FAQ
School poster size questions
Which poster sizes do schools use most for hallways, classrooms and flyers?
24×36 inches is the most common school poster size. 18×24 suits classroom walls and anchor charts, and 11×17 suits flyers and bulletin board notices.
What size is a classroom bulletin board?
Most classroom bulletin boards are about 7 to 8 feet wide and 3 to 4 feet tall. Always measure your own board before printing.
How big should text be on a school poster?
Plan about 1 inch of letter height for every 10 feet of viewing distance. A title read from 20 feet away needs letters about 2 inches tall, roughly 144 pt.
What resolution should images be for a poster?
Use 100 to 150 ppi at the final printed size. A 24×36 poster needs an image of about 2400×3600 to 3600×5400 pixels.
How long can a school poster maker print a banner?
Roll-fed poster makers are limited by roll width, not length, so a 24 or 36 inch machine can print banners as long as the roll allows.
