If you mean the character limit on Binance Square (formerly Binance Feed posts):

Posts usually allow up to around 1,000–2,000 characters (this can vary slightly depending on updates and formatting like hashtags or links).

Comments tend to have a shorter limit (a few hundred characters).

If you meant something else by “Binance square character” (like a username format, symbol, or a specific post requirement), tell me and I’ll clarify 👍
