Social video spec sheet
Canvas sizes, lengths, audio and caption safe zones for YouTube, TikTok, Facebook, Instagram, Pinterest, Reddit, Google and connected TV video ads.
From each platform’s own ad spec pages, last reviewed between September 28 and October 18, 2026. Wavemaker checks finished videos against these same figures when it delivers to a placement.

Loudness
None of these platforms publishes a loudness target on its spec pages, so there is no number to hit for social feeds. Connected TV is the exception: publishers measure against the ATSC A/85 reference of −24 LKFS. Wavemaker measures loudness on every delivery and reports it.
