1. What is Aspect Ratio Scaling?

Aspect ratio scaling calculates new dimensions for an image or object while maintaining its original proportions. This prevents distortion when resizing images or videos.

2. How Does the Calculator Work?

The calculator uses the aspect ratio scaling formula:

Where:

• \( \text{original\_width} \) — Original width in pixels
• \( \text{original\_height} \) — Original height in pixels
• \( \text{new\_height} \) — Desired new height in pixels
• \( \text{new\_width} \) — Calculated width to maintain aspect ratio

Explanation: The formula calculates the proportional width needed when you change the height, ensuring the image doesn't appear stretched or squashed.

3. Importance of Maintaining Aspect Ratio

Details: Maintaining aspect ratio is crucial for professional image resizing, responsive web design, video production, and any application where visual proportions must be preserved.

4. Using the Calculator

Tips: Enter original dimensions in pixels, then enter your desired new height. The calculator will determine the proportional width needed to maintain the original aspect ratio.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate new height if I know the desired width?
A: Yes, use the formula: new_height = original_height × (new_width / original_width)

Q2: What if my image has decimal pixel dimensions?
A: Pixel dimensions are typically whole numbers, but the calculation may produce decimals which you can round to the nearest integer.

Q3: Does this work for all aspect ratios?
A: Yes, the formula works for any aspect ratio (4:3, 16:9, 1:1, etc.) as it maintains the original proportion.

Q4: How does this relate to DPI/PPI?
A: This calculates pixel dimensions only. For print resolution (DPI/PPI), additional calculations would be needed.

Q5: Can I use this for video resolutions?
A: Yes, the same principle applies to scaling video resolutions while maintaining aspect ratio.
