High Cube vs Standard Container: Height and Cost

A high cube container is 305 mm taller than a standard one: 2.896 m outside instead of 2.591 m. Length and width stay the same. Those extra 30 cm make a big difference for some uses, such as homes, workshops and racking, and none at all for others. This guide compares the two heights, shows what the difference costs in New Zealand and helps you decide whether a high cube is worth it for your project.

Standard and high cube dimensions

Standard containers are often called GP (general purpose) or DV (dry van). High cubes are labelled HC or HQ on listings. Both come in 20ft and 40ft lengths.

For the full set of lengths, widths and floor areas, see our shipping container dimensions page.

What the extra height gets you

The most useful gain is often the door, not the ceiling. A standard container’s door opening is about 2.28 m high; a high cube’s is about 2.58 m. That 30 cm decides whether a tall item goes through the doors at all. Inside, the extra height lets you stack pallets higher, fit taller shelving or a mezzanine, and stand up comfortably once a ceiling lining is installed.

When a high cube is worth it

Sleepouts, offices and container homes

Insulation and linings take height. A habitable container needs insulation in the ceiling and often under the floor as well, and Ruapehu District Council’s guidance on container conversions notes that high density polystyrene insulation products are generally needed to reach the H1 energy efficiency requirements inside a container. The H1/AS1 sixth edition reference building uses R6.6 for roofs, which is a lot of insulation to fit inside a steel box. In a standard container that build-up eats into a 2.39 m ceiling quickly; a high cube keeps usable headroom. That is why designers usually start container homes and sleepouts with high cube units. Our insulation guide covers the options.

Workshops

Overhead lights, a chain hoist, a roller door mechanism or tall machinery all need headroom. A 40ft high cube is the usual choice for a container workshop.

Racking and bulky storage

If you store on pallets, racking or shelving, the extra height adds roughly 12% more volume for the same footprint. For bulky items such as furniture, hay bales or tall equipment, check the door height first.

When a standard container makes more sense

• General storage of boxes, tools and household goods that will not be stacked to the ceiling.
• Buying used. Standard 20ft containers are the most common used unit in New Zealand, which gives you more choice and lower prices.
• Building a shelter roof between two containers, or joining containers. Heights must match, and owners of container builds report that matching heights and brands can be difficult. Buy both units at the same height, ideally from one supplier. See container shelters.
• Low overhead clearance on the delivery route or at the placement spot, such as power lines, trees or carports. A high cube on a truck stands about 30 cm taller.

What a high cube costs in New Zealand

In the Shipping-Containers.co.nz NZ price index, October 2026, a new 20ft high cube had a median asking price of $5,395 incl. GST across 13 listings, about $565 more than the $4,830 median for a new standard 20ft. For 40ft the comparison works the other way round: new 40ft containers on the NZ market are almost all high cubes, at $6,999 to $7,395 incl. GST for mainstream listings, and we found no published price for a new standard-height 40ft.

For a 20ft, the extra cost of a high cube is roughly 12% on the container price, and less once delivery is included. For a conversion that will be insulated and lined, that is a small share of the project. For plain storage, it may buy you height you never use.

Quick decision guide

• Choose high cube for sleepouts, offices, homes, workshops, tall machinery and pallet racking.
• Choose standard for general storage, used purchases on a budget, and anywhere it must match an existing standard container.
• For a new 40ft, expect a high cube unless a supplier confirms standard stock.
