To be sure, but the point I was questioning was that A4 is too skinny for most use cases, that U.S. Letter was preferred in that regard. Adding 9% to the length of U.S. Letter doesn't seem to make it suddenly overly skinny.
Bad for origami though. Ditto with regard to A4. :-)

Preferred by whom? I've never encountered a use case where A4 was too skinny. And it certainly never stopped anyone from making paper airplanes from whole sheets at school. A4 folds neatly to sheets of the same ratio, which is its party trick and why the DL and C series of envelopes are a thing.
There are other paper sizes based around the A series that fit relate back to it as part of a geometric progression, which means stuff fits neatly together. For instance, the C and DL series, which are used for envelopes, with a C4 envelope being exactly the right size for a sheet of A4 paper.
