How It Works:

Enter your screen's horizontal and vertical resolutions and diagonal size to calculate its Pixels Per Inch (PPI), Dot Pitch (DPI), screen dimensions, total pixels, and aspect ratio. Our calculator is versatile, supporting inputs in both inches and centimeters for global usability.


  • Enhanced Clarity: Understand the sharpness and clarity of your display.
  • Optimal Design: Tailor your designs and images for specific screen resolutions.
  • Informed Decisions: Choose the right monitor or TV based on precise PPI calculations.


Q: What is PPI?
A: PPI stands for Pixels Per Inch, a measurement of screen resolution and pixel density, indicating the sharpness of a display.
Q: How do I calculate PPI?
A: PPI is calculated using the formula below. For detailed calculations, use our PPI Calculator.

\[ \text{PPI} = \frac{\sqrt{\text{Horizontal Resolution}^2 + \text{Vertical Resolution}^2}}{\text{Diagonal Screen Size}} \]

Q: What PPI is considered high quality?
A: A PPI of 200 or above is generally considered high quality, offering clear and crisp visuals.
Q: How do you calculate pixels?
A: The total number of pixels is calculated by multiplying the horizontal resolution by the vertical resolution. For example, a 1920x1080 resolution has 1920 * 1080 = 2,073,600 pixels.
Q: What is the full form of PPI?
A: PPI stands for Pixels Per Inch, a measure of pixel density (sharpness) of a screen display.
Q: What is pixel size?
A: Pixel size refers to the physical dimensions of an individual pixel on a display. Smaller pixels result in a higher PPI and sharper image.
Q: How many PPI is a 24-inch monitor?
A: The PPI of a 24-inch monitor depends on its resolution. For a standard 1920x1080 monitor, the PPI can be calculated using the PPI formula provided earlier.
Q: What is the PPI of a 1920x1080 screen?
A: The PPI of a 1920x1080 screen varies based on the screen size. Use the PPI calculator to determine the exact value.
Q: What is the PPI resolution for 1920x1080?
A: The term "PPI resolution" is a bit misleading. PPI is a measure of pixel density, while 1920x1080 is the resolution. The density, or PPI, changes with screen size.
Q: What is the PPI of a 24 inch 1920x1200 monitor?
A: The PPI of a 24-inch 1920x1200 monitor can be calculated using the provided PPI formula, taking into account the resolution and screen size.
