The short answer
Choose a 20ft if space or access is tight, you need a single shop or office, or you're on a smaller budget. Choose a 40ft (or 40ft High Cube) if you need maximum storage or floor space — it usually costs less per square metre.
Side by side
| 20ft | 40ft | |
|---|---|---|
| Floor area | ≈ 14 m² | ≈ 28 m² |
| Volume | ≈ 33 m³ | ≈ 67 m³ (76 m³ High Cube) |
| Delivery access | Fits most compounds and estates | Needs a long, clear approach |
| Best for | Shops, kiosks, site offices, small storage | Warehousing, large stores, multi-room conversions |
| Cost per m² | Higher | Lower |
Things people forget
- Delivery is the deciding factor more often than budget. Measure your gate and the route to the spot before choosing a 40ft.
- Two 20ft units are more flexible than one 40ft — you can place them separately or side by side — but cost more in total.
- For conversions, height matters. A standard 8′6″ container loses headroom quickly once you add insulation and a ceiling; a High Cube avoids that.
Frequently asked questions
Is a 40ft container twice the price of a 20ft?
Usually less than twice. Compare the live prices shown on this page — a 40ft generally gives more space per naira.
Can a 20ft container be delivered in Lagos estates?
In most cases yes, provided the truck can reach the spot. Check gate width, overhead cables and the ground before delivery day.
