Storage Container Size Guide - The Mobile Attic

Choosing the right container is key to keeping your items safe, organized, and easy to access. Whether you’re storing household belongings during a renovation, putting away seasonal items, or creating extra space for business supplies, selecting the proper size can save you both time and money. Too small, and you’ll struggle to fit everything; too large, and you’re paying for space you don’t need. This storage container size guide will walk you through the most common container sizes available, helping you make a smart and efficient choice for your specific needs.

Choosing the Right Container Size for Your Needs

Selecting the right container size ensures your items are stored safely and efficiently without wasting space or money. Here’s a quick breakdown to help you match your storage needs with the ideal container size.

1. Small Containers (Typically 8ft – 10ft)

Small storage containers are perfect for minimal storage needs, such as decluttering a single room, storing seasonal items, or packing up a studio apartment. They typically hold the contents of one to two rooms and are easy to place in tight spaces. Ideal for students, small renovations, or short-term storage without the need for excessive space.

2. Medium Containers (Typically 12ft – 16ft)

Medium-sized containers are suitable for storing the contents of a 2–3-bedroom home or for handling moderate renovation projects. They offer ample space for furniture, appliances, and boxes while remaining easy to transport and access. These containers are a great choice for families moving between homes, small office relocations, or anyone needing temporary but spacious storage.

3. Large Containers (Typically 20ft – 40ft)

Large storage containers are built to handle major storage needs, such as full-home moves, commercial inventory, or large-scale remodeling projects. With enough space to hold the contents of five or more rooms, they can accommodate heavy furniture, appliances, and bulky items. Ideal for long-term storage, business use, or cross-country moves where maximum capacity is essential.

Factors to Consider When Choosing a Size

Before choosing a container, consider what items you’ll store, how long you’ll need storage, and how often you’ll need access. Weight restrictions, walkways for item retrieval, and room for airflow also matter. Planning ahead helps avoid space issues and ensures your items are protected, accessible, and stored in a container that meets both your budget and needs.

When in Doubt, Go a Size Up

If you’re unsure which size to pick, it’s usually safer to choose the next size up. A slightly larger container gives you more flexibility for organizing, prevents overpacking, and reduces the risk of damaging items. It also provides extra space for last-minute additions and makes accessing your belongings easier during the storage period.
