Dwarves, also known as dwarfs in some adaptations, have been a staple in fantasy literature for decades. In works such as J.R.R. Tolkien's "The Hobbit" and "The Lord of the Rings," dwarves are depicted as a sturdy, hardworking, and enduring race. They are known for their mining skills, craftsmanship, and deep sense of family and honor. Tolkien's portrayal has set a standard for subsequent fantasy literature, often showing dwarves as resilient and proud, living in mountainous regions and excelling in metalwork and gem cutting.

In fantasy films, the portrayal of dwarves often mirrors their literary counterparts but is additionally influenced by visual and cinematic elements. Movies like Peter Jackson's "The Lord of the Rings" and "The Hobbit" trilogies have brought these characters to life with rich detail and robust performances. The dwarves in these films are characterized by their strong physicality, often played by actors under layers of prosthetics and costumes, enhancing the perception of their strength and resilience. These adaptations also emphasize the dwarves' struggles and triumphs, offering a cinematic version of their complex and often tragic history and culture.
