What is the difference between poster board and illustration board?

Answer 1

Poster board is a thicker, more rigid paper typically used for making signs, presentations, and crafts, known for its smooth surface and vibrant color options. In contrast, illustration board is a higher-quality, heavyweight board specifically designed for artists; it often features a textured surface that accommodates various mediums like paint, ink, and pencil. While both are durable, illustration board is preferred for detailed artwork due to its superior ability to hold and blend materials.
