About This Free Online Resolution Scale Calculator
Our free resolution scale calculator works out new pixel dimensions when you enlarge or shrink an image, video, or canvas by a factor, while keeping the original aspect ratio intact. Enter your starting width and height and a scale factor, and the tool instantly returns the resized dimensions, so a 1920x1080 frame scaled by 1.5 becomes 2880x1620 without distortion. It is useful for designers exporting assets at multiple sizes, game developers planning render resolutions, video editors upscaling or downscaling footage, and anyone preparing graphics for different screens. Because it preserves proportions, you avoid the stretching or squashing that comes from guessing dimensions by hand. The calculation happens entirely in your browser and updates as you type, with instant results, no signup, and nothing uploaded.

Frequently Asked Questions About Resolution Scale Calculator
What is resolution scaling?
Resolution scaling is the process of altering width and height pixels by a constant multiplier. This is commonly used in gaming (render scale), video encoding, and image processing to reduce memory use or improve rendering speed.
How is megapixels calculated?
Megapixels is calculated by multiplying width by height and dividing the result by one million.
Why Choose the Resolution Scale Calculator?
Converting data should be quick and lossless. The Resolution Scale Calculator transforms your input the instant you paste it, handles edge cases cleanly, and does all the work in your browser — so there is no upload, no waiting, and no copy of your data on a server somewhere.
