Result
How it works
- Paste multi-line text.
- Set your maximum characters per line.
- See each line's count with over-limit lines flagged.
The method
Each line is measured character by character against your limit, so you can catch overflow before it breaks a subtitle track, label, or fixed-width layout.
FAQ
What is this useful for?
Anywhere a line has a hard character limit — subtitles, product labels, fixed-width UI fields, or SMS-style messages — where a line running long gets cut off or wraps awkwardly.
Can I set a custom limit?
Yes — set any character limit per line and lines exceeding it are flagged.
Does it count spaces and punctuation?
Yes — every character on the line is counted, matching how most fixed-width displays measure length.
