May 28, 2025
A Simple Guide from Affordable Family Storage
Not sure how much space you need? You're not alone. That's why we created a handy Storage Size Guide
to give you a clear, visual overview of your options. It’s a great place to start if you want to get a feel for what each unit can hold before you make a decision. Once you’ve browsed the guide, come back here for a more detailed breakdown of each size and how it fits real-life storage situations.
Choosing the right storage unit can feel a little overwhelming—especially if it’s your first time renting. You don’t want to pay for more space than you need, but you also don’t want to find yourself in a tight squeeze halfway through your move. That’s why we put together this size guide: to help you figure out exactly what unit fits your needs, your lifestyle, and your belonging
Whether you’re moving, remodeling, downsizing, or just doing some seasonal decluttering, here’s what to expect with each unit size:
5x5 Storage Unit – Small But Mighty
A 5x5 unit is about the size of a large closet. It’s perfect if you’re looking to tuck away a few things but don’t need a full room’s worth of space. Great for people who want to declutter without overcommitting.
You can typically store:
- Seasonal items like holiday decorations
- A few small furniture pieces
- Boxes of clothing, books, or keepsakes
5x10 Storage Unit – Ideal for Tight Transitions
This unit gives you a bit more breathing room than a 5x5. Picture a walk-in closet or a small office space. It’s ideal for people in temporary transitions, like students storing items between semesters or those moving between apartments.
You can typically store:
- A twin bed, dresser, and nightstand
- Several medium to large boxes
- Bikes, totes, and seasonal gear
10x10 Storage Unit – Most Popular Choice
If you’re not sure what size you need, this is often a safe bet. The 10x10 is one of the most versatile options, offering enough space to store the contents of a typical one-bedroom apartment. It’s a great middle ground for short or long-term storage.
You can typically store:
- A queen-size bed, dresser, and nightstands
- A couch, dining table, and chairs
- Kitchen appliances and multiple boxes
10x15 Storage Unit – More Room for Furniture
Need more space but don’t want to jump to a full garage-sized unit? The 10x15 gives you flexibility for larger items and is great for people going through renovations, relocations, or home transitions.
You can typically store:
- Contents of a two-bedroom apartment
- Larger appliances like refrigerators or washers/dryers
- Office furniture or small business inventory
10x20 Storage Unit – The “Full House” Option
This size is equivalent to a standard one-car garage. It’s a great choice if you're packing up an entire household, including furniture, boxes, and large equipment. People often use this size during major moves or to store vehicles and trailers.
You can typically store:
- Contents of a 2–3 bedroom home
- Larger items like sofas, wardrobes, and patio furniture
- Motorcycles, ATVs, or lawn equipment
10x30 Storage Unit – Extra-Large Storage
If you’ve got a big job, this is the size for you. A 10x30 unit can hold a lot—whether you're storing the contents of a large home, multiple vehicles, or business equipment. Ideal for long-term use or when you want plenty of space to stay organized.
You can typically store:
- Contents of a 3–4 bedroom house
- Business inventory or large commercial items
- Boats, trailers, or multiple motorcycles
