If I am using it for temporary projects, a standard thickness works fine. For anything more long-lasting, I usually choose a sturdier option.
Surface Finish and Print Compatibility
I consider the surface finish before buying. If I plan to mount photos, print graphics, or attach paper, I want a smooth surface that looks neat and clean. I also make sure the board is compatible with adhesives, tape, and pins if I need to add extra materials. A white, matte finish is often my go-to because it gives a simple and polished look.
Weight and Ease of Handling
One of the reasons I like foam board is its lightweight feel. I can move it around easily, which helps when I am setting up displays or working on large projects. Even though it is light, I still want it to feel solid enough to stay flat and presentable.
