Twitter / X字元計數工具

為Twitter/X貼文統計字元數。由於Twitter的t.co縮短機制，URL會自動計為23個字元。

0/280 字元

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對每則貼文設有280個字元的限制。無論URL實際長度如何，它始終計為23個字元，因為Twitter會透過t.co自動對其進行封裝。表情符號通常計為2個字元。本工具會模擬這一計數方式，幫助你將內容控制在限制範圍之內。

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.
