[Plugin: Contact Form 7] contact form 7 resize text area

If you’re feeling adventurous, I would try the quick and easy way, using CSS. If you don’t know anything about CSS and stylesheets, and are not tech-savvy, I would avoid this. However….

Appearance… Editor. You should be editing style.css. Something like the following would give you an example. This specifically targets Contact Form 7’s text area, and you can adjust the numbers to taste:

.wpcf7 textarea  {
  height: 50px;
  width: 300px;
}

Cheers worked a treat

Actually, the regular way of specifying the text area works, too.

But, its handling of the number of columns is different than that of the handling of the length of text or email fields.

For example, a text or email field that is specified with a width of 28 roughly has the same width as a textarea specified with a width of 21.

If you work your way up from a smaller textarea to the proportions you ultimately want to see on the screen, you will see how it changes.
