Social Media Video Aspect Ratio & Safe Zone Simulator

Text and key visuals placed near the edges of a short-form video often get covered by the platform's own UI — captions, like buttons, usernames, and progress bars. This simulator loads your video or image directly into pixel-accurate mockups of the TikTok, Instagram Reels, and YouTube Shorts interfaces, so you can see precisely what will and won't be visible before you publish.

Toggle the dashed safe-zone guide lines on or off for each platform, and switch Instagram's overlay between light and dark themes to match how different viewers will actually see it.

Why this matters

Every platform reserves a different amount of space around the edges for its own UI. Designing your captions and key subjects to stay inside the safe zone means your content looks intentional instead of accidentally cropped by someone else's buttons.
