Overview

Broadsign’s DOOH Specs Guide is designed to prevent a very practical campaign failure: creative being rejected or delayed because it does not match publisher requirements. It explains why DOOH specifications differ from web formats, gives common landscape, portrait and horizontal dimensions, covers static JPG/PNG, MP4 video and HTML5 dynamic creative, and discusses publisher approval. The guide repeatedly recommends confirming the exact media-owner specification, but it gives buyers and creative teams a strong baseline before production begins.
