In the United States, standard billboard sizes come in three primary dimensions:

• 14 feet high by 48 feet wide

Many 30-sheet locations now also support digital displays, enabling rotating creative, real-time updates, and dynamic content that adapts to time-of-day or audience behavior.

• 6 feet high by 12 feet wide

Did you know? The term “junior poster” originally referred to a 6-sheet billboard—the smallest standard format—measuring 4 feet 4 inches by 9 feet 10 inches. Other now-rare legacy formats included 3-sheets (3×6 feet, often placed outside shops) and 24-sheets, which were once the most common billboard size in the U.S.

What Is an 8-Sheet Billboard?

Often called **junior posters**, 8-sheet billboards are a compact, cost-effective outdoor advertising option that excels in walkable, urban environments. You’ll typically spot them near:
Busy intersections

Restaurants, bars, and retail corridors

Sidewalls or stand-alone street-level frames

Though smaller than bulletins or spectaculars, 8-sheets punch above their weight when it comes to street-level impact. They’re designed to grab attention from both pedestrians and drivers, especially in areas where foot traffic is dense and messaging needs to land quickly.

8-sheets are often used to:

Promote concerts, film releases, or local events

Advertise retail sales or product launches

Reinforce brand awareness in key zip codes

These billboards are typically rented on a monthly basis, and many locations now support digital 8-sheet formats for rotating or time-sensitive creative.

What Are the Standard Sizes for Mobile Billboards?

**Mobile billboards** come in various sizes, depending on the truck or trailer used to carry them. These billboards are mounted on flatbeds or box trucks and driven through high-traffic areas to maximize reach and visibility. Common dimensions for mobile billboard displays include:

• 6’4” high x 11’ wide: A compact option perfect for navigating tighter urban streets and congested city centers.
• 10’ high x 22’ wide: A larger format ideal for high-impact exposure along busy highways and major intersections.

Mobile billboard advertising offers brands a dynamic, flexible way to engage audiences where they live, work, and play. These billboards on wheels can be scheduled to reach multiple neighborhoods or events in a single day—making them highly adaptable for time-sensitive promotions or geographic targeting.

Most modern mobile billboards feature digital screens, which allow for easy creative updates, animated visuals, and even interactive messaging such as QR codes. Their real-time flexibility and geographic precision make them an ideal supplement to any outdoor advertising campaign.

Whether you’re launching a new product, promoting a tour, or running a local awareness campaign, mobile billboards deliver visibility where it matters most—right in front of your target audience.

Factors to Consider When Choosing the Right Billboard Size

Selecting the ideal **billboard size** for your campaign requires balancing strategy, creativity, and budget. The right format can significantly influence your campaign’s visibility and ROI. Here are key considerations to help guide your decision:

• Budget: Larger billboards offer greater exposure but come with higher rental and production costs. Smaller formats can still be highly effective in the right locations.
• Creative Execution: The size and shape of your billboard affect how much content you can include and how it will appear to viewers from various distances.
• Lighting: Billboards with backlighting or digital displays can boost visibility at night or in low-light conditions.
• Visibility: The physical placement and height of a billboard will determine sightlines—critical for catching attention from far away or in dense traffic.
• Time Constraints: Short-term campaigns may benefit from digital billboards that allow real-time updates, while long-term efforts might favor static installations.
• Target Audience: Choose a format aligned with who you’re trying to reach—whether that’s highway drivers, city commuters, or foot traffic in urban zones.
• Permanence: Depending on your strategy, you might want a **rotary billboard** (which changes locations) or a permanent fixture in a high-value area.
