How to Choose the Right Size of Shipping Container

By Jed Davies on August 11th, 2025

What Shipping Container Sizes are Available?

At THS Containers, the most popular units are 20ft and 40ft containers. Both are available in standard and high cube formats. For clients with tighter space, smaller options are also available through conversions.

  • 8ft containers – Ultra-compact, ideal for small sites or limited storage.
  • 10ft containers – Great for modest storage or light commercial use.
  • 20ft containers – The global standard, suitable for most shipping and storage needs.
  • 40ft containers – Twice the length of a 20ft, perfect for bulk storage or transporting goods.

According to the World Shipping Council, 20ft and 40ft containers handle over 80% of global trade, but 8ft and 10ft options provide vital flexibility for smaller-scale projects.

What Are the 40ft Container Dimensions?

The 40ft container dimensions make it ideal for bulk storage and transport. Here’s a quick comparison:

Container TypeExternal Dimensions (L x W x H)Internal Capacity
40ft Standard12.19m x 2.44m x 2.59m67.7m³
40ft High Cube12.19m x 2.44m x 2.89m76.3m³

The high cube version gives extra headroom for stacked pallets, tall machinery or oversized equipment.

How Do I Match a Shipping Container’s Size to My Needs?

Your choice of shipping container size depends on three key factors:

  • Volume of goods – 8ft and 10ft are great for light storage. A 20ft fits most homes or small businesses. A 40ft is designed for bulk cargo.
  • Site restrictions – 8ft and 10ft fit into tight yards. A 40ft requires wide access and firm ground.
  • Cost efficiency – A 40ft offers better value per cubic metre compared to smaller units.

For context:

  • An 8ft container suits tools, documents or seasonal storage.
  • A 10ft container works for small office conversions or light commercial use.
  • A 20ft container holds the contents of a three-bedroom house.
  • A 40ft container comfortably doubles that capacity.

Should I Choose Standard or High Cube Shipping Containers?

  • Standard containers are reliable, affordable and widely used.
  • High Cube containers provide an extra 30cm in height for taller cargo.

High Cubes are increasingly popular, with demand rising by 15% year-on-year, particularly in e-commerce and warehousing.

Do Specialist Container Conversions Count as a Size Option?

Yes, specialist container conversions count as a size option. Smaller containers such as 8ft and 10ft units are often created through conversions of larger shells. THS Containers also offers bespoke conversions, from offices and workshops to refrigerated storage.

This flexibility means clients can choose a container that meets both size and function requirements.

What Mistakes Should I Avoid When Choosing a Shipping Container?

  • Paying for too much space – Bigger isn’t always better.
  • Ignoring site clearance – A 40ft won’t fit everywhere.
  • Overlooking door dimensions – Crucial for awkward or bulky goods. Double door containers and side-opening containers offer alternative solutions.
  • Forgetting weight limits – Overloaded containers can be difficult to move.

Careful planning ensures the right choice every time.
