In Gravity Forms there is the option to count characters. But maybe you want to limit the amount of Words typed in a Single Line Text, Paragraph Text and Post Body fields. You can do this with the Gravity Perks Plugin Word Count. With this plugin it’s possible to set a minimum number of Words and a maximum number of Words in a text field in Gravity Forms. This way you have much more control over what people type in your form.
