Choosing the proper storage unit size sets the tone for a smooth move and an efficient setup. Start with your must-store list, then match it to real dimensions so you do not overpay or run short on space. At Thunder Storage & Garage, we rent clean, secure garages for storage and customer projects, but we do not offer maintenance or repair. Our goal is to help you pick a space that fits your items and your plans.

Know What You’re Storing

Create quick categories. Boxes and totes stack well. Furniture needs a floor area and a protected room. Vehicles, ATVs, and small boats require driveway-style clearance plus turning space. Hobby benches or seasonal gear benefit from wall space and clear walkways. A fast inventory helps translate belongings into square footage.

Measure And Stack Smart

Tape out your largest items before you choose. Sofas, mattresses, and appliances set your minimum footprint. Count boxes and plan to stack them three to four high with safe load limits. Use shelving when possible to keep aisles open. A 10×10 fits an apartment set with room to navigate. A 10×20 often handles a small home, plus bikes and yard tools. If you need to stage a project table, size it up so you can move around without shifting stacks.

Think Access And Duration

Short-term storage can pack tighter. Long-term storage benefits from a center aisle so you can reach the back. If you will visit often, leave a loading zone at the front and keep heavy items at waist height. Add room for a ladder and a dolly if you will be rotating gear. Plan for growth. A little extra space costs less than renting a second unit later.

Consider Climate And Power

Certain items prefer stable temperatures, like electronics, photos, instruments, and finishes. Ask about climate-controlled options if your goods are sensitive. If you plan light project work, confirm power availability and rules for on-site use. We can walk you through unit types and policies so your setup stays code-compliant and safe.
