Jackets and coats differ primarily in length, weight, and purpose. Jackets are shorter (hip-length or above), lighter, and designed for moderate weather or style-driven layering. Coats are longer (knee-length or below), heavier, and built for insulation against harsh cold. Materials like wool or down dominate coats, while jackets use lighter fabrics like denim or nylon.
