Choosing a storage unit sounds simple until you actually start looking at dimensions like 5x10, 10x15, or 10x20 and trying to picture how much stuff will fit inside. The good news is that you usually do not need to calculate it perfectly. A little planning can get you very close to the right size without paying for a lot of unused space—or discovering halfway through a move that your unit is too small.
At Charlevoix Mini Storage, we offer a range of drive-up, hallway, climate-controlled, and larger specialty storage spaces across four locations in Charlevoix. This guide explains how common storage unit sizes compare, what each size is typically useful for, and what else you should consider before reserving.
For a quick visual comparison, you can also use our Storage Unit Size Guide, or check live storage unit availability and pricing at all four locations.
The best way to choose a storage unit is to think about both the amount of property you are storing and how you want to access it. Two people with the same amount of furniture may choose different unit sizes because one plans to pack everything tightly for six months while the other needs an aisle to reach boxes throughout the year.
Before reserving, make a quick list of your largest items: beds, sofas, dining tables, appliances, shelving, outdoor furniture, business inventory, and any unusually long or bulky pieces. Those items usually determine the minimum footprint you need. Boxes and smaller belongings can then be stacked around them.
A 5x10 storage unit is a useful starting point for smaller storage needs. At approximately 50 square feet, it offers roughly the floor area of a large walk-in closet, although the actual usable space depends on the unit layout and how efficiently you pack.
A 5x10 can also work well when you simply need to clear out a garage, closet, spare bedroom, or seasonal property without storing an entire household.
Our Old Norwood Road facility offers both drive-up and hallway storage options, while availability at each location changes throughout the year.
A 10x10 unit gives you approximately 100 square feet of floor area and is one of the most versatile storage sizes. The square layout generally makes it easier to arrange furniture along the walls while stacking boxes vertically.
For someone moving between homes, remodeling several rooms, or storing the contents of a smaller apartment, a 10x10 is often a practical middle ground.
A 10x15 unit provides approximately 150 square feet and gives you substantially more flexibility for larger furniture and appliances.
This size can be a good option for a one- to two-bedroom move, depending on how much furniture you own and how tightly you intend to pack.
If you expect to visit your unit regularly, consider leaving a narrow aisle through the center rather than filling every square foot from front to back. That usually makes a slightly larger unit much easier to live with.
A 10x20 provides approximately 200 square feet of floor area and is one of the most useful sizes for a larger move, significant renovation, or long-term household storage.
Drive-up units are particularly convenient at this size because a moving truck or vehicle can be positioned close to the unit, reducing the distance heavy furniture needs to be carried.
You can browse drive-up options at our US-31 South facility and Old Norwood Road facility.
Large storage units are useful when you have substantially more household contents, bulky business inventory, a major remodeling project, or simply need room to organize rather than pack everything tightly.
The advantage of a larger unit is not just additional square footage. It also gives you more freedom to create aisles, separate belongings by room, and keep frequently used items near the entrance.
Availability of larger sizes varies, so the easiest way to see what is currently open is our live availability page.
Unit size is only one part of the decision. You should also consider what you are storing.
Climate-controlled storage maintains a more stable interior environment than standard outdoor-access storage and can be a particularly attractive option for belongings such as:
Our US-31 South Business Park offers ground-level interior climate-controlled storage in multiple sizes with convenient parking nearby.
For substantially larger needs, our Stover Road facility offers premium climate-controlled spaces of nearly 600 square feet with tall roll-up doors, high ceilings, lighting, electrical power, and 24/7 access.
A slightly smaller drive-up unit can sometimes be more convenient than a larger interior unit, depending on what you are storing.
With drive-up storage, you can pull directly to the unit door. That can make a big difference when moving sofas, appliances, heavy boxes, tools, or business inventory.
Interior storage may be preferable when climate control is more important than vehicle-side loading.
Neither option is automatically better. The right choice depends on your belongings and how you expect to use the unit.
Measure anything that cannot easily be disassembled. A large sectional, mattress, workbench, cabinet, or dining table may determine the minimum unit dimensions you need.
Storage units have much more usable volume than floor area alone suggests. Sturdy boxes and totes can often be stacked safely, and shelving can make frequently used items easier to reach.
Packing a unit completely full works when you do not expect to touch anything for months. If you plan to retrieve items throughout the year, sacrificing a little storage density for an aisle can save a lot of frustration.
Saving a small amount each month is not worthwhile if you end up needing a second unit or have to unpack half the unit every time you need something from the back.
Storage inventory changes constantly. Your ideal size may not always be open, while a slightly different size may be available immediately.
Our Rent Storage page shows current unit sizes, pricing, availability, and waiting-list options across all four Charlevoix Mini Storage facilities.
Storage needs in Northern Michigan are often seasonal. Patio furniture, outdoor equipment, household overflow, cottage contents, recreational gear, and belongings from seasonal moves can consume a surprising amount of space at home.
A storage unit can make it easier to reclaim garage or basement space while keeping those belongings nearby when the season changes again.
Because our four facilities are all located in south Charlevoix, customers can choose between different unit types without having to travel across the area. You can compare addresses, access types, and directions on our Locations & Directions page.
As a general starting point:
These are only guidelines. Furniture sizes, packing style, unit dimensions, and the amount of access space you leave can all change what actually fits.
You do not have to guess. Use our Storage Unit Size Guide for a visual comparison, or contact our local office and tell us what you are planning to store.
We can help you compare available sizes and determine which of our four Charlevoix locations makes the most sense for your needs.
