Enter the total screen length (in) and the total number of pixels into the Pixel Spacing Calculator. The calculator will evaluate the Pixel Spacing. 

Pixel Spacing Formula

The following two example problems outline the steps and information needed to calculate the Pixel Spacing.

PS = SL / #P


  • PS is the Pixel Spacing (inches/pixel)
  • SL is the total screen length (in) 
  • #P is the total number of pixels 

How to Calculate Pixel Spacing?

The following steps outline how to calculate the Pixel Spacing.

  1. First, determine the total screen length (in). 
  2. Next, determine the total number of pixels. 
  3. Next, gather the formula from above = PS = SL / #P.
  4. Finally, calculate the Pixel Spacing.
  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 screen length (in) = 15

total number of pixels = 960

PS = SL / #P = ?
