What is the most common surface used for canvas in painting?

The most common surface used for canvas in painting is linen, which is favored for several reasons. Linen fabric provides a strong, durable, and smooth surface that can hold paint well, making it an excellent choice for artists. Its natural fibers are less prone to warping over time compared to other materials. Additionally, the texture of linen can enhance the final appearance of the artwork; it allows for a range of techniques from fine detail to broader strokes. Many professional artists prefer linen for its longevity and ability to support various painting mediums, such as oil and acrylic paints.
