Storage Container Sizes Explained: Which One Do You Need?

Renting a storage container is a bit like ordering concrete: too little and you're stuck mid-project, too much and you paid for air. Getting the size right is the single biggest factor in whether portable storage feels like a bargain or a budget leak.

The good news is that storage container sizes follow a pretty simple logic once you know what fits where. You don't need to measure every couch cushion — you need a rough handle on rooms, not cubic inches.

Here's how our lineup breaks down, from the compact 5x8 up to the full-size 8x20, and how to pick the one that matches your Los Angeles move, remodel, or business overflow.

Storage Container Sizes at a Glance

Our containers run from a compact 5x8 up to 8x16 and 8x20. Every size loads at ground level — no ramps, no lift gates — and every size can either stay in your driveway or ride back to our secure Gardena facility.

The 5x8: One Room, Zero Waste

The 5x8 is the right call when you're storing a single room's worth of stuff. Think a studio apartment, a home office you're converting to a nursery, or the contents of one bedroom during a flooring project.

It typically handles a mattress set, a dresser, a desk or small sofa, and a healthy stack of boxes. Because its footprint is small, it tucks into spots bigger containers can't — a real advantage on narrow Hermosa Beach lots or shared driveways in Culver City.

The 8x16: The Whole-House Workhorse

Step up to the 8x16 when you're dealing with multiple rooms — roughly the contents of a two-to-three-bedroom home. This is the go-to for kitchen remodels where the whole downstairs needs to disappear, or for families staging a house to sell.

Sixteen feet of length means sofas, dining sets, appliances, and mattresses all fit without playing furniture Jenga. Load the heavy pieces first, build stable tiers, and you'll be surprised what disappears into it — our guide on how to pack a storage container walks through the exact loading order.

The 8x20: Full Homes and Serious Projects

The 8x20 is our largest container — built for a full household of furniture or a large commercial project. If you're clearing a three-to-four-bedroom home for a whole-house renovation, or you're a contractor who needs tools, materials, and fixtures secured on a job site, this is the one.

Businesses lean on the 8x20 hardest: seasonal inventory for retailers, staging furniture for property managers, equipment storage between jobs. There's more on that in how businesses can use mobile storage.

How to Choose the Right Size

Skip the tape measure and start with three questions:

• How many rooms are you emptying? One room points to the 5x8. Two or three rooms, look at the 8x16. Four-plus rooms or a whole house, the 8x20.
• What are your biggest pieces? A sectional, a king bed, or a refrigerator needs the length of a larger container even if your total volume is modest.
• Where will the container sit? A tight LA driveway or HOA-regulated street may cap your footprint. Our remote-controlled delivery system places any size with pinpoint accuracy in tight spots, but it's worth flagging space constraints when you call.

A useful rule of thumb for estimating volume: walk each room and count "furniture pieces plus boxes." A typical furnished bedroom is about 15 medium boxes plus its furniture. If you're between sizes after that exercise, declutter first — a weekend of decluttering has downsized many an 8x20 estimate into an 8x16 rental.

If you're comparing container sizes against traditional storage unit sizes (10x10, 10x20, and so on), the math translates closely — our guide on what size storage unit you need covers the self-storage side of the equation.

The Cost Logic: Right-Sizing Saves Real Money

Here's the part that surprises people: the difference between container sizes is usually modest month to month, but it compounds. Rent a size larger than you need for six months and you've quietly paid for empty air the entire time.

Going too small has its own tax — a second container, or a frantic re-sort in the driveway. The sweet spot is a container that's about 85 to 90 percent full: everything fits, nothing shifts in transit, and you're not paying for space you don't use.

Because our rentals are month-to-month with no long-term commitment, you're also not locked into a guess. And if your container is part of a larger interstate move, the FMCSA's Protect Your Move resources are worth a read before you hire any mover.

We don't publish one-size-fits-all pricing because placement, duration, and location all matter — but you can read how storage container costs work to understand the variables before you call.

SoCal Wrinkles Worth Planning For

A few local realities affect sizing more than people expect. Coastal humidity in Redondo or Long Beach means you'll want breathing room around wood furniture and mattresses rather than a crammed-to-the-ceiling load.

Hot inland summers in Riverside County argue for the same: airflow inside the container protects finishes and fabrics. And if your street parking is metered or your HOA limits how long a container can sit curbside, remember you can load up and have us move the container to our secure Gardena facility instead of keeping it on-site.
