How to Choose a Shipping Container Size

Start with what will go inside

A longer container is useful only if it works for both your belongings and your site. List the largest items first, then note what you need to reach while the unit is in use. Leave room in your plan to open the doors and move items without unloading everything. If you are storing equipment, share its dimensions and how you plan to load it when you ask for a quote.

Compare the listed lengths

Mobile-Stor lists 10-, 20-, and 40-foot shipping containers. Its shipping container page describes standard units as 8 feet wide and 8 feet 6 inches tall. Confirm the usable interior dimensions, door opening and the specific unit's condition with the team before committing; exterior dimensions alone do not tell you whether an item will fit through the door.

• 10 feet: Start here when the storage need is smaller or the proposed space is tight. Check that the items and the delivery plan fit the particular unit.
• 20 feet: A middle option for a mixed storage load. Mobile-Stor identifies this as its most popular rental size; it may be a sensible first size to discuss if your list is neither very small nor very large.
• 40 feet: Consider this when you have a larger volume to store. A longer unit also needs a suitable placement area and a workable delivery approach, so verify both before selecting it.

Match the unit to how you will use it

Decide whether you need short-term storage or a longer-term setup. Mobile-Stor offers containers for rent and purchase, including new and used options. Ask which sizes and conditions are available for your dates and location rather than assuming every listed combination is in stock. If you need shelving, ventilation or another modification, describe it up front; it may affect the unit you choose.

Check the site before settling on a size

Measure the proposed placement area and note nearby structures, gates and overhead obstacles. The space for the container is not necessarily the same as the space needed to deliver it. Our site preparation guide explains what to discuss with the delivery team. For an actual fit and placement plan, send Mobile-Stor your inventory, site details and preferred location.
