How Tall Are Storage Units?

The storage units at Extra Space Storage are typically 8 feet tall. We do have shorter and taller ceilings in self storage units at select facilities. Certain storage units have 10-foot ceilings (and taller) to accommodate unique storage needs like storing larger vehicles. In large cities like New York City, we also offer reduced-height storage units that offer the same square footage with less cost.

Storage Units for Oversized Belongings

We get questions all the time about what size storage unit is necessary for specific items like queen and king-size mattresses, pianos, motorcycles, cars, and more. Let’s take a look at some of these items and which self storage sizes work best for them.

Filled Storage Unit

Mattresses

This obviously depends on which mattress size you’re storing. Smaller mattresses will fit in almost any storage unit, while queen and king-sized mattresses won’t fit in smaller units.

  • Twin and full-size mattress: A 5×5 will easily accommodate all mattresses smaller than a queen-size mattress.
  • Queen-size mattress: Though you might be able to squeeze a queen-size mattress into a 5×5, it’s going to be a really tight fit. A 5×10 will be much better.
  • King-size mattress: There’s no chance you’ll get a king-size mattress into a 5×5, but like the queen-size mattress, the king will fit nicely in a 5×10 or larger.

Motorcycles

Almost all motorcycles are longer than five feet in length. This makes 5×10 storage units (and larger) a good fit for anyone looking for an indoor vehicle storage option for their bike.

Automobiles

The smallest cars on the market might be able to fit into a 10×15 storage unit, but the vast majority of automobiles, including cars, SUVs, vans, and even some pickups, will fit into a 10×20 pretty easily. Some larger vans and trucks will require a 10×25 or a 10×30.

Pianos

Pianos come in all shapes and size, but we’ll take a look at a couple popular options to give you an idea of what to look for.

  • Vertical Pianos: These include keyboard, spinet, console, studio, and upright pianos. These pianos are often right around 5 feet wide, so you’ll want at least a 5×10 storage unit.
  • Grand Pianos: Grand pianos vary greatly in size, but they’re generally around 5 feet wide and 5 to 8 feet in length. This makes a 10×10 the best bet for storing a grand piano.

Tips for Organizing Your Storage Unit

  • Use sturdy moving boxes or heavy-duty plastic containers of uniform size.
  • Group boxes by fragility or weight with heavier boxes on the bottom and fragile items on top.
  • Stack boxes no more than four high. You can also place boxes on top of sturdy furniture.
  • Place items you know you’ll need to access toward the front of your storage unit.
