What Size Storage Container Do I Need?

Choosing the right portable container size isn’t just about square footage. A few key details about your move or storage project will help you determine which option makes the most sense:

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

Tips for Choosing the Right Portable Container Size

Choosing between portable storage container sizes is easier when you plan ahead. These practical tips can help you avoid common mistakes and make sure your container fits your move or storage needs.

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 Container Size Mistakes

Many people underestimate how much space their belongings take up.

Common mistakes include:

  • Forgetting to account for bulky or awkward items

  • Assuming boxes stack perfectly with no wasted space

  • Choosing the smallest container size to save money, then realizing it’s not enough

Consider Delivery Space and Property Access

Before choosing your portable container size, think about where the container will be placed. Make sure there is enough space on your driveway or property for the size you select. Larger containers may require more clearance for delivery and pickup.

Know When to Ask for Help

If you’re unsure between two moving container sizes, it’s better to ask. Our rental coordinators can help you compare options and choose the portable container size that best fits your specific project.
