Sight Height Calculator

Formula

To calculate the sight height:

\[ SH = LOS - OC \]

Where:

\(SH\) is the sight height (inches)
\(LOS\) is the line of sight from the shooter's eye to the target (inches)
\(OC\) is the distance from the optic center to the rifle bore (inches)

What is Sight Height?

Sight height is the vertical distance between the center of the bore of a firearm and the optical axis of the sighting device, such as a scope. This measurement is crucial for accurate shooting as it affects the bullet’s point of impact, especially at different ranges. Properly calculating and adjusting the sight height can improve the accuracy of long-range shots.

Example Calculation 1

Let's assume the following values:

Line of Sight (LOS) = 20 inches
Optic Center to Rifle Bore (OC) = 2 inches

Using the formula:

\[ SH = 20 - 2 = 18 \text{ inches} \]

The Sight Height is 18 inches.

Example Calculation 2

Let's assume the following values:

Line of Sight (LOS) = 15 inches
Optic Center to Rifle Bore (OC) = 1.5 inches

Using the formula:

\[ SH = 15 - 1.5 = 13.5 \text{ inches} \]

The Sight Height is 13.5 inches.
