How Many Characters Is 1,000 Words? A Practical Guide to TTS Limits
1,000 words in English is roughly 5,500-6,000 characters, including spaces. The average English word is about 4.7 letters long; add one space per word and round for punctuation, and you land in that range. It varies with your actual vocabulary — technical writing with longer words runs higher, simple text runs lower.
Why TTS tools measure in characters, not words
A "word" isn't a consistent unit — "cat" and "responsibility" are both one word but very different amounts of audio to generate. Characters are the actual input the underlying model processes, so limits and pricing based on characters are more predictable than limits based on word count would be.
Quick reference table
| Word count | Approx. characters |
|---|---|
| 100 words | ~550-600 |
| 500 words | ~2,750-3,000 |
| 1,000 words | ~5,500-6,000 |
| 2,000 words | ~11,000-12,000 |
What this means for your request limits
On HixCodeTTSv1, free text-to-speech requests go up to 1200 characters — roughly 218 words — per request, and paid requests go up to 10,000 characters, roughly 1,818 words. If your script runs longer than your limit, split it at natural breaks — paragraph or scene boundaries — rather than mid-sentence, so each generated clip still sounds complete on its own.
