Digital Billboard Screen Sizes Explained

Digital billboards come in three main sizes – small, medium, and large – and each serves a unique purpose based on location and viewing distance.

• Small (4’×8′ to 6’×12′): Best for urban areas with close viewers. Viewing range: 25–100 feet.
• Medium (10’×20′ to 10’×36′): Ideal for suburban roads or moderate-speed traffic. Viewing range: 100–500 feet.
• Large (14’×48′ to 20’×60′): Perfect for highways and long-distance visibility. Viewing range: 500–1,000 feet.

Key design tips:

• Use large, bold fonts (1-inch text height per 1 foot of viewing distance).
• Stick to 2–3 high-contrast colors for better readability.
• Keep messages short: 7–10 words for large billboards, 3–5 for small ones.

Understanding billboard size, resolution, and placement ensures your ad grabs attention and stays effective at any distance.

Digital Billboard Size Standards

In the U.S., digital billboard standards are designed to ensure maximum visibility, no matter the environment.

Standard U.S. Billboard Sizes

Digital billboards generally fall into three main size categories:

The 14′ × 48′ billboard is a popular choice for highways. Its expansive size ensures that drivers can clearly see messages from a distance, even at high speeds.

For more adaptable options, medium formats like 10′ × 36′ fit a variety of settings. Highways might use slightly larger versions, like 10′ × 40′, while suburban areas often prefer smaller ones, such as 10′ × 30′, to blend better with local surroundings.

Size Differences by Location

Billboard dimensions often depend on where they’re placed and the type of audience they’re targeting:

• Urban areas: Smaller displays, like 6′ × 12′ or 8′ × 24′, are ideal for engaging people at closer distances.
• Highways: Larger formats, such as 14′ × 48′ or 10′ × 40′, cater to fast-moving traffic and ensure visibility at greater distances.
• Suburban settings: Medium sizes, like 10′ × 30′, strike a balance between visibility and fitting into the local landscape.

These size variations help ensure that digital billboards are effective in different environments.

Screen Technical Details

Resolution and Pixel Density

Digital billboards rely on specific pixel matrices to ensure clear and sharp visuals, which are crucial for effective advertising. The resolution of a screen directly affects how crisp the text and graphics appear. For example, a standard 14′ × 48′ billboard typically uses a pixel matrix of 920 × 260, while a 12′ × 24′ display operates at 1,350 × 650 pixels. Most digital billboards maintain a resolution of 100 DPI (dots per inch), striking a good balance between image clarity and manageable file sizes. This ensures that both text and graphics are easy to read and visually appealing.

Here’s a quick reference table that pairs billboard sizes with their corresponding pixel specifications:

Understanding these technical details is essential when considering how aspect ratios and file formats influence the overall display performance.

Screen Ratios and File Specs

Digital billboards are designed with specific aspect ratios that correspond to their physical dimensions. These ratios help determine how content will appear on the screen. Common aspect ratios include:

• Landscape ratio (approximately 1:3.4) for 14′ × 48′ billboards.
• Wide format (1:2) for 12′ × 24′ billboards.
• Square format (1:1) for 10′ × 10′ billboards.

When submitting artwork for these screens, use JPG or PNG files in RGB mode. To ensure text is legible from a distance, it should be at least 12 inches tall, with a preference for sizes between 2 to 3 feet. Avoid including intricate details or QR codes, as these elements are often too small to be effective from standard viewing distances. Instead, focus on bold, high-contrast designs that can grab attention and remain impactful, even from far away.

Screen Size and Ad Performance

Viewing Distance Guidelines

The size of a billboard directly impacts its visibility range. Larger formats are ideal for long-distance viewing, while smaller screens are better suited for close-up audiences. Here’s a quick overview of recommended viewing distances:

These distances help ensure that viewers – whether drivers or pedestrians – have enough time to notice and process the advertisement.

Size-Based Design Rules

To make your ads stand out, design elements should align with the billboard’s size and recommended viewing distance. Here’s how to tailor your content for maximum clarity and impact:

For 14′ × 48′ Billboards (Large):

• Headlines should be 24–30 inches tall (around 400–500 pixels).
• Supporting text should be at least 18 inches tall (300 pixels).
• Keep the message concise with 7–10 words maximum.

For 10′ × 30′ Billboards (Medium):

• Headlines should be a minimum of 18 inches tall (300 pixels).
• Secondary text should measure at least 14 inches tall (230 pixels).
• Limit the content to 5–7 words.

For 8′ × 16′ Billboards (Small):

• Headlines should not be smaller than 14 inches tall (230 pixels).
• Stick to 3–5 words for quick readability.

Using bold fonts ensures better readability from a distance. When it comes to color, the contrast should match the billboard size:

• Large formats: Use 3–4 colors with moderate contrast.
• Medium formats: Stick to 2–3 colors with high contrast.
• Small formats: Also use 2–3 colors but prioritize high contrast for better visibility.

Finally, balance visuals and text based on billboard size. For large displays, dedicate 60–70% of the space to visuals, while smaller billboards should allocate 40–50%. Place key messages slightly toward the center-right, as this is where viewers’ attention naturally gravitates.

Picking the Best Screen Size

Screen Size Selection Criteria

When choosing the right billboard size, several factors come into play, all of which influence how effectively your ad reaches its audience. Consider the placement, traffic speed, and viewing distances to determine the most suitable dimensions for your campaign.
