40ft Side Opening Shipping Container Dimensions

A 40ft side opening shipping container gives full or near-full access along one long side, with standard cargo doors at one end. Many 40ft side openers are supplied as high cube units, which means they are taller than a standard-height container. That extra height can help with bulky stock, machinery, racking and conversion work.

The exact dimensions vary by manufacturer and door system. Some 40ft high cube full side access containers have a long opening with no central post. Others use different door sections or folding arrangements. Because the side doors and frame carry different loads from a standard container, the internal height can vary more than buyers expect.

The table below gives useful planning figures for common 40ft high cube side opening containers. Treat these as a guide, not a substitute for the current unit drawing.

High cube height and internal clearance

High cube containers are taller than standard containers, but a 40ft side opener should not be judged by external height alone. The internal clearance depends on the roof, floor, side-door frame and threshold. Published specifications for high cube side opening units can show different internal heights, so confirm the exact figure if your load is tall.

This is especially important for machinery, storage cages, stacked pallets, exhibition kit, shopfitting materials and racking. Lining and insulation will reduce internal dimensions further. Electrics, lighting, ventilation, heating and cooling equipment can also take up space, depending on how they are fitted.

If you are comparing with a standard end-opening unit, start with the 40ft standard container dimensions, then allow for the side opening frame and the high cube height where applicable.

Side door clearance and loading access

The main value of a 40ft side opening container is the long side access. A clear opening of more than 11.5m can let you load or pick goods along nearly the full length of the container. This can save time when handling pallets, long materials, event equipment, plant parts or stock that changes frequently.

Door clearance is not only the width shown on a drawing. You also need to think about the height of the opening, the swing or fold of the doors, the ground outside the opening and the working route for a forklift or pallet movement. Large steel side doors need room to open and room to be secured safely while people are working.

Check which long side opens before delivery. Rotating a 40ft container after placement may not be practical on a tight site. If the doors face the wrong way, the container can lose the main advantage you bought or hired it for.

Weight, payload and floor area

40ft side opening containers are heavier than many standard units because of the side doors and reinforcement. Typical tare weights in supplied specifications sit above six tonnes, but the actual tare weight, max gross weight and payload must be read from the container plate or current specification.

Some published drawings list a floor area of around 27.5m² and a cubic capacity of around 68m³ for a 40ft open side unit. Those figures are useful for storage planning, but usable space depends on how goods are loaded, whether racking is fitted and how much clearance is needed for handling.

For static storage, check the floor condition, point loads and how weight will be spread. For cargo movement or export, check CSC status, tare, payload, gross rating, lashing points and carrier acceptance. A CSC plate is important, but it does not remove the need to confirm suitability with the shipping line or freight forwarder.

Planning the site footprint

A 40ft side opener takes up a large footprint before the doors are opened. Plan for the container length, the door working area, the delivery vehicle, crane reach where used and safe access around the unit. The long side must not be blocked by fencing, scaffolding, stored materials, parked vehicles or neighbouring property.

Level ground matters. A long container placed on uneven ground can twist, and that can make side doors harder to use. Concrete, compacted hardcore or suitable level supports are better than grass or soft ground. The base should also allow drainage so water does not sit under the floor or around the lower rails.

Check overhead clearance as well. High cube units are taller, and delivery may involve lifting the container from a lorry. Look for overhead cables, branches, gutters, canopies, signs and roof edges. The container delivery guide will help you gather the access details before arranging a delivery.

Choosing 40ft side opening, standard or another size

A 40ft side opening unit suits customers who need length and access. It can be a strong choice for organised pallet storage, long materials, event stock, machinery, workshop support and some conversion projects. It is less suitable where the site is narrow, where the long side cannot be kept clear, or where the goods can be handled easily through end doors.

A standard 40ft container may be simpler and easier to place if you do not need side access. A 20ft side opening unit may be easier on restricted sites if you need wide access but not the full 40ft length. Compare the main buying and hire routes through shipping containers for sale and container hire.

If the container will be modified, confirm the final internal dimensions after lining, insulation, vents, electrics, racking or doors are added. Planning requirements can depend on intended use, duration, site status, neighbouring property, listed status, conservation areas, change of use, works and local policy. Check current requirements with the local council before committing to long-term placement or conversion.

What to send with an enquiry

Good measurements lead to better advice. Send the delivery postcode, intended use, preferred hire or purchase route, load type, largest item dimensions, expected loading method and any export requirement. Also include site measurements, ground type, door orientation and overhead restrictions.

Photos can help where access is tight, but measurements are still needed. Mark the proposed position and show which side should open. If a HIAB delivery is being considered, the lorry needs safe standing space as well as crane reach. Collection access should also be considered if the unit is hired or may be moved later.
