How to Measure for Self Storage

Choosing the right big self storage unit comes down to knowing what you're working with. A little measuring upfront saves you from renting too small — or paying for more space than you need. Here's how to approach it:

Start with your largest items first.

  • The biggest pieces in your haul — typically large furniture, appliances, or vehicles — will determine your minimum unit size. Measure each item's length, width, and height, and factor in that items will often be stacked or stored on their sides to maximize space.

Add a buffer.

  • Once you've totaled up your square footage, build in some extra room. A unit that's packed wall-to-wall is difficult to navigate and makes retrieving items a hassle. A general rule of thumb: aim for about 20–30% more space than your measurements suggest you need.

Account for vertical space.

  • Large self storage units typically offer 8–10 feet of ceiling height. Stacking boxes and using shelving units can effectively double your usable storage area — so don't just think in square feet, think in cubic feet too.

Real-Life Measuring Examples

Dining Room Set

Dining tables vary quite a bit in size, but most standard rectangular tables land somewhere between 36–42" wide and 60–84" long. That puts the table alone at roughly 15–25 square feet of floor space — and that's before you factor in chairs. Six chairs at an average of 18" x 20" each add another 15 square feet or so, depending on how they're arranged. Stacking or nesting chairs reduces that footprint considerably, so it's worth doing that where you can. If your table has extension leaves, measure it fully extended — that's the dimension that matters when you're figuring out whether it'll fit through the unit door.

Kids' Bedroom Furniture

A typical children's bedroom setup — a twin or full bed frame, dresser, nightstand, and small bookcase — will take up somewhere in the range of 28–40 square feet of floor space, though that number shifts depending on the size and style of each piece. Bunk beds in particular are worth measuring assembled before you take them apart, since the frame footprint is what you're really working around. And it's easy to underestimate the extras: mattresses, storage bins, a small desk, a toy chest. Do a full room inventory before you settle on a unit size — kids' rooms tend to have more in them than they appear to.

Great service

Worked with Jackie on 8/6/25. Great and knowledgeable service. I was able to rent a 30x12 spot for my RV and a 10x20 for my trailer. Excellent price, no complaints. Thank you.

Best customer service for storage units!

Self storage was very helpful! They made sure to get me the best deal in the area. 10x20 climate controlled unit for 185$ online! The nice man I spoke with ( forgot his name) went above and beyond! I was really impressed with how much care and consideration he put forth to assist me. Other storage places wanted 220$ plus to get the same 10x20 I was needing. Thanks self storage! I'll be telling everyone I know of my great encounter with the nice guy that took my call.!

Reserving my unit 10x20…

Reserving my unit 10x20 was such a pleasant experience. It was so easy. I just scrolled through the web page until I found the unit I needed and filled out the easy and short form, and hit the ok. It was done, and no credit or debit card needed to reserve. Amazing!! Then I got a confirmation email with complete instructions. wait, then i got a call from them, making sure everything went well with my order. They are absolutely GREAT. I recommend them.

Affordable rates, friendly service, clean units!

I'm really impressed with the quality of the storage! The manager is friendly and funny and resolved all of my concerns and answered all of my questions. We even got a free lock for setting up a reservation online! This is also by far the best price I have found for a 10x30 storage unit in the area, better by $40 / month than the competition!
