1. What is Image Ratio Calculation?

The image ratio calculation determines the proportional relationship between an image's width and height. It ensures that when you resize an image, it doesn't appear stretched or squashed by maintaining the original aspect ratio.

2. How Does the Calculator Work?

The calculator uses the aspect ratio formula:

Where:

• \( \text{new\_width} \) — Desired width of the resized image
• \( \text{original\_height} \) — Height of the original image
• \( \text{original\_width} \) — Width of the original image

Explanation: The formula calculates the proportional height needed to maintain the original image's aspect ratio when changing its width.

3. Importance of Maintaining Aspect Ratio

Details: Maintaining aspect ratio prevents image distortion, ensures proper display across different devices, and preserves the original composition of photographs and graphics.

4. Using the Calculator

Tips: Enter the desired new width and the original image dimensions. All values must be positive numbers (pixels). The calculator will determine the proportional height.

5. Frequently Asked Questions (FAQ)

Q1: Why is aspect ratio important in image resizing?
A: Aspect ratio maintains the proper proportions of an image, preventing distortion that occurs when width and height are adjusted independently.

Q2: Can I use this for both increasing and decreasing image size?
A: Yes, the formula works for both enlarging and reducing image dimensions while maintaining proportions.

Q3: What if I know the new height but need the width?
A: You can rearrange the formula: new_width = new_height × (original_width/original_height).

Q4: Does this work for all image formats?
A: Yes, the aspect ratio calculation is format-independent and works for JPG, PNG, GIF, etc.

Q5: How precise are the calculations?
A: The calculator provides pixel-perfect results, though final display may vary slightly depending on the device's rendering.
