Ask ten media owners what a “standard billboard” measures and you’ll get six different answers. Sizes in outdoor advertising are shaped by local regulations, structure types, land availability and decades of habit.
That creates real problems. Designers build artwork at the wrong ratio, clients compare sites that aren’t comparable, and production quotes arrive for materials that don’t fit the frame.
This guide works through every major format, from highway spectaculars to lamp post buntings, covering typical dimensions, aspect ratios, viewing distance and artwork requirements for each.
Before We Start: Three Things To Know About Billboard Sizes
Sizes Are Conventions, Not Standards
Malaysia has no single national billboard size standard. Dimensions vary by media owner, local council approval and the physical site, so always request exact measurements for each booking.
Height Usually Comes First
Most Malaysian rate cards list dimensions as height by width, such as 20′ x 60′. Some vendors reverse this, and the mix-up is one of the most common causes of wrongly built artwork.
Visible Area Is Not Structure Size
The frame, lighting brackets and border reduce the printable area. Always confirm whether a quoted size refers to the full structure or the visible face.
- Confirm whether the size is height x width or width x height
- Ask for the visible area separately from the structure size
- Request bleed and safe-zone requirements before design begins
- Check whether the unit is feet, inches, metres or millimetres
- For digital, request pixel resolution, not just physical size
Standard Roadside Billboards
The workhorse of outdoor advertising. A flat, rectangular face mounted on a steel frame, usually beside a main road, facing one or both directions of traffic.
Typical Sizes
- 20′ x 60′ — the most common Malaysian roadside format
- 20′ x 40′ — smaller urban and secondary road sites
- 15′ x 40′ — tighter spaces and neighbourhood roads
- 10′ x 40′ — low-profile sites near residential areas
- 10′ x 20′ — compact boards on local streets and junctions
Aspect Ratio
The dominant 20′ x 60′ format runs at a 1:3 ratio. That long, letterbox shape suits horizontal layouts with a logo on one side and a headline across the rest.
Viewing Distance
Roadside boards are typically read from 50 to 300 metres away, often at speed. Text must be large, short and high-contrast to register within three to five seconds.
Artwork Notes
- Keep copy to seven words or fewer wherever possible
- Place the logo toward the edge that traffic approaches from
- Avoid thin fonts, script typefaces and light-on-light colour combinations
- Most printers work at scaled-down resolution, since billboards are viewed from distance
Supersize And Spectacular Billboards
The premium tier of static outdoor. Larger faces placed at high-profile locations, often along expressways or at major junctions, designed to dominate the view.
Typical Sizes
- 40′ x 60′ — a common Malaysian spectacular format
- 30′ x 90′ — extra-wide highway sites
- 30′ x 60′ — large-format urban placements
- 40′ x 80′ — flagship expressway structures
- 50′ x 100′ and above — rare, landmark sites
Why They Command Premium Rates
Size alone isn’t the reason. Spectaculars sit in locations with unobstructed sightlines and long approach distances, giving drivers several seconds of clear view rather than a glance.
Artwork Notes
The larger canvas tempts designers to add more. Resist it. The extra space should make the single message bigger, not make room for a second message.
Unipoles
A billboard mounted high on a single central steel pole, rather than a frame on the ground. Unipoles lift the face above trees, buildings and traffic for visibility across long distances.
Typical Sizes
- 20′ x 60′ — the standard Malaysian unipole face
- 30′ x 60′ — larger highway unipoles
- 20′ x 40′ — smaller urban unipoles
- 40′ x 80′ — large-format expressway structures
Configurations
- Single-sided — one face toward one traffic direction
- Double-sided (back-to-back) — faces both directions of travel
- V-shaped — two faces angled outward to catch approaching traffic
- Tri-vision or three-sided — faces covering a junction from multiple approaches
Viewing Distance
Height is the advantage. A tall unipole can be seen from several hundred metres away on an open expressway, far earlier than a ground-level board.
Artwork Notes
Because unipoles are often viewed from below at a distance, keep critical elements away from the bottom edge, where the frame and lighting brackets can obscure them.
Highway Gantries
A structure spanning the full width of an expressway, with the advertising face mounted directly above the carriageway. Drivers see it head-on for the entire approach.
Typical Sizes
- 15′ x 60′ — narrower expressway gantries
- 20′ x 80′ — a common wide-carriageway format
- 20′ x 100′ — spanning multiple lanes
- Sizes vary heavily with carriageway width at the specific site
Why Gantries Perform
Roadside boards are seen at an angle. Gantries sit directly in the driver’s line of sight, making them among the most effective formats per square metre of face.
Artwork Notes
- The extreme width suits horizontal storytelling across the frame
- Central placement of the key message works better than edge placement
- Many gantries are now digital, requiring video or static digital files instead of print
Overhead Bridge Banners
Panels mounted along pedestrian overhead bridges that cross main roads. Common across Malaysian cities, particularly in the Klang Valley.
Typical Sizes
- 10′ x 60′ — standard static overhead bridge panels
- 12′ x 60′ — slightly deeper formats
- 15′ x 60′ — larger digital overhead bridge screens
- Widths vary with bridge span, so confirm per site
Digital Overhead Bridges
Many overhead bridge sites have converted to LED. Typical digital resolutions sit around 384–448 pixels high by 1,792–1,824 pixels wide, keeping the same wide ratio as the static versions.
Artwork Notes
The very wide ratio of roughly 1:4 to 1:5 punishes vertical layouts. Design specifically for the format rather than stretching an existing landscape visual.
Building Wraps And Wall Banners
Large vinyl or mesh banners stretched across building facades. Sizes depend entirely on the building, so these are the least standardised format of all.
Typical Ranges
- 40′ x 60′ — mid-sized facade banners
- 50′ x 70′ — large office-tower facades
- 60′ x 100′ and above — full-building wraps
- Portrait formats are common where the facade is taller than it is wide
Material Choice Matters
- Mesh vinyl lets wind pass through, essential for high-rise sites
- Solid vinyl gives sharper colour but carries higher wind load
- Window-covering wraps use perforated film so occupants can still see out
Artwork Notes
Mesh loses some colour density, so boost contrast accordingly. Also account for windows, ledges and structural breaks that interrupt the face.
Rooftop Billboards
Structures mounted on building roofs, visible across the skyline and from elevated roads such as flyovers and expressways.
Typical Sizes
- 20′ x 60′ — common rooftop format
- 30′ x 60′ — larger city-centre sites
- 40′ x 80′ — landmark rooftop structures
Artwork Notes
Rooftop sites are often seen against sky, so avoid designs dominated by light blue or white backgrounds, which merge into the skyline on bright days.
Digital LED Billboards
LED screens replacing printed faces. The physical size matters, but for digital, pixel resolution is what designers actually need.
Common Landscape Sizes
- 20′ x 40′ — typical urban roadside screen
- 22′ x 44′ — common highway screen, often around 672 x 1,344 pixels
- 30′ x 60′ — large expressway screens
- 31.5′ x 63′ — spectacular digital sites, often around 600 x 1,200 pixels
Common Portrait Sizes
- 30′ x 20′ — upright roadside screens, often around 864 x 576 pixels
- 38′ x 25′ — tall urban screens, often around 720 x 480 pixels
- 60′ x 40′ — large portrait highway screens, often around 1,824 x 1,248 pixels
Understanding Pixel Pitch
Pixel pitch is the distance between LED clusters, measured in millimetres. Smaller pitch means sharper images at close range, but also higher cost.
- P3 to P6 — indoor and close-range screens
- P8 to P10 — urban roadside screens viewed at moderate distance
- P16 to P20 — highway screens viewed from far away
This explains why a huge highway screen might have lower resolution than a phone. At that viewing distance, finer detail is invisible anyway.
Digital Artwork Notes
- Supply artwork at the exact native pixel resolution of the screen
- Low-resolution screens blur fine text, so use larger fonts than on print
- Most slots run 10 to 15 seconds, so keep motion simple
- Avoid rapid flashing, which many councils prohibit for road safety
- Test how colours render on LED, which often looks more saturated than on screen
Lamp Post Buntings
Vertical banners attached to street lamp posts, usually in sequences along a road. Popular for events, local campaigns and festive greetings.
Typical Sizes
- 2′ x 5′ — small street buntings
- 2.5′ x 6′ — common municipal format
- 3′ x 7′ — larger main-road buntings
- Usually portrait orientation, often double-sided
Digital E-Buntings
LED versions replace printed fabric. A typical panel measures around 2,048 mm by 1,024 mm, with low native resolution, so artwork must be extremely simple.
Artwork Notes
Buntings are seen in sequence, so the strongest approach is repeated identical creative rather than a different message on each post.
Bus Shelter And Street Furniture Panels
Backlit panels built into bus shelters, kiosks and pedestrian walkways. Among the few outdoor formats read up close by pedestrians.
Typical Sizes
- 1.2 m x 1.8 m — the international six-sheet standard
- 1.0 m x 1.5 m — smaller street furniture panels
- 1.5 m x 2.0 m — larger shelter formats
Artwork Notes
Viewers stand within a few metres, so more detail is readable here than on any roadside format. This is where QR codes and offer details genuinely work.
Transit Advertising: Rail, Stations And Totems
Station environments carry a wide range of formats, from platform lightboxes to digital totems. Commuters have dwell time, which changes what artwork can achieve.
Typical Formats
- Six-sheet lightboxes — around 1.2 m x 1.8 m on platforms and concourses
- Digital totems — commonly 49″ to 55″ portrait screens at 1,080 x 1,920 pixels
- Platform wall panels — wide formats along platform edges
- Train wraps — full or partial exterior wraps sized to the carriage
- In-car panels — small interior cards above windows
- Station domination — wall, pillar and floor graphics across a whole station
Artwork Notes
- Portrait digital totems run at 9:16, the same as a phone screen
- Audio is usually muted, so design for silent viewing
- QR codes should be scannable from around 2.5 metres
Mall And Indoor Formats
Shopping centres offer a controlled environment with long dwell times and close viewing. Formats vary widely between malls.
Typical Formats
- Digital standees — commonly 55″ portrait screens
- Lightboxes — sizes vary, often wide landscape formats above walkways
- Pillar wraps — sized to each individual column
- Escalator and travelator panels — long, narrow side strips
- Hanging banners — suspended from atrium ceilings
- Lift door wraps — sized to each set of doors
Artwork Notes
Indoor formats are viewed close up under artificial light. Print quality matters far more than on roadside sites, so supply higher-resolution files.
Airport Formats
Airports combine long dwell times with a premium audience, and sizes vary considerably by terminal and location within it.
Typical Formats
- Bulkheads above check-in counters — very long, narrow strips
- Wall graphics in departure and arrival halls — sized to the wall
- Lightboxes at entrances and concourses
- Carousel domination — graphics surrounding baggage reclaim
- Glass panel graphics across concourse windows
- Digital screens in gate areas and walkways
Artwork Notes
Airport bulkheads can run at ratios beyond 1:25, extremely wide and shallow. Few existing visuals adapt well, so most need a dedicated layout.
Mobile Billboards
Advertising that moves, mounted on trucks, trailers or vehicles. Sizes are constrained by vehicle dimensions and road regulations.
Typical Formats
- Truck-side panels — commonly around 3 m x 6 m
- Mobile LED trucks — screens often around 2 m x 3 m to 3 m x 5 m
- Car-top LED screens — small displays on e-hailing and taxi roofs
- Full vehicle wraps — sized to the specific vehicle model
Artwork Notes
Vehicle wraps must account for doors, windows, handles and curves. Always request a vehicle template from the supplier rather than designing freehand.
International Poster Standards For Reference
International campaigns often arrive with artwork built to UK or US standards. These rarely match Malaysian sizes exactly, but they help when adapting global creative.
UK Sheet Sizes
- 6-sheet — 1.2 m x 1.8 m, portrait
- 48-sheet — 3.05 m x 6.1 m, landscape
- 96-sheet — 3.05 m x 12.19 m, extra-wide landscape
US Standard Sizes
- Bulletin — 14′ x 48′, the main US highway format
- 30-sheet poster — roughly 10′ x 23′
- 8-sheet junior poster — roughly 6′ x 12′
Adapting Global Creative
A US bulletin runs at roughly 1:3.4, close to the Malaysian 1:3 standard, so it adapts reasonably well. A UK 48-sheet at 1:2 needs significant reworking.
Viewing Distance And Legibility
Size only matters in relation to how far away the viewer is and how fast they’re moving. Rules of thumb vary between designers, but the principle is consistent.
General Legibility Guidance
- Letter height scales with distance — the further the viewer, the taller the text
- Roadside boards need text readable from at least 100 metres
- Pedestrian formats can use much smaller type, read from one to five metres
- Bold sans-serif fonts outperform serif and script at distance
- High contrast, such as dark on light or light on dark, matters more than colour choice
Speed Changes Everything
A driver at 90 km/h covers about 25 metres every second. A board visible from 200 metres gives roughly eight seconds of viewing, and most of that is peripheral.
Artwork Production Essentials
Getting the size right is only half the job. Production specs decide whether the finished print actually looks the way the design did on screen.
Resolution For Large Format Print
Billboards don’t need magazine-quality resolution. Artwork built at full scale typically works at 15 to 30 dpi, since nobody examines a highway board from arm’s length.
Scaled Artwork
Most designers work at a reduced scale, such as 1:10, and supply files at higher dpi. Confirm the scale with your printer before starting the file.
Bleed And Safe Zones
- Bleed extends the artwork beyond the trim edge, usually a few inches on large formats
- Safe zones keep text and logos away from edges the frame may cover
- Requirements differ by media owner, so request them per site
Colour And File Format
- Print artwork in CMYK, digital artwork in RGB
- Supply print files as high-quality PDF, TIFF or EPS
- Supply digital files as JPEG, PNG or MP4 at native resolution
- Convert all fonts to outlines before sending print files
- Check the maximum file size accepted by the media owner
Common Sizing Mistakes To Avoid
- Building artwork width by height when the vendor listed height by width
- Designing to the structure size instead of the visible area
- Stretching a landscape visual onto a portrait digital screen
- Using fine text on low-resolution LED screens
- Forgetting bleed, leaving white edges on the installed print
- Placing key messages where frames, brackets or lighting will cover them
- Assuming two sites are the same size because they share a format name

The Bottom Line
There is no universal billboard size, and anyone who tells you otherwise hasn’t handled enough rate cards. What exists instead is a set of common conventions that vary by format, owner and site.
Treat every size on this page as a starting point, then confirm the exact visible area, orientation and resolution for each site you book. That one step prevents most of the costly mistakes in outdoor production.
Get the size right, respect the viewing distance, and design for the format rather than forcing an existing visual onto it. The best billboards are built for their frame, not squeezed into it.
