DOOH Screen Types and Ad Formats

DOOH ad formats and screen types vary by venue, and each venue brings a different audience behavior, a different dwell time, and therefore a different measurement opportunity. This article walks through the main venue types and ad formats you will encounter in digital out-of-home advertising, explaining why a given format makes sense in a given environment.

Where do DOOH screens live?

The value of a DOOH screen comes less from its technical specs than from the context of the venue it sits in. The same 55-inch display might be passed in seconds in a metro corridor, yet become a surface looked at for minutes in an elevator or at an EV charging point. If you have not yet grounded the basics of the medium, the guide to what DOOH is clarifies that context.

Roadside and billboard screens

Large-format LED screens along streets and highways are the most visible face of DOOH. They offer high reach, but because the audience is usually in motion, contact time is short. For that reason, roadside screens demand a short message, strong visuals, and quick readability. They are ideal for brand-awareness campaigns.

Transit screens

This group includes metro stations, bus shelters, rail and tram platforms, and in-vehicle screens. The defining advantage of transit is waiting time: a passenger waiting for a metro may look at the same screen repeatedly and for a comparatively long time. This allows for longer, more informative content and, in certain cases, interactive formats.

Mall and retail screens

Wayfinding screens in shopping-center corridors and in-store signage offer the context closest to the purchase decision. The audience is already in a shopping mindset; when the right product is shown at the right moment, conversion potential is high. The rise of retail media networks is making these venues increasingly valuable.

Airport screens

Airports are a premium environment reaching a high-income audience with long waiting times. Their appeal to international brands stems from both the audience profile and the extended contact times created in check-in, security, and gate areas.

EV charging and forecourt screens

Electric-vehicle charging points and fuel forecourts are a new generation of DOOH environment. The driver waits at the same spot for minutes while the vehicle charges or fuels, creating a comparatively high and focused attention window. This high dwell sets the stage for both longer content and more meaningful measurement.

What are the DOOH ad formats?

Just as venue matters, so does the form of the content. The main formats are:

• Full-motion video: Animated or live-footage video that creates strong impact even without sound. It is the most effective format for capturing attention, but it requires a context where the audience will look long enough.
• Static rotation: A format where the fixed images of several brands rotate in sequence, usually in slots of a few seconds; common in short-contact environments such as roadside.
• Interactive: Formats where the audience can respond via touchscreen, QR code, or sensors. These make sense in long-wait environments (airports, malls).
• Contextual/dynamic content: Creative that changes based on time, weather, or detected audience. This capability is enabled by dynamic creative optimization (DCO).

How do venue, format, and dwell time relate?

The most frequently overlooked relationship in DOOH planning is the link between venue type and dwell time. Dwell time determines not only the format but also how meaningful the measurement can be. On a very short-contact screen, attention measurement gives a weak signal, whereas in a high-dwell environment, person counting, dwell time, and head-pose attention become far more reliable.

Venue type	Suitable format	Typical dwell (approximate)	Measurement suitability
Roadside / billboard	Static rotation, short video	Very short (1-3 s)	Low-medium
Transit (shelter/station)	Video, interactive	Medium-long (15-60 s)	Medium-high
Mall corridor	Video, static rotation	Short-medium (3-10 s)	Medium
In-store retail	Contextual/dynamic	Variable	Medium-high
Airport	Video, interactive	Long (minutes)	High
EV charging / forecourt	Video, dynamic	High (minutes)	High

The durations in this table are approximate values that shift with the environment and traffic conditions; exact figures depend on each screen’s location. Even so, the general rule is clear: as waiting time grows, both richer formats and more reliable measurement become possible.

Why does venue choice matter for measurement?

In high-dwell environments, camera-based computer vision can more robustly measure the number of people facing a screen and their dwell time. Privacy by design is critical here: face detection is used rather than face recognition, no identity is produced, and only anonymous, aggregate metadata is reported. This makes venue choice not just a reach decision but also a measurement-quality decision. The relationship between this measurement and how static OOH estimates its audience is explored further in OOH vs DOOH key differences.

Summary

DOOH screen types span a broad spectrum, from roadside to airport and from mall to EV-charging point, and each venue brings its own dwell time. When the format is chosen to fit that time, the message becomes more effective and the measurement becomes more meaningful. When starting with DOOH, the right venue-and-format match is the first step in determining the return a brand gets on its investment; the brand’s guide to DOOH advertising can offer further guidance here.
