Today I was asked a question. What is the maximum number of characters for a text field in Dynamics CRM/Power Platform? I admit I was stumped and it wasn't something I knew, although I probably should.
A Single Line of Text field can contain up to 4,000 characters
A Multiple Lines of Text field can contain up to 1,048,576 characters.
For all the details on each field type in Dynamics CRM/Power Platform read the below Microsoft Docs article.
