Almost everything you write lives inside a limit: the application that cuts you off at 650 words, the tweet box counting down from 280 characters, the hiring manager who stops reading page two. Knowing the target before you write saves the painful surgery of cutting a 900-word essay down to size at midnight. This is the reference guide — the numbers that actually matter, platform by platform — plus how to hit any target cleanly. Keep Utilo's free word counter open in another tab while you write; it counts words, characters, sentences, and reading time live as you type.
College essays and academic writing
The big one: the Common Application personal statement caps at 650 words (minimum 250). Supplemental essays are usually 150–400 words each. Go over and the portal literally won't let you submit; go far under and you look unserious — aim to land within 10% of the max.
For class assignments, the professor's number is law, but typical bands are: short response 250–500 words, standard essay 750–1,000 words, research paper 1,500–2,500 words. Graduate theses start around 10,000. When no limit is given, match the depth of the question — a prompt asking you to "analyze" wants more than one asking you to "summarize."
Resumes and cover letters
Resumes aren't judged by word count but by pages: one page for students and early-career professionals (roughly 400–600 words), two pages max once you have a decade of experience. Recruiters spend about seven seconds on first scan — density is the enemy. Every line must earn its place.
Cover letters: 250–400 words, three to four short paragraphs. Nobody has ever been hired because their cover letter was long. Say why this role, why you, and stop.
Social media character limits
- X (Twitter): 280 characters per post. Threads beat long singles.
- LinkedIn: 3,000 characters per post, but only the first ~210 show before "see more" — front-load the hook. Articles can run much longer.
- Instagram: 2,200 characters per caption; hashtags don't need to eat that budget anymore.
- Facebook: effectively unlimited (63,206 characters), but engagement craters past ~250.
- TikTok: 4,000 characters for descriptions; 2,200 for photo-mode captions.
- YouTube: 5,000 characters for descriptions; titles cap at 100 (keep them under 60 so they don't truncate).
- Reddit: 40,000 characters per post, 10,000 per comment — generous, but brevity still wins upvotes.
Remember: on nearly every platform, spaces count as characters. A counter that shows both with-spaces and without-spaces totals — like Utilo's word counter — keeps you from getting bitten at the boundary.
Blog posts and SEO content
There's no magic number, but data consistently shows that content ranking on page one of Google tends to run 1,000–2,500 words. The mechanism isn't the count itself — it's that thorough coverage earns links, keeps readers on the page, and answers the follow-up questions that short posts leave hanging.
That said, length without substance is worse than brevity. A 600-word post that fully answers a narrow question ("how many ounces in a cup?") will beat a padded 2,000-word ramble every time. Match length to the query: quick answers get quick posts, complex guides get long ones. Our own article-length guide digs deeper into matching length to intent.
Email, meta descriptions, and the small stuff
- Email subject lines: under 50 characters to avoid truncation on mobile; under 40 is even safer.
- Meta descriptions: ~150–160 characters. Google truncates beyond that — put the key message first.
- Meta titles: ~50–60 characters before truncation in search results.
- SMS: 160 characters per segment; longer messages get split (and sometimes reordered).
- Google Ads headlines: 30 characters each — every character is expensive.
How to hit a target without padding (or butchering)
Too long? Cut adverbs and throat-clearing first ("in order to" → "to", "due to the fact that" → "because"). Then look for repeated points wearing different clothes — say it once, well. Kill your darlings: that clever paragraph that doesn't serve the point is costing you words and readers.
Too short? Don't pad — deepen. Add the example you skipped, answer the obvious objection, include the "how" behind the "what." A concrete detail is worth ten filler sentences. If you've genuinely said everything, consider whether the target was a ceiling, not a floor — coming in under is fine when the content is complete.
The fastest workflow: draft freely, then paste into a live counter and edit to the target. Utilo's word counter is free, private, and runs entirely in your browser — and the Utilo homepage has the rest of the toolkit when your writing needs images, QR codes, or passwords too.
Frequently asked questions
How many words should a college essay be?
The Common App personal statement caps at 650 words (minimum 250). Supplemental essays usually run 150–400 words. Always follow the stated limit — portals enforce maximums strictly.
How many words fit on one resume page?
Roughly 400–600 words with standard formatting. But resumes are judged by pages, not words: one page early-career, two pages max for experienced professionals.
What is the ideal blog post length for SEO?
Top-ranking posts typically run 1,000–2,500 words, but depth matters more than count. A complete 600-word answer beats a padded 2,000-word post for narrow queries.
Do spaces count in character limits?
On almost all platforms — X, SMS, form fields — yes, spaces count. Use a counter showing both with-spaces and without-spaces totals to stay safe at boundaries.
