’s actual internal and door dimensions. Floor, wall and ceiling build-ups reduce finished space.
Extra height does not establish safe stacking or building compliance. Confirm the vehicle-plus-load route height and the final position with the carrier; provincial or territorial vehicle-dimension rules and route restrictions can apply.
Choose access for the working routine
End doors suit many storage uses. Side access can help with long or frequently handled loads, but the mechanism, opening and structure must match the project. Compare the actual specification rather than the product name.
Use reference dimension tools for an initial check, then obtain supplier confirmation of the proposed unit, handling method and delivery conditions. Compare equivalent condition and delivered scope in CAD.
Compare two shorter units with one longer unit
Two 20ft units can separate goods or place doors in different locations, but they also create separate deliveries or handling operations, supports and access routes. One 40ft unit provides a continuous interior; a long rigid item may rule out splitting the storage between shorter units.
High Cube adds height rather than floor length. It does not automatically add pallet floor positions or permit heavier or taller stacking. Compare the actual load, door opening, delivery route and proposed finished use.
- Start with the longest rigid item and the loaded mass, not only total volume.
- Check door entry and retrieval access for the items needed most often.
- Confirm actual dimensions, condition and required opening arrangement.
- Request equivalent totals including equipment, delivery, unloading and applicable taxes.
Questions before you choose
Will two 20ft units always replace one 40ft unit?
No. Door access, separation, supports, delivery, permissions and the goods can make the two arrangements very different.
Does High Cube provide more floor space?
The extra height does not itself increase floor length or width. Compare the actual model and the intended stacking or finished layout.
Is a 10ft unit automatically easier to deliver?
Its footprint is shorter, but the delivery vehicle and unloading method still need enough access and working space. Obtain the carrier's plan for the actual site.
