Simulating 9:16 Shorts Viewport & Overlaying Official YouTube Player UI...
Rendering 1080 × 1920 canvas, mapping 288px top header bounds, 384px caption zone, and right action buttons.
1080 × 1920 px (9:16) Official Shorts Standard
YouTube Shorts requires a vertical 9:16 aspect ratio. Over 35% of the total screen space is covered by the player's native UI icons, title overlays, and sound labels. Our tool provides a pixel-accurate visual mockup so your content stays 100% visible.
Subtitle & Caption Protection
Placing animated captions or subtitles in the bottom 20% (384 px) will result in them being covered by your channel name, avatar, and video title. Verify your subtitle placements before rendering.
Right Action Buttons Margin
The Right Action stack (Like, Comments, Share, Audio Disc) occupies 140 pixels on the right side. Our simulator maps this exact obstruction zone to prevent hidden graphics.
Feed & Channel Grid Crop Simulation
In YouTube home feeds and channel video grids, Shorts are presented with different thumbnail crops (1:1 square or 9:16 poster). Toggle between crop modes to guarantee an eye-catching thumbnail frame.
Interactive Transparency & Guide Toggles
Control layer opacity from 20% to 100%. Switch between official UI buttons, safe zone wireframe boundaries, or pure clean video viewing with instant feedback.
Zero Quota Overhead
100% compliant with YouTube API Section III.E.2. Runs zero API quota consumption using vector overlay graphics and client-side canvas renderers.
