How to calculate ceiling grid main runner
This calculator finds how many main runners are needed for a suspended ceiling grid by dividing the ceiling area (or length) by the coverage of each runner.
How the calculation works
Main runners needed = Total requirement ÷ Coverage per runner (rounded up). Main runners typically run the long dimension of a ceiling grid at a standard spacing.
Example
A ceiling requiring 60 linear feet of main runner coverage, with runners covering 12 feet each: 60 ÷ 12 = 5 runners.
