20ft Shipping Containers Felixstowe
A 20ft shipping container provides around 13.9m² (150ft²) of internal floor area in a compact footprint. It can suit stock, tools, equipment, household contents and other general storage where you need more room than a 10ft unit without moving up to a 40ft container.
The useful size is the space inside and through the doors, not simply the 20ft name. Measure large items before ordering and consider how you will reach goods stored at the back. The proposed Felixstowe site also needs enough room for delivery, door opening and day-to-day access.

20ft shipping container dimensions
A published one-trip 20ft standard container drawing gives external dimensions of 6,058mm long, 2,438mm wide and 2,591mm high. Internally, it measures approximately 5,898mm long, 2,352mm wide and 2,391mm high. The end-door opening is approximately 2,340mm wide by 2,280mm high.
| Measurement | Metric | Imperial |
|---|---|---|
| External length | 6,058mm | Approx. 19ft 11in |
| External width | 2,438mm | 8ft |
| External height | 2,591mm | 8ft 6in |
| Internal length | 5,898mm | Approx. 19ft 4in |
| Internal width | 2,352mm | Approx. 7ft 9in |
| Internal height | 2,391mm | Approx. 7ft 10in |
| Door opening width | 2,340mm | Approx. 7ft 8in |
| Door opening height | 2,280mm | Approx. 7ft 6in |
| Floor area | Approx. 13.9m² | Approx. 150ft² |
| Cubic capacity | Approx. 33.2m³ | Approx. 1,173ft³ |
Specifications can vary slightly between manufacturers and individual containers. Another published one-trip specification gives an internal length of 5.84m rather than 5.898m. If machinery, pallets, furniture or shelving will be a close fit, ask for the measurements of the actual unit offered.
Door clearance can be more important than total capacity. An item may fit inside but still be too large to pass through the end doors. Allow working clearance rather than planning around an exact measured fit.
Is a 20ft container the right size?
A 20ft unit works well when you need useful floor area but do not have the requirement or site space for a 40ft container. Think about how the contents will actually be arranged. Stacking can use the height, but goods that need regular access should not be buried behind rarely used items.
If vertical clearance is the problem, a 20ft high cube container provides additional height while keeping the same nominal footprint. If you need substantially more storage length and have the space for delivery and placement, compare a 40ft shipping container.
For heavy or bulky items, consider the loading method as well as dimensions. A standard 20ft container has cargo doors at one end, so everything must be moved through that opening unless a different container configuration is selected.
Buying a 20ft shipping container
Purchase can suit an ongoing requirement where you expect to keep the container. It can also give you more control over future storage arrangements and modifications, subject to the container structure, intended use and any site requirements.
Ask what condition is being offered. One-trip generally means a container has completed a limited initial shipping journey. It does not mean the container has never been handled or transported. Used units can vary in age, repairs, paint condition, dents and surface corrosion.
Wind and watertight describes resistance to ordinary weather ingress through the structure and openings when the container is in suitable condition. Cargo-worthy and CSC status relate to transport considerations and should not be treated as cosmetic grades. IICL refers to industry inspection and repair criteria rather than a guarantee that every container carrying the label is identical.
For storage, inspect or discuss the roof, walls, floor, doors, seals and locking points. Appearance may matter on a visible commercial or residential site, so make that clear rather than assuming all used containers within a broad condition description will look the same.

Hiring a 20ft shipping container
Hire can work for temporary storage, a project with a defined end date or a requirement where keeping the container afterwards would not be useful. Confirm the hire period, permitted use, damage responsibility and collection arrangements before agreeing to the hire.
Collection access matters from the beginning. A container may be straightforward to deliver onto an open site but difficult to remove after new fencing, stored materials, parked plant or building work restricts the route.
Modifications can also be more limited with hired equipment. Discuss shelving, lining, electrics or other changes before carrying out work rather than assuming a hired unit can be altered freely.
Storage, ventilation and security
A standard steel container provides an enclosed space, but the internal environment still needs thought. Temperature changes and moisture can contribute to condensation, particularly where damp goods are stored, or the doors are opened frequently in changing weather.
Ventilation can help manage air movement, while lining, insulation or anti-condensation treatments may be considered for suitable uses. None is a universal fix, so start with what you intend to store and how sensitive it is to moisture or temperature change.
Security also depends on the locking arrangement and site. Some one-trip containers are supplied with a lockbox, which shields the padlock area, but features vary between units. No locking arrangement should be treated as a guarantee against theft. The article on shipping container weather resistance covers related water-ingress considerations.
Prepare the Felixstowe site for HIAB delivery.
The container footprint is only part of the space needed. HIAB delivery uses a vehicle-mounted crane, so the vehicle needs a suitable access route and working position from which the container can be lifted into place.
Before delivery, check:
- the narrowest gate or access point;
- turning and manoeuvring room for the delivery vehicle;
- firm ground on the access route and where the vehicle will stand;
- overhead cables, branches, canopies and other obstructions;
- the distance from the vehicle position to the intended drop point;
- which direction the container doors should face;
- space to open both cargo doors fully; and
- whether access can remain available for future collection or relocation.
Crane reach reduces as the lifting position moves farther from the vehicle, so a container fitting physically into a space does not mean it can automatically be placed there. Photographs, measurements and a clear description of obstacles are useful when access is restricted.
The drop point should provide firm, reasonably level support. If the container settles unevenly, it can twist, often called racking, which may make the doors difficult to operate. Drainage should also be considered so water does not regularly collect around the base. See the guidance on proper shipping container placement before preparing the position.
Planning considerations in Felixstowe
Requirements can depend on the intended use, how long the container will remain, the status and location of the site, neighbouring property, listed status, conservation areas, any change of use and associated works or modifications.
Do not assume that planning permission is always required or always unnecessary. Check the current requirements with the relevant local council for the proposed Felixstowe site before committing to a placement or substantial modification.
Request a 20ft container quote.
Give enough information to assess the container and delivery together. State what will be stored, whether you want to buy or hire, the expected period of use and any particular condition requirements. Mention large items that could be close to the door or internal dimensions.
Include the delivery location, proposed position, gate measurements and any restrictions such as walls, trees, overhead cables or soft ground. You can compare other options through the container equipment range or request a container quote once the storage and access requirements are clear.
