SIZING TIPS
Still deciding?
A few quick checks help you choose with confidence.
Measure your biggest items
Couches, mattresses, and appliances often decide the size more than boxes do.
Plan for an aisle
If you’ll visit often, choose a little more space so you can reach things in the back.
Size up when in doubt
It’s usually easier to have a little extra room than to make a second trip.
