[Plugin: Contact Form 7] Contact 7 Sidebar Input text length

I am creating a new site and want to use Contact 7 in a sidebar. I am finding that the input text boxes are outside the range of my sidebar area. Is there anyway to make these input text boxes smaller so i can have them fit the sidebar?

The only way i can see, so far, to make this work is by increasing the width of my sidebar…something i do not want to do.

Here is a link to my site so you can see what i am talking about.
