A solid thesis statement is typically concise yet specific, usually functioning as a guiding claim for your paper. Most common guidance suggests one to two sentences, roughly 20–50 words, though the exact length depends on your assignment’s length and complexity. Here’s a practical way to think about it:

• Short essays (1–3 pages): Aim for a single, clear sentence.
• Medium-length essays (4–8 pages): One to two sentences that outline your main argument and the key points you’ll cover.
• Longer papers or theses (10+ pages): A slightly longer statement, often two to three sentences, that previews main points or sections and frames your position in more detail.

Key characteristics of an effective thesis statement:

• Takes a clear position or makes a specific claim that can be debated.
• Signals the main points or directions your paper will take.
• Is concise and precise, avoiding vague language and unnecessary qualifiers.
• Emerges as you refine your argument; you can start with a working thesis and tighten it as your research and writing progress.

If you’d like, share your assignment details (length, topic, and whether it’s argumentative, analytical, or evaluative), and a tailored recommended length and a sample thesis can be drafted.
