10x20 Storage Unit: What Fits? What Doesn't?

If you're looking for a spacious storage solution that can hold just about anything, a 10x20 storage unit should be a consideration! This unit is one of the most versatile options available. It will provide you with enough space to comfortably store the contents of a multi-bedroom home, business, or vehicle. 

In the guide, we'll break down what fits, what doesn't, and how to make the most of your 10x20 storage space. Plus, we'll give you some highlights on pricing and vehicle storage.

How big is a 10x20 storage unit?

A 10x20 storage unit will provide approximately 200 feet of floor space. Since most self-storage units are about 8 feet high, you'll have around 1,600 cubic feet of space.

Difficult to visualize? Think of it as the size of a standard one-car garage. This storage unit size can fit the contents of a 3-4 bedroom house, and is also ideal for most vehicle storage needs.

What items fit in a 10x20 storage unit?

A 10x20 storage unit can hold quite a lot. Due to its spaciousness, it can fulfill both household and business storage needs. Some items that typically fit in a 10x20 include:

• 3-5 piece living room sets, comprised of a couch, chairs, and coffee table
• Dining table with 4-6 chairs
• Multiple mattresses, ranging from twin to king
• Full bedroom sets 
• Multiple kitchen appliances, including a fridge, washer/dryer set, and dishwasher
• 30-50 medium-to-large-sized moving boxes
• Sports and recreational gear, such as bikes
• Patio furniture
• Lawn equipment and power tools
• Most vehicles, including cars, small trucks, and motorcycles. You can even fit your jet ski or ATV.

What will not fit in 10x20 storage?

10x20s are spacious, but they don't come without limits. Some items that won't fit?

• Oversized Vehicles: Think RVs, boats 20+ feet in length, and trailers over 20 feet
• Lifted trucks
• Extra-large construction equipment
• Large building materials, including long beams and full drywall sheets

While grand pianos may fit dimensionally, this instrument requires meticulous storage. We recommend sizing up and also choosing climate control.

If you're unsure whether your belongings will fit, you can simply check an online size guide. For even better visualization, you can see the unit in real life. At Storage Star, we strive to provide top-notch customer service and are delighted to offer you a tour before you commit to renting a specific unit size.

Can I use a 10x20 for vehicle storage?

Yes, you can! 10x20 storage units are an extremely popular choice when selecting storage for vehicles. These units are ideal for most sedans, SUVs, and pickup trucks. They're also a great storage solution for cars, small trucks, motorcycles, ATVs, and small trailers.

If you're looking for vehicle self-storage, here are a few things to consider:

• Drive-Up Access: You need to select a 10x20 that has direct drive-up accessibility
• Height Clearance: Most units are 8 feet high, so lifted trucks may not fit
• Climate Control: For classic cars or luxury vehicles, you may want to up your budget and rent indoor vehicle storage that is climate-controlled

While you may want to opt for a smaller size to save money, there is definitely a difference between a 10x15 storage unit vs 10x20 storage unit. Compact cars can technically fit in the smaller size, but there will be no additional room to move around your vehicle. Because of that, we do not recommend a 10x15 when searching for vehicle storage units.

Who is a 10x20 storage unit best for?

If you're seeking a lot of extra space, then a 10x20 storage unit is right for you! You should consider renting one if you're (a):

• Renovating: If you're going through a large-scale home renovation, these units are great because they can store the contents of a 3-4 bedroom home
• Small Business Owner: Your office may not be large enough, so a 10x20 can house inventory overflow, office equipment, documents, and shelving. 10x20 units are excellent for e-commerce shop owners (think Etsy!). If you're working out of your home, you may not have room for your supplies and inventory. Our Business Storage 101 guide provides even more insight on choosing the right unit.
• Contractors & Tradespeople: Stash away your tools and supplies.
• Vehicle Owners: We've already mentioned it, but these units are excellent for storing vehicles.
• Military Personnel: If you're on extended leave or long-term deployment, a 10x20 is optimal for household and personal storage needs.
• Living with Roommates: Use a 10x20 when combining storage from multiple people (your roommates!). Need cheap storage? Split the unit rent, too.

How much does a 10x20 storage unit cost?

The price of a storage unit is dependent on a range of factors, including the location, facility amenities, unit features, and time of year. Fluctuations in price may be based on:

• Location: Prices are typically higher in major cities, along well-traveled highways, and other booming areas
• Climate Control, Heated, or Air Cooled
• Ground floor versus units that require stairs or an elevator to get to
• Seasonality (peak storage season is May through September, and price may be higher due to increased demand)
• Promotions the self-storage facility offers, such as discounted web rates, online promotions, referral programs, and military discounts

What is the best way to organize 10x20 storage?

Efficient organization will help you maximize space, protect your items, and make accessibility easier. Here are some of our top tips:

• Plan Ahead: Make a layout of where you plan to place your items, especially your large boxes and furniture. Also, plan to group like items together (e.g. kitchenware, seasonal decor, office supplies, etc.)
• Load Largest Items First: Put your furniture, mattresses, and appliances in your unit first. If possible, store your sofa vertically to save floor space.
• Use Uniform Boxes: This will lead to easier stacking and better stability. Also, don't forget to label all sides of the boxes with the content.
• Leave a Center Aisle
• Use Freestanding Shelving 
• Elevate: Use pallets or boards to keep good furniture, antiques, and boxes off the floor. This will help protect them from moisture.
