Tips for packing your storage unit
When it comes to making your belongings fit, how you pack your storage unit is just as important as choosing the right size. The easiest way to save money on storage is to rent a smaller unit—but to fit everything in less space, you have to pack more efficiently.
Follow these tips to maximize your storage space:
- Use sturdy boxes. Choose heavy-duty moving boxes or plastic totes that will stand up to transport and protect your belongings from heat, humidity, and pests.
- Pile it up. Utilize your entire unit by stacking toward the ceiling, but don’t go more than four boxes high to avoid toppling. You can also use heavier furniture as a base for stacking.
- Stack correctly. Place heavier, sturdier items on the bottom and fragile items on top.
- Make an aisle. If you’ll be in and out of your unit, leave space to walk through it and find what you need.
- Organize logically. Place items you want easy access to at the front of your storage unit.
