That's a fair point - just because the portrait orientation works for most sites doesn't mean it works for all sites.
So have I got a tip for you, friend. In case your wife hasn't found the right paper for her project yet, the best thing I can think of is to get a giant 11"x17" pad of Edward Tufte's grid paper. Scroll to the bottom of his shop page here:
Not only is it large and easily usable in landscape mode, it uses what he calls a "ghost grid", where the grid is printed with a barely noticeable light ink so that it's visually less dominant and it fades into the background compared to the ink drawings you make on top of it.
I used nothing but Tufte's paper for years and was deliriously happy with it. It was so big that I could use it for all kinds of stuff, whether site flows or detailed UIs, whatever. The only reason I switched away is that not every project needed that much real estate and it's not the easiest thing to carry around. It's like having to tote around a whiteboard.
If she wants something smaller and more portable, there's the dot grid book by Behance:
