How to Choose the Right Storage Unit Size

TGI Storage Bloomington · 6 min read

Choosing the wrong storage unit size is one of the most common mistakes Bloomington, IL storage renters make — either paying for space they don't need or cramming belongings into a unit that's too small and damaging them in the process.

Why Unit Size Matters More Than Most People Think

Most people approach self storage with one of two assumptions — either they rent the smallest unit available to save money and end up with belongings stacked dangerously to the ceiling with no room to access anything, or they rent the largest available unit to be safe and spend months paying for empty floor space. Neither approach is smart. Getting the right unit size from the start saves money, protects belongings, and makes the entire storage experience more practical and useful. TGI Storage Bloomington offers a range of unit sizes specifically designed to match the real storage needs of Bloomington, IL residents — from small personal storage to large household and business storage solutions.

The Complete Storage Unit Size Guide

Understanding what fits in each standard unit size is the foundation of making the right choice. Here is how the most common sizes break down in practical terms for Bloomington residents.

5x5 — The locker
About the size of a large closet. Ideal for boxes of documents seasonal décor a few pieces of sports equipment or the overflow from a single room in a small apartment.
5x10 — The studio
About the size of a large walk-in closet. Fits the contents of a studio apartment or dorm room — a mattress set small furniture boxes and seasonal items. Perfect for apartment dwellers and students.
10x10 — The one-bedroom
About the size of a small bedroom. Fits the contents of a one-bedroom apartment including furniture appliances and boxes. The most popular unit size for individual renters and small moves.
10x20 — The two-bedroom
About the size of a one-car garage. Fits the contents of a two to three bedroom home including major furniture appliances and a full moving load. Ideal for home sales and relocations.

How to Estimate What Size You Need

The most reliable way to estimate your unit size is to make a complete list of everything you plan to store before calling or visiting the facility. Walk through your home or the space you are clearing and write down every item — furniture pieces by name, number of boxes estimated, large equipment, and any oversized items like bikes, kayaks, or mattresses. Once you have that list in hand the team at TGI Storage Bloomington can help you identify the right size based on real experience with what fits. A few general guidelines: if you are storing the contents of a single room, a 5x10 is usually sufficient. If you are storing a full one-bedroom apartment, a 10x10 is the right starting point. If you are storing a full household during a home sale or renovation, a 10x20 or larger is typically needed.

Common Bloomington Storage Situations and the Right Unit Size

Illinois State University or Heartland student storing for summer: 5x5 or 5x10 depending on how much dorm or apartment furniture is being stored. Bloomington apartment dweller adding overflow storage: 5x5 for seasonal items and boxes; 5x10 for more substantial overflow. Bloomington homeowner renovating one or two rooms: 10x10 for a single room's furniture and contents; 10x15 or 10x20 for a larger renovation scope. Home seller staging and preparing to list: 10x15 to 10x20 depending on the size of the home and how much furniture is being cleared. Small business owner storing inventory or equipment: 10x10 to 10x30 depending on inventory volume and equipment size. Family receiving an estate or combining households: 10x20 or larger to accommodate furniture from multiple households simultaneously.

Tips for Getting Maximum Value From Any Unit Size

Regardless of which unit size you rent the way you load and organize it determines how much you can actually fit and how easily you can access what you need. Disassemble all furniture that can be taken apart — bed frames, tables, and shelving units take up dramatically less floor space when broken down. Use uniform boxes that stack cleanly and fill every box completely so nothing collapses under weight. Install a freestanding shelving unit along one wall to create multiple storage levels. Place large heavy items on the floor at the back, medium items in the middle, and frequently accessed items at the front. Label every box on the side so you can read labels when boxes are stacked. Leave a narrow aisle down the center of the unit so you can access items at the back without moving everything at the front.
