Mobile Billboards vs Fixed Outdoor Billboards: Daily Costs and Campaign Control (Hong Kong 2026)

Comparisons often assume fixed billboards are expensive and vehicles cheap. Public prices converted to daily costs suggest a less obvious result: Mong Kok static sites at HK$80,000–150,000 for four weeks average about HK$2,857–5,357 daily, close to LED truck references of HK$2,500–5,500.The useful question is what each price buys.

Key takeaways

Daily costs can be similar: Mong Kok static billboards average HK$2,857–5,357 daily versus LED vehicles at HK$2,500–5,500. Hours and location flexibility distinguish the offers.
Premium fixed sites cost far more: Public references include Sogo LED at HK$200,000–400,000 for two weeks (HK$14,286–28,571 daily), Harbour Luminous floating LED at HK$250,000–500,000 for two weeks and Hong Kong International Airport at HK$300,000–700,000 for four weeks. One agency reports an average Hong Kong outdoor campaign budget around HK$447,000.
Difference 1: hours.A fixed billboard occupies one site throughout the day; vehicle packages commonly offer eight hours between 10am and 10pm or nine hours from arrival, with routes and timing selected for the campaign.
Difference 2: booking period.Fixed sites commonly book for two to four weeks; vehicles often have a one-day minimum.
Difference 3: content.Static billboards require reprinting and installation; LED vehicles can switch MP4 or JPEG files the same day.
No shared impression audit standard: Hong Kong lacks a shared public OOH impression audit standard, so CPM comparisons depend on consistent footfall assumptions.

1. Compare using daily costs

Why headline prices are not comparable

Two- or four-week billboard quotes and daily vehicle quotes use different units. Start by dividing each total by its actual days, then checking what each day includes.

Published fixed-billboard rates

One Hong Kong outdoor agency's public pricing spans around HK$30,000 to over HK$700,000:

Format and location	Booking period	Published price, HK$
Programmatic DOOH: citywide digital-screen network	Two weeks	30,000 – 80,000
Digital billboard: Causeway Bay	Two weeks	80,000 – 180,000
Digital billboard: Central / Admiralty	Two weeks	120,000 – 250,000
Static billboard: Mong Kok	Four weeks	80,000 – 150,000
Outdoor television network	Four weeks	50,000 – 120,000
LED facade: Tsim Sha Tsui Centre / Empire	Two weeks	180,000 – 350,000
Sogo LED wall	Two weeks	200,000 – 400,000
Harbour Luminous floating LED	Two weeks	250,000 – 500,000
Hong Kong International Airport	Four weeks	300,000 – 700,000

Another agency lists general billboards around HK$30,000–300,000 monthly depending on location, static/digital/programmatic format, size and duration. Adintime lists traditional billboards around HK$150,000 to over HK$1 million and digital/LED around HK$30,000 to over HK$1 million, with reported average 2023 DOOH campaign spending about HK$43,000.Agency information also reports an average Hong Kong outdoor campaign budget around HK$447,000 and airport placements around HK$500,000.

Non-core New Territories or Hong Kong Island locations can be cheaper: community mall lightboxes or local bus-stop advertising may be around HK$10,000–30,000 monthly. Premium sites can be much higher: a 15-second slot opposite Sogo is reported around HK$200,000–800,000 monthly, while large facade billboards near the Cross-Harbour Tunnel often exceed HK$500,000 and top sites can reach seven figures.

Published mobile billboard rates

LED references commonly range from HK$2,500–5,500 daily. Platforms also list HK$5,500 daily, around HK$35,000 weekly (HK$5,000 per day) and HK$90,000–105,000 monthly (HK$3,000–3,500 daily). Tiers include HK$4,500 daily from seven days, HK$3,500 from 14 and HK$2,800 from 28, plus about HK$4,800 design and HK$20,000 printing/installation.

Full roadshow packages are different: one supplier lists HK$33,000 per weekday, HK$88,000 weekly (HK$12,571 daily) and HK$268,000 for four weeks (HK$9,571 daily), including driver, emergency coordinator, two 50-inch TVs, LED banners, generator, air conditioning, 4G, carpet and graphics.

Daily cost comparison

The figures below divide the cited totals directly by their days:

Medium and format	Published total	Days	Daily equivalent
Programmatic DOOH network	30,000 – 80,000	14	About 2,143–5,714
Static billboard: Mong Kok	80,000 – 150,000	28	About 2,857–5,357
LED mobile billboard: daily hire	2,500 – 5,500	1	About 2,500–5,500
Mobile billboard: 28-day tier including allocated production	103,200	28	About 3,686
Outdoor television network	50,000 – 120,000	28	About 1,786–4,286
Digital billboard: Causeway Bay	80,000 – 180,000	14	About 5,714–12,857
Digital billboard: Central / Admiralty	120,000 – 250,000	14	About 8,571–17,857
Mobile billboard: one-week roadshow package	88,000	7	About 12,571
Hong Kong International Airport	300,000 – 700,000	28	About 10,714–25,000
Sogo LED wall	200,000 – 400,000	14	About 14,286–28,571
Harbour Luminous floating LED	250,000 – 500,000	14	About 17,857–35,714

Three findings from the comparison

The table reveals three points:

First, entry-level fixed and mobile daily costs overlap.Mong Kok static sites at HK$2,857–5,357 daily, programmatic DOOH at HK$2,143–5,714 and outdoor TV at HK$1,786–4,286 overlap LED vehicle references of HK$2,500–5,500.Fixed billboards are not always more expensive.

Second, premium locations create the largest gap.Sogo LED averages HK$14,286–28,571 daily and Harbour Luminous HK$17,857–35,714, several times ordinary vehicle hire. These placements sell landmark status and brand presence as well as exposure.

Third, full roadshow vehicles overlap digital-billboard pricing.HK$88,000 a week averages HK$12,571 daily, overlapping Causeway Bay digital references of HK$5,714–12,857. The vehicle package includes operational staff, TVs, power, air conditioning and graphics, so it is a different service.

Compare what a similar daily cost buys.The next section examines that. For comparisons including buses, MTR, trams and taxis, see Mobile Billboards vs Bus, MTR Lightbox, Tram and Taxi Advertising: Costs and ROI。

2. What does the same daily spend buy?

Difference 1: fixed-site presence versus eight or nine vehicle hours

This easily overlooked distinction matters.A fixed billboard occupies one location throughout the day, including low-traffic hours. Digital sites may rotate advertisements, so confirm the actual display share and operating hours.A mobile billboard commonly provides eight hours daily, sometimes restricted to 10am–10pm, while another model provides nine service hours from arrival, excluding outward travel.

More hours are not automatically better: an office audience may be most accessible at lunch and after work, around four hours total; families may concentrate on weekend afternoons and evenings.Vehicles can concentrate their eight or nine hours on relevant periods, while a fixed booking covers the site's broader schedule.The comparison can change when measured per useful audience hour.

Difference 2: location versus route

Fixed sites repeatedly reach the same road's visitors. Vehicles can focus on an opening's neighbourhood, appear near a concert at dispersal or cover two or three shopping areas in different time slots, subject to road access and traffic restrictions.

A practical constraint: many core roads do not allow extended stopping.The Road Users' Code prohibits stopping in active restricted zones, at bus/minibus stops and taxi stands, in tunnel/control areas and on expressways. Typical posts indicate red 7am–midnight, yellow 7am–7pm, green 8–10am and 5–7pm, grey other times; signs govern. Vehicles therefore mainly circulate in core districts. For planning, see Routes, Timing and Coverage Strategies。

Difference 3: booking periods and creative changes

Item	Outdoor billboards	Mobile advertising trucks
Minimum period	Usually 2–4 weeks	Usually 1 day
Static creative changes	Reprinting and replacement	Vehicle graphics require replacement; LED requires new files
Digital creative changes	Possible, subject to scheduling and share of display time	Same-day changes and multiple versions
Same-day creative testing	Depends on the platform and booking	Possible with separate QR codes

For a one-day opening, a two-week fixed booking may buy more time than needed, while vehicles can cover just launch day and the first weekend. For three months of continuous presence, fixed sites may be better value. For LED versus printed graphics, see LED Trucks vs Traditional Vehicle Advertising。

Difference 4: staffed interaction

A vehicle can support distribution, trials and QR gift redemption at an authorised site. Our Mini promotional truck carries up to 1,000 kg with solar power and Wi-Fi for supplies; a Mobile showroom truck can add shelves, trial areas and checkout equipment. Include staffing: public references are about HK$800 daily for a supervisor, HK$150 hourly for an assistant, HK$200 for a promoter and HK$400 upwards for a model.

3. District pricing and location choice

District averages and individual locations

An agency publishes these district references: Central around HK$170,000, Causeway Bay HK$130,000, Mong Kok HK$65,000 and Tsim Sha Tsui HK$80,000–200,000.Individual location references include:

District and location	Published price, HK$
Central: Queen's Road Central / Des Voeux Road Central LED	100,000 – 250,000
Causeway Bay: Sogo facade LED screen	200,000 – 400,000
Causeway Bay: Hennessy Road / Yee Wo Street	80,000 – 180,000
Mong Kok: Nathan Road / Sai Yeung Choi Street LED	40,000 – 100,000
Tsim Sha Tsui: Harbour Luminous / Tsim Sha Tsui Centre	80,000 – 500,000
Wan Chai: Gloucester Road / Harbour Road	60,000 – 150,000
Programmatic DOOH: citywide screen network	30,000 – 150,000

One source reports over one million daily shopping visits in Causeway Bay. Sogo LED is typically quoted around HK$200,000–400,000 for two weeks, depending on rotation share and season, with negotiated 48–72-hour exclusive bookings also possible.

The important location question

Ask where your audience appears, and at what time. Central attracts office workers at weekday lunch but is quieter on Sundays; Mong Kok has steadier week-round younger mass-market traffic; Tsim Sha Tsui has more visitors. Concentrated audiences can benefit from fixed repetition; dispersed audiences favour route flexibility.

Also consider the booking commitment: fixed sites usually require a complete booking period, even if you need only three days. A vehicle budget can be divided among key dates in several areas.

4. Five objectives and suitable choices

1: a one- to three-day event → mobile billboard

Openings, launches and promotional weekends suit daily bookings rather than a typical two- to four-week fixed commitment. See A practical three-day store-opening plan。

2: long-term landmark presence → fixed billboard

Flagship locations and premium brand positioning can benefit from Sogo, Harbour Luminous or airport symbolism that a vehicle cannot reproduce. Premium examples average roughly HK$14,286–35,714 daily.

3: changing campaign messages → LED vehicle

Offers, daily discounts, countdowns and phased messages can change by file replacement. Static sites need reprinting, while digital sites depend on scheduling and display share. For seasonal planning, see Seasonal Promotional Vehicle Planning Schedule。

4: on-site interaction → promotional vehicle

Distribution, trials, redemption and registration create countable contact beyond a display alone. For industry approaches, see Mobile Promotion Across 10 Industries。

5: several districts → mobile billboard or programmatic DOOH

A DOOH network, quoted around HK$30,000–80,000 for two weeks, covers many fixed screens, with timing options dependent on inventory and booking. A vehicle offers fewer locations but a custom route and selected service hours.Consider a network for breadth and a vehicle for route-specific activity.

5. Three combined approaches

1: a landmark foundation plus tactical vehicle activity

Maintain a core billboard for quarterly brand presence, then add vehicles on key dates, such as launch week around three branches. Use consistent creative across both.

2: divide an entry-level budget between both formats

Mong Kok static daily equivalents of HK$2,857–5,357 overlap LED hire at HK$2,500–5,500, so a split allocation may combine repeated fixed-site presence with selected vehicle routes and hours. Check minimum bookings and production charges before assuming the same total budget will cover both.

3: divide time and geography

Keep the fixed site at the core landmark and use vehicles in neighbourhoods, estates and narrow streets beyond its reach, choosing a Mini promotional truck where large trucks cannot enter. At night, use an LED advertising truck for illumination: common outdoor specifications start at 5,000 nits, typically 5,000–6,500, with stronger contrast in lower ambient light.

6. Measurement: two issues first

No shared public impression audit standard

CPM comparisons require credible exposure estimates, but Hong Kong lacks a shared publicly audited OOH audience standard comparable to Route in the UK or Geopath in the US. Reported reach definitions differ. Apply the same footfall assumptions and adjustment factors to both media and disclose them.

“97% recall” is not Hong Kong data

The frequently quoted figure is attributed to Transportation Advertising Council of America research reported in July 2002 in Outdoor Advertising. American Trucking Association material also reported 91% noticing truck text and graphics. These US findings date to around 2002 and concern a different environment.Use them as context, not forecasts or guarantees.For the full source trail, see Public case studies and the “97% recall” claim。

A practical four-level framework

Execution: Request posting photographs for fixed sites and route/time/stop records plus photos/video for vehicles. Some fleets provide real-time GPS across all vehicles.
On-site activity: Staffed vehicle events can count contacts, participants, giveaways and scans. RoadAds' public example reports over 40 locations, 30,000 contacts and 6,000 participants, with 35% expressing further interest. Interest is distinct from completed purchases.
Attribution: Both media can use dedicated QR codes, medium-specific offers or short URLs. LED vehicles can test two creatives with separate QR codes on the same day.
Exposure: Estimated, with explicit assumptions kept consistent throughout.

7. Vehicle-specific regulatory considerations

Physical limits for graphics and screens

The Road Traffic (Construction and Maintenance of Vehicles) Regulations require do not obstruct the driver's view, mandatory lights or reflectors, or the registration number with secure installation. LED fitting involves modification; Transport Department guidance calls for manufacturer or agent consultation beforehand because warranties may be affected.

Stopping rules

Core roads commonly restrict stopping, and the Code advises against stopping near school entrances. Vehicles mainly circulate there; use malls, private sites, event venues or authorised spaces for stationary displays.

Sound

Vehicle audio is subject to Noise Control Ordinance (Cap. 400) section 5(1)(b): amplified noise causing annoyance amounting to a nuisance in domestic premises or public places is unlawful at any time, including vehicle speakers. No acceptable decibel ceiling is specified. A silent billboard does not introduce this audio issue.

Shared content regulation

Separate laws govern both media. Under Cap. 371, smoking-product trademarks or brand names can make an advert a smoking-product advertisement, with a stated maximum HK$50,000 fine. First-hand residential advertisements follow Cap. 621 saleable-area requirements, with relevant contraventions constituting offences. See Twenty frequently asked questions about mobile promotional vehicles。

8. Five common mistakes

1: assuming fixed billboards always cost more

Entry-level daily equivalents overlap vehicle hire: Mong Kok static HK$2,857–5,357, programmatic DOOH HK$2,143–5,714 and outdoor TV HK$1,786–4,286. Premium landmark sites drive the highest prices.

2: comparing daily cost without useful hours

A fixed site and eight or nine vehicle hours serve different schedules. If your audience mainly appears during four lunch/after-work hours, the remaining time may have less value. Compare cost per useful audience hour。

3: buying a long booking for a short objective

A two- to four-week fixed booking may exceed a one-day opening's needs. Consider daily vehicle hire for the key dates.

4: chasing the busiest location

Sogo's two-week reference is HK$200,000–400,000 and one source reports over a million daily shopping visits in Causeway Bay, but traffic has little value if it is not your audience.Find your audience before maximising footfall.

5: treating the formats as mutually exclusive

Similar entry-level daily equivalents suggest a combined allocation may work, providing fixed repetition and flexible routes. Confirm actual booking minimums and all-in costs before dividing the budget.

9. Frequently asked questions

Are mobile billboards really cheaper than fixed outdoor billboards?

Not necessarily at entry level. Mong Kok static at HK$80,000–150,000 for four weeks averages HK$2,857–5,357 daily; programmatic DOOH at HK$30,000–80,000 for two weeks averages HK$2,143–5,714; LED vehicles commonly range HK$2,500–5,500 daily. Premium sites differ: Sogo at HK$200,000–400,000 over two weeks averages HK$14,286–28,571. Compare the service bought, not just price.

What is the fundamental difference?

Hours, locations and creative control. A fixed site provides repeated presence at one location, with digital operating hours and rotation to confirm. Vehicles commonly provide eight hours between 10am and 10pm or nine from arrival on a chosen route. LED files can change the same day, while static artwork needs replacement. Vehicles can also support staffed distribution and interaction at authorised sites.

Which suits a limited budget?

For one to three days, daily vehicle hire avoids a longer fixed commitment. For three months or more, entry-level fixed sites may be economical. For several districts and a budget in the tens of thousands, compare a DOOH network around HK$30,000–80,000 for two weeks with vehicles: a network offers many fixed points with booking-dependent scheduling, while vehicles offer more direct route control over fewer locations.

How much do billboard prices vary by district?

Published district averages include Central HK$170,000, Causeway Bay HK$130,000, Mong Kok HK$65,000 and Tsim Sha Tsui HK$80,000–200,000. Listed examples include Central LED HK$100,000–250,000; Sogo HK$200,000–400,000; Hennessy Road/Yee Wo Street HK$80,000–180,000; Nathan Road/Sai Yeung Choi Street LED HK$40,000–100,000; Tsim Sha Tsui HK$80,000–500,000; and Gloucester Road/Harbour Road HK$60,000–150,000. Confirm each booking period. Non-core community lightboxes may be HK$10,000–30,000 monthly.

Do vehicles generate enough exposure?

There is no single reliable answer because Hong Kong lacks a shared public OOH audience audit standard and definitions differ. Fixed sites repeatedly reach one area; vehicles reach several roads during selected hours. Compare with consistent footfall assumptions and adjustment factors, disclosed in the report. Countable interactions and trackable responses provide more direct evidence than impressions alone.

Have mobile billboards replaced fixed outdoor sites?

No. Landmark locations offer symbolic brand presence and sustained repetition around flagship sites. Vehicles do not reproduce a Sogo, Harbour Luminous or airport placement. An agency-reported average outdoor campaign budget around HK$447,000 also illustrates the continuing role of fixed media.

Can we use both?

Yes: maintain a landmark site and add vehicles on key dates; divide an entry-level budget between fixed repetition and selected routes; or use fixed sites centrally and vehicles in neighbourhoods, with LED at night. Keep branding consistent. Similar daily equivalents do not guarantee both fit the same budget; check minimum periods and production charges.

Can a truck stop in a core shopping area?

Often not. The Road Users' Code prohibits stopping in active restricted zones, at bus/minibus stops or taxi stands, in tunnel/control areas, on expressways and crossings, and advises against stopping near school entrances. Typical post colours are red 7am–midnight, yellow 7am–7pm, green 8–10am and 5–7pm, grey other hours; signs govern. Use authorised sites for stationary displays.

What additional rules apply to advertising trucks?

Keep driver visibility, lights, reflectors and registration numbers clear and install securely under vehicle construction and maintenance rules. Consult the manufacturer or agent before LED modifications, which may affect warranties. Audio must not cause nuisance under Noise Control Ordinance section 5(1)(b). Advertising-content restrictions, such as smoking-product and first-hand property rules, apply to both media.

How do I choose the better option?

Ask how long the activity runs, where and when the audience appears, and whether changing content or staffed interaction is needed. Vehicles generally suit three days or fewer, selected routes/hours and interaction; consider fixed sites for three months or more and concentrated recurring audiences. Digital fixed sites may also support changing content, subject to booking. Compare total cost and useful audience hours afterwards.
