    What is the size limit of textbox field?

    Asked by MOLDALLAS on September 18, 2016 at 10:45 PM

    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?

    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!
