1. What is a Pixel To Ratio Calculator?

Definition: This calculator converts pixel dimensions to aspect ratios, showing both the decimal value and simplified ratio format.

Purpose: It helps designers, photographers, and videographers determine the aspect ratio of images or screens based on their pixel dimensions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Aspect ratio (dimensionless)
• \( W \) — Width in pixels
• \( H \) — Height in pixels

Explanation: The width is divided by height to get the aspect ratio, which is then simplified to its smallest whole number ratio.

3. Importance of Aspect Ratio Calculation

Details: Correct aspect ratios ensure proper image display across different devices and platforms without distortion or cropping.

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 does my ratio simplify differently than expected?
A: The calculator finds the greatest common divisor (GCD) to simplify. Some ratios like 16:9 are already simplified.

Q3: Can I use this for non-pixel dimensions?
A: Yes, the calculator works with any consistent units (inches, cm, etc.), though results are labeled in pixels.

Q4: What's the difference between decimal and simplified ratio?
A: The decimal shows the exact ratio value, while simplified shows the standard whole number ratio format.

Q5: How precise is the decimal ratio?
A: The decimal is shown to 4 decimal places, which is sufficient for most applications.
