1. What is Screen Resolution Scale?

The screen resolution scale is the ratio between a new resolution and an old resolution. It helps determine how much an image or display needs to be scaled when changing resolutions.

2. How Does the Calculator Work?

The calculator uses the resolution scale formula:

Where:

• New Resolution — The target resolution (width or height)
• Old Resolution — The original resolution (width or height)

Explanation: The scale is calculated separately for width and height dimensions to account for possible non-uniform scaling.

3. Importance of Resolution Scaling

Details: Proper scaling is crucial when adapting content for different display sizes, maintaining aspect ratios, and ensuring visual consistency across devices.

4. Using the Calculator

Tips: Enter both old and new resolutions in pixels. All values must be positive integers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a scale of 1 mean?
A: A scale of 1 means the new resolution is identical to the old resolution (no scaling needed).

Q2: What if width and height scales are different?
A: Different width and height scales indicate non-uniform scaling, which may distort the aspect ratio of the content.

Q3: How is this useful in web design?
A: Helps designers create responsive layouts that adapt to different screen sizes while maintaining proportions.

Q4: Can I use this for image resizing?
A: Yes, this calculation helps determine the scaling factor needed when resizing images to new dimensions.

Q5: What about DPI/PPI scaling?
A: This calculator deals with pixel dimensions only. For DPI/PPI scaling, additional calculations would be needed.
