Short-form video guides
Safe zones, sizes, specs, PNG templates, and a 9:16 converter for TikTok, Instagram Reels, YouTube Shorts, Facebook Reels, and X. Each page runs the same in-browser checker. Nothing is uploaded.
Safe zones
Margins the player UI covers on a 1080×1920 frame.
TikTok safe zone checker
Check a TikTok before you post. Official in-feed margins are 240 / 660 / 120 / 120 on a 1080×1920 frame, plus the right-hand action column. Measured organic numbers are smaller and labeled as such.
Instagram Reels safe zone
Instagram's Reels ads guide keeps 14% clear at the top, 35% at the bottom, and 6% on each side. That is 269 / 672 / 65 / 65 on a 1080×1920 frame.
YouTube Shorts safe zone
Google's vertical ad safe zone is 288 top, 672 bottom, 48 left, and 192 right on 1080×1920. Other checkers publish 380 px and disagree. Both modes are on the page.
Facebook Reels safe zone
Facebook has no separate confirmed safe zone. ClipLint draws the Meta Reels ads guide (269 / 672 / 65 / 65) and labels it as an assumption shared with Instagram.
Reels safe zone for Instagram and Facebook
One Reels safe zone, two apps. 14% top, 35% bottom, 6% sides on 1080×1920, and the length rules that actually differ between Instagram and Facebook.
