How this tool works
Text size uses grapheme clusters, Unicode code points, and UTF-8 bytes. X weighting uses twitter-text, including URL and emoji rules. SMS reports GSM-7 or UCS-2 and multipart capacity. Meta title and description budgets are editorial guidelines, not pixel measurements.
Input and output stay in the current page. Refreshing or closing the page clears them. For very large inputs, use Run to start processing; a task that takes too long is stopped so you can change the input.
Frequently asked questions
Why does one emoji change the SMS encoding?
A character outside GSM-7 switches the whole message to UCS-2: 70 units for one segment, or 67 units per multipart segment.
Does every X character count equally?
No. The counter applies weighted text rules; recognized URLs count as 23 points and many emoji or non-Latin characters count as two.
