From Classroom Projects to Science Fairs – Poster Boards in Every Size

How to Choose the Right Poster Board Size for School, Science Fairs & Presentations

Science Fairs – Poster Boards play a key role in creativity, since every project requires the right size and type. When it comes to creativity, not all projects are the same—and neither are poster boards. From small classroom assignments to large science fair displays, choosing the right trifold poster board size can make all the difference. Whether you need trifold poster board sizes for a big event, a white poster board 22×28 for classroom projects, or an extra-thick poster board for professional displays, there’s an option that fits your needs.

By knowing the size of poster board that works best for your project, you can save time and make your ideas stand out.

White & Trifold Boards for Every Project

If you’re looking for a simple, versatile solution, a poster board white option is always a winner. The smooth surface is perfect for markers, paints, and stickers. For projects that need more structure, a trifold poster board size offers a self-standing design that works beautifully at science fairs, business presentations, or classroom exhibits.

Why Choose Thick Poster Boards?

Sometimes regular poster boards aren’t enough. That’s where a thick poster board comes in—it’s sturdier, less likely to bend, and perfect for projects that need to travel or stay on display for a long time. Teachers often prefer thick boards for science fair projects, as they hold up well to glue, cut-outs, and layered decorations.

Tips for Making the Most of Your Poster Board

  • Plan your layout before gluing or taping anything down.
  • Use bright colors or layered paper (like neon project papers) to grab attention.
  • For trifolds, put the main idea in the center and supporting details on the sides.
  • Choose a size that matches your story—small boards for quick lessons, large boards for detailed presentations.
