The most common single-tier locker measures approximately 12 inches wide by 12 inches deep by 60, 66, or 72 inches tall. Multi-tier configurations typically divide the same frame into 2, 3, 4, 5, or 6 compartments. Exact sizes vary by manufacturer.

How Do You Choose the Right Locker Size?
Choosing the right locker size typically starts with user needs, moves to space planning, then finishes with material selection. Measure the bulkiest item that needs to fit inside, then add an allowance for ventilation and access (allowances vary by locker type). Plan for growth and flexibility for added tiers or wider units over time. Browse the ASI Storage Solutions locker catalog to compare configurations for schools, gyms, offices, and industrial facilities.
