What Size Storage Unit Do I Need?
Use the storage calculator above to estimate how much space you may need at I-17 Thunderbird Self Storage. Add furniture, boxes and other belongings, then use the result as a starting point when comparing our available indoor, air-conditioned storage units.
The calculator provides an estimate. The way your belongings are packed, stacked and arranged can affect the amount of space you actually need.
How to Use the Storage Calculator
Make an Item List
Count the items you plan to store. Include boxes and smaller belongings as well as furniture and other large items.
Enter Your Quantities
Find each matching item in the calculator and enter the approximate quantity you expect to store.
Review the Estimate
Consider irregular shapes, fragile pieces, oversized belongings and anything that cannot be safely stacked.
Compare Available Units
Use the estimate to compare current unit sizes and pricing, or call us with the measurements of your largest belongings.
Allow Room for Real Life
A calculator cannot account for every packing arrangement. You may want extra room for an aisle, shelving or belongings you need to reach without unloading the entire unit.
Volume Is Only Part of the Decision
Cubic feet estimate volume, but unit width, depth, height and door clearance determine how your belongings can actually be arranged inside the space.
Think About How You'll Use the Unit
I-17 Thunderbird Self Storage is 100% indoors and air conditioned. Consider how often you expect to visit your unit and leave a practical path to belongings you may need to retrieve regularly.
Measure Your Largest Items
A sectional sofa, oversized desk, large piece of furniture or unusually tall item may affect your unit choice more than its volume suggests. Measure the length, width and height of oversized belongings before renting.
When Should You Ask for Help?
Call us if you are storing an unusually large or awkward item, valuable furniture or a load that cannot be safely stacked. Tell us the dimensions of your largest items and how often you expect to visit your unit.
Our team can help you compare the calculator estimate with currently available units at our Thunderbird Road facility.
