Resolution Scaling Calculator
Scale your image or screen resolution up or down with ease.
Why Use a Resolution Scaling Calculator?
Resolution scaling helps you adjust the size of images, videos, or screens while maintaining proportions. Whether you’re designing graphics, resizing photos for print, or setting up projector displays, scaling ensures your visuals remain sharp and proportionate.
Formula
New Width = Original Width × (Scale Factor ÷ 100)
New Height = Original Height × (Scale Factor ÷ 100)
Example Calculation
Suppose your original resolution is 1920 × 1080 and you want to scale it down to 75%:
New Width = 1920 × 0.75 = 1440 pixels
New Height = 1080 × 0.75 = 810 pixels
The scaled resolution is 1440 × 810.
Use Cases
- Gaming: Adjust resolution for better performance.
- Graphic Design: Resize images without losing proportions.
- Projectors: Match screen resolution to projector capabilities.
- Printing: Scale photos for different print sizes.
Common Scaling Values
- 200%: Double the resolution dimensions.
- 150%: Increase by half.
- 75%: Reduce to three-quarters of original size.
- 50%: Half the original size.
FAQs
Does scaling affect image quality?
Scaling down usually preserves quality. Scaling up may reduce sharpness if the original image lacks detail.
Can I change only width or height?
Yes, but that will distort the image. To keep proportions, scale both dimensions equally.
What’s the best scale for 4K to 1080p?
50% scaling reduces 3840 × 2160 (4K) to 1920 × 1080 (Full HD).
Conclusion
Our Resolution Scaling Calculator makes it easy to resize images, videos, or screens without guessing. By applying proportional scaling, you can optimize performance, ensure compatibility, and maintain visual quality.
