One of my clients asked me this question. This may seem like a dumb question, but it’s worth discussing so as to help writers who are new to the game. Short answer: The god of fiction has not prescribed the length of a scene. A scene should be as long as it needs to be in order to accomplish its goal. Each scene should be planned before the writing begins. The plan must begin with establishing its purpose. The scene should incorporate at least one of these purposes:
• Move the main plot line ahead
• Present necessary information
• Introduce or develop characters
• Create atmosphere or develop setting
• Introduce or worsen a problem
• Solve a problem
• Set up a later scene.
In addition, you must answer the following questions before you begin writing a scene:
• Who will be the viewpoint character?
• What other characters will be in this scene?
• Where will this scene take place?
• When will it take place?
• What is the primary action that will occur in the scene?
• What will generate conflict?
When you have determined the purpose of the scene, answered the questions above, and fulfilled its purpose, the scene will find its natural length.
