What are 48-sheets?
The 48-sheet billboard is the most popular billboard size amongst advertisers in the UK. This traditional billboard offers businesses excellent visibility and brand exposure at an affordable cost, as well as a large advertising canvas to place impactful messaging upon.
This billboard format has the mixed benefit of impact and location, and today there are many possibilities to really get creative including 3D builds! Spread across the entire nation, these can be bought in bulk or in single units fitting the marketing needs of all brands.
Two examples of a Paper 48-sheet Billboard.
Why is it called a 48-sheet?
The term “48-sheet” comes from the traditional methods of printing and posting. Traditionally, the posters were printed on large individual sheets of paper, and 48 sheets were used to create a billboard.
The dimensions of the advertising poster measure 20 feet x 10 feet. The posters, when printed, come in 12 sections of 4 sheets, resulting in a total area of 48 sheets of paper. Even though the advertising space has evolved to include digital formats, this standard size and term has been established as a uniform and recognisable space for out-of-home advertisers.
What is the size of a 48-sheet Billboard?
Although not the largest billboard within the out-of-home advertising space, 48 sheets are still large enough to make a lasting impression. For a sense of the upper end of outdoor scale, see our guide to Europe's biggest billboards — from Piccadilly Lights in London to landmark screens across the continent. And at 20 ft x 10 ft, there is ample room for advertisers to capture the attention of passersby.
At a landscape orientation, these billboards approximately measure:
20 ft width x 10 ft height
240” width x 120” height
6m width x 3m height
609 cm width x 304 cm height
Where are 48-sheets used?
You will typically find the 48-sheet billboard just about anywhere that experiences high traffic, such as busy roadsides, town centres and transport hubs. This billboard placement paired with the large advertising canvas guarantees maximum visibility to a large and diverse audience.
Common 48-sheet locations include:
Major arterial roads and roundabouts on the approach to cities and towns
Retail parks and supermarket forecourts, where shoppers are in a purchase mindset
High streets and pedestrianised areas in regional town centres
Transport hubs including rail stations and bus interchanges
Near schools, leisure centres and other destinations with consistent footfall
The positioning at eye level is an important factor. Unlike overhead formats, 48-sheets sit within the natural sightline of both drivers and pedestrians, creating consistent visual contact throughout the day.
Creative Guidelines for 48-Sheet Advertising
The 48-sheet is a glance medium. Drivers and pedestrians have between five and ten seconds to absorb your message before passing by. Creative that works on a 48-sheet follows a clear set of principles.
Keep your copy to a maximum of seven to nine words. Any more and the message becomes difficult to absorb in motion. The strongest 48-sheet campaigns use a single bold image, a brief headline, and a brand logo with nothing else competing for space. Contact details or URLs should be large enough to read at speed, but secondary to the primary message.
Typography must be bold and high-contrast. Dark text on a light background, or light text on a dark background, reads fastest at distance. Avoid script fonts and thin typefaces. The creative must communicate at 50 metres, not just up close.
Colour contrast is a key driver of attention. High-contrast combinations, such as black on yellow or white on deep blue, generate stronger recall than monochrome or pastel palettes. A passer-by's eye is drawn to contrast before it reads content.

48-Sheet billboard Costs
The 48-sheet is a cost-effective choice for businesses that want maximum impact but have limited budgets. To understand the true value of your investment, it's essential to know how to measure billboard advertising effectiveness alongside your campaign spend.
The cost of a 48-sheet billboard can start from as little as £250 for a 2-week campaign. However, like any billboard advertising, there are a number of factors that can affect the cost, such as:
Location of Billboard
Billboards in high-traffic areas such as city centres may cost more than those in less busy areas. Placing your advertisement in a high-traffic area typically results in more visibility and exposure, you can therefore expect to be paying more for these locations.
Material and Artwork Costs
Whether it’s paper, vinyl or 3D images, the choice of materials and artwork affects the initial and ongoing costs of a billboard advertisement. Some advertisers will include the cost of artwork, design and production in their quotes whereas others will add these on top. It’s best to confirm these beforehand to avoid unexpected expenses.
Campaign Duration
The campaign duration refers to the length of time in which your billboard will be displayed. Billboards are typically booked on a 2-week cycle but there are often discounts for longer-term bookings, which can be a cost-effective choice for advertisers looking for long-term impact.
Type of Billboard
The type of billboard can determine the cost of the campaign. There are two common types of billboards: traditional and digital. Digital billboards tend to be less affordable than traditional billboards because they are costly to set up and maintain.
For a full breakdown of pricing across all billboard formats and locations, see the detailed guide to billboard advertising costs.
Traditional Vs Digital Billboards
It’s important to understand the different types of billboards to get the most out of your billboard advertising campaign. Traditional billboards offer exclusivity to brands and are typically more affordable than digital billboards. Digital billboards share advertising space with a minimum of 5 other advertisers and only provide 10 seconds of display time for each minute, meaning they have less visibility and less impact compared to traditional billboards.
However, digital billboards allow for dynamic content and remote control, meaning if you need to make an update at any point during the campaign, you can do so without the associated costs of being there in person, physical materials, transportation and installation.
With traditional 48-sheet billboards, you can expect to pay £250 per 2-week booking with the benefit of exclusivity over advertising space. Digital 48-sheet billboards can set you back anywhere between £1,500-£3,000 for a 2-week slot with 1/6th of the coverage.
If digital is the right direction, the digital 48-sheet (D48) format is the direct equivalent: the same footprint as a traditional 48-sheet but with LED display technology and the ability to rotate creative.

Who Is the 48-Sheet Billboard For?
The 48-sheet is suitable for a variety of businesses and industries. The 48-sheet display provides ample space for impactful visuals, branding and messaging, making them effective for capturing the attention of a large and diverse audience at a relatively small cost.
Here are some examples of industries that often use 48-sheet billboards:
Real estate agents tend to use 48-sheet billboards to promote new residential or commercial property opportunities, often placing sites close to the development itself for maximum local relevance.
Fast-moving consumer goods (FMCG) brands typically use 48 sheets to advertise fast-moving products such as food, beverages and toiletries, where mass reach and high frequency build the brand familiarity that drives shelf selection.
Local and independent businesses may use 48-sheet billboards to create local visibility and generate interest, often selecting sites near their premises or along routes their target customers travel regularly.
How to Book a 48-Sheet Billboard
The UK's 48-sheet billboard inventory is controlled by a small number of large media owners, including JCDecaux, Clear Channel, Global Outdoor and Primesight. These companies manage thousands of sites across the country. To access that inventory, brands either negotiate directly with each media owner or work through a media agency that aggregates across networks.
Campaigns are typically booked on a 2-week cycle. Sites are sold by posting period, and popular locations, particularly those with high-traffic approaches to city centres, fill up quickly around peak retail periods such as Q4 and the summer.
At One Day Agency, we source, plan and book 48-sheet campaigns as part of a broader out-of-home strategy. We use audience data to identify the sites that reach your specific demographic rather than selecting on availability alone. This means the billboard placement reinforces the rest of your campaign, rather than running in isolation.

How to Measure Your 48-Sheet Campaign
Measuring the impact of out-of-home advertising requires a combination of industry data and campaign-specific tracking.
Route UK is the industry currency for OOH measurement in the United Kingdom. It provides audience data for individual billboard sites, including estimated weekly impacts, reach, and frequency figures based on real travel behaviour. This gives advertisers a clear picture of who is seeing the billboard and how often before the campaign launches.
During and after the campaign, several methods provide performance insight. Brand tracking studies measure shifts in awareness and perception among exposed audiences. For direct response objectives, QR codes printed on the creative allow you to attribute digital traffic directly to the physical placement. For ecommerce brands, geo-fenced digital campaigns running in the same areas as the physical billboard create a measurable online signal that correlates with OOH exposure.

““One of the oldest forms of advertising, poster or billboard advertising, is still king today amongst other media formats. Available in many options and covering a variety of audiences, it’s ideal for small brands for a more localised advertisement and big brands since it offers nationwide coverage.””
