Aspect Ratio Formula:
From: | To: |
Aspect ratio is the proportional relationship between the width and height of an image, screen, or display. It is expressed as two numbers separated by a colon (e.g., 16:9) or as a decimal value.
The calculator uses the aspect ratio formula:
Where:
Explanation: The calculator provides both the decimal aspect ratio and the simplified ratio format (e.g., 16:9).
Details: Aspect ratio is crucial in photography, video production, web design, and display technology. It affects how content is displayed, cropped, and scaled across different devices and platforms.
Tips: Enter the width and height values in the same units (pixels, inches, etc.). Both values must be positive numbers greater than zero.
Q1: What are common aspect ratios?
A: Common ratios include 4:3 (traditional TV), 16:9 (HDTV), 1:1 (square), and 21:9 (ultrawide).
Q2: How do I maintain aspect ratio when resizing?
A: Multiply the original height by the desired width divided by original width, or vice versa, to maintain proportions.
Q3: What's the difference between aspect ratio and resolution?
A: Aspect ratio describes the shape (width:height proportion), while resolution describes the number of pixels (e.g., 1920×1080).
Q4: Can aspect ratio affect image quality?
A: Yes, stretching or compressing an image to fit a different aspect ratio can distort it and reduce quality.
Q5: How do I calculate aspect ratio from resolution?
A: Divide the width by the height and simplify the fraction (e.g., 1920÷1080 = 16:9).
