Storage Unit Sizes in Martinsville: A Quick Guide

The hard part of renting storage isn't the rental. It's standing in the middle of a room trying to guess how it all packs down. Most people miss by a size, and that means either a cramped unit or money spent on space that sits empty.

At Cardinal State Storage, we help Martinsville folks work this out all the time, so here's the quick version of what each size holds.

The Small Units: 5x5 and 5x10

A 5x5 is about a small closet, good for boxes, totes, and a few small pieces. A 5x10 is more like a walk-in closet and takes a small bedroom's worth of belongings plus a mattress and some boxes. Both are handy for freeing up a room or storing the things you only need now and then.

The Medium Unit: 10x10

A 10x10 is the one most people pick. It's about a bedroom in size and holds the contents of a couple of rooms, furniture and appliances included.

The Big Units: 10x15 and 10x20

A 10x15 holds a small home's worth of furniture and larger items. A 10x20 is close to a one-car garage, enough for a full household.

A Word for Downsizing and Estates

A lot of storage in Martinsville comes during a downsizing or sorting out a family home, and that's usually not a quick job. If you're holding furniture and heirlooms while you decide what stays, a 10x10 or 10x15 gives you room to keep things organized and accessible rather than stacked to the ceiling. The extra space makes the sorting far less stressful.

Still Not Sure?

When you can't decide, walk the units and picture your things inside. We're happy to help you eyeball it so you rent what you need and nothing extra.
