Some poster sizes have stood the test of time because they work. Here is what our team orders most often and why each format earned its spot.
Some poster sizes have stood the test of time because they work. Here is what our team orders most often and why each format earned its spot.
Not all poster sizes are equally popular, and popularity is not arbitrary. The most-used sizes earned their status by being practical. They fit common surfaces. They print efficiently on standard equipment. They work at the viewing distances that matter. And they balance cost against visibility better than the alternatives.
We have been running outdoor campaigns for over a decade. In that time, we have produced campaigns using a wide range of formats. But certain sizes come up again and again across clients, markets, and campaign types. This guide covers those popular sizes in depth and explains why they dominate in each context.
These five formats account for the majority of what our team orders, prints, and hangs across the United States.
The 24×36 poster is the single most popular format for outdoor street advertising in the United States. Ask any print shop that serves advertising clients and they will confirm it. The format works for two practical reasons. First, it is large enough to attract attention from across a street or sidewalk. Second, it fits an enormous range of available wall surfaces without modification. A 24-inch wide poster fits between windows, above store entries, on loading dock doors, and on construction panels. At 36 inches tall, it fills the eye-level viewing zone without extending too high or too low.
For campaigns that need quantity, 11×17 is the format of choice. The tabloid size prints on equipment available at almost any commercial shop. Per-piece cost is low. Transport is easy. A stack of 500 pieces fits in a backpack. Our crews have saturated entire neighborhoods in Brooklyn and the Mission District in San Francisco using 11×17 posters in a single night. Volume creates presence. This is the format that makes that possible.
The 18×24 sits between tabloid and large-format in a sweet spot that many clients overlook. It is genuinely large at street level but does not require the investment of 24×36 printing. For campaigns with moderate budgets that still need to command attention, 18×24 delivers strong results. We use it heavily in neighborhoods like the Lower East Side in Manhattan, Logan Square in Chicago, and Silver Lake in Los Angeles.
The 27×40 one-sheet is the entertainment industry’s preferred format. Every major studio, record label, and event promoter uses it. The format was engineered to fit standard cinema lobby display cases, and it has been that standard for decades. If you are promoting any entertainment product and your campaign includes retail or venue placements, 27×40 is the size that fits the hardware. It is also a commanding format for street-level placements where you have the wall space.
40×60 is the format for when you need a placement to stop traffic. We use it selectively, on walls that can support the visual weight. Bowery in Manhattan. Melrose in LA. Wicker Park in Chicago. The format costs more per piece and requires careful surface selection, but the impact is proportional. A 40×60 on the right wall becomes a landmark for the duration of the campaign.
Why 24×36 Dominates
Across hundreds of campaigns, 24×36 is our single most-ordered format. It represents the optimal balance of visibility, surface compatibility, print cost, and transport practicality. When clients ask us what size to use and they do not have a strong reason to choose otherwise, we start with 24×36.
Popularity varies by campaign type. The most popular format for a music tour is not the most popular format for a brand launch. Here is how the breakdown looks in practice.
| Campaign Type | Most Popular Size | Second Choice | Why |
|---|---|---|---|
| Street / Outdoor advertising | 24 x 36 in | 18 x 24 in | Visibility from 10-25 ft, fits most surfaces |
| Music / Concert promotion | 11 x 17 in | 18 x 24 in | Volume, low cost, distributable |
| Film / Entertainment | 27 x 40 in | 24 x 36 in | Industry standard display sizes |
| Brand campaigns | 24 x 36 in | 40 x 60 in | Visibility, brand presence, wall impact |
| Retail / POS | 22 x 28 in | 18 x 24 in | Standard retail display frame sizes |
| Event promotion | 11 x 17 in | 24 x 36 in | Budget efficiency plus key placements |
| Trade show / Exhibit | 36 x 48 in | 24 x 36 in | Booth display system compatibility |
Popularity in poster sizing comes from four factors. A size that scores well on all four becomes a standard. A size that fails on one becomes a niche format.
Surface compatibility. Popular sizes fit the most common display surfaces. The 24×36 works on plywood hoarding, blank walls, concrete surfaces, and most building sides. Unusual sizes often do not fit standard surfaces cleanly.
Print equipment standardization. Popular sizes align with common print equipment output sizes. Wide-format inkjet printers run on roll stock in standard widths: 24 inches, 36 inches, 42 inches, 60 inches. Sizes that match these widths minimize paper waste and reduce print cost.
Cost efficiency. Popular sizes hit a cost per square inch that makes campaigns economically viable. Extremely small sizes cost nearly as much to set up as larger ones. Extremely large sizes cost too much per piece for volume campaigns. The sweet spot sizes balance cost against visual area.
Visibility performance. Popular sizes are readable at the distances where most viewing happens. An 11×17 works at arm’s length. A 24×36 works from across a street. A 40×60 works from a half-block away. The distances align with how people move through and look at urban environments.
The most popular size in one neighborhood is not necessarily the most popular in another. Here is how environment shapes format choice in specific urban contexts we know from field work.
In tight, walk-up urban residential blocks like the West Village in Manhattan, Carroll Gardens in Brooklyn, or Los Feliz in Los Angeles, the available surface area is limited. Window frames are narrow. Building surfaces are often brick with irregular spacing that does not accommodate large formats cleanly. The popular size in these environments is 18×24 because it fits window glass, bulletin boards at the local coffee shop, and the small blank wall sections between buildings. A 24×36 is possible but often feels oversized relative to the intimate scale of the architecture.
The Bowery in New York, Fairfax in Los Angeles, Milwaukee Avenue in Chicago. These are high-volume pedestrian commercial streets with wider surfaces, construction barriers, and the kind of ambient visual competition that demands size. The popular format here is 24×36 minimum, with 40×60 at premium locations near intersections. Anything smaller than 18×24 gets lost in the visual noise of a busy commercial block.
University and college campuses are bulletin board territory. The posting culture creates an network of 11×17 formats covering every available display surface. Students walk close to bulletin boards specifically to read what is posted. The 11×17 serves this viewing behavior well. Anything larger is generally unnecessary and can be hard to post within the bulletin board format. The exception is large, open kiosk structures on some campuses, which can accommodate 18×24 posters alongside standard board postings.
Festival environments create temporary wall space. Vendors run tents, banners, and booth panels that can hold 24×36 and 18×24 posters effectively. High-traffic walkways between stages or vendor rows favor 24×36 for visibility. Vendor booth walls are commonly marked with 18×24 campaign materials. For brands running activations at outdoor events, the popular double-format approach of 24×36 at key walkway intersections plus 18×24 inside booths and vendor areas consistently outperforms any single-format approach.
When designing posters digitally, the popular size formats translate into pixel dimensions based on the intended print resolution. For outdoor large-format printing at 150 dpi, here are the pixel dimensions for the most popular sizes:
These are minimum resolution dimensions for print-quality outdoor output. For posters viewed at close range, use 300 dpi instead of 150, which doubles both pixel dimension values and significantly increases file size.
Resolution vs. Size: The Most Common Mistake
Clients regularly send us design files at 72 dpi thinking they look fine on screen. On screen, 72 dpi works. In print at 24×36 inches, 72 dpi produces a visibly pixelated result. Always design at 150 dpi minimum for large-format outdoor printing. 300 dpi if the poster will be viewed within 5 feet.
Outside the United States, ISO-standard sizes dominate. The most popular international poster formats used in street advertising are A1, A2, and B1.
A1 (59.4 x 84.1 cm / 23.4 x 33.1 inches) is the most popular single poster size for street advertising in European markets. It is the closest ISO equivalent to the US 24×36 format.
A2 (42 x 59.4 cm / 16.5 x 23.4 inches) is the mid-format equivalent of the US 18×24. Used heavily for concert promotion and event marketing across Europe and Australia.
B1 (70.7 x 100 cm / 27.8 x 39.4 inches) is specifically popular for transit advertising and outdoor kiosk formats in European cities. The B1 size is roughly equivalent to the US 27×40 one-sheet in visual presence.
Our process is simple. We start with the viewing environment. Then we look at available surfaces. Then budget. Then the creative requirements. Size is a production decision, not a preference. The environment tells us what size to use. We work backward from there.
When a client insists on a size that does not match their environment or budget, we explain the tradeoffs clearly. A 40×60 campaign with 50 pieces costs more and covers less ground than a 24×36 campaign with 200 pieces at the same total budget. For some objectives, dominating 50 locations with 40×60 formats is the right call. For others, 200 locations with 24×36 builds more awareness. We help clients make that call with real data from comparable campaigns.
24×36 inches is the single most popular format for outdoor street advertising in the United States. It combines strong visibility, surface compatibility, and manageable print costs better than any other format.
Concert venues vary. Many use 11×17 for street distribution and 18×24 or 24×36 for venue lobby and bar placements. The specific size depends on the venue’s display hardware and the promoter’s budget.
No. A 27×40 poster (1,080 square inches) is about 25% larger in area than a 24×36 (864 square inches). The 27×40 is notably taller and slightly wider. Both are considered large-format poster sizes for professional use.
11×17 is the most affordable format among popular poster sizes. Wide availability of tabloid-capable printers and low paper cost make 11×17 the budget-friendly choice for volume campaigns.
Music campaigns typically use 11×17 for high-volume street coverage and 24×36 for key placement locations in record stores, venues, and high-traffic walls. Some campaigns use both sizes from the same print run to maximize coverage.
22×28 is the standard for retail POP displays. Most pharmacy, grocery, and big-box retail display frames are built to accommodate 22×28 posters. For smaller retail contexts, 18×24 and 11×17 are also widely used.

The sizes themselves are standardized nationally. What changes by city is the relative availability of wall space for different sizes. Dense urban environments like Manhattan support smaller sizes in high volume. Larger cities with more open wall space see more 40×60 usage.
