Finding the Perfect Fit: Storage Unit Sizes Explained
Selecting the right size for your storage needs is crucial when you decide to secure self storage unit dimensions. At IDEAL CONTAINERS in Nairobi, Kenya, we offer a range of standard container sizes designed to accommodate everything from a few boxes to the contents of an entire household or business inventory. Understanding the available secure self storage unit dimensions helps you make an informed choice, ensuring you have enough space without overpaying for unused capacity. Our durable, weather-resistant containers provide a secure environment for your belongings, and knowing the dimensions empowers you to plan your storage effectively. Let us guide you through the options to find the ideal fit for your needs.
Standard Container Sizes Available
IDEAL CONTAINERS primarily offers two standard sizes for our secure storage units, which are based on traditional shipping container dimensions. The most common are the 20-foot and 40-foot containers. A 20-foot container typically offers approximately 1170 cubic feet of storage space. It has external dimensions of about 20 feet long by 8 feet wide and 8.5 feet high. Internally, this translates to roughly 19.3 feet long by 7.7 feet wide by 7.9 feet high. This size is often suitable for storing the contents of a one-bedroom apartment, smaller business inventory, or equipment. Understanding these secure self storage unit dimensions is the first step in choosing wisely.

The Benefits of High Cube Containers
In addition to standard height containers, IDEAL CONTAINERS also offers 'High Cube' (HC) versions. These containers provide an extra foot of vertical space compared to their standard counterparts. A 20-foot High Cube container has external dimensions of 20' L x 8' W x 9.5' H, while a 40-foot HC is 40' L x 8' W x 9.5' H. The increased height internally (around 8.9 feet) is particularly useful for storing taller items, stacking more goods, or accommodating shelving units without sacrificing floor space. For those needing maximum capacity within a given footprint, exploring the secure self storage unit dimensions of our High Cube options is highly recommended.
Calculating Your Storage Space Needs

To choose the right unit, accurately assess what you need to store. Start by listing all items. For household moves, consider the number of rooms and the types of furniture. For businesses, inventory levels, equipment sizes, and document volumes are key factors. Measure any particularly large or unusually shaped items. It's often better to overestimate slightly than to run out of space. Our team at IDEAL CONTAINERS can assist you in estimating the volume and recommending the most suitable container size based on the secure self storage unit dimensions we offer. Visualizing the space can help; imagine stacking boxes or fitting furniture within the internal dimensions provided.
Internal vs. External Dimensions
It's important to distinguish between external and internal dimensions when considering secure self storage unit dimensions. The external measurements define the container's overall footprint and are crucial for delivery and placement considerations. The internal dimensions, however, represent the usable storage space inside. Keep in mind that the internal measurements are slightly smaller due to the thickness of the container walls and structural supports. For instance, a 20-foot container's external width is 8 feet, but the internal width might be closer to 7.7 feet. Always refer to the internal dimensions when planning how your items will fit inside the unit.
Modifications Affecting Dimensions
While the core secure self storage unit dimensions remain standard, certain modifications can slightly impact the internal usability. Adding internal shelving, for example, will reduce the available floor space but significantly improve organization and vertical storage capacity. Insulation or lining added to the walls can also marginally decrease the internal width and height. If you plan on significant modifications like installing workbenches or specialized racking, it's essential to discuss these with IDEAL CONTAINERS. We can advise on how these changes might affect the usable space within the standard dimensions of your chosen container.
