YouTube bumper ad size

A YouTube bumper ad is a non-skippable video of 6 seconds or less on most of Google's pages; its video ad formats page says between 5 and 6. Google's video ad specs page recommends 1920 × 1080 for horizontal video, 1280 × 720 minimum, up to 256 GB, with an optional 300 × 60 companion banner on desktop. Google's reference overlay for horizontal video applies.

Google's reference overlay for horizontal video ads, which bumpers share. Google says overlays, calls to action and buttons "may appear in different places depending on the format, campaign type, and screen" — a reference, not a guarantee. Drawn at 1920 × 1080. The shaded bands are 3.5% of the height at the top, 35.8% at the bottom, 2% of the width on the left and 8.4% on the right — 38, 387, 38 and 162px at this canvas size only. The top-left corner is shaded too, 25.8% of the width by 16.9% of the height — 496 × 183px, and the top-right corner 24.8% by 12.3% — 476 × 133px.
