Aspect Ratio Formula:
From: | To: |
Definition: This calculator determines the aspect ratio of an image or display based on its pixel resolution.
Purpose: It helps designers, photographers, and video editors understand the proportional relationship between width and height of digital images or screens.
The calculator uses the formula:
Where:
Explanation: The aspect ratio is calculated by dividing the width by the height, and then optionally simplified to a common ratio format (e.g., 16:9).
Details: Proper aspect ratio ensures correct image display without distortion, maintains consistency across devices, and is crucial for video production and responsive web design.
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 (HDTV), 4:3 (traditional TV), 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). Our calculator does this automatically.
Q3: Does pixel count affect aspect ratio?
A: No, aspect ratio depends only on the proportional relationship between width and height, not the absolute pixel count.
Q4: What's the difference between display resolution and aspect ratio?
A: Resolution is the total pixel count (e.g., 1920×1080), while aspect ratio is the width:height relationship (e.g., 16:9).
Q5: Why is aspect ratio important in photography?
A: It affects composition, printing, and how images appear on different devices or when cropped.
