[RecruitmentAds.com builds the whole ad set from a vacancy URL →](https://recruitmentads.com/) Safe zone ## What TikTok's interface covers, and where The interface regions in this mockup, drawn to scale on a 9:16 frame. Named rather than numbered, because TikTok's zone moves. TikTok gives no number, and says why: > “The safe zone size is determined by the dimension (vertical, horizontal or square), the ad caption length and any interactive add-on usage; the longer the caption, the smaller the safe zone will be.” [TikTok Ads Manager Help Centre, Auction In-Feed Ads](https://ads.tiktok.com/help/article/tiktok-auction-in-feed-ads) · accessed 5 Aug 2026 A moving zone cannot be stated as a percentage, so TikTok hands out overlay files instead. They are downloadable from its help articles, split by dimension (vertical, horizontal, square), by ad stage, and by reading direction (left-to-right and Arabic right-to-left). TikTok does name what sits in the covered space: the nickname, the ad caption and the music caption, all in white, all bottom-left. That leads straight to its one design warning: > “Avoid using transparent or white background for the creative, as nicknames, ad captions, and music captions may not be visible, because the text color and UI icons on the TikTok app are white.” [TikTok Ads Manager Help Centre, Auction In-Feed Ads](https://ads.tiktok.com/help/article/tiktok-auction-in-feed-ads) · accessed 5 Aug 2026 In practice: the caption and CTA block takes roughly the lower quarter of the frame, the action rail runs up the right edge, and the feed navigation sits along the top. Keep faces, text and logos out of all three, and use the overlay above to check your own file. ### Measurements of this mockup So any page telling you “TikTok's safe zone is X%” did not get that from TikTok. Six TikTok-owned pages carry safe-zone guidance and not one of them states a number for video (checked 5 August 2026). ### See the six pages, and what each publishes Published specs ## TikTok In-Feed ad specs Check which table you need first. Auction and reservation In-Feed are the same placement bought two ways, and TikTok publishes different figures for each, so they are kept apart here. ### Auction In-Feed (For You) | Field | Value |

Not as a number for video. TikTok describes safe zones across its help pages and distributes downloadable overlay files, but no TikTok-owned page states a pixel or percentage value for video. The only numeric safe zone TikTok publishes anywhere is for the profile photo: 98 x 98 px, key element centred within 66 x 66 px. ### Why does TikTok's safe zone change? Because the interface around the video changes. TikTok's help centre says the safe zone depends on the dimension, the ad caption length and any interactive add-ons; the longer the caption, the smaller the safe zone. A fixed percentage cannot describe that, which is why TikTok ships overlay files instead of a figure. ### What does TikTok's interface cover? Bottom-left: the nickname, the ad caption and the music caption, all in white, which is why TikTok warns against white or transparent backgrounds. An action rail runs up the right edge and the feed navigation sits along the top. The overlay in the tool draws all of it over your own file. ### Where do I get TikTok's official safe-zone files? From TikTok's own help articles. The auction In-Feed, reservation In-Feed and TopView pages each link downloadable safe-zone files, differentiated by dimension (vertical, horizontal, square), by ad stage, and by reading direction (left-to-right and Arabic right-to-left). TikTok distributes these files instead of publishing a number. ### Does TikTok pillarbox 9:16 video? TikTok has never said. Nothing on crop, zoom or letterbox behaviour appears in its help centre, its Creative Center or its ad policy, for any aspect ratio. Meta documents exactly what it does on taller-than-9:16 screens; TikTok does not, so treat any claim either way as unsourced. ### What size should a TikTok ad be? TikTok's recommended format is vertical 9:16 at 540 x 960 px or larger. Square 1:1 (at least 640 x 640) and horizontal 16:9 (at least 960 x 540) are also accepted. Files: .mp4, .mov, .mpeg, .3gp or .avi, up to 500 MB, up to 10 minutes for auction In-Feed. Reservation buys differ: 5 to 60 seconds at a higher bitrate floor. ### Is this tool free? Yes, and it is 100% private: nothing is saved or uploaded, your file is read in the browser and never leaves your device. No account, no email, no watermark, and there is no paid tier of this tool.
