How OOH advertising works.

Updated May 2026 5 min read

Out-of-home (OOH) advertising means buying physical or digital placements that the public sees when they are outside their home: billboards, mall screens, lamp posts, transit wraps, and street furniture. This guide covers how OOH works globally: what is available, how pricing works, lead times, asset requirements, and what makes a campaign succeed across the markets we serve.

Section 01

What you can book.

The OOH market spans four main categories. Each suits different campaign goals and budgets. Click any card to browse live availability across all markets.

Section 02

How OOH pricing works.

Every OOH placement on Media.co.uk is priced per-flight in the local market currency. The price you see is the price you pay: no auction, no buried surcharges. Production and creative adaptation are quoted separately when needed.

Four factors determine what a placement costs:

Audience size

A digital screen at a busy mall reaches more people per hour than a roadside billboard on a secondary route.

Format

Digital and full-motion placements cost more than static. Larger formats cost more than single screens.

Flight length

Many operators discount 4-week flights versus 2-week.

Location prestige

Landmark locations carry premium rates.

Section 03

Lead times & booking flow.

Standard lead time is 5 to 10 working days from booking confirmation to flight start. High-demand digital landmarks need 2 to 4 weeks of advance notice. Specific lead times vary by country: see each country guide for local detail.

Each placement page lists the exact spec. These are the typical formats you will need to prepare for OOH campaigns. Our studio can adapt creative for any placement at additional cost.

Static placements

.AI, .PDF, or .EPS files at print resolution (300 DPI). CMYK with 5mm bleed.

Mall LEDs

.MP4 (H.264, 30fps) at exact panel resolution. Each mall has a different ratio. Check spec sheet.

Transit

Print-ready .PDF supplied 14 days before flight. Bus wraps require finished-art templates.

Section 05

Glossary.

The OOH industry has its own language. Here are the terms you will see across this site.

OOH: Out-of-Home advertising. Any advertising medium consumed outside the home.
DOOH: Digital Out-of-Home. The subset of OOH that's screen-based.
CPM: Cost per thousand. Total flight cost divided by total impressions, multiplied by 1,000.
Flight: The booked duration a campaign runs.
Reach: The audited estimate of how many unique people see a placement over a defined period.
Dwell time: How long an audience stays in proximity to a placement.
Impression: One viewing of an ad by one person.
Proof of posting: Documentary evidence (photos, screen logs) confirming a placement ran as booked.
Re-delivery: Re-running a campaign at zero cost if the original flight didn't run.

Section 06

Tips for OOH campaigns.

01
Match format to message
Single-image static suits brand awareness. Full-motion digital suits product launches.
02
Plan for cultural context
Local language creative outperforms translated copy in non-English-first markets.
03
Combine formats
A mix of premium DOOH plus high-frequency static gives better reach efficiency than either alone.
04
Book longer flights when CPM drops
If a 4-week CPM is meaningfully lower than 2-week CPM, the longer commit is the better trade.
05
Send a brief
Our planners can hand-pick the best placements for your audience, route, daypart, and budget.
