PPI Calculator
Calculate pixels per inch from screen size and resolution. PPI is density, not a picture-quality grade.
Result
108.8 PPI
A common desktop density, similar to many 27-inch 2560×1440 monitors. Sharpness still depends on how far you sit.
PPI is density, not a picture-quality score. Perceived sharpness also depends on viewing distance, scaling, and eyesight.
How this was calculated
- pixel_diagonal = √(horizontal² + vertical²). PPI = pixel_diagonal ÷ diagonal_inches.
- Pixel pitch (mm) = 25.4 ÷ PPI.
- The interpretation is a density description at typical desk distance, not a ranking of panel quality.
Limitations
- Perceived sharpness also depends on viewing distance, scaling, anti-aliasing, and eyesight.
- Two monitors with the same PPI can still look different because of coating, contrast, and processing.

A 24-inch monitor is usually the safer choice for shallow desks, 1080p gaming and lower cost. Choose 27 inches when you have enough viewing distance and can pair it with 1440p or 4K for a sharper, more spacious image.

A 27-inch monitor is usually the safer choice for average desks and sharper text, while a 32-inch model gives you more physical workspace if you can sit farther back. Resolution matters as much as diagonal size.

PPI
PPI means pixels per inch, a measure of how densely pixels are packed on a display. It is calculated from a screen’s physical size and native resolution, not a quality grade.

IPS (In-Plane Switching) is a type of LCD panel known for broad viewing angles and generally consistent image appearance. The IPS label alone does not indicate a monitor’s overall quality.

Refresh rate is how many times a display updates its image each second, measured in hertz (Hz). A higher rate can make motion look smoother when your device can provide enough frames.
