Garage Storage Capacity Planner

How to calculate garage storage capacity?

Calculating your total storage potential depends on the physical relationship between your available linear wall length and the vertical height used for shelving. By utilizing the full vertical span of your garage, you can multiply your storage volume without encroaching on valuable floor space.

Volume = Linear Wall Feet × Shelf Depth × Tiers

Using the Storage Planner: an example

Imagine a standard 20x20 ft double garage with 10 ft ceilings and 24-inch (2 ft) deep shelving units. To maximize efficiency, we focus on the perimeter walls while accounting for architectural obstructions like garage doors and electrical panels.

Step-by-step calculation:

1. Calculate perimeter wall area (800 sq ft based on total height).
2. Subtract 25% for garage doors and entryways (600 sq ft usable).
3. Determine shelf volume for 3 tiers to optimize vertical space.
4. Subtract vehicle footprint to find the remaining open floor space.

Frequently Asked Questions

Is overhead storage safe?
Yes, provided you mount the racks directly into ceiling joists and strictly adhere to the manufacturer's weight limits. Avoid using drywall anchors for heavy storage.

What is the ideal height for wall-mounted bins?
Bins for frequently used items should be placed between 3 and 5 feet high. Seasonal items or long-term storage bins can be placed higher, typically above 6.5 feet.

How much clearance is needed between a car and shelving?
We recommend maintaining a minimum clearance of 30 to 36 inches. This ensures you can comfortably open car doors and walk between the vehicle and the shelving units without obstruction.
