Resizing is not the same as reframing
Changing 1920×1080 into 1080×1920 without a composition decision either stretches the artwork or crops the most important subject.

Why this exists
Solve the small production problem before it becomes an expensive one.
Music creators turning one release into wide, vertical and square campaign formats.
Black bars become part of the uploaded video
Manually adding padding prevents adaptive players such as YouTube from displaying the video naturally on different devices.
Campaign formats drift apart
When each export is guessed independently, logo scale, safe margins and focal points stop feeling like one release.
Three-step workflow
1
Enter the source dimensions
The calculator reduces them to a clean ratio and identifies a familiar platform format when one is close enough.
2
Choose the destination
Select wide, vertical, square or Canvas, then set the dimension you must preserve. The matching dimension is calculated without stretching.
3
Reposition the scene
Use the result as the new composition size. Move layers into the new safe area instead of scaling the complete frame blindly.
Practical answers
Frequently asked questions
What is the standard YouTube aspect ratio?
YouTube identifies 16:9 as its standard computer-player ratio. Common 16:9 sizes include 1920×1080, 2560×1440 and 1280×720.
Should I add black bars to a vertical video?
No. YouTube recommends uploading the native ratio without embedded padding or black bars so its player can adapt correctly.
What ratio should I use for Shorts and Reels?
A full-screen vertical composition is normally 9:16, commonly 1080×1920.
Will the calculator crop my video?
No. It calculates dimensions and explains the format change. Reframing and cropping remain creative decisions inside your editor.
