1. What is a Pixel to Ratio Calculator?

Definition: This calculator determines the aspect ratio from pixel dimensions and provides both decimal and simplified ratio formats.

Purpose: It helps designers, photographers, and video editors understand the proportions of images and screens.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Ratio — Aspect ratio (unitless)
• Width_pixels — Horizontal dimension in pixels
• Height_pixels — Vertical dimension in pixels

Explanation: The calculator also simplifies the ratio by dividing both dimensions by their greatest common divisor.

3. Importance of Aspect Ratio Calculation

Details: Correct aspect ratios ensure proper image display, prevent distortion, and maintain consistency 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: Why is simplified ratio important?
A: Simplified ratios are easier to understand and communicate (e.g., "16:9" vs. "1.7778:1").

Q3: Can I calculate ratio from physical dimensions?
A: Yes, as long as width and height are in the same units (inches, cm, etc.).

Q4: How does this relate to resolution?
A: Resolution is the pixel count (e.g., 1920×1080), while aspect ratio describes their proportion (16:9).

Q5: What if my image is portrait orientation?
A: The calculator works the same - it will show ratios like 9:16 for vertical images.
