I didn’t know that kind of paper even existed, so I can’t help you much on that. However, I completely agree, it looks like perfectly adapted for working on coding issues (or for other things, in fact
).
However, after reading the Wikipedia page on “ruled paper”, which says …
Gregg ruled paper has ruling specialized for stenography. It has 11/32 in (8.7 mm) spacing between ruling lines, with a single margin drawn down the center of the page.
…, it may exist, as no size is specified for the sheet itself. (
) Sorry.
