Enter the total column/grid width (px) and the overall width (px) into the Grid Percentage Calculator. The calculator will evaluate the Grid Percentage. 

Grid Percentage Formula

The following two example problems outline the steps and information needed to calculate the Grid Percentage.

GP = CW / OW * 100


  • GP is the Grid Percentage (%)
  • CW is the total column/grid width (px) 
  • OW is the overall width (px) 

To calculate the grid percentage, divide the column width by the overall width, then multiply by 100.

How to Calculate Grid Percentage?

The following steps outline how to calculate the Grid Percentage.

  1. First, determine the total column/grid width (px). 
  2. Next, determine the overall width (px). 
  3. Next, gather the formula from above = GP = CW / OW * 100.
  4. Finally, calculate the Grid Percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total column/grid width (px) = 150

overall width (px) = 720

GP = CW / OW * 100 = ?
