4,000 characters ≈ 1,000–2,000 tokens
Token count depends heavily on content type
| Content type | Chars / token | Estimated tokens |
|---|---|---|
| Prose / English | 4.0 | 1,000 |
| JSON | 3.5 | 1,143 |
| Code | 3.3 | 1,212 |
| Non-Latin / other | 2.0 | 2,000 |
The same number of characters becomes a different number of tokens depending on whether it's prose, code, JSON or non-Latin text. Enter a character count to compare across content types.
How this is calculated
This calculator uses the tokens formulas described in our methodology. All figures are estimates for planning; verify current pricing with each provider before relying on them.

Frequently asked questions
Why does code tokenize differently?+
Code has more symbols and short tokens, so it packs slightly fewer characters per token than prose.
Which ratio should I use?+
About 4 chars/token for English prose, ~3.3 for code, ~3.5 for JSON. Non-Latin scripts are far denser.
