Formula Field Maxlength

I am constructing a formula field of type 'Text'. The formula concatenates the value of about ten fields. I am not sure, if there is a limit on the length of a formula field ? Please advice

From the help:



3,900 character limit per custom formula field.

5,000 character limit in the SQL query generated per formula field.

32,000 character limit on the SQL statement for entire object, including all standard and custom fields and all formula fields.


Hope that helps,
