1. What Is Aspect Ratio?

Aspect ratio is the proportional relationship between the width and height of an image or screen. It's expressed as two numbers separated by a colon (e.g., 16:9), representing width to height.

2. How To Calculate Aspect Ratio

The aspect ratio is calculated using the formula:

Where:

• \( Width \) — The width in pixels
• \( Height \) — The height in pixels

Explanation: The calculator simplifies the ratio by finding the greatest common divisor of the width and height values.

3. Common Aspect Ratios

Details: Common aspect ratios include 16:9 (widescreen), 4:3 (standard), 1:1 (square), 21:9 (ultrawide), and 3:2 (many digital cameras).

4. Using The Calculator

Tips: Enter the width and height in pixels. Both values must be positive integers greater than zero. The calculator will display both the decimal ratio and simplified ratio format.

5. Frequently Asked Questions (FAQ)

Q1: Why is aspect ratio important?
A: Aspect ratio affects how content is displayed on screens, prevents image distortion, and ensures proper formatting for different media types.

Q2: How do I find the aspect ratio of an image?
A: Check the image properties to find its dimensions, then divide width by height or use this calculator.

Q3: What's the difference between aspect ratio and resolution?
A: Resolution refers to the total number of pixels (e.g., 1920×1080), while aspect ratio describes the proportional relationship between width and height.

Q4: Can aspect ratio be expressed as a single number?
A: Yes, it's often expressed as a decimal (e.g., 1.78 for 16:9), but the colon format (16:9) is more commonly used.

Q5: How does aspect ratio affect video content?
A: Different aspect ratios can cause black bars (letterboxing or pillarboxing) if the content doesn't match the display's aspect ratio.
