Video Aspect Ratio Calculator

16:9 (1920 × 1080 px) is the standard for YouTube music videos, official audio, and lyric videos. This is the native widescreen format YouTube was designed for. Using a different ratio results in black bars (letterboxing or pillarboxing) on most screens.

9:16 at 1080 × 1920 px is the recommended size for Instagram Reels. This fills the full screen on mobile. Keep important content — text, faces, and logos — in the center 80% of the frame to avoid being covered by Instagram's UI elements at the top and bottom.

Yes — all three platforms use the 9:16 aspect ratio at 1080 × 1920 px. However, each platform places UI overlays in slightly different positions, so check the safe zones for each before exporting. TikTok overlays the bottom 15% for controls; Instagram overlays the bottom 20% for captions.

The safe zone is the area of your video frame that will definitely be visible and not covered by platform UI elements like captions, buttons, or handles. For most vertical platforms (Reels, TikTok, Shorts), keep your important content — text, logos, faces — between 15% from the top and 20–35% from the bottom of the frame.

Aspect ratio is the proportional relationship between a video's width and height. It is expressed as width:height — for example, 16:9 means the video is 16 units wide for every 9 units tall. The same aspect ratio can be rendered at many different resolutions: 1920×1080 and 1280×720 are both 16:9.

Export at 1920 × 1080 px (1080p) as a minimum. For music videos and official content, 3840 × 2160 px (4K) is recommended if your original footage supports it. YouTube compresses uploads, but higher-resolution source files result in better-looking compressed output.
