1. What is a Screen Resolution Ratio Calculator?

Definition: This calculator determines the aspect ratio of a screen resolution by comparing its width to height.

Purpose: It helps designers, developers, and video professionals understand the proportions of different screen resolutions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Ratio \) — Aspect ratio (unitless)
• \( Width \) — Horizontal resolution (pixels)
• \( Height \) — Vertical resolution (pixels)

Explanation: The width is divided by height to get the ratio, which is then simplified to common format (like 16:9).

3. Importance of Aspect Ratio

Details: Aspect ratio affects how content appears on screens, influencing design decisions for websites, videos, and applications.

4. Using the Calculator

Tips: Enter the width and height in pixels. Both values must be positive integers (typically 1 or greater).

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 4:3 (old TVs), 16:9 (HDTV), 16:10 (some monitors), and 21:9 (ultrawide).

Q2: How is this different from resolution?
A: Resolution is the pixel count (e.g., 1920×1080), while aspect ratio is the proportion (e.g., 16:9).

Q3: Why does the simplified ratio matter?
A: Simplified ratios (like 16:9) are easier to recognize and work with than decimal values (1.7778).

Q4: Can I calculate ratio from physical dimensions?
A: Yes, but you'd use inches/cm instead of pixels. This calculator focuses on pixel dimensions.

Q5: What if my resolution is portrait orientation?
A: The calculator works the same - it will show ratios like 9:16 for portrait 1080×1920.
