Storage Unit Size Guide

Choosing the right storage unit size can save you money. Here's a quick reference:

Storage Unit Sizes and What Fits

Unit SizeSq FtBest For
5×5 (locker)25 sq ftBoxes, seasonal items, small furniture
5×1050 sq ftStudio apartment, 1-bedroom contents
10×10100 sq ft2-bedroom apartment contents
10×15150 sq ft2–3 bedroom home contents
10×20200 sq ft3–4 bedroom home, small vehicle
10×30300 sq ftLarge home, vehicle + household

When estimating, it's almost always better to rent slightly larger than you think you need. Trying to jam everything into a too-small unit wastes time, damages items, and makes access difficult. A 10×10 unit that's half empty is still more useful than a 5×10 unit packed floor-to-ceiling.

Climate-Controlled vs. Standard Storage

Climate-controlled units maintain temperature (50–80°F) and humidity, protecting electronics, wood furniture, artwork, clothing, instruments, and documents from heat, cold, and moisture damage. They typically cost 25–50% more than standard units. Standard units are fine for non-sensitive items: plastic storage bins, metal tools, patio furniture, and items not affected by temperature swings.

In hot climates (Texas, Arizona, Southeast), climate control is strongly recommended for almost anything — summer temperatures inside a non-climate-controlled unit can exceed 120°F and rapidly deteriorate wood, leather, and electronics.

Pro tip: Always go one size up from what you think you need. It's much easier to fit everything in a slightly larger unit than to squeeze into one that's too small.

Frequently Asked Questions

What size storage unit do I need for a 1-bedroom apartment?

A 1-bedroom apartment typically fits in a 10x10 ft storage unit, which holds one bedroom's furniture, a small living room, and several boxes.

What size storage unit do I need for a 3-bedroom house?

A 3-bedroom house typically needs a 10x20 or 10x25 ft storage unit to hold furniture from all bedrooms plus living and dining room contents.

Should I get climate-controlled storage?

It's worth the extra cost for wood furniture, electronics, photos, and documents, especially in regions with high humidity or temperature swings.

How much extra space should I add for boxes?

Add about 20% extra space beyond your furniture estimate — boxes are often underestimated and end up stacked around larger items.
