A caller asks, “What size unit do I need?” They want a useful answer, but a phone conversation cannot show exactly how their belongings will occupy a particular space. The team member’s job is to narrow the choice, explain what remains uncertain, and help the caller check a real unit before relying on an estimate.
A good answer begins with the belongings, not a memorized list of unit sizes. It also leaves room for how the caller plans to use the space. Someone who needs to reach a box regularly may arrange the same inventory differently from someone who plans to store everything until a move.
Start with a workable inventory
Ask the caller to describe what is going into storage. A short list is more useful than a broad label such as “one bedroom.” Invite them to name large pieces, the approximate number of boxes, and anything awkward to carry or arrange. Ask whether they will need a path to reach items after move-in.
A few questions can make the conversation concrete:
- Which pieces take up the most room?
- Are any items unusually long, tall, or difficult to move?
- About how many boxes or smaller containers are there?
- Will you need a path to reach particular items after move-in?
- Is this the complete list, or are you still packing?
The answers may change as the caller prepares to move. Say so plainly. If the inventory is incomplete, treat any size discussed on the call as a starting point for comparison.
Ask how the caller needs to use the space
Fit involves more than placing every item behind a door. Ask whether the caller expects to retrieve items during the rental and which ones should remain easy to reach. Ask about move timing, too: it helps establish when a specific unit needs to be checked and whether the caller has time to inspect it.
Keep these questions tied to the caller’s decision. You do not need to design a packing plan over the phone. You need enough detail to tell whether the caller is imagining a tightly packed space or one with room to move among their things.
For example, hypothetical call language might be: “Based on the pieces you’ve listed, I can help compare the sizes we offer. If you’ll need to get to those boxes often, let’s account for a path rather than assuming the whole floor will be packed.” That gives the caller a reason for the questions without claiming a particular arrangement will work.
Make the size comparison provisional
Published size examples can help a caller picture the options, but they are estimates. Public Storage’s size guide says unit sizes are approximate and can vary by facility. A size label alone cannot establish the usable dimensions, doorway clearance, or access details of the specific unit the caller might rent.
After hearing the inventory, describe the likely options as candidates: “This sounds like a size worth checking,” or “We should compare these two available sizes against your list.” Avoid turning a sample fit illustration into a guarantee. If one bulky item is the deciding factor, identify it. The caller then knows what to measure or bring up during a site check.
If the caller asks for certainty, be direct about the limit: “I can narrow the options from what you’ve described, but I’d want to verify the actual unit dimensions and access before telling you it will fit.” A clear limit is more useful than a confident guess that the team cannot substantiate.
Close with a specific check
Summarize the inventory points that drove the recommendation, including any item or access need still in question. Then offer the next step your facility can actually support: checking the dimensions of a particular unit, arranging a visit, or reviewing another size with the caller. Verify the unit’s current details through the facility’s own process before stating them as facts.
Keep the size discussion separate from a promise about availability. The next guide in this series, how to explain climate-controlled storage, addresses a different question that may come up while comparing units.

Before ending this call, give the caller one practical action: write down the few large items and access needs that matter most, then use that list to check the dimensions and doorway of a specific unit.
