How to Choose the Right Vending Machine Size for Your Space
Headcount, foot traffic, and the width of your doorway all matter. Here's a practical way to pick a model.
Match the machine to daily foot traffic: a compact unit around 23 inches wide suits under 50 people, a mid-size unit fits 50 to 150, and a double-wide unit near 54 inches is right for campuses and high-traffic buildings.
Key takeaways
- Measure the doorway and the elevator, not just the wall.
- Under 50 people: a compact model is plenty.
- Over 150 people or 24-hour access: go wide, or add a second machine.
Start with daily foot traffic
The right question is not how big your building is — it's how many people walk past the machine each day. A 200-person office where everyone leaves for lunch may buy less than a 60-person gym open until midnight.
As a rule of thumb: under 50 daily users, a compact 23-inch-wide cooler covers demand. Between 50 and 150, a mid-size unit gives you the variety people expect. Above that, capacity — not selection — becomes the constraint.
Measure the path, not just the spot
Machines are delivered upright on a dolly. Before choosing a model, measure the narrowest doorway, the elevator depth, and any tight turns along the route.
Also confirm a standard grounded outlet within about six feet, and leave a few inches of clearance behind the unit for airflow.
When to add a second machine instead
Two machines in two locations almost always outsell one large machine in a single location, because convenience drives vending purchases more than selection does.
If your building has separate floors, wings, or a gym plus a lobby, splitting into two placements is usually the better call.
Frequently asked
- How much space does a vending machine need?
- Plan for the machine's footprint plus a few inches of rear clearance for airflow and roughly 30 inches of open floor in front so the door can swing.
- Do I need special electrical work?
- No. Standard smart coolers run on a normal grounded 110V household outlet.
