Shipping Container Sizes & Dimensions: 20ft and 40ft Guide - Four Sons Logistics

When exploring shipping containers for sale, it’s important to understand the range of available sizes and how each option fits different storage or transportation needs. Containers come in standard and high cube designs, with popular choices such as the 20ft shipping container and 40ft shipping container. Knowing the differences in dimensions and capacity allows you to choose a container that aligns with your project’s specific needs.

Shipping containers are built for durability and adaptability. They are engineered to store or transport various types of cargo and are offered in multiple lengths and heights. Among the most commonly used units are the 20ft and 40ft models, available in both standard height and high cube versions. Understanding these container dimensions helps ensure you select a size that efficiently supports your logistics or storage setup.

Common Shipping Container Sizes

Standard Shipping Container Dimensions

Standard containers are typically offered in two primary lengths:

    • •  20-foot container
    • •  40-foot container

A 20ft unit measures roughly 20′ x 8′ x 8.5′, making it suitable for smaller loads and areas with limited space, including sites where only 8 feet of width is available. Meanwhile, a 40ft container provides double the length and significantly more volume, making it a strong choice for large shipments or long-term storage.

When selecting a container, always consider the internal and external dimensions to ensure the space aligns with your operational requirements.

High Cube Container Specifications

High cube containers provide an additional foot of height compared to standard units. This increase in vertical space boosts the container’s total cubic capacity, making it ideal for tall equipment, bulky goods, or high-volume storage. For instance, a high cube version of a 40-foot container offers the same footprint but provides more interior height, giving you greater loading flexibility.

Used Shipping Containers for Sale

For cost-conscious buyers, used shipping containers provide excellent value while maintaining structural reliability. Whether you need a 20ft or 40ft container, pre-owned units can serve a wide range of applications—from storing materials and inventory to supporting seasonal or temporary projects. Always review the container’s condition and dimensions to ensure it meets your intended use.

Storage Container Options

Portable Storage Solutions

Portable storage containers are highly versatile and can be delivered directly to your location. These units work well for homeowners, contractors, and businesses that require short-term or on-site space. With common options such as 20ft and 40ft lengths, you can choose a container that fits your available area and your specific needs, whether for equipment storage, renovations, or inventory overflow.

Container Office Conversions

Shipping containers are also widely used for mobile offices and modular workspaces. Their steel construction makes them durable, secure, and easy to customize. Depending on your space requirements, you can opt for a standard-height container or a high cube model for additional headroom. A 20-foot or 40-foot office container can serve construction sites, remote work areas, or temporary administrative spaces.

Understanding Container Dimensions

Accurate measurements are essential when planning for delivery, installation, or interior layout. Although dimensions may vary slightly depending on the manufacturer, most standard units maintain a width of 8 feet. Reviewing the length, height, and interior space helps you anticipate how much cargo you can store and whether the unit fits your location or logistics workflow.

Choosing the Right Shipping Container

Assessing Your Storage Needs

Before purchasing a container, evaluate the following:

    • •  the type of items or cargo you’ll store
    • •  the duration of use
    • •  available space on your property or job site

This assessment helps determine whether a standard or high cube model, and which length—20ft or 40ft—best matches your application.

Comparing New and Used Containers

Both new and used containers offer benefits depending on your goals:

    • •  New containers: excellent condition, long lifespan, ideal for modifications
    • •  Used containers: budget-friendly, dependable for storage or non-cosmetic uses

Comparing these options ensures you choose the most practical solution.

Evaluating Container Providers

When selecting a provider, look for companies offering multiple container sizes, transparent pricing, and reliable delivery timelines. Customer reviews and service coverage can provide additional insight into their credibility. Working with a reputable supplier ensures you get a container suited to your dimensions, condition, and timeframe.
