How to Choose the Right Storage Unit Size in Roseville

STORE Management | September 10, 2026 @ 12:00 AM

Choosing the wrong storage unit size is one of the most common mistakes first-time renters make. Too small and you're either cramming things in or making a second trip to a second unit. Too large and you're paying for empty space every month.

If you know what you're storing and roughly how much of it there is, choosing the right size is straightforward. This guide walks through the most common unit sizes available at STORE on Baseline in Roseville, what fits in each, and how to think about the decision before you reserve.

Start With What You're Storing

Before you look at sizes, make a rough inventory of what's going into storage. A few questions that help:

  • Are you storing a single room, a full home, or just overflow items?
  • Does it include furniture, or mostly boxes and smaller items?
  • Will you need to access the unit regularly, or store and leave?
  • Do you have large items like a couch, bed frame, dining table, or appliances?

The answers determine your size range before you ever look at a floor plan.

Storage Unit Sizes at STORE on Baseline

STORE on Baseline is a ground-level, drive-up outdoor storage facility in West Roseville near Westpark and Fiddyment Farm. All units feature tall ceilings and drive-up access with no elevators and no interior hallways. Here's how the size ranges break down:

Small Units: 5x5, 5x10, 5x15, 7x10

Best for:

  • A small apartment's worth of boxes and loose items
  • Seasonal decorations, holiday supplies, and outdoor gear
  • College dorm or bedroom overflow between semesters
  • Documents, records, and small appliances
  • Business supplies, promotional materials, and samples

A 5x5 is roughly the size of a large closet. A 5x10 can hold the contents of a small studio apartment or a bedroom. If you're not sure whether small is right, a 5x10 is usually the safer starting point.

Medium Units: 7x15, 10x10, 10x15

Best for:

  • A one or two-bedroom apartment
  • Living room furniture plus boxes
  • Home office contents during a renovation
  • A vehicle's worth of household goods mid-move
  • Business inventory or contractor materials

A 10x10 is the most popular unit size in self storage. It's the equivalent of a one-car garage. If you have a couch, bed, dresser, and a reasonable number of boxes, a 10x10 usually works. Add a dining set or second bedroom and move up to a 10x15.

Large Units: 10x20, 10x25, 12x20

Best for:

  • A two or three-bedroom home
  • Full sets of living room, bedroom, and dining room furniture
  • Garage contents including tools, equipment, and sporting goods
  • Business inventory at higher volume
  • Contractors needing space for equipment and materials

A 10x20 is approximately the size of a one-car garage and handles most two-bedroom home moves. For a larger home or heavier furniture, consider the 10x25 or 12x20.

Extra-Large Units: 10x30, 12x25, 12x30, 12x40 (starting at $165/month)

Best for:

  • Three to four-bedroom homes
  • Full household contents during extended renovation or relocation
  • Commercial inventory at scale
  • Contractors managing large jobsite equipment

The 12x40 is the largest unit at STORE on Baseline, roughly the size of a two-car garage. It's the right choice when you're moving an entire household and need everything in one place.

The Tall Ceilings Advantage

One thing that makes STORE on Baseline worth noting specifically: the tall ceilings across all unit sizes. Standard storage units often have 8-foot ceilings. STORE on Baseline's units are notably taller, which means you can stack boxes and shelving higher and get more usable cubic footage out of whatever size you rent.

If you're bringing shelving units, you can maximize vertical space significantly, especially in medium and large units. This is worth factoring in when deciding between sizes. A 10x10 with 12-foot ceilings holds meaningfully more than a 10x10 with 8-foot ceilings.

Tips for Maximizing Whatever Size You Choose

  • Disassemble furniture where possible. Bed frames, tables, and shelving take up significantly less floor space when broken down.
  • Use the full height of the unit. Boxes and shelving can go high given the tall ceilings.
  • Store items you'll need to access at the front, rarely-needed items at the back.
  • Leave a center walkway if you need regular access to items throughout the unit.
  • Label boxes on the side, not the top. When stacked, side labels stay visible.
  • Fill boxes completely to avoid crushing. Partially filled boxes collapse under weight.
