Unit Sizing 101: Helping Your Customers Pick the Right Box (And Saving Your Sanity)

“Will all my stuff fit in a 20-footer?”

If you had a dollar for every time a customer asked that, you wouldn’t need to rent containers. Sizing confusion is one of the biggest bottlenecks in the sales process. If the customer under-estimates, they’re frustrated. If they over-estimate, they feel ripped off.


The Cheat Sheet: Portable Storage Sizing

Helping your customers visualize space is the fastest way to close a sale. Here is how to break it down for them:

Unit SizeEquivalent SpaceBest For…
8’ - 10’ UnitA large walk-in closetDorm rooms, studio apartments, or clearing out a garage.
16’ Unit3-4 rooms of furnitureSmall 2-bedroom homes or large apartment moves.
20’ UnitA standard one-car garage3-4 bedroom homes or heavy construction equipment.

Why Getting Sizing Right Matters for YOUR Bottom Line

When a customer orders the wrong size, it isn’t just their problem—it’s yours.

  • The “Dry Run” Cost: Your driver shows up with a 10’ unit, the customer realizes it’s too small, and you have to drive back to the yard empty-handed.
  • The “Tetris” Delay: A customer trying to cram too much into a small unit will take longer to load, delaying your driver’s pickup schedule.

The Fix: Visual Sizing Tools

The best way to solve this is to stop telling and start showing.

  1. Interactive Calculators: Embed a sizing calculator on your booking page that adds up their large items (couch + bed + fridge).
  2. The “Virtual Tour”: Post a 30-second video of each unit size on your website so customers can see the scale.
  3. CRM Integration: Use a CRM that allows you to attach “Sizing Guides” to your initial quotes automatically.

Summary: By educating your customer on the front end, you ensure a smoother delivery day and a happier client on the back end.
