Twitter / X字符计数工具

为Twitter/X帖子统计字符数。由于Twitter的t.co缩短机制，URL会自动计为23个字符。

0/280 字符

如何使用本工具

1
Type or paste your draft into the text box.
2
Read the live counter below it, shown as used/280.
3
If you go over, the box turns red and shows how many characters you are over by.
4
Trim your text until the counter is at or under 280, then copy it into Twitter/X.

Twitter/X对每条帖子设有280个字符的限制。无论URL实际长度如何，它始终计为23个字符，因为Twitter会通过t.co自动对其进行封装。表情符号通常计为2个字符。本工具会模拟这一计数方式，帮助你将内容控制在限制范围之内。

Checking a single tweet fits in 280 before posting, without opening the compose box.
Drafting a tweet in a notes app or spreadsheet and validating the length offline.
Confirming a post stays under the limit after pasting in a long t.co-style link.
Writing thread segments and trimming each one to a clean 280-character chunk.
Teaching or demoing how t.co link shortening affects the character budget.
Quickly seeing the exact overflow count so you know how much to cut from copy.
