More control over form fields when creating a new form

I am creating a form to collect information for new employee hires to order an onboarding kit. As part of this form, I am including a textarea for their address. The default is set to 2 rows, which is okay, I guess. However, I would like to set it to 5, for aesthetic reasons.

However, these is no way to control how many rows or columns are set by default. It would be great to be able to have that control.
