Find the Perfect Storage Unit Size for Your Needs


Choosing the right storage unit can feel overwhelming—especially if it’s your first time renting. At Goodfellas Storage, we make it easy. Whether you're decluttering your home, storing seasonal items, or preparing for a move, our storage unit size guide helps you quickly estimate the space you’ll need. From small 5x5 units to large 10x30 spaces, this step-by-step guide will walk you through how to match your belongings to the perfect storage unit size.


Using this guide can help you avoid overpaying for space you don’t need—or underestimating what it takes to fit everything in. Follow the four simple steps below to confidently choose a unit that fits just right.

1

Step One: Take Inventory of Your Items

Start by listing everything you plan to store. Include furniture, boxes, appliances, seasonal gear, business inventory, or anything else. Taking inventory gives you a clearer picture of how much space you’ll actually need—and helps avoid surprises later.

2

Step 2: Group Items by Size and Type

Once you have your list, organize your items by category: large furniture (like couches or mattresses), medium-sized items (like dressers or TVs), and smaller belongings (like boxes, bins, or lamps). Grouping your items makes it easier to visualize how they’ll fit together in a storage unit.

3

Step 3: Estimate Quantities and Stackability

Think about how many boxes or items you’re storing—and how well they stack. Can your furniture be turned on its side? Will fragile items need room on top? Estimating both quantity and stackability helps you determine how to use vertical space effectively, which is key for choosing the right unit size.

Step 4: Match Your Needs to a Unit Size

Use your grouped items and quantity estimates to compare against our [Storage Unit Size Guide]. Whether you need a small 5x10 for a few boxes or a 10x20 to store the contents of a 3-bedroom home, our guide makes it easy to match your needs to the right unit—and avoid paying for space you won’t use.
