Glossary
Concepts behind the numbers
The vocabulary writers and editors in San Diego run into when they review counts.
- Word countSource ↗
- The total number of word tokens in a piece of text, typically derived by splitting on whitespace and punctuation. Common in publishing, education, and SEO as a length metric.
- Character countSource ↗
- The total number of code points (or graphemes, in Unicode-aware tools) in a text. Platforms like SMS and Twitter enforce limits in characters, not words.
- UnicodeSource ↗
- The international standard that assigns a unique number to every character in every script. Modern text tools use Unicode so counts work consistently across languages and emoji.
- ReadabilitySource ↗
- How easy a text is to read, measured by formulas that combine sentence length, word length, and syllable counts. Higher readability typically means shorter sentences and simpler words.
- Flesch–Kincaid grade levelSource ↗
- A readability formula that maps text difficulty to a US school grade level using sentence length and syllables per word. A score of 8 means a typical 13-14 year-old should understand it.
- Intl.SegmenterSource ↗
- A JavaScript API that splits text into Unicode graphemes, words, and sentences using the same locale rules browsers use natively. Tools that use it count complex scripts correctly.
How we count, and when this page was checked
Word and character counts on this page use the browser's Unicode-aware Intl.Segmenter API, so figures match the underlying graphemes rather than guessing from byte length. Reading-time estimates default to 238 wpm (Brysbaert, 2019). Last editorial review: 2026-05-23.
