How do I calculate crosshair size on a phone?

Enter the phone's display diagonal and pixel resolution, the crosshair span in pixels, and your normal viewing distance. The calculator estimates physical width, screen coverage, and visual angle.

What does crosshair visual angle mean?

Visual angle describes how large the crosshair appears to your eye. The same physical crosshair appears larger when the phone is closer and smaller when it is farther away.

Is the same pixel size equal on every phone?

No. The physical size depends on pixel density. A 24-pixel crosshair appears smaller on a denser display and larger on a lower-density display.

What is the best mobile crosshair size?

There is no universal best size or visual angle. Use the estimate as a comparison tool, then test visibility without covering the target or nearby detail.

How big is that crosshair to your eye?

Pixels alone do not describe apparent size. Enter your display, crosshair span, and normal viewing distance to estimate physical size, screen coverage, and visual angle.

WHY PIXELS CHANGE

The same number can look different on every display.

01 / DENSITY

Pixel density changes physical size

A 24-pixel span is physically smaller when those pixels are packed more tightly. The calculator estimates pixels per inch from the diagonal and native resolution.

02 / COVERAGE

Screen percentage helps comparison

Width coverage shows how much of the display the crosshair occupies. It is useful when moving a setup between phones with different resolutions.

03 / DISTANCE

Distance changes apparent size

Visual angle combines physical size with viewing distance. Moving the same phone closer makes the crosshair appear larger without changing a single game setting.

04 / TESTING

Numbers are a starting point

Readability also depends on color, outline, scene contrast, motion, and the game itself. Test the result rather than treating one number as universal.

QUICK ANSWERS

Crosshair size
questions.

How is physical size calculated?

The tool estimates display width from the diagonal and resolution aspect ratio. It then converts crosshair pixels through the estimated pixel density into millimeters.

What does visual angle mean?

Visual angle estimates how large the crosshair appears to your eye. It is calculated from the physical crosshair size and the distance between your eyes and the phone.

Is this exact for every device?

It is an estimate. Rounded manufacturer dimensions, display scaling, browser zoom, viewing-distance measurement, and game rendering can change the real result slightly.

Does this replace the iPhone app?

No. It only compares physical and apparent scale. The app provides recommendations, presets, customization, previews, favorites, and copy-ready settings.
