What Should Portland Residents Consider When Choosing a Storage Unit Size?
In addition to dimensions, Portland residents should consider what they’re storing, how long they plan to store it, and how often they’ll need access.
Start by measuring large belongings such as sofas, mattresses, dining tables, appliances, and other furniture. Then estimate how many boxes or storage bins you’ll need to fit around them.
