Tips for Choosing the Perfect Unit Size

1. Make an inventory list

Write down everything you plan to store. This helps you determine your real space needs.

2. Think vertically

Most units offer 8–10 feet of height—use it! Shelving helps maximize space.

3. Consider future storage needs

If you may add more items later, size up to avoid moving units.

4. Don’t cram too tightly

Airflow matters to prevent damage, especially for furniture or fabrics.
