In motion picture animation, a model sheet is a document used to help standardize the appearance, poses, and gestures of an animated character. Model sheets are required when large numbers of editors are involved in the producation of an animated film to help maintain continuity in characters from scene to scene, as one animator may only do one shot out of the several hundred that are required to complete an animated feature film.

Model sheets have also been used in the past to maintain graphic continuity over the years for long lasting cartoon productions of short or very short features (around seven minutes or less) such as the ones produced in the Looney Tunes or Merrie Melodies series for several decades.
