YouTube ad sizes & safe zones
All 20 YouTube ad formats (5 image, 15 video), grouped by placement category — the same specs the resizer exports.
Safe-zone values are pixels (top / bottom / left / right) at the format's native recommended resolution — keep text, logos, and CTAs out of those margins so platform UI doesn't cover them. Formats without a value have no platform-documented safe zone.
