The short version
Word count counts whole words. Character count counts every individual letter, number, space, and punctuation mark. A sentence with a few long words can hit a character limit well before it hits a word limit — and the reverse is just as true.
Why the difference matters
Most writing advice talks about word count, but a lot of real-world limits — social posts, text messages, meta descriptions, form fields — are actually measured in characters. Writing to the wrong number means your text can get cut off, rejected, or flagged as too long, even though it "felt" short enough.
Common character limits
| Platform / field | Limit |
|---|---|
| X (Twitter) post | 280 characters |
| SMS text message (1 segment) | 160 characters |
| Google meta description | ~155–160 characters shown |
| Google title tag | ~55–60 characters shown |
| Instagram bio | 150 characters |
These are approximate and platforms change them over time — always check the current limit if it's for something important, like an ad or a listing.
Common word limits
- College application essays often cap at 650 words (the Common App essay, for example).
- Academic abstracts are typically 150–300 words.
- Blog posts aimed at ranking well are often 1,000+ words, though this depends heavily on the topic — see our guide on how many words a blog post should be.
How many characters is the average word?
In English, the average word is about 4.7 characters long, or close to 6 characters once you include the space that follows it. This is only a rough average: "a" is 1 character and "characteristically" is 18, so word count and character count can diverge a lot depending on your vocabulary.
Do spaces and punctuation count?
Almost always, yes, for character limits like X/Twitter and SMS. If you're unsure for a specific form or platform, it's safer to check live rather than assume — paste your text into a counter and compare it against the stated limit.
Check both at once
The WordlyCounter word counter shows word count and character count side by side as you type, so you can see instantly which limit — if either — you're actually approaching.
Frequently asked questions
What's the difference between character count and word count?
Word count is the number of words in a text. Character count is the number of individual letters, numbers, spaces and punctuation marks. A single long word can use up a character limit faster than several short words.
How many characters is the average word?
In English, the average word is about 4.7 characters, or close to 6 characters including the space after it. This is only an average — individual words vary a lot.
Do spaces count as characters?
It depends on the platform. Most character limits, including X/Twitter and SMS, count spaces as characters. Always check the specific platform if it matters.
