When you only need a little extra storage space, a smaller unit can be the perfect solution. But choosing between a 5x5 storage unit and a 5x10 storage unit can be tricky if you have never rented storage before.

Both sizes are popular for apartment renters, students, homeowners, seasonal storage, and anyone who needs extra room without renting a large unit. The biggest difference is how much flexibility you need. A 5x5 unit is great for boxes, decor, and small items. A 5x10 unit gives you enough room for small furniture, a mattress set, and more household overflow.

If you are comparing small storage units in Lehi, this guide will help you understand what fits in each size and which option makes the most sense for your situation.

Quick Comparison: 5x5 vs 5x10 Storage Units

A 5x5 storage unit is about the size of a small walk-in closet. A 5x10 storage unit is about the size of a larger walk-in closet or half of a small bedroom.

Here is the simplest way to compare them:

• A 5x5 storage unit is best for: Boxes, totes, seasonal decor, small furniture, sports gear, and closet overflow.
• A 5x10 storage unit is best for: Studio apartment furniture, a mattress set, small couch, dresser, boxes, and larger apartment overflow.

If you are only storing items you could fit in a closet, a 5x5 may be enough. If you need to store furniture or the contents of a small room, a 5x10 is usually the better fit.

What Fits in a 5x5 Storage Unit?

A 5x5 storage unit gives you about 25 square feet of floor space. While that may sound small, it can hold more than many people expect when packed carefully.

A 5x5 unit can typically fit:

• 8–12 medium boxes or totes
• Seasonal decor
• Small shelves
• Nightstands
• Lamps
• Small chairs
• Sports gear
• Camping gear
• Holiday decorations
• Business files or records
• Dorm room overflow
• Extra closet items

This size works well when you need to free up space at home but are not storing large furniture.

Best Uses for a 5x5 Storage Unit

A 5x5 storage unit is a smart choice for small-space storage needs.

Apartment Closet Overflow

If your apartment closets are packed, a 5x5 unit can act like an off-site closet. It is ideal for items you do not need every day, such as winter clothes, holiday decorations, extra bedding, small appliances, and outdoor gear.

Seasonal Storage

Utah seasons come with a lot of gear. Skis, snowboards, camping supplies, patio cushions, holiday decorations, and sports equipment can take over a closet or garage quickly. A 5x5 unit helps keep seasonal items out of your living space until you need them.

Student Storage

A 5x5 unit can be a practical choice for students who need to store dorm items, books, small furniture, bedding, or boxes between semesters.

Business Storage

Small business owners may use a 5x5 unit for records, marketing materials, samples, tools, or overflow supplies. It is not a warehouse, but it can be useful for keeping business items organized and separate from home.

When a 5x5 Unit May Be Too Small

A 5x5 unit is not ideal for most furniture storage. You may be able to fit a small chair, nightstand, or narrow shelving unit, but it usually will not comfortably hold large items.

A 5x5 may be too small if you need to store:

• A couch
• A queen or king mattress set
• A dining table
• Large dressers
• Appliances
• Multiple rooms of furniture
• Large garage tools
• Patio furniture sets

If your storage list includes furniture, especially a mattress or sofa, you should strongly consider a 5x10 storage unit instead.

What Fits in a 5x10 Storage Unit?

A 5x10 storage unit gives you about 50 square feet of floor space, which is double the footprint of a 5x5 unit. That extra length makes a major difference.

A 5x10 unit can typically fit:

• Queen mattress set
• Small couch or loveseat
• Dresser
• Nightstands
• Small dining table and chairs
• Several boxes or totes
• Lamps and decor
• Bicycles
• Small bookshelves
• Office chair and desk
• Studio apartment contents

For many Lehi renters, a 5x10 storage unit is the smallest size that can realistically handle both boxes and furniture.

Best Uses for a 5x10 Storage Unit

A 5x10 storage unit is still compact, but it gives you much more flexibility than a 5x5.

Studio Apartment Storage

If you are storing the contents of a studio apartment, a 5x10 may be a good fit. You can usually fit a mattress, small sofa, dresser, boxes, and a few household items if everything is packed efficiently.

Small Apartment Moves

If you are moving between apartments in Lehi and need temporary storage, a 5x10 unit can help bridge the gap. It is especially useful if your move-in and move-out dates do not line up perfectly.

Furniture Storage

A 5x10 unit is a better option for small furniture. It can hold a mattress set, small couch, dresser, desk, or small dining set, depending on the shape and quantity of items.

Decluttering Before Selling or Renting

If you are preparing a home or apartment for photos, showings, or guests, a 5x10 can hold extra furniture, boxes, decor, and personal items while keeping your space clean and open.

When a 5x10 Unit May Be Too Small

A 5x10 storage unit can hold a lot, but it is still a small unit. If you are storing the contents of a full one-bedroom apartment with larger furniture, you may feel cramped.

A 5x10 may be too small if you need to store:

• A full one-bedroom apartment
• Large sectional sofa
• Multiple mattress sets
• Large appliances
• A full dining room set
• Large garage equipment
• Items from multiple rooms
• Furniture that cannot be stacked or disassembled

If you need to store most of a one-bedroom apartment, a 10x10 storage unit may be a better choice.

How to Decide Between a 5x5 and 5x10 Storage Unit

The easiest way to choose is to separate your items into two groups: boxes and furniture.

If you mostly have boxes, totes, seasonal items, and small gear, a 5x5 may be enough. If you have furniture, a mattress, or larger household items, choose a 5x10.

Here are a few practical decision points.

Choose a 5x5 Storage Unit If:

• You only need closet-style overflow
• You are storing boxes and totes
• You have seasonal decor or sports gear
• You do not have large furniture
• You want the smallest practical storage option
• You are storing dorm or office overflow

Choose a 5x10 Storage Unit If:

• You need to store a mattress
• You have small furniture
• You are moving out of a studio apartment
• You need temporary apartment storage
• You want extra room to organize items
• You may add more items later

Think About Access, Not Just Space

A smaller unit may technically fit your items, but that does not always mean it is the right choice.

If you need to access your items often, the larger unit may be more convenient. A tightly packed 5x5 can be frustrating if the item you need is in the back. With a 5x10, you may have more room to create sections, stack boxes more safely, and reach items without unloading the whole unit.

If you are storing items short term and do not need to access them until move-out, a tighter fit may be fine. If you are using the unit as ongoing overflow storage, give yourself a little extra space.

Packing Tips for Small Storage Units

Small storage units work best when packed efficiently.

Use boxes or totes that are similar in size so they stack neatly. Label each box on at least two sides. Place heavier boxes on the bottom and lighter items on top. Disassemble small furniture when possible. Store long items vertically if safe to do so.

For a 5x10 unit, place larger furniture against the back or side wall, then stack boxes in front. Keep items you may need soon near the front.

Avoid packing fragile items under heavy boxes or furniture. If you are storing wood furniture, electronics, documents, or delicate belongings, consider whether an indoor or temperature-controlled unit is a better fit.

Small Storage Units for Lehi Apartment Renters

Lehi continues to grow, and many local renters need extra room without upsizing their apartment. A small storage unit can help keep your home organized without forcing you to part with items you still use.

A 5x5 or 5x10 unit can be useful for:

• Seasonal clothing
• Outdoor gear
• Holiday decorations
• Extra kitchen items
• Small furniture
• Hobby supplies
• Sports equipment
• Moving boxes
• Keepsakes
• Business supplies

For apartment renters, the best storage unit is often the one that solves the immediate space problem without creating a bigger monthly expense than necessary.
