Enter the total number of horizontal lines displayed and the time (sec) into the Calculator. The calculator will evaluate the Horizontal Scan Rate.

## Horizontal Scan Rate Formula

HSR = HL / T

Variables:

- HSR is the Horizontal Scan Rate (lines/sec)
- HL is the total number of horizontal lines displayed
- T is the time (sec)

To calculate the Horizontal Scan Rate, divide the total number of lines by the time.

## How to Calculate Horizontal Scan Rate?

The following steps outline how to calculate the Horizontal Scan Rate.

- First, determine the total number of horizontal lines displayed.
- Next, determine the time (sec).
- Next, gather the formula from above = HSR = HL / T.
- Finally, calculate the Horizontal Scan Rate.
- 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 number of horizontal lines displayed = 800

time (sec) = 5
