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.

Understand why DOOH has publisher-specific creative approval
Recognize common screen orientations and dimensions
Prepare static and video assets in common formats

How to Use This Resource

DOOH Specs Guide for Media Buyers & Planners is best used as a technical guide rather than as a live rate card. Treat the examples and frameworks as a way to ask better questions before a proposal, then verify inventory, pricing, dates and specifications with the seller or platform.

The strongest planning value is in Creative Specs, DOOH, Production, and Trafficking. Those topics connect directly to how outdoor media is bought: the screen or panel still has to match the audience journey, the creative has to be readable in context, and any measurement claim should be tied to a stated methodology.

Because this resource is provided by Broadsign, read it with the provider context in mind. Vendor education can be useful, but it should be balanced against independent market checks and competing quote paths.
