Set max character limit in Lists multi-line column

[laser132217]

Hello, 

I have a multi-line column in a Microsoft Lists list and users are putting too much text in it. I would like to set a maximum character limit to prevent this (for example 500 characters). Can anybody advise how I would do this? 

Thanks

@laser132217 the only out-of-the-box way to do this that I know of is to:

• create the column as a single line of text column
• set the validation settings to =LEN(yourcolumn)<500
• change the column type to multiple lines of text

The validation will still be applied even though it is now a multiple lines of text column.

Hi Rob,
Thank you for your help. Can I clarify whether the validation is a column validation or a list validation?
Thanks

@laser132217 you do this in list settings -> validation settings
