Aspect Ratio Formula:
From: | To: |
Definition: This calculator determines the aspect ratio of an image or screen based on its width and height in pixels.
Purpose: It helps designers, photographers, and videographers understand and maintain proper aspect ratios for their projects.
The calculator uses the formula:
Where:
Explanation: The calculator divides width by height to get the decimal aspect ratio, then simplifies the ratio to its lowest terms.
Details: Correct aspect ratios ensure proper display across different devices, prevent image distortion, and maintain professional standards in media production.
Tips: Enter the width and height in pixels (must be positive integers). The calculator provides both decimal and simplified ratio formats.
Q1: What are common aspect ratios?
A: Common ratios include 16:9 (HD), 4:3 (SD), 1:1 (square), and 21:9 (ultrawide).
Q2: Why does my ratio simplify to 16:9?
A: If your width is 1920 and height is 1080, dividing by GCD (120) gives 16:9 - the standard HD ratio.
Q3: How precise is the decimal aspect ratio?
A: The decimal is calculated to 4 decimal places for most applications, though some professional uses may require more precision.
Q4: Can I use this for non-pixel dimensions?
A: Yes, the calculator works with any consistent units (inches, cm, etc.), though it's optimized for pixel inputs.
Q5: What if I get an aspect ratio like 683:384?
A: This is a valid simplified ratio (e.g., 1366×768 display). Some ratios don't simplify to common numbers.
