DOOH creative design 2026: rules, formats, mistakes

Creative that works great on Instagram looks like a disaster on a DOOH screen. A person looks at a feed banner for 3 seconds from 30 cm away. They look at a roadside LED screen for 1.5 seconds from 30 meters, in passing, from a car, in the rain. It is a fundamentally different medium. Let's break down the rules that really determine whether your clip gets noticed — and a checklist for designers in 2026.

The basic principle: 6 words, 1 idea, 0.5 seconds

The standard contact time with an outdoor screen:

• On a highway (speed 60 km/h): 1–1.5 seconds.
• In a shopping mall: 2–3 seconds.
• At a gas station (average contact time with the video sequence): 8 seconds.
• In a checkout queue: up to 30 seconds.

In 1.5 seconds a person will not read three sentences. They will read 6–8 words in a large font. That's physiology, not marketing.

Rule 1. Font — at least 1/10 of the screen height

A general rule that works: the height of the main text should be no less than 10% of the screen height. Otherwise, from a distance of 20–30 meters it blurs into mush. For a 6×3 m LED that means the main message must be at least 30 cm tall.

On programmatic screens in malls, where the distance is 5–10 m, you can work with 1/15 — but even there, smaller = risk.

No serif fonts, no italics, nothing decorative — sans-serif with a heavy weight (Roboto, Inter, Manrope, Druk Wide). Serifs blur at speed.

Rule 2. Contrast 7:1, no less

White text on yellow = you've thrown away your money. Dark blue on black = the same. The design must have a text-to-background brightness ratio of at least 7:1, and in bright sunlight — 10:1.

The best combinations:

• White on dark red, dark blue, black.
• Black on yellow, white.
• Yellow on black, blue.

The worst:

• Gray on gray.
• Red on blue (vibration).
• Any pastel on pastel.

This isn't a matter of taste. Check the Black & White filter in Photoshop — if your colors turn into gray mush, the same will happen in the sun.

Rule 3. One message, one CTA

The general command: "don't try to say everything." A billboard or screen fits one idea. Not three. Not two. One.

The correct structure:

1. Brand / logo — 15% of the area, in a corner.
2. The main idea — 60% of the area, in the center.
3. CTA — 15% of the area, at the bottom or in a corner (QR, website, phone).
4. Address/details — 10% of the area, small.

If you feel like adding more — cut it.

Rule 4. A CTA that works hands-free

A classic mistake: "Call 050-XXX-XX-XX." The person is in a car. Or carrying bags in a mall. They won't call.

What works as a CTA:

• A large QR code (at least 25% of the screen height), with a clear "Scan" instruction next to it.
• A short branded Google query (like "google HostAd"). It engages short-term memory.
• An Instagram handle — for the 18–35 audience.
• A website name that's simple to spell — no hyphens or abbreviations. hostad.io reads cleanly, ad-net-platform-2026.com.ua does not.

A separate life hack: prepare 2 versions of the creative — one for a sunny day and one for an overcast/rainy one. For rain — a bigger font, a simpler CTA, because the person looks for less time. Upload both into the campaign and alternate them.

Rule 5. Motion depends on contact time

For locations with short display time (highway, façade) — use static or partial motion (one element moves: the logo, an arrow, a number).

For places with long contact (a waiting area, a checkout queue) — use full video of up to 15–30 seconds.

Mistake №1: running a 30-second clip on a highway. The person will see 1 second — and it will be a random second with no message. For a highway, adapt: a 5-second loop, with at least one readable message in each second.

Mistake №2: pure static on a mall screen where people stand on an escalator for 20 seconds. Here, motion already pays off.

Rule 6. Orientation and resolution — exactly

DOOH screens come in very different shapes. Some are vertical (citylight, metro), some horizontal (façade, pylon), some square (malls). Don't try to make "one creative for all formats" — the text will start getting cropped.

Standard formats worth planning for in advance:

Format	Size (px)	Orientation
Billboard 6×3 m (video version)	1920×960	horizontal
Citylight	1080×1920	vertical
LED panel on a pylon (gas station)	1080×1920 or 1280×720	vertical / horizontal
Indoor mall, video screen	1920×1080	horizontal
Indoor gas station (waiting area)	1920×1080	horizontal

Based on the screen's characteristics, the placement of key messages needs to be adapted so they are visible. On HostAd, the exact dimensions and proportions are listed for each surface — use them when preparing your artwork, not an "average standard."

Checklist before submitting your creative

Before you upload to the platform, run through the list:

• The key message is readable from 30 m (test: shrink it on screen to 200 px and look).
• Text-to-background contrast ≥ 7:1.
• The creative has no more than 6–8 words of main text.
• The CTA is a QR or a short brand query, not a phone number.
• The video is sized for the slot duration (5/8/10/15/30 s).
• The logo takes 15% of the area, in a corner, not dominating.
• No italics, no serifs, no decorative fonts.
• Checked in black-and-white — the message is still readable.
• Checked on a smartphone (preview) — recognizable at 200×200 px.
• All formats ready (horizontal, vertical, square if needed).
• File in MP4 H.264 format; static — JPG/PNG no larger than 10 MB.

Common mistakes

1. A tiny QR. A QR smaller than 1/4 of the screen height won't scan from 5 m. Enlarge it.
2. Interlacing with photos of people. Complex photos "blur out" on DOOH. Better — a color block + text.
3. Animated fade transitions. On LED screens this looks like a technical malfunction.
4. A Ukrainian brand in the Latin alphabet. If your brand is "Сільпо," don't write "Silpo" — a Ukrainian-speaking audience reads the Cyrillic faster.
5. A CTA with a www. website address. On DOOH, www. just eats up space. hostad.io is enough.
6. The same creative for rain and sun. In the morning, bright sun kills a low-contrast palette. Make a higher-contrast version for the daytime slot.

Summary

Design for DOOH is not design for social media at a higher resolution. It is a separate genre with its own rules:

• 6–8 words, 1 idea.
• Font 1/10 of the screen height.
• Contrast 7:1.
• QR instead of a phone number.
• Adaptation to the format and contact time.

If the creative is built to these rules — you get real effectiveness. If not — you're paying for impressions that no one will read.

A ready creative plus the urge to test it — head to the HostAd map: filter surfaces by city and budget, pick 2–3 formats, upload 2 versions of the creative and book for a month. After 4 weeks you'll see which version works. More on the self-service buying process itself — in the article on programmatic DOOH in Ukraine.
