    Seasonal Storage

    • 10x10: If you're looking to store a motorcycle, ATV, or lawn mower during the off-season, a 10x10 storage unit can accommodate your needs.

    • 10x15: Upgrade to a 10x15 unit if you want to store a lawnmower alongside a motorcycle or ATV. For long-term storage where you need to regularly access items, the 10x15’s extra depth provides a walking aisle that a 10x10 may not allow once fully packed.

    Home Renovations or Remodels

    • 10x10: Choose a 10x10 for home renovations that require you to store bedroom sets, home appliances, living room furniture, and more.

    • 10x15: Upgrade to a 10x15 if you need long-term storage for large items like a couch, dining set, or bedroom suite during a major remodel or renovation project—the extra depth makes items easier to organize and access.

    How to Choose the Right Storage Unit Size

    Tips for Choosing:

    • List Everything First: Write down every item you plan to store so nothing gets overlooked.

    • Measure Your Items: Record the measurements of your belongings, including boxes, appliances, and furniture.

    • Test Layout Ideas: Mark out possible unit arrangements using painter's tape on your floor to visualize how everything could fit.

    • Utilize Vertical Storage: Most units are around 8 feet tall, so remember to take advantage of vertical space by stacking items whenever possible.

    • Maintain Clear Pathways: Design your layout with clear walkways so you can easily reach your items later.

    • Size Up if Unsure: If you’re not confident everything will fit, choosing a slightly larger unit now can prevent headaches on move-in day.

    Additional Considerations:

    • Accessibility: The more frequently you need access to your stored items, the more room you'll want for larger paths through the unit.

    • Climate Control: If you need to store temperature-sensitive items, you might want to consider renting heated, air-cooled, or climate-controlled storage.

    • Drive-Up Access: If you're storing any large, heavy, or bulky belongings, a drive-up storage unit can make moving them in and out less of a hassle.

    • Ceiling Height: Select locations offer storage units with 10-foot ceilings, which is an ideal option for oversized items.

    • Vehicle Storage: If you're storing a motorcycle, snowmobile, jet ski, or ATV but still want room to store other items, you may want to opt for the larger unit.

    Is a 10x10 or 10x15 unit better for a two-bedroom apartment?

    Either a 10x10 or 10x15 storage unit can be used to store the contents of a two-bedroom apartment. However, if you have a lot of furniture or want to store large home appliances, a 10x15 storage unit will provide more room.

    Both 10x10 and 10x15 storage units are great options for storing motorcycles, ATVs, jet skis, and similar-sized vehicles. However, if you plan on storing more than one vehicle or will be storing other items alongside your vehicle, we recommend renting a 10x15 unit to give you more space.
