No, it's actually the exact same dimensions as the 2013 iPad Air. Maybe they're just not updated on the specs for this new model.

For a few years with my iPad Air I used a Logitech ultrathin magnetic clip-on keyboard cover. It worked quite well, battery was excellent on it. It functioned like a smart cover and had a spot for the iPad to sit in it snuggly while typing.
This was it:

I think they've also made several decent cases that included a built in keyboard as well.
