Someone asked why I make portrait-oriented cards with folds on the top rather than the side. Honestly, I hadn't really thought about it. No good reason, I guess, except that I find it easier to photograph them that way and they seem to stand up better for display.
Here's a portrait-oriented card with a top fold. See how nicely it stands for its picture?
Now, here's a landscape-oriented picture with a top fold. It also stands nicely.
As far as I know, there are no rules about folds. I certainly don't judge folds. In fact, you can fold any way you want and as long as you're not hurting anyone, it's okay in my book.
Orientation, on the other hand, does have certain design rules, but those pertain to balance and harmonious composition for each individual card. Neither orientation is right or wrong in and of itself; orientation is a case-by-case issue, as these two cards show.
And by the way, I don't judge orientation, either.
