Pen Art is a versatile and expressive art form that uses pens—ranging from ballpoint, gel, and ink pens to fine liners and technical drawing tools—to create detailed illustrations, sketches, and intricate linework. Known for its precision and control, Pen Art thrives on contrasts, textures, and depth, often using techniques like hatching, cross-hatching, stippling, and contour lines.

The style varies widely—from hyper-realistic portraits and surreal compositions to abstract doodles and architectural studies. Other forms include Zentangle, Botanical tangle, Freeform, Scribbling, Stippling, Doodling, Zendoodleing, Ink and wash, Calligraphy. Artists often work in black and white, but colored pens are also used to introduce vibrancy and layered emotion.
