Self Storage Unit Size Guide

Choosing the ideal storage unit size

Self storage is an increasingly popular service that comes in handy when you need extra room to keep various items away from your home. Whether you are looking to store your camping gear or golf clubs, boxes packed with miscellaneous items, some old furniture or a small boat, self storage can help.

There are several standard unit sizes to consider, including small units (5'x5') and large units (10'x10', 10'x15'). Small units are suitable for a few miscellaneous items and some boxes whereas larger units can hold the contents of a 2-bedroom home. There are also extra-large units such as the 20'x20', similar in size to two-car garages. They can generally fit the contents of multi-bedroom homes as well as different types of vehicles, from cars and trucks to ATVs and smaller RVs and boats.

To help you decide on the type of storage unit you need, we've created a guide to walk you through each unit size. Naturally, it depends on how many things you plan to store, if they are bulky or not, and also on your organizational skills. Keeping your storage unit organized is essential for maximizing space and for easily accessing your items whenever you need them.

Below, check out the most common storage unit sizes and how much can fit inside them!
