Width of Mobile Container Houses

Admin September 17, 2026

The width of mobile container houses varies depending on their type and specifications, with common widths ranging from 2.352 meters to 4 meters. Here is a detailed classification:

1. Width of International Standard Containers
The widely used 20-foot and 40-foot standard containers in international maritime transport have an external width of 2.438 meters (8 feet) and an internal usable width of 2.352 meters. This size is uniformly specified by the International Organization for Standardization (ISO) to ensure compatibility in global transportation. The internal width is slightly smaller than the external width, primarily due to the space occupied by the container structure (such as corner posts and insulation layers).

2. Width of Container Houses Commonly Used on Domestic Construction Sites
For temporary accommodation needs on domestic construction sites, a type of non-standard mobile container house is commonly available on the market, with an external width typically of 3 meters. These houses, through optimized structural design, offer a more spacious internal space (approximately 2.8-2.9 meters) while maintaining transportation convenience, making them suitable for multiple occupants or office use.

3. Width of Custom-Made Container Panel Houses
To meet specific scenario requirements, some manufacturers offer customized container panel houses with widths that can be extended to 3 meters or 4 meters. For example, a 4-meter-wide container panel house can be achieved by joining two standard containers or directly manufacturing an extra-wide container, suitable for scenarios with high space requirements such as exhibitions and temporary shops. However, it should be noted that extra-wide containers may face transportation restrictions (such as road width and bridge load-bearing capacity), requiring advance planning of transportation routes.

Selection Recommendations:

  • For international transportation or compatibility with standard equipment, prioritize standard containers with a width of 2.438 meters;
  • For short-term use on domestic construction sites, container houses with a width of 3 meters offer better cost-effectiveness;
  • For special scenarios requiring more space, consider customizing a 4-meter-wide container, but assess transportation feasibility.

All dimensions are measured externally, and installation and ventilation space should be reserved for actual use.
