Hi @doywil,
I’m going to answer your questions one by one as follows ??
Is it possible to change the width of the recaptcha field ?
This implementation may be possible with custom development, however, we aren’t able to help with custom code requests like this, so if you need assistance, you may want to look into one of these services:

Note that we don’t currently have the bandwidth to do any custom dev work ourselves, as we’re focused fully on improving our core products, but several users have had success hiring freelancers as needed, so if customizations are very important to you and you’re unable to implement it yourself, you might want to consider going that route.
When I am using the simple style, the recaptcha field width is greater than the width of the form.
That’s a bit odd, so I’d suggest checking whether it’s a theme-related conflict before trying more customisations and CSS changes.
Try to temporarily switch your theme to Twenty Sixteen and see if the problem persists. You’re welcome to use the Theme Switcha plugin to do that:

This plugin lets you change themes without it affecting the way users see your site.

how do I change the background colour of the form? It’s grey, I’d like to change it to white to blend with the site background colour.
You can customize the look of every element on your site thanks to CSS. You can add that CSS to your theme stylesheet, or to your custom CSS editor available under Appearance > Customize > Additional CSS in your dashboard.
If you are not familiar with CSS, I would recommend this tutorial:

Hope that answers your questions! Let me know how you get on and if you need more help from our end ??
