I have a simple feedback form (see screenshot) on each page on a site. The user has to select whether the page was helpful or not (radio buttons yes/no) and there is also a text area input where the user can add extra information about how we could improve the page.
Would you recommend I have a character limit on this field (i've seen it done on other sites that are similar to mine) and if so, what would be a reasonable character limit to set?
N.b. I can't find a similar question about character limits on feedback/comment fields so please edit if there is a similar question already posted (I'm surprised I can't find one).
