What Is a 20 Ft Storage Container?
A 20 ft storage container is a standardized intermodal shipping container originally designed for ocean freight but now widely used for on-land storage. Measuring approximately 20 feet in length, these units are constructed from high-grade Corten steel, making them corrosion-resistant and built to last decades.
Unlike traditional sheds or garages, a 20 ft storage container is portable, stackable, and can be delivered directly to your location. It’s an ideal solution for anyone needing extra space without the hassle of permanent construction. Homeowners use them for seasonal items, tools, or vehicles, while businesses rely on them for inventory overflow, equipment storage, or even temporary offices.

The 20 ft storage container comes in two main height options: standard (8’6″) and high-cube (9’6″), giving you flexibility based on your storage volume requirements.
Dimensions and Specifications of a 20 Ft Storage Container
Understanding the exact measurements is crucial when planning your storage setup. Here are the standard specs for a typical 20 ft storage container:
- Exterior Dimensions: 20 ft long x 8 ft wide x 8 ft 6 in high (standard) or 9 ft 6 in high (high-cube)
- Interior Dimensions: Approximately 19 ft 4 in long x 7 ft 8 in wide x 7 ft 10 in high (standard) or 8 ft 10 in high (high-cube)
- Door Opening: 7 ft 8 in wide x 7 ft 5 in high (standard) or 8 ft 5 in high (high-cube)

- Empty Weight (Tare): Around 4,850–5,300 lbs
- Maximum Gross Weight: Up to 67,200 lbs
These precise dimensions make the 20 ft storage container compact enough for residential driveways yet spacious enough for commercial use.
