A3 Poster Printing – Affordable, Versatile and Effective

The A3 poster (297 × 420 mm) is our most popular format – large enough to grab attention, yet compact enough to fit noticeboards, doors, or windows. It's a cost-effective and impactful tool for fast, clear messaging.

A3 posters are perfect for:

• Event promotion
• Campaign and sales announcements
• Schools, associations, and public spaces

Printed on high-quality paper right here in Helsinki – quickly, precisely, and according to your brand. With a print-ready PDF, your poster can be in production the same day.
