1. What is a Display Calculator?

Definition: This calculator estimates the pixel resolution of a display based on its physical dimensions and pixel density.

Purpose: It helps designers, developers, and tech enthusiasts understand display capabilities and plan screen layouts.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Size — Physical dimension (width or height) in inches
• PPI — Pixels per inch (pixel density)
• Resolution — Number of pixels in that dimension

Explanation: Multiply each physical dimension by the pixel density to get the resolution in pixels.

3. Importance of Display Calculation

Details: Understanding display resolution helps in creating properly sized graphics, responsive designs, and choosing appropriate screen sizes.

4. Using the Calculator

Tips: Enter the screen width and height in inches, and the PPI (default 96). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is PPI?
A: PPI stands for Pixels Per Inch, a measure of screen pixel density.

Q2: What's a typical PPI value?
A: Standard monitors are often 96 PPI, while smartphones may be 300+ PPI.

Q3: How do I find my screen's PPI?
A: Check manufacturer specs or divide resolution by physical size.

Q4: Does this account for aspect ratio?
A: Yes, by entering separate width and height values.

Q5: Can I use this for print calculations?
A: No, print uses DPI (dots per inch) which works differently.
