Quick note: This tool is fixed to 150 words. If your school specifies "150 words or fewer," aim for 140 to be safe. Always confirm the limit in your school's application portal.

What does 150 words actually mean?
A 150-word supplement is not a condensed 250-word essay. It's not a trimmed-down version of a longer draft. It's a different format entirely: one that demands a single, focused idea supported by one concrete detail or example.
Colleges use 150-word prompts for specific questions: "Why do you want to attend our school?" "Tell us about your favorite class." "Describe a community you belong to." These prompts expect a complete, standalone answer. If your essay sounds like it's missing the introduction or conclusion, it is.
The key rule: 150 words = one paragraph, one thesis, one supporting example. No setup, no tangents, no asides. Every sentence works toward proving a single point.
One-paragraph structure for 150 words
Here's the formula that makes 150 words feel complete:
Hook sentence (1 sentence, ~15 words): The direct answer to the prompt. "I want to study environmental engineering at your school because..." or "My favorite class was organic chemistry because..." Make it clear and specific from sentence one.
Specific detail (2–3 sentences, ~50–80 words): One concrete example that proves your point. A project you completed, an experience you had, a skill you developed. Not a general statement, something only you could have written.
Reflection (1–2 sentences, ~30–40 words): The "so what?": why this detail matters to who you are or how you think. How does this example connect to your future goals or values?
This structure uses roughly 95–135 words and leaves 15–55 words of buffer for natural variation. You're not writing to hit exactly 150; you're writing until your idea is complete, then checking the meter.
Worked example: brainstorm to final paragraph
Here's how a real student moved from scattered ideas to a polished 150-word answer:
Starting brainstorm (bullet notes)
Environmental science interests
Took ecology class junior year
Did research on watershed restoration
Learned about invasive species
Want to work on conservation
Your school has great environmental program
Love the outdoors
Final 150-word paragraph
I'm drawn to environmental science because I want to bridge the gap between ecological research and real-world conservation. Last year, I led a watershed restoration project that involved removing invasive species and monitoring water quality in partnership with a local nonprofit. I discovered that the work I most cared about (testing soil samples, analyzing species data) required both field knowledge and quantitative rigor. Your environmental science program specifically integrates ecology and data analytics, which aligns with how I want to contribute to conservation. I'm particularly interested in your partnership with regional land trusts, as this hands-on approach to environmental stewardship is what drives my commitment to your program.
Notice: The final version is one paragraph, not five. It removes the filler ("I love the outdoors"), keeps the specific detail (watershed project, invasive species), and ties it to the future (bridge research and action). No introduction, no conclusion: just a complete idea.
How this tool counts: Words = text split on whitespace; hyphenated words count as one. Characters counted by Unicode grapheme. Sentences = text split on period, question mark, or exclamation. Paragraphs = split on blank lines. Reading time = words ÷ 200 rounded up.
Important: Different counters (this tool, Common App, Scoir, Coalition) may differ by 1–3 words due to handling of contractions, hyphenation, and line breaks. Leave a 5-word buffer below your target limit, especially on the actual platform.
One 150-word paragraph: hook (thesis), specific detail, reflection. Write from scratch: do not edit down from a longer draft.
Frequently asked questions
Can I fit two examples into 150 words?
No. Two examples would require two supporting paragraphs, and 150 words forces a choice. Pick the stronger, more specific example. A single vivid detail beats two generic ones. If you feel both are essential, your prompt may actually need a 250-word response: check your school's requirements.
Does this counter match Common App's counter exactly?
Not always. Common App, Scoir, Coalition, and this tool may each count 1–3 words differently due to how they handle contractions, hyphens, and line breaks. To be safe, aim for 140–145 words on this tool: that leaves a 5–10 word margin when you paste into the official portal.
My prompt says "150 words or fewer" vs. "about 150 words": does it matter?
Yes. "Or fewer" means it's a hard ceiling: you can go shorter if your idea is complete. "About 150" is softer and typically means 140–160 is all fine. "Approximately" also signals flexibility. Read your portal's help text or email admissions if you're unsure. When in doubt, 145 works everywhere.
How many drafts should I write at 150 words?
At least 2–3. Your first draft will likely be 120 words (too short and feels rushed) or 180+ words (trying to include too many ideas). Revision at 150 words is tighter than at 650: every word carries more weight. Write your first draft without a word limit, then cut to 150, then rewrite one more time for flow and voice. Quality matters more than speed at this length.
