What counts as a word?
Different tools count differently, which is why numbers rarely match. This tool counts whitespace-separated tokens — the most common convention. A hyphenated compound like state-of-the-art counts as one word, while don't counts as one word as well.
Why character limits matter
Different platforms impose different caps, and going over means your content gets truncated:
| Platform | Limit |
|---|---|
| X / Twitter post | 280 characters |
| Meta title | ~60 characters |
| Meta description | ~155 characters |
| Instagram caption | 2,200 characters |
| LinkedIn post | 3,000 characters |
| SMS (single) | 160 characters |
Reading and speaking time
Estimates use 200 words per minute for reading and 130 words per minute for speaking. Speaking is slower because it includes pauses, emphasis and pronunciation. For presentations, budget 1–2 minutes per slide.
Keyword density
The keyword list shows which words appear most often after removing common English stopwords. It is useful for checking that a blog post actually focuses on its topic, and for spotting repetition while editing.
