1. What is an Aspect Ratio Calculator?

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

Purpose: It helps designers, photographers, and videographers understand the proportional relationship between width and height of an image or screen.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( AR \) — Aspect ratio (dimensionless)
• \( W \) — Width (pixels)
• \( H \) — Height (pixels)

Explanation: The width is divided by height to get the aspect ratio, which is then simplified to its lowest common denominator.

3. Importance of Aspect Ratio Calculation

Details: Correct aspect ratio ensures proper image display without distortion, maintains consistency across devices, and helps in responsive design.

4. Using the Calculator

Tips: Enter the width and height in pixels. Both values must be positive integers. The calculator provides both decimal and simplified ratio formats.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 16:9 (HDTV), 4:3 (standard TV), 1:1 (square), and 21:9 (ultrawide).

Q2: Why does aspect ratio matter?
A: It determines how content fits on screens and maintains proper proportions when resizing images or videos.

Q3: How do I simplify an aspect ratio?
A: Divide both width and height by their greatest common divisor (GCD).

Q4: Is aspect ratio the same as resolution?
A: No, resolution is the total pixel count (e.g., 1920×1080), while aspect ratio is the proportional relationship (e.g., 16:9).

Q5: Can I calculate aspect ratio from physical dimensions?
A: Yes, use the same formula with physical measurements (inches, cm, etc.) instead of pixels.
