change font size (but NOT home page or sidebar)

I’d like to change the font size of my blog posts and pages, but not the sidebar, menu, or homepage. So far, I found this custom CSS to add in Customizing>Additional CSS:

.body {
    font-size: 16px;
}

However, this CSS increases the font size of the sidebar and home page. For now, I modified it to increase the font size of just blog posts, like this:

.post {
    font-size: 16px;
}

Can you tell me how to modify it further so the page font size is also increased, but not the homepage, sidebar, or menu? Thanks!
