Capture Attention from Tube Travellers With 12-Sheet Underground Advertising
One Day Agency helps ambitious brands reach London Underground audiences through strategically planned Tube advertising campaigns. We can advise on when 12-sheet posters are the right choice, how to incorporate them into your campaign and how they compare with other Underground advertising formats.
12-sheet Underground advertising is a way for businesses and brands to reach Tube network users with large-format, landscape poster displays. Positioned in selected stations, these ads offer the capacity for striking imagery, clear messaging and distinctive creatives, helping businesses make an impression in high-footfall public transport settings.
Because they’re larger than many traditional station posters, 12-sheets are often a strategic option for campaigns where visual space is essential, but where the brand doesn’t necessarily want or need the scale of a full platform takeover.
What Is 12-Sheet Underground Advertising?
12-sheets are landscape posters often displayed in walkways, concourses, along escalators and in other high footfall areas of the Tube, with each around three metres wide by 1.5 metres high. This provides considerable advertising space for brands who want their message to be heard.
Posters are found in selected stations, and unlike cross-track formats like 16-sheets and 48-sheets, they’re not always positioned directly opposite waiting passengers, and may provide more direct engagement opportunities.
Brands often find that 12-sheet formats are well suited to campaigns where they need lots of room to execute their creative ideas, and we’ve covered more options and formats through our London Underground advertising page.

How to Plan an Effective 12-Sheet Underground Advertising Campaign
Media planning involves multiple decisions, and the starting point is often to consider who your core audience is, what they will respond to, and where your promotions will generate all-important impressions.

Picking Stations Relevant to Your Audience
Understanding your target demographic can help determine which stations or areas within the Tube network will be best suited to your 12-sheet displays, and that could be based on stations in central London, those most used by commuters and professionals, services connecting with universities and residential areas, or lines used by tourists visiting attractions.
We can provide in-depth guidance based on your objectives, but you can also review TfL’s advertising information to get an idea of how Tube campaigns might work, and what sort of impact your 12-sheet promotions could achieve.

Campaign Creative Design
12-sheets are large, landscape promotional formats, which means there is room to develop distinctive, attention-grabbing imagery, often with clear text and a memorable message that commuters and travellers can digest and remember in little time.
The principles of effective outdoor advertising apply, with visuals that draw viewers’ attention to the main information or message, calls to action that can be understood in seconds, and imagery that makes passengers want to learn more about your brand, product or service.

![Advertising Costs]()
Advertising Costs
Tube advertising costs can vary considerably, depending on things like the station or stations you’d like to be positioned in, the number of 12-sheet placements you require, how long your campaign is due to run for, and whether there are spaces available in your preferred locations.
One Day’s explainer about Tube advertising costs provides further information about the elements that can impact Underground media budgets, although we’d recommend having a brand-specific media plan to help decide on whether to focus on selected stations or incorporate a wider range of placements.

![Combining Promotional Formats]()
Combining Promotional Formats
12-sheet campaigns can be part of multi-placement and multi-format campaigns, with options that include smaller eye-level station posters, digital screens, back-lit advertising placements, or both out-of-home and digital campaigns to reinforce brand recognition.
Each brand may have different requirements, but a larger 12-sheet might be a main campaign message, with smaller posters in other parts of the same station, or localised digital advertising that adapts depending on the conditions. Our guides to train and tram advertising formats and our TfL advertising service are well worth reviewing if you’d like more ideas.

Frequently Asked Questions.
-
A 12-sheet is a large, landscape-formatted poster shown in some London Underground stations, providing more space than smaller poster formats, but with the flexibility to be shown on locations like platforms, walkways and concourses, rather than on platforms alone.
Standard 12-sheet posters measure approximately three metres wide by 1.5 metres high, although this can vary slightly depending on the specific display. However, the layout gives capacity for prominent imagery, headlines and campaign messaging.
-
Tube campaigns vary substantially in cost because there are multiple potential displays, formats and promotional sizes to choose between, and even within 12-sheets you might find that costs differ between stations, times of the year, and whether displays are backlit or not.
Our advice is to contact One Day to chat about your budget and objectives, and we’ll start putting together suggestions to ensure you maximise visibility without overspending.
In some cases, we might also recommend using 12 sheets with other station formats, cross-track ads, digital displays and eye-level posters, recognising that more touchpoints and more frequency of exposure may tie into your brand objectives
