Enter the height of lead strips (in) and the distance between strips (in) into the Grid Ratio Calculator. The calculator will evaluate and display the Grid  Ratio. 

Grid Ratio Formula

The following formula is used to calculate the Grid  Ratio. 

GRD = HLS / DS

  • Where GRD is the Grid Ratio
  • HLS is the height of lead strips (in) 
  • DS is the distance between strips (in) 

How to Calculate Grid Ratio?

The following example problems outline how to calculate Grid Ratio.

Example Problem #1:

  1. First, determine the height of lead strips (in). 
    • The height of lead strips (in) is given as: 5.
  2. Next, determine the distance between strips (in). 
    • The distance between strips (in) is provided as: 6.
  3. Finally, calculate the Grid Ratio using the equation above: 

GRD = HLS / DS

The values given above are inserted into the equation below and the solution is calculated:

GRD = 5 / 6 = .833


Example Problem #2: 

For this problem, the variables required are provided below:

height of lead strips (in) = 6

distance between strips (in) = 10

Test your knowledge using the equation and check your answer with the calculator above.

GRD = HLS / DS = ?
