### Introduction

The Screen Size Calculator Comparison is a versatile tool for users who want to compare screen sizes with different aspect ratios. Whether you are deciding between displays or planning a home theater setup, this calculator allows you to input the diagonal size and choose from various aspect ratios to see how they affect the screen dimensions.

### Formula

The calculation involves using the Pythagorean theorem to find the width and height of the screen based on the selected aspect ratio and diagonal size. The Pythagorean theorem ensures that the width, height, and diagonal size form a right-angled triangle.

### How to Use

**Diagonal Size (inches):**Enter the diagonal size of the screen.**Aspect Ratio:**Select the desired aspect ratio from the dropdown menu.- Click the “Calculate” button to obtain the width and height of the screen for comparison.

### Example

Consider a screen with a diagonal size of 40 inches and compare its dimensions for two different aspect ratios: 16:9 and 4:3. Input these values into the calculator to see how the aspect ratios affect the screen dimensions.

### FAQs
