They tend to change the height on the boxes back and forth every year, so most shops just keep it at 1.9. This works for a lot of other plans so it’s usually worth it to just keep them that size. But it’s completely up to you and how you want to size them.
I know that this is usually a problem between the colorful and the neutral. The neutral isn’t 1.9 because they removed the headers, but the colorful some years will be 1.9 and sometimes its not because they change the size of the headers. Lol.
