Definition

A logline is a one or two-sentence summary of a screenplay or book that captures the essence of the story. It typically includes the protagonist, their goal, and the obstacle they must overcome. On the other hand, a premise is a brief description of the central idea or concept of a story. It provides the foundation for the plot and characters but does not delve into specific details.

Length

Loglines are usually shorter than premises, consisting of only one or two sentences. This brevity is intentional, as loglines are meant to be concise and to the point. Premises, on the other hand, can be longer and more detailed, as they serve as the starting point for developing a full story. They may include more information about the setting, characters, and conflict.

Focus

Loglines focus on the core elements of a story, such as the protagonist, their goal, and the obstacle they face. They are designed to grab the attention of potential readers or viewers and give them a sense of what to expect. Premises, on the other hand, provide a broader overview of the story's central idea and themes. They set the stage for the development of characters, plot, and conflict.

Use in Pitching

Loglines are often used in pitching a screenplay or book to agents, producers, or publishers. They are a quick and effective way to communicate the essence of a story and generate interest. Premises, on the other hand, are more commonly used in the early stages of development, when outlining the basic concept of a story. They help writers and creators clarify their ideas before diving into the details.

Clarity

Loglines are typically more straightforward and direct than premises. They aim to convey the central conflict and stakes of a story in a clear and concise manner. Premises, on the other hand, may be more open-ended and exploratory, allowing for a broader interpretation of the story's themes and ideas.

Examples

Here are examples of a logline and a premise for the same story:

• Logline: A young wizard must defeat an evil sorcerer to save the kingdom.
• Premise: In a magical land, a young wizard discovers his true powers and embarks on a quest to defeat an evil sorcerer who threatens to destroy the kingdom.

Conclusion

While loglines and premises both serve as tools for summarizing and conceptualizing a story, they have distinct attributes that set them apart. Loglines are concise and focused on the core elements of a story, while premises provide a broader overview of the central idea and themes. Understanding the differences between the two can help writers and creators effectively communicate their ideas and develop compelling narratives.
