What Size Storage Unit Do I Need? A Room-by-Room Sizing Guide

Choosing the right storage unit is one of the most important decisions you’ll make when storing your belongings. Pick a unit that’s too small and you’ll struggle to fit everything in. If you choose a unit that’s too large, you might find yourself paying for space you don’t need.

If you’re comparing storage unit sizes, the simplest approach is to estimate your requirements room by room. Understanding the volume of furniture, appliances, boxes, and household items you plan to store will help you select the right unit from the start.

List:

You may not need to store everything.

Many customers store the following:

Failing to Measure Large Furniture

Always measure:

• Beds
• Wardrobes
• Appliances

before selecting a storage unit.

Ignoring Future Storage Needs
