And bigger doesn't always mean better. A3s slip into busy spaces where people stop and notice, while large-format posters dominate key city sites.
That’s why at Phantom, we offer access to over 6,500 outdoor spaces across the country - from hidden laneways to iconic city walls. Big or small, every format brings its own kind of impact, turning your message into a visible, memorable part of the urban landscape.
Where you place your poster is just as important as its design. The location and audience determine which poster size works best, ensuring your message reaches the right people effectively.
Consider audience distance, small posters perform well up close, while larger formats reach people further away.
Size: 297mm x 420mm
Small but sharp, A3 posters work well in intimate spots, laneways, shopfronts, and community boards where people stop and look up close.
They’re a natural fit for local gigs, cultural events, or grassroots campaigns that thrive in smaller spaces. Perfect for community-focused messaging in environments where audiences are already paying attention.
Size: 594mm x 841mm
With more room for design, A1 posters stand out in mid-traffic locations across the network. Think side streets, neighbourhood centres, and retail strips where scale matters but intimacy is still important.
They strike a balance between size and detail, making them ideal for walkways, venue entrances, or areas where passers-by might pause and take notice.
Size: 900mm x 1300mm
Large and eye-catching, Max A0 posters bring campaigns to life in busier urban backdrops. Positioned on well-trafficked streets and building walls, they give brands the visibility needed to break through the noise.
Great for street-level impact, they put your message directly in front of high-footfall audiences when timing and placement matter most.
Size: 600mm x 2500mm
Compact but highly effective, Bollard posters place your message at eye level along pedestrian routes.
Perfect for guiding attention or supporting a wider campaign, they create targeted engagement in areas with consistent foot traffic.
Size: 1800mm x 2600mm
These oversized formats dominate prominent Phantom sites across major cities.
Perfect for brand campaigns aiming for more than just local reach, they demand attention in high-traffic areas where thousands pass by daily.
Their sheer scale ensures your message stands tall and doesn’t get lost in the crowd.
Size: Custom large-format (varies by site)
The biggest of the lot. Mega posters turn whole building walls into statement pieces, anchoring your brand within the city’s visual culture.
They’re impossible to miss and turn your campaign into a landmark - becoming part of the streetscape itself.
Once you know the standard poster sizes, the next step is working out which one actually fits your purpose.
The right poster size should support your campaign’s goal and connect with your audience where they are. Here’s how to align size with purpose:
These posters are designed to dominate high-traffic streets and key building walls. Strategically placed across the network, they make your campaign unavoidable, turning city spaces into your brand’s canvas
Medium-sized posters offer the best of both worlds: bold enough to stand out on a busy street, but still detailed enough to carry more information. They’re often placed on well-walked routes, outside popular venues, or in clusters along walls. These placements mean people have a moment to actually read and engage, making this size a strong choice for campaigns that need visibility without losing nuance.
Smaller posters like A3 work well on bulletin boards, shop windows, or community spaces. They’re cost-effective, easy to distribute, and great for campaigns that rely on multiple posters to spread the word.
For Max A0, Super, or Mega posters, focus on bold visuals and minimal text. Your main message should be instantly readable. High-quality images and contrasting colours make your poster stand out in high-traffic areas.
Medium posters can carry a bit more detail. Include a short tagline or extra information, but keep the layout clean. Use ample space around your visuals and text to make sure the message is easy to follow.
Small posters shine in spots where people can stop and read, like community boards, shop windows, or local events. This is a great way to share detailed information without overwhelming your audience.
Your main point should grab attention first. Use text hierarchy and visuals strategically. Add interactive elements like QR codes or short links to connect with digital campaigns, giving your audience a clear next step.
Match colours, fonts, and tone with other marketing campaigns. Consistent design strengthens brand awareness and makes your messaging feel cohesive across multiple posters and formats.
