What Size Storage Room Do I Need?

What Size Storage Room Do I Need?

Our grid of storage unit rooms below illustrates typical uses. Please use only as a guide because how you pack and unload, along with the unique nature of the shape of your items, will vary. When you meet us at one of our Madison mini storage facilities, we can open a couple of storage locker sizes so you can physically see the space and visualize your items fitting into that storage room space.

Size Does Matter:
When you are storing boats, cars, campers, etc., size does matter! Before calling a storage facility, you should first know all the dimensions. For boats, know the FULL length on the trailer, width from outside fender to fender and height. The same measurements are needed for campers, trucks, cars, etc.

Larger Doors Needed?

Larger Doors Needed?

At our Dairy Drive location, we do have some 10’x15’, 10’x20’ and 10’x30’ units with 9' wide x 9' tall doors, some 12’x30’ units and a couple 16' wide x 50' deep units.
Ours Are Full-Height Storage Units

Ours Are Full-Height Storage Units

No need to duck ... we have no short ceilings with our mini storage rooms! Many units in the market are in renovated buildings and are shorter in ceiling height. Our drive-up, non-heated units are 8' tall and Dairy Drive climate-controlled units are 10' tall. So overall, we provide more cubic volume than many other storage rooms to rent.
