Screen Density (PPI) Calculator

Modern screens come in countless sizes and resolutions, making it difficult to understand how sharp a display truly is. Two screens may share the same resolution but look completely different depending on their physical size. This is where Pixels Per Inch (PPI) becomes critical. PPI determines how densely pixels are packed, directly affecting clarity, text sharpness, and UI precision. Designers, developers, and tech enthusiasts often struggle to calculate PPI manually using formulas. That’s why the Screen Density & PPI Calculator provides a fast, accurate solution. This advanced ppi calculator instantly computes screen density and total pixel count for any display.

How to Use This Screen PPI Calculator

Using the calculator is quick and precise:

• Enter the horizontal resolution (pixels)

• Enter the vertical resolution (pixels)

• Input the diagonal screen size in inches

• Click Calculate

• Instantly view the Pixels Per Inch (PPI) value

• See the total pixel count of the display

• Review screen density classification (standard vs high-density)

The calculator handles all mathematical calculations automatically for accurate results.

Frequently Asked Questions (FAQ)

1. What is a good PPI value for screens?
Generally, 300 PPI or higher is considered Retina or high-density.

2. Does higher resolution always mean higher PPI?
No. Screen size also affects PPI—larger screens spread pixels out more.

3. Can I use this for mobile screens?
Yes. The calculator works for phones, tablets, monitors, and TVs.

4. Is my data stored anywhere?
No. All calculations run locally in your browser.
