Small Storage Units

Popular small storage unit sizes include 5’x5′ and 5’x10′—comparable to a small closet or half bathroom. These units are ideal for seasonal items, small furniture, boxes, or personal belongings. They offer a budget-friendly way to clear out clutter, support short-term projects, or create a bit of extra space.

Great for: College students, apartment residents, or anyone needing extra closet-style storage for items not used daily.

Medium Storage Units

Medium storage units, such as 10’x10′, 10’x15′, and 5’x15′, are ideal for holding the contents of a family room or two full bedrooms—including furniture, appliances, boxes, and bikes. If your storage needs are exceeding your home’s available space, these units offer a practical and flexible solution. They’re typically suited for loads that would fill up to a 16’ moving truck.

Ideal for: People moving, homeowners renovating, or small businesses needing extra space for inventory.

Large Storage Units

Need maximum space? Large storage units—from 10’x15′ to 10’x30′ and beyond—are built to hold the contents of a multi-bedroom home, including large appliances, vehicles, or substantial business inventory. If you’re using one of the largest moving trucks available, these units are designed to handle everything from full furniture sets and multiple mattresses to bulky miscellaneous items.

Perfect for: Families relocating, businesses needing warehouse-style storage, or storing large outdoor furniture and equipment during the off-season.

Vehicle Storage

Vehicle storage parking spaces typically range in size from 10’x20′ for standard cars and motorcycles, up to 10’x30′ or larger for RVs, boats, and trailers. The specific size needed depends on the vehicle’s length and type, with additional space recommended for ease of access and maneuvering. One Storage’s facilities provide secure outdoor parking spaces. Contact the location closest to you to discuss available vehicle storage options and dimensions with the managers. They are available to support you through any questions that arise during the rental and moving processes.
