A broadside poster is a large-format print designed to command attention on walls, fences, and notice boards. Used for events, causes, and community messaging, it combines bold visuals with concise text to communicate a message at a glance.
Creating an effective broadside poster involves planning size, message hierarchy, and print-ready details so the final output looks professional and readable from a distance.
| Poster Goal | Key Design Choices | Practical Specs | Delivery Method |
|---|---|---|---|
| Event Promotion | Large date, venue, headline | 24" x 36", 100 lb cover stock | Street distribution, venue walls |
| Advocacy Announcement | Strong headline, simple icon, clear ask | 18" x 24", matte finish | Community centers, cafes |
| Artistic Display | Minimal text, impactful image | 20" x 30", premium paper | Galleries, framed indoor use |
| Call to Action | Contact info, QR code, deadline | 24" x 36", weather-resistant | Public spaces, rallies |
Choosing Dimensions and Paper for a Broadside Poster
The classic broadside format usually prints at 24" x 36", but smaller sizes like 18" x 24" work well in tighter spaces. Heavier cover stock, at 100 lb or more, prevents curl and withstands outdoor display. For high-traffic areas, choose a weather-resistant coating or laminate to protect ink from rain and sun.
Establishing Visual Hierarchy and Messaging
Create a clear hierarchy with a bold headline, supporting subheadline, and a simple body that states the who, what, when, and where. Limit your color palette to two or three vivid tones so the poster remains legible at a distance. Use strong contrast between text and background to ensure readability even from a few feet away.
Design Layout and Typography Considerations
Place the most critical information in the top third where eyes naturally land, and use large sans serif type for headlines that stay clear from a distance. Keep body text short, using bullet points or short lines to break up content. Ensure fine details and thin strokes are large enough to reproduce cleanly on press.
Production, File Prep, and Print Setup
Export your file at 300 DPI in CMYK color mode, with a 0.125" bleed and safety margins for trimming. Convert text to paths or outline key typography to avoid font issues, and flatten layers where required by your printer. Specify paper type, coating, and finishing options such as grommets or hanging tabs so the shop can produce an accurate proof.
