Formula and methodology
Formula: Scaled width = width×scale; scaled height = height×scale; pixel count = width×height×scale²; aspect ratio = width/height.
Uniform scaling multiplies both dimensions by the same factor. Pixel count changes with the square of the scale factor, which is important for memory, bandwidth, and rendering cost.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Original width — px; minimum 1; maximum 1000000000
- Original height — px; minimum 1; maximum 1000000000
- Scale factor — ×; minimum 1.0E-6; maximum 1000
Worked example
| Input | Value |
|---|---|
| Original width | 1920 |
| Original height | 1080 |
| Scale factor | 0.5 |
The scaled resolution is 960 × 540 pixels with the same 16:9 ratio and 25% of the original pixel count.
Assumptions and limits
- Width and height are scaled uniformly with no crop or stretch.
- Fractional scaled dimensions are reported numerically; a real image pipeline must choose a rounding rule.
- The result is a geometric estimate, not a prediction of visual quality.
