A symphony is typically much longer and more complex than an opera. An opera usually has three acts, while a symphony can have as many as four or five. The structure of the music in an opera tends to be more straightforward with clear themes and melodies that are repeated throughout each act, while a symphony often has more complex movements with multiple themes and variations. Additionally, an opera will generally have a smaller cast of characters compared to a symphony, which may involve dozens of singers and instrumentalists.
