What is the size limit of textbox field?

I am wondering if there is a one line text box connected to a question does that limit the number of characters that can be written.  If it's an essay type question does it need an expanded text box?

(it's not connected to a web page yet)

Hello MOLDALLAS,

Please note that every textbox has a "Max Size" attribute where you can set how many character you want to allow your users to key in. Please check the screenshot below:

If the value is "0", that means user can input any number of characters in textbox. Please note that our database limit for a single answer is 64kb. That means it can store 65535 single-byte characters.

For essay type question, you should use "Textarea" fields which will display multiple rows to user. Please check the screenshot below:

Hope this helps.

Do get back to us if you have any questions.

Thank you!
