1. What is Pixel Ratio Resizing?

Pixel ratio resizing calculates new dimensions for images or videos while maintaining the original aspect ratio. This prevents distortion when changing the size of visual media.

2. How Does the Calculator Work?

The calculator uses the pixel ratio formula:

\[ \text{New Height} = \text{New Width} \times \left( \frac{\text{Old Height}}{\text{Old Width}} \right) \]

Where:

New Width — Desired width in pixels
Old Height — Original height in pixels
Old Width — Original width in pixels

Explanation: The formula preserves the original aspect ratio by scaling the height proportionally to the new width.

3. Importance of Maintaining Aspect Ratio

Details: Maintaining aspect ratio prevents stretching or squishing of images/videos, ensuring they appear as intended by the original creator.

4. Using the Calculator

Tips: Enter the desired new width and the original dimensions. All values must be positive numbers (pixels).

5. Frequently Asked Questions (FAQ)

Q1: Why is maintaining aspect ratio important?
A: It prevents distortion of images/videos and maintains the intended visual proportions.

Q2: Can I calculate new width from height?
A: Yes, the formula can be rearranged: New Width = New Height × (Old Width / Old Height).

Q3: Does this work for all image/video formats?
A: Yes, the aspect ratio calculation is format-independent as long as you know the original dimensions.

Q4: What if I want to crop instead of resize?
A: Cropping changes the aspect ratio by removing parts of the image, which requires different calculations.

Q5: How precise are the calculations?
A: The calculator provides pixel-perfect results when the output dimensions are integers.
