What Size Self-Storage Unit Do You Need in Mount Joy, Elizabethtown, or Marietta?

Scott Garber • July 21, 2026

Choosing a storage unit can feel like guesswork. You do not want to pay for empty space, but you also do not want to arrive on moving day and discover that your sofa, boxes, or business inventory will not fit. The right size gives you enough room for your belongings, a safe path to reach them, and a little flexibility when your plans change.



Garber Self Storage offers a range of mini-storage sizes in Mount Joy, Elizabethtown, and Marietta. Because the available dimensions vary by property, the best approach is to start with what you plan to store, then compare that list with the options at the location most convenient for you.

Start With What You Are Actually Storing

Before comparing unit dimensions, make a simple inventory. Count your boxes, list the largest furniture pieces, and measure anything that could be difficult to position through a doorway. A sofa, dining table, mattress, tool chest, mower, or shelving unit can determine the size you need more quickly than the number of boxes.


A photo inventory can help, too. Ready.gov recommends maintaining a detailed record of your property, which is useful for insurance and also gives you a practical way to plan your storage layout. Take a few wide photos of each room, then note which items are going into storage.



Decide whether you need frequent access. If you will retrieve holiday decorations, business supplies, or sports equipment throughout the year, include space for a center aisle. If the unit will stay packed until a move is complete, you can usually use the floor area more tightly.

Storage Unit Sizes at a Glance

Storage companies often describe units by floor dimensions, but the number alone does not tell the whole story. Ceiling height, door width, furniture shape, shelving, and packing technique all affect the usable capacity. The guide below is a practical starting point, not a guarantee that every item will fit.

Sizing Guide

Storage Unit Size Comparison

Compare standard storage dimensions, total square footage, and typical capacities to find the best fit for your needs.

Unit size Floor area Useful starting point
5x8 40 sq. ft. Boxes, seasonal items, dorm contents, and small furniture
6x10 60 sq. ft. One room, tools, shelving, or small-business overflow
8x8 64 sq. ft. Studio or room contents, a mattress, dresser, and boxes
8x10 80 sq. ft. Furnishings from many one-bedroom apartments
9x9 or 10x10 81-100 sq. ft. A larger one-bedroom or compact two-bedroom setup
8x12 or 6x19 96-114 sq. ft. Furniture, appliances, long items, or equipment
8x16 128 sq. ft. A two-bedroom home or multi-room renovation
8x20 160 sq. ft. A two-to-three-bedroom move or business inventory

Planning Note: Actual fit depends on door dimensions, ceiling height, furniture shape, shelving, box sizes, and the amount of access space you leave. Not sure which size fits? Call Garber Self Storage at 717-653-1988 and describe your largest items, box count, and access needs.

Use Vertical Space Without Overpacking

A well-organized unit can hold much more than a unit filled without a plan. Disassemble tables and bed frames when possible, store hardware in labeled bags, and place flat pieces along a wall. Use sturdy, similarly sized boxes so they stack safely. Put heavier boxes on the bottom and keep fragile or frequently used items near the front.



Shelving can make a smaller unit more useful for business inventory, records, tools, and seasonal bins. Still, do not stack items so tightly that you cannot inspect them or reach what you need. A slightly larger unit may cost more each month, but it can save you from unloading half the space every time you need one box.

Match the Unit to Your Situation

Moving or Preparing a Home for Sale

For a short transition, start with the number of furnished rooms you are clearing. A smaller unit may handle selected furniture and boxes from one room. An 8x10, 9x9, or 10x10 can be a better starting point for the contents of a one-bedroom apartment, depending on the amount of furniture. An 8x16 or 8x20 may suit a larger household move when items are carefully packed.



Leave a little extra room if your closing dates are uncertain. Moves often create last-minute boxes, cleaning supplies, or furniture that was not included in the original plan.

Renovating, Decluttering, or Storing Seasonal Items

You may not need a large unit when you are clearing one room for flooring, painting, or a remodeling project. A 5x8, 6x10, or 8x8 can provide useful breathing room for boxes, chairs, small tables, décor, and equipment. For a kitchen or multi-room renovation, an 8x10 or larger unit may be easier to load and organize.



Seasonal storage works best when you group items by use. Keep holiday decorations together, place lawn and garden items in another zone, and label bins on more than one side. This lets you rotate items without disturbing everything else.

Business, Contractor, or Hobby Storage

For business use, floor area is only part of the decision. Think about how often you will load or unload, whether shelving will be installed, and whether long equipment needs a clear path. A 6x19 layout may work well for long items, while an 8x16 or 8x20 provides more room for inventory, tools, displays, or project materials.



Do not assume the smallest possible unit is the least expensive choice over time. If cramped storage slows down every visit or causes you to buy duplicate supplies because you cannot find what you have, a more workable layout may offer better value.

Compare Locations and Access Before Reserving

Convenience matters when you will visit your unit regularly. Garber's Mount Joy storage options on Milton Grove Road include mini-storage along with larger vehicle bays. The Fairview Street mini-storage location also offers several compact and mid-size options. In Elizabethtown, available unit types range from mini-storage to large bays, while the Marietta self-storage location includes sizes such as 6x10, 6x12, 6x19, 8x8, 8x12, 8x16, 9x9, and 10x10.



Review the access hours and current availability for the specific property you are considering. A unit close to home or work may be more useful than a slightly cheaper space that adds time to every visit.

Avoid These Common Sizing Mistakes

  • Renting only for today's pile. If you are moving, renovating, or growing a business, allow for the items that may be added next week.
  • Forgetting the access aisle. A tightly packed unit can hold more, but it may be frustrating when the item you need is in the back.
  • Ignoring door and furniture measurements. Measure wide, tall, or awkward pieces before choosing a unit.
  • Packing items that should not be stored. Review your rental agreement and ask the facility about prohibited items. The U.S. Environmental Protection Agency provides guidance for safely managing household hazardous waste such as paints, oils, cleaners, and other products that may be toxic, corrosive, ignitable, or reactive.

A Simple Five-Step Way to Choose

  1. List the large items and estimate the number of boxes.
  2. Measure furniture, equipment, and other awkward pieces.
  3. Decide whether you need an aisle or regular access.
  4. Compare your list with the sizes available at your preferred location.
  5. Ask the local team to confirm the fit before you reserve.

Storage Unit FAQs

Frequently Asked Questions

Get quick answers to common questions about storage unit sizes, layout differences, and choosing the right space for your belongings.

Can a queen mattress fit in a 5x8 storage unit?

A queen mattress is about 5 feet wide and a little under 7 feet long, so it may fit depending on the doorway, interior dimensions, and how it is positioned. The rest of your furniture and boxes may make a larger unit more practical. Measure the mattress and confirm the unit's door opening before move-in.

What size unit is usually suitable for a one-bedroom apartment?

An 8x10, 9x9, or 10x10 is often a useful starting range for a one-bedroom apartment, but the right choice depends on furniture volume, appliances, box count, and whether you need an aisle. A minimally furnished apartment may fit in less space, while a full apartment may need more.

Is an 8x10 the same as a 10x8?

The floor area is the same at 80 square feet, but the layout can feel different. Door placement and the direction of the longer wall can affect how you arrange a sofa, mattress, shelving, or long equipment.

Should I choose a larger unit for long-term storage?

Often, yes. Long-term storage is easier when you can leave a walkway, keep boxes off the floor on shelving or pallets, and inspect your belongings without moving everything. The smallest possible unit may work for a sealed move, but it may not be comfortable for repeated access.

Can I change unit sizes later?

Availability varies, so ask before you reserve. Moving to another unit may be possible, but choosing carefully at the start can save you the work of unloading and repacking.
