1. What is a Pixel Ratio Resize Calculator?

Definition: This calculator determines new image dimensions while maintaining the original aspect ratio using a scale factor.

Purpose: It helps designers, photographers, and developers resize images proportionally for different display requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• New Dimension — Resized width or height (pixels)
• Old Dimension — Original width or height (pixels)
• Scale Factor — Multiplier for resizing (dimensionless)

Explanation: Both width and height are multiplied by the same scale factor to maintain the original aspect ratio.

3. Importance of Proportional Resizing

Details: Maintaining aspect ratio prevents image distortion and ensures visual consistency across different displays and platforms.

4. Using the Calculator

Tips: Enter the original width and height in pixels, and the desired scale factor (1.0 = same size, 0.5 = half size, 2.0 = double size).

5. Frequently Asked Questions (FAQ)

Q1: Why maintain aspect ratio when resizing?
A: Preserving the aspect ratio prevents images from appearing stretched or squashed, maintaining their original proportions.

Q2: What's a typical use case for this calculator?
A: Creating responsive image versions for websites, preparing images for different screen resolutions, or batch resizing photo collections.

Q3: How precise are the results?
A: Results are rounded to whole pixels since display dimensions must be integers.

Q4: Can I use this for non-image dimensions?
A: Yes, it works for any dimensional scaling where maintaining proportions is important (e.g., UI elements, video resolutions).

Q5: What if I need specific output dimensions?
A: Calculate the required scale factor by dividing your desired dimension by the original dimension.
