Storage Lockers vs. Storage Units - Which Is Better?

Published on December 15, 2023

The primary factor that sets self-storage lockers apart from self-storage units is size. Storage lockers are roughly 20 square feet, while self-storage units can reach 300 square feet.

Self-storage units always offer walk-in access, regardless of their size. In contrast, storage lockers resemble secure cabinets, often arranged above, below, or next to lockers rented by other customers.

Both storage lockers and storage units provide secure storage space for various belongings. But which one suits you better?

This article will compare self-storage lockers and self-storage units—from their definitions, purposes, differences, pros and cons, and more.

Self-storage facilities have gained immense market popularity for addressing various storage needs, whether short-term or long-term.

Additionally, these storage facilities offer a secure space for individuals and businesses seeking extra space for items they cannot accommodate in their homes or offices.

As demand for them has grown, storage facilities have become more widespread and quickly expanded as an industry.

This comprehensive comparison outlines the key differences in amenities, benefits, and drawbacks both self-storage facilities offer.

Definition and Purpose of Storage Lockers

Storage lockers are typically used to store small items. For example, luggage, small boxes, documents, seasonal goods, and sports equipment.

You can usually find storage lockers as freestanding structures, like cabinets, attached to either a wall or the floor.

They are often arranged in rows, stacked on each other, or placed side by side within indoor storage facilities.

As the name suggests, indoor storage lockers are compact storage spaces typically made of metal or aluminum with lockable doors.

While storage lockers provide secure storage for a wide range of small belongings, they can also accommodate larger items if disassembled.

The key advantage of indoor storage lockers is their ability to offer a safe and accessible storage solution for individuals or businesses with modest storage needs.

A storage locker may not always offer climate control like a self-storage unit, but it usually has ventilation holes to take advantage of air conditioning.

Definition and Purpose of Storage Units

If storage lockers are like cabinets, self-storage units are like walk-in closets. They're like an extra home garage, only it needs renting.

Self-storage units are larger, enclosed spaces rented out to individuals or businesses for storing various items.

Self-storage units are typically metal or concrete and have a roll-up or swinging door.

You can typically find a self-storage unit in indoor storage facilities, but they're also found in warehouses and industrial parks in most cities.

Although they are generally used for storing business inventory, equipment, and records, various storage unit types can also store furniture, electronics, clothes, and vehicles like boats, ATVs, or cars.

In simpler words, everything you can store inside a storage locker, you can also stow in a storage unit—only you have to pay more.

It's also worth noting that storage units are often designed to hold more belongings.

Key Differences Between Storage Lockers and Storage Units

A storage locker and a storage unit are both secure options, but they generally differ in size, features, and cost of rent.

Storage lockers are smaller and more affordable than storage units. They are like secure cabinets, suitable for storing smaller items indoors, and may not have climate control or drive-up access.

They are ideal for your short-term storage needs.

Storage units are larger and more expensive than storage lockers. They are walk-in spaces that accommodate larger items, including furniture and vehicles.

They have specific features that make them ideal for long-term storage needs.

In the next sections, we'll look closer into these storage solutions.

Self-storage unit sizes tend to be bigger and more spacious than storage lockers on average.

Moreover, most storage units usually prohibit perishable foods, hazardous materials, plants, weapons, and other items, as this enclosed space caters to long-term storage facility needs.

In addition to understanding the features of a storage locker, here's everything you need to know about a typical self-storage unit.

Sizes and Dimensions of Storage Units

Self-storage units come in various sizes, typically starting at 50 square feet. However, the options are vast due to different storage companies' amenities and facility layouts.

Nonetheless, some common self-storage unit facility sizes fit within these ranges.

• Small Units: They're like small closets, roughly 5'x10' in size, perfect for storing items like boxes, small house furniture, or seasonal valuables.
• Medium Units: Similar to a standard bedroom, these self-storage facilities offer unit sizes from 10'x10' to 10'x15', making them a great option for the contents of a one or two-bedroom apartment.
• Large Units: These 10'x20' or larger unit sizes can hold the contents of a small house, vehicle, or business inventory, offering a garage-like storage solution for their owners.

Common Uses of Storage Units

A storage unit offers a safe, climate-controlled setting to safeguard your valuable business documents, household furniture, and extra inventory.

These units often come with extended access hours, granting you the flexibility to retrieve or store your belongings whenever and wherever you need them, including:

• Household Storage: Many individuals and families turn to storage units during various life transitions, such as moving to a new house.
• Vehicle Storage: A larger storage unit provides an enclosed and protected environment for cars, motorcycles, boats, or RVs.
• Business Storage: Businesses can use a storage unit to store surplus inventory, important documents, and specialized equipment, and even as a centralized distribution center to streamline operations.

Pros and Cons of Storage Units

Self-storage units and lockers are both popular choices for personal and business needs. This quick rundown will discuss their pros and cons at a glance.

Renting a self-storage unit can provide extra space for your belongings, but there are important factors to think about before you do.

PROS

• Ample space: The storage unit offers more space for various items and purposes.
• More features: Storage facilities and units have extra security and climate-controlled units to ensure the safety of your belongings.
• Availability: You won't have to wait long for a self-storage unit to become available because they are widely available in most cities in the United States.
• Versatility: Storage units come in an extensive range of sizes and dimensions, accommodating everything from small furniture to large vehicles.
• Long-term storage: A self-storage unit offers flexibility and security for your belongings, whether you're storing seasonal items, heirlooms, or the contents of an entire house or property.

CONS

• Transport: You might need a moving truck to transport your belongings to the self-storage unit, which can be time-consuming, costly, and difficult.

Security and Safety Features

It's best to ask yourself, "How crucial is your item's safety to you?"

A storage unit focuses on enhancing your storage security by offering additional features that regular storage lockers may lack, such as climate control, video surveillance, and security gates.

This is a huge difference. However, a storage locker typically has vents on its doors to ensure proper airflow—preventing dampness and storing your documents safely.

Unlike indoor climate-controlled units, ventilation from indoor lockers is only suitable for short-term storage.

Cost and Affordability

What is your budget for your storage rent?

Storage lockers are less expensive than storage units but offer less space and features.

Cost is a significant factor when choosing a storage facility, and several factors can influence it. Some facilities require a minimum storage duration, affecting the overall value of the facility.

A single locker costs as little as $5 monthly compared to a storage unit, which costs $70.

Although month-to-month options often offer more affordability, it's essential to consider additional fees.

Also, be mindful of potential late or missed payment fees to avoid unexpected expenses or the risk of losing your unit and boxes full of valuable items.
