Social media safe zone checker

Nobody publishes the numbers any more. Meta took its pixel guidance down and replaced it with a yellow overlay inside Ads Manager, and the only figure left on its live safe zone page is that Reels ads with disclaimers should keep the bottom 40% clear. TikTok gives you ZIP files of overlay images rather than a table. Google publishes nothing for Shorts.

The numbers still circulating come from a Meta ads guide that now returns a login wall, and they contradict themselves. That guide said the top 14% or 250px, but 14% of a 1920px canvas is 269px. It said the bottom 20% or 340px for Stories, and 20% of 1920 is 384px. Those two sentences cannot both be true, which tells you what kind of precision was on offer even when the page was live.

TikTok is the most honest about it: its help page says the safe zone depends on the dimensions, the caption length and any extra formats in use, that a longer caption means a smaller safe zone, and that the overlay may not cover every device. A fixed PNG cannot express any of that.
