Bulletin vs. Poster vs. Digital Billboard: Which Format Fits Your Campaign?
Most first-time out-of-home buyers ask some version of the same question: which type of billboard should I actually run? The honest answer is that it depends on what the campaign needs to do, not which format looks the most impressive. Here's how the three most common formats actually differ.
Bulletins: reach and scale
Bulletins are the large-format boards most people picture when they hear "billboard," typically around 14 by 48 feet, often with extensions. They're built for highways and major arterial roads, where the goal is broad reach across a drive-time audience rather than a hyper-local footprint.
Because they're static, bulletins usually run for longer stretches, often a month or more, and work well for brand awareness campaigns, seasonal promotions with a few weeks of lead time, or messages that don't need to change often.
Poster panels: density and frequency
Posters are smaller street-level panels, placed more densely across a metro area. Where a handful of bulletins might cover a highway corridor, dozens of posters can blanket a neighborhood or business district. That makes posters a strong fit for local businesses, community messaging, or campaigns that need frequency within a specific radius rather than long-distance visibility.
Posters also tend to rotate on a set schedule, which keeps a saturation buy feeling current even on a tighter budget than an equivalent bulletin campaign.
Digital spectaculars: flexibility and speed
Digital billboards trade a physical print for a full-motion display, which changes what's possible on two fronts. First, creative can update without a truck roll: change your message for a weekend promotion, a weather event, or a daypart, without waiting on production and installation. Second, multiple advertisers or multiple messages from the same advertiser can rotate on one screen, which is why digital slots are often sold in shorter increments than static bulletins.
The tradeoff is usually cost per slot and availability. Digital inventory in dense corridors is in high demand, and because your message shares screen time with rotating content, a single viewer sees your creative less often than they would a static board in the same location.
So which one should you run?
- Choose a bulletin if you need broad reach, a long campaign window, and a message that doesn't need to change.
- Choose posters if you need dense, local frequency on a tighter budget.
- Choose digital if you need creative flexibility, shorter commitments, or want to react to timing, weather, or inventory in real time.
Most multi-market campaigns end up using a mix rather than a single format. If you're not sure where to start, walk through the formats in more detail or tell us your goal and we'll recommend a starting mix.
