When to use which case
- camelCase - variables and functions in JavaScript, Java, Swift.
- PascalCase - classes and components (React, C#).
- snake_case - Python, Ruby, database columns.
- kebab-case - URLs, CSS classes and file names.
- CONSTANT_CASE - constants and environment variables.
How the counts work
Words are runs of non-space characters. Sentences are counted by their ending punctuation. Reading time assumes about 238 words per minute for silent reading and 150 for speaking aloud - useful for blog posts, speeches and video scripts. Bytes show the UTF-8 size, which matters for fields with a byte limit (emoji and accented letters take more than one byte).
Writing limits at a glance
A typical tweet-style post is a few hundred characters; a meta description for search results is best around 150-160; a one-page document is roughly 500 words. Paste your draft and check.
Frequently asked questions
Is my text saved?
Only in your own browser (local storage) so you do not lose it if you refresh. It is never sent anywhere. Clear it by emptying the box.
How does Title Case handle small words?
It capitalises every word - fine for most uses; style guides differ about words like "of" and "the".
Why do characters and bytes differ?
Characters like é or 😀 use several bytes in UTF-8.
