1. What is an Aspect Ratio Calculator?

Definition: This calculator determines the aspect ratio of an image based on its width and height in pixels.

Purpose: It helps photographers, designers, and content creators maintain consistent proportions when resizing images.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Aspect ratio (dimensionless)
• \( W \) — Image width (pixels)
• \( H \) — Image height (pixels)

Explanation: The width is divided by height to get the decimal ratio, then simplified to the smallest whole numbers.

3. Importance of Aspect Ratio

Details: Maintaining proper aspect ratios ensures images display correctly without distortion across different devices and platforms.

4. Using the Calculator

Tips: Enter the image width and height in pixels. Both values must be > 0. The calculator provides both decimal and simplified ratio formats.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 1:1 (square), 4:3 (standard), 16:9 (widescreen), and 3:2 (35mm film).

Q2: Why does my image look stretched?
A: This happens when an image is resized without maintaining its original aspect ratio.

Q3: How do I maintain aspect ratio when resizing?
A: Either lock the aspect ratio in your editing software or calculate the new dimensions using this ratio.

Q4: What's the difference between decimal and simplified ratio?
A: Decimal is precise (e.g., 1.7778), while simplified is whole numbers (e.g., 16:9) - both represent the same proportion.

Q5: Can I calculate height from width and ratio?
A: Yes, height = width / ratio. We may add this feature in future updates.
