How to Choose the Right Storage Unit Size

How to Choose the Right Storage Unit Size

When you’re moving house, downsizing, running a business, or just need a little extra space, choosing the right storage unit size is an important step. Too small, and your belongings won’t fit. Too big, and you might pay for space you don’t need.

At March Self Store, we’re here to make that decision simple. As a local, family-run business in the historic market town of March, we pride ourselves on being friendly, approachable, and flexible. We’ll happily arrange a free viewing so you can step inside units before you commit – that way, you’ll know you’ve chosen the perfect fit.

Below, we’ve put together a clear guide to help you get started.

Pro Tip: How to Organise Your Storage Space

Always stack heavier boxes at the bottom and lighter ones on top. Leaving a small aisle down the middle makes life much easier when you need to retrieve something later.
