10x15 Storage Units: What Fits and What They Cost
A 10x15 storage unit is 150 square feet and rents for a national median of $113.40/mo across the 1893 priced 10x15 units we track. It fits a two-bedroom apartment or small house.
What fits in a 10x15?
A 10x15 is 10 feet wide and 15 feet deep, or 150 square feet of floor. In practice that holds:
- The contents of a two-bedroom apartment, both beds included
- A living room, a dining set, and major appliances, with an aisle down the middle
- Long items lying flat, such as a ladder, a kayak, a rolled rug, or trim and lumber
- Small-business inventory with room to walk between the stacks
In boxes: a medium moving box is 18 by 18 inches at the base, or 2.25 square feet, so 150 square feet is room for about 66 of them in a single layer on the floor. Boxes stack, so 4 layers, roughly chest height, is on the order of 264 boxes. Both figures assume you use every square foot and never need to reach the bottom of a stack, so treat them as the ceiling on what a 10x15 holds rather than a packing plan.
What does not fit in a 10x15?
The limits are easier to check than the capacity, because each one comes down to a single measurement:
- A car you also want to walk around. Fifteen feet is roughly the length of a sedan with nothing to spare. There is no room to open a door at the front or squeeze past at the back.
- A three-bedroom house. A third furnished bedroom plus a garage is a 10x20 question.
- Anything wider than 10 feet. The step up from a 10x10 is entirely depth.
What the size name does not tell you
Ceiling height. A 10x15 is 150 square feet of floor and the name says nothing about how high you can go. At an 8-foot ceiling that same footprint encloses roughly 1,200 cubic feet, and more than half of that volume sits above waist height. Ceiling heights vary between buildings and are not part of the advertised size, so ask the facility rather than assuming.
The door opening. The door is not the same as the 10-foot wall behind it. Roll-up and swing doors are sized independently of the unit, so measure your widest single item, such as a sofa, a mattress, or a refrigerator, and confirm the door dimensions with the facility, not just the unit dimensions.
How you reach it. Two 10x15 units at the same price can be very different to move into. A drive-up unit you back a truck up to; an interior unit means a hallway, possibly an elevator, and then 15 feet of carrying at the far end. On moving day that difference is measured in hours.
The mistake people make with a 10x15
The 10x15 is the step most size charts leave out.
Guides tend to jump from "one bedroom" to "three bedrooms," which maps to 10x10 and 10x20 and leaves nothing in between. So when a 10x10 turns out to be slightly too small, it is tempting to jump straight to a 10x20 and pay for 100 extra square feet. The 10x15 adds 50 instead, and it is the smallest size with enough depth to hold a 10x10 load and still keep a walkway to the back wall. Compare all three prices, and how many units we track at each size, before you decide.
When a 10x15 is the right size
- A two-bedroom apartment or a small house
- A family between homes with the whole household in storage
- A renovation that empties more than one room
- Inventory for a small business or an online shop
- A household that needs to get into its unit regularly
What a 10x15 costs
The national median is $113.40/mo, across the 1893 priced 10x15 units we track. That is a midpoint across every city on this site, not a quote: it is the online rate operators publish on their own sites, half the units we track are above it, and none of it accounts for local rates or promotions. Use your own city's page for the number you will actually pay.
10x10 vs 10x15 vs 10x20
Stepping up from a 10x15 to a 10x20 adds 50 square feet, 33% more floor. Both units are 10 feet wide, so every one of those square feet is depth. The unit gets longer, not roomier across.

Common questions about 10x15 storage units
How much does a 10x15 storage unit cost?
The national median online rate for a 10x15 is $113.40/mo, across the 1893 priced 10x15 units we track. Half of those units are cheaper than that and half are more expensive. What you actually pay depends on the city and the individual facility, so compare your own city rather than budgeting from the median.
What is the difference between a 10x10 and a 10x15?
Fifty square feet of depth. Both are 10 feet wide; the 10x15 is 5 feet deeper, which is 50% more floor. The practical difference is the aisle. A 10x15 will take a 10x10 load and still leave a walkway to the back wall.
Is a 10x15 big enough for a two-bedroom house?
For a two-bedroom apartment, comfortably. For a two-bedroom house with a garage or a basement behind it, plan on a 10x20. The extra rooms are usually where the bulky items live.
Can you fit a car in a 10x15 storage unit?
Physically, a short car fits: 15 feet of depth is about the length of a sedan. Practically it is a poor fit, because there is no room left to open a door or get past the vehicle. A 10x20 is the size that leaves working room, where the facility permits vehicle storage at all.
