Cooler Wall Planner: How Many Doors and How Big a Box
Enter the number of glass doors you want to see how long the cooler wall runs and how much floor the walk-in behind it takes.
Updated October 25, 2026
Cooler wall planner
Rough box size from the door count you want. Not an engineered layout.
Real door frames, end panels, panel thickness and the refrigeration system change the final dimensions. Exact sizes come from the door manufacturer's specification and a refrigeration load calculation for the box.
Why the cooler wall decides so much
The cooler wall is one of the most expensive parts of the store and one of the hardest to change. It sets where the back wall sits, how much floor the walk-in behind it takes, and where customers walk. That is why we size it early, alongside the floor plan, rather than fitting doors into whatever wall is left.
How the planner works
The planner multiplies your door count by the nominal door width to estimate the door run along the sales floor. It multiplies that run by the box depth for the walk-in footprint behind the doors, and by the height for interior volume. Real door frames, end panels and panel thickness add to these figures, so treat them as a starting point.
Planning the doors by category
A simple way to set the door count:
- List the categories you will sell cold: soft drinks, water, energy drinks, dairy, beer, and any others.
- Give each category the doors its sales justify. Beer and soft drinks usually take the most.
- Add up the doors, run the planner, and check the wall fits your floor plan.
- If it doesn't fit, decide whether to shrink a category, move some to reach-ins, or add a beer cave.
Depth and back stock
The depth of the box is about back stock. A deeper walk-in holds more product between deliveries but takes floor space from the stockroom and the store. Sizing it depends on your delivery schedule and sales volume, which is why the final size comes from a refrigeration load calculation, not a rule of thumb.
From plan to installed wall
We design walk-in coolers with refrigeration calculations and power requirements, and install the display door lines we carry, including Anthony and Styleline. See glass display doors and commercial walk-in coolers.
