Practical container guide
Choose the container size around your goods and your site
Choose a 20 ft container when a compact store or smaller goods volume fits your operation and site. Consider a 40 ft container when you need more usable length or storage space and can accommodate the larger unit, its delivery and the way staff will access goods.
The decision is not simply to buy the largest box available. Measure the goods, plan the layout and compare the complete delivered cost for each size. For transport, also review the actual unit’s weight limits and the handling requirements.
A 40 ft standard container offers roughly twice the internal volume of a 20 ft standard unit, but it does not automatically double usable storage, door access or permitted cargo weight. Choose the size that works for the goods and the site.
20 ft and 40 ft: an example size comparison
| Measurement | 20 ft standard example | 40 ft standard example |
|---|---|---|
| Internal length | 5.900 m | 12.032 m |
| Internal width | 2.352 m | 2.352 m |
| Internal height | 2.395 m | 2.395 m |
| Internal volume | 33.2 m³ | 67.7 m³ |
| Door opening, width × height | 2.340 m × 2.292 m | 2.340 m × 2.292 m |
These are Hapag-Lloyd fleet examples, not guaranteed measurements for every container. Check the actual unit and distinguish standard-height equipment from high cube or other types. For a large item, the door opening can matter as much as the internal space.
When a 20 ft container may be the better fit
A 20 ft unit may suit a business with a limited storage requirement, a compact site or a stock layout that already works within the available space. Keeping the container close to the point of use can be more useful than buying extra capacity that is difficult to access.
- The stock or equipment fits with a usable retrieval route.
- Frequent access is manageable without removing unrelated goods.
- The proposed position can accommodate the unit, open doors and handling space.
- The delivery provider confirms access and placement are practical.
If compact storage is your aim, use the 20 ft container storage planning guide to sketch the shelves and working area before you select a unit.
When a 40 ft container may be worth considering
A 40 ft unit provides more length for larger stock holdings, bulky equipment or clearly defined storage zones. It may reduce the need to split compatible goods between separate stores, provided the internal arrangement remains accessible.
For example, a business with long-term stock and frequent replenishment could allocate different areas within one larger unit. The layout still needs a retrieval plan: standard end doors do not give direct access to every item along the container’s length.
Confirm that the site has space for the unit and delivery operation. Do not rely on the container’s footprint alone when planning the approach route, turning room or offloading position.
Volume and weight answer different questions
For storage, compare how the goods and shelving use the space. For a loaded container that will move, review the actual container’s marked limits, cargo weight distribution and the planned transport with the provider. More cubic capacity is not a promise that every heavier load is acceptable.
Measure individual items as well as their combined volume. A load may have a modest total volume but contain an item that cannot pass through the doors or be positioned as intended.
Compare condition and delivered cost on the same basis
Ask for the identified unit, condition, repairs and delivery scope for each size. Include transport, offloading and placement in the comparison, and keep planned modifications or site preparation visible. A larger container is useful only if its additional space supports the operation.
Do not assume that price rises in direct proportion to length. Request current quotes with matching scope. The used 20 ft container price guide explains how to separate the purchase amount from the other costs and responsibilities.
A short checklist before you choose
- List the goods, dimensions and expected storage or transport purpose.
- Draw the layout, including shelves and access space if used for storage.
- Check door openings and the actual unit’s condition and limits.
- Give the delivery provider the site location and access photographs.
- Compare complete supply-and-delivery offers for the suitable sizes.

Compare container sizes with your site in mind
Send BJH Logistics your intended use, goods dimensions, preferred location and access photographs. Discuss suitable 20 ft or 40 ft options and the delivery scope before committing.
Does a 40 ft container hold twice as much weight as a 20 ft container?
Do not assume that it does. Check the marked limits of the actual unit and the planned transport. Internal volume and permitted cargo weight are separate measurements.
Should I choose a 40 ft high cube instead of a standard container?
Consider the additional height only if it helps your goods or layout. Verify the actual dimensions, door opening, delivery clearances and condition; a taller unit does not solve every access or space constraint.
