Creative Guidelines

Last updated: 28 August 2026

Every submission is reviewed by a person. These are the rules that review applies.

Accepted files

PNG, JPEG, WEBP, or SVG. Maximum 15 MB. SVG files are sanitised on upload: scripts, event handlers, and external references are stripped.

Your artwork is printed at real physical size. For small territories, use a logo, an icon, or one to three words. We show you an estimated legibility rating and letter height before you pay — it is an estimate, but it is an honest one.

Raster images below roughly 12 dpi at final printed size are refused rather than silently upscaled.

Not accepted

• illegal content, or content promoting illegal goods, services, or activity
• scams, deceptive offers, fake claims, malicious URLs, malware
• pornographic or sexually explicit imagery
• hateful, extremist, or discriminatory content, and content targeting protected groups
• threats, harassment, or content targeting a private individual
• infringement of trademarks, copyright, or image rights you do not hold
• impersonation of a person or organisation without authorisation
• anything the owner of the physical billboard refuses

Regulated categories

Some categories are restricted or prohibited for outdoor advertising depending on the city and applicable law. For the Milan campaign, the current campaign policy prohibits political advertising, gambling, alcohol, tobacco, weapons, and financial products. These flags are campaign policy, not legal advice, and may change per city.

URLs

Links must resolve over http or https and are checked by a person before publication. We may refuse a link that redirects to content breaching these guidelines.

What happens if your artwork is refused

You are told why, by email, and either invited to submit a compliant replacement or refunded in full under the Refund Policy.
