media queries are too soon

Media (min-width: 1151px)

.content:not(:last-child) {

flex-basis: calc(100% - 340px);

max-width: calc(100% - 340px);

}

Don't you think that media query is too soon? I mean with 1150px, we still have many room for sidebar.

And it is the same with .mainMenu,.userPanel, and so on.
