1. What is an Image 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 web developers maintain consistent proportions when resizing or cropping images.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( AR \) — Aspect ratio (unitless)
• \( width \) — Image width in pixels
• \( height \) — Image height in pixels

Explanation: The calculator divides width by height to get the decimal aspect ratio, then simplifies the ratio to its smallest whole number form.

3. Importance of Aspect Ratio

Details: Maintaining correct aspect ratios prevents image distortion and ensures proper display across different devices and platforms.

4. Using the Calculator

Tips: Enter the image 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 4:3 (standard), 16:9 (widescreen), 1:1 (square), 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 use aspect ratio for cropping?
A: Maintain the same width:height proportion when cropping to preserve the original composition.

Q4: What's the difference between pixel dimensions and aspect ratio?
A: Pixel dimensions are absolute measurements, while aspect ratio describes their proportional relationship.

Q5: Can I calculate aspect ratio from physical dimensions?
A: Yes, use the same formula with any consistent units (inches, cm, etc.), though this calculator uses pixels.
