1. What is a Display Size Calculator?

Definition: This calculator determines the diagonal screen size based on the width and height measurements of a display.

Purpose: It helps users verify screen size specifications or calculate the diagonal when only width and height are known.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( Diagonal \) — Screen size (inches)
• \( Width \) — Display width (inches)
• \( Height \) — Display height (inches)

Explanation: The diagonal is calculated as the square root of the sum of the squared width and height measurements.

3. Importance of Accurate Display Measurement

Details: Knowing the exact diagonal size helps when comparing displays, setting up viewing distances, or replacing screens.

4. Using the Calculator

Tips: Enter the width and height in inches (measured from corner to corner). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for all display types?
A: Yes, the calculation works for any rectangular display (LCD, LED, OLED, CRT, etc.).

Q2: Should I include the bezel in measurements?
A: No, measure only the visible screen area from corner to corner.

Q3: What if my display isn't rectangular?
A: This calculator only works for standard rectangular displays with right angles.

Q4: Can I use centimeters instead of inches?
A: Yes, but be consistent - use the same unit for all measurements.

Q5: Why is my calculated diagonal different from the advertised size?
A: Manufacturers sometimes round sizes, or your measurements might include slight curvature or bezels.
