Scale Resolution Formula:
From: | To: |
Resolution scaling is the process of adjusting the size of an image or display by applying a scaling factor to its original dimensions. It's commonly used in graphics design, video game development, and display settings.
The calculator uses the simple scaling formula:
Where:
Explanation: The formula linearly scales the resolution by the specified factor. A scale of 1 maintains original size, less than 1 reduces size, and greater than 1 increases size.
Details: Proper resolution scaling is essential for maintaining image quality when adapting content to different display sizes or when optimizing performance in graphics applications.
Tips: Enter the original resolution in pixels and the desired scale factor. The calculator will compute the new resolution. For width and height, calculate each dimension separately.
Q1: What's the difference between scaling up and scaling down?
A: Scaling up (factor >1) increases resolution but may cause pixelation. Scaling down (factor <1) decreases resolution and can make images appear sharper but with less detail.
Q2: How does this relate to DPI/PPI?
A: Resolution scaling changes pixel dimensions, while DPI/PPI affects how many pixels are displayed per inch. Both affect perceived image quality.
Q3: What about non-integer scale factors?
A: Non-integer factors (like 1.5x) often require interpolation, which can slightly blur the image. The calculator provides the mathematical result before any rendering adjustments.
Q4: Can I use this for both width and height?
A: Yes, but you need to calculate width and height separately unless you're using a uniform scale factor for both dimensions.
Q5: How does this affect aspect ratio?
A: Using the same scale factor for width and height maintains the original aspect ratio. Different factors will stretch or squeeze the image.
