Lowest-Obstruction Clear-Height Calculator

Record every object above the intended court footprint. The lowest valid measurement—not the ceiling deck—becomes the constraint sent with your layout request.

Height measurements

Constraint result

Enter the measured heights, then calculate.

How to use the result

The tool finds the minimum of your measurements. It does not decide which attraction fits or replace local clearance rules; attach the result and a marked-up plan to the supplier review.
