How to Choose a Top Tier Shelving size or depth

How to Choose the Right Depth of Top Tier Shelving for Your Garage

What Depth Should Your Garage Shelving Be? (Complete Guide)

When homeowners start planning their garage shelving, the first big question is simple: What depth should I choose?

At Top Tier Shelving, we currently offer three sizes: Large (34” deep), Medium (27” deep), and Small (20” deep). Every size is engineered to hold 650 pounds per 4-foot section, so you’re not sacrificing strength—only choosing how much space you want to use.

A new Compact (13” deep) shelf is also on the way for tight spaces. Check back for updates.

Every garage is different—and most already have the perfect solution waiting. If you’d rather skip the guesswork, our Top Tier Designers can create a custom layout for you with 3D drawings.

Start With Your Goals

Before choosing a shelf depth, decide what you want your garage to do:

  • Park vehicles inside (no more scraping frost or unloading in the rain)
  • Create a workshop
  • Build a home gym
  • Support a business or maximize storage

Here’s the tradeoff:

  • Deeper shelves = more storage volume
  • Shallower shelves = more open space and clearance

Before deciding, measure these three things:

  • Vehicle height
  • Ceiling height
  • Clearance needed for movement

Quick guideline:

  • 9'6"+ ceilings: Large shelf works well
  • 8'–9'6" ceilings: Medium is the sweet spot
  • Under 8': Small shelf keeps things comfortable

Large Garage Storage Shelf (34” Deep)

The Large shelf delivers maximum storage volume. It’s built for big totes, coolers, seasonal storage, and anything you want completely out of the way.

The key advantage: large totes fit perpendicular to the wall. That means significantly more usable storage compared to typical shelving systems.

Medium Garage Storage Shelf (27” Deep)

The Medium shelf is the most versatile option. It holds plenty of storage while keeping a lower profile in the garage.

It’s especially useful above garage doors, where space is limited. Even with tight clearance, it still allows totes to be stored efficiently.

If you don’t need maximum capacity but still want serious storage, this is the balance point.

Small Garage Storage Shelf (20” Deep)

The Small shelf is built for lower ceilings and easy-access storage. It’s ideal for areas that aren’t overhead.

One of the best uses is under the garage door rail—a space most garages waste. It becomes perfect for everyday items like fluids, tools, and supplies.

You can also store larger totes parallel to the wall when needed.

Budget Considerations

Here’s the honest truth: deeper shelves use more material, so they cost more.

But every size is built the same way—same strength, same materials, same lifetime warranty. Choosing a smaller depth doesn’t mean settling for less quality.

You’re not buying a wire rack or imported system. You’re getting a smart, American-made shelving system built to last.

Coming Soon: Compact Shelf (13” Deep)

We’ve completed testing on a new 13-inch Compact Shelf, designed for tight areas like above doors, windows, and narrow wall sections.

It’s not available yet—but it’s coming soon.

The Right Depth for Your Garage

  • Large (34"): Maximum storage, tall ceilings
  • Medium (27"): Balanced storage, standard garages
  • Small (20"): Lower ceilings, accessible storage
  • Compact (13"): Tight spaces (coming soon)

Every Top Tier Shelf is made in the USA from aerospace-grade aluminum and built to hold 650 pounds per 4-foot section.
