Sizing tips

A few things that make storage easier.

Size up if you are unsure

Going one size up costs less than running out of room mid-move. You can always downsize after.

Stack vertically

Heavy boxes on the bottom, lighter on top. Leave a center aisle so you can reach what you need later.

Climate-controlled for sensitive items

Electronics, wood furniture, photos, and documents do better in a climate-controlled unit in Puerto Rico humidity.
