Not sure how much space you need? You're not alone — it's one of the most common questions we get. This guide walks through every unit size we offer at Harbor View Self Storage, what you can realistically fit inside, and how to choose the right one without paying for space you don't need. All of our units are indoors and fully climate-controlled — that matters in Vermont, where cold winters and humid summers can damage furniture, electronics, documents, and anything sensitive to temperature swings. Whether you're storing a few boxes or the contents of a full house, every unit here is protected from the Champlain Valley's extremes year-round.

Small Storage Units
Best for: Personal items, seasonal gear, small apartment overflow
Think of a 5×5 as a large walk-in closet. It's a great fit when you don't need to store furniture — just boxes, bins, and smaller items. Vermont-specific uses: ski equipment and poles, snowshoes and hiking gear, off-season clothing, holiday decorations, and small sports equipment.
What fits:
What doesn't fit: a sofa, dining table, or any full bedroom set.
Best for: Studio apartment, dorm room cleanout, one room of furniture
A 5×10 is roughly the size of a standard walk-in closet or a pickup truck bed. It's the most popular size for people between leases or decluttering a single room.
What fits:
What doesn't fit: a full dining room set plus a bedroom — that starts to push into the next size up.
Best for: One-bedroom apartment, large closet cleanout, small business inventory
A 5×15 is a long, narrow unit — great for items that stack well (boxes, bins) or long items like skis, lumber, or kayaks. It holds a full one-bedroom apartment's worth of furniture without appliances.
What fits:
Medium Storage Units
Best for: One-bedroom apartment with appliances, small home office contents, business records
The 10×10 is the industry standard "medium" unit — it's what most people picture when they think of self-storage. It's roughly the footprint of a standard bedroom, and it can be packed efficiently to hold a surprising amount.
What fits:
Vermont-specific use: Snowbirds storing the full contents of a Vermont seasonal property while away.
Best for: Two-bedroom apartment or small house, vehicle storage (call to confirm availability), business equipment
A 10×15 is the size of a large bedroom or a 20-foot moving truck. It's the right call when you're storing the contents of a 2-bedroom home, or when you have oversized items like a small boat, canoe, or contractor equipment.
What fits:
Large Storage Units
Best for: Two-bedroom house full contents, contractor equipment, large vehicle or boat
A 10×20 is the size of a one-car garage. It's right for people doing a full home move or long-term storage of a house's contents during a renovation or relocation.
What fits:
Best for: Three-bedroom house, large vehicle, business warehouse overflow
What fits:
Best for: Four or five-bedroom home, large-scale business storage, multi-vehicle or equipment storage
Our largest unit — equivalent to an extra-long one-car garage. Right for large estate cleanouts, full-business relocations, or storing the complete contents of a large Vermont home.
What fits:
At Harbor View, every unit — small or large — is temperature and humidity controlled. That's not standard everywhere, and it matters more in Vermont than most places. Here's why it's worth it regardless of what you're storing:
Vermont winters regularly drop below 0°F. Wood furniture cracks, electronics fail, and certain plastics become brittle in uncontrolled cold storage. Vermont summers bring humidity spikes from the lake that can warp wood, promote mold, and damage paper documents, photos, and textiles.
Our HVAC-maintained facility holds a consistent temperature and humidity level year-round. Whether you're storing ski gear in July or patio furniture in January, your belongings are protected.
Regardless of which size you choose, these habits make a big difference:
