1. What is Aspect Ratio?

Definition: Aspect ratio is the proportional relationship between an image's width and height.

Purpose: It helps maintain consistent proportions when resizing images or videos across different devices and screens.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( AR \) — Aspect ratio (unitless)
• \( width\_resolution \) — Width in pixels
• \( height\_resolution \) — Height in 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

Details: Correct aspect ratio ensures images and videos display properly without stretching or distortion across different devices and platforms.

4. Using the Calculator

Tips: Enter the width and height in pixels (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 (HD), 4:3 (SD), 1:1 (square), and 21:9 (ultrawide).

Q2: How do I simplify an aspect ratio?
A: Divide both numbers by their greatest common divisor (GCD).

Q3: Why does my aspect ratio matter?
A: It affects how content fits on screens, preventing distortion or black bars.

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

Q5: How do I maintain aspect ratio when resizing?
A: Scale both dimensions by the same percentage or use aspect ratio constraints in editing software.
