How to Choose the Right Size Storage Unit for Your Needs

Whether you’re downsizing, decluttering, or moving, one of the most important storage decisions you’ll make is size. Go too small, and you’re stuck playing Tetris with your boxes. Go too big, and you might end up paying for space you don’t use.

So how do you choose the right size storage unit? We’ve got you covered with this simple breakdown to help you find the perfect fit.


Why Size Matters

📦 Too small = frustrating & overcrowded
📦 Too big = wasted money on unused space

Getting the right size ensures you can store efficiently and access your items when you need them—without unnecessary cost or hassle.
