What Is the Most Common Storage Container Size?

Our 16-foot storage container is the most common and most popular storage container size for residential moves and on-site storage. It offers the best balance of space, flexibility, and ease of loading for most households.

Why the 16-Foot Storage Container Is the Most Popular

The 16-foot storage container works well for a wide range of projects, which is why it is the most frequently chosen size.

Customers choose this size because it:

Fits the contents of most 3 to 4 bedroom homes
Provides enough room for furniture and boxes without overpacking
Allows some interior access while loading

What Fits in a 16-Foot Storage Container

A 16-foot storage container can typically hold:

Bedroom furniture for multiple rooms
Living room and dining room furniture
Appliances and boxed household items

It is comparable in capacity to a 10′ × 12′ storage unit or a 17-foot rental truck.

What Size Storage Container Do I Need?

The storage container size you need depends on the amount of space you are emptying and the volume of items being stored. Most customers can choose the right size by matching their home or project size to a container category.

Amount of Items Being Stored

Make a quick inventory of large furniture, appliances, and boxes. When in doubt, choosing a slightly larger container helps avoid damage from overpacking.

Types of Items Being Stored

Bulky items take up far more space. Consider how many of the following you have:

Sectional sofas
King or queen mattresses
Refrigerators and washers or dryers
Dining tables and bed frames

How You Want to Use the Container

Loading style matters more than most people realize.

If you want to walk inside the container, choose a larger size
If items will be packed wall-to-wall with minimal access, a smaller size may work
If you plan to access items during storage, extra space is essential

A Guide to Determine What Storage Container Size You Need

Start with the Size of Your Home or Project

A simple way to estimate storage container size is to match it to the space you are emptying.

Studio or small apartment → 8-foot container
1 to 2 bedroom home → 12-foot container
3 to 4 bedroom home → 16-foot container
Larger homes or full household storage → 20-foot container

Consider Large Furniture and Appliances

Large items take up more space than boxes alone. If you have multiple beds, large sofas, appliances, or bulky furniture, choosing the next size up can prevent overcrowding and make loading easier.

Think About How You Will Use the Container

Your loading and access needs affect which size will work best.

If you need to access items during storage, a larger container allows walkways and organization
If you are moving directly from one location to another, a tighter fit may be sufficient

Plan for Flexibility

Projects can change, especially renovations and longer moves. Choosing a slightly larger storage container size provides room to add items, adjust timelines, or reorganize without needing a second container.

Avoid Common Storage Container Size Mistakes

Many people choose the wrong storage container size by underestimating how much space their belongings actually take up.

Common mistakes include:

Forgetting to account for bulky or awkward items
Assuming boxes stack perfectly without wasted space
Choosing the smallest size to save money, then needing a second container

When to Ask for Help

If you are between sizes or unsure, one of our dedicated rental coordinators can help you choose the right storage container size based on your specific situation. Getting the size right from the start saves time, effort, and extra cost.
