A sketchbook is a book or pad with blank pages for sketching and is frequently used by artists for drawing or painting as a part of their creative process.

Sketchbooks come in a wide variety of shapes and sizes, with varied covers, and differing numbers of pages. Sketchbooks began as a way to provide a readily available supply of drawing paper in the convenient form of a book.

Sketchbooks made out of high quality paper, differentiated by weight (referring to density of the sheets) and tooth (also called grain), allow for a wide variety of techniques to be used, ranging from pencil drawings, to watercolor, to colored pencil, to pen and ink, and so on.
