I made these boards wide based on a blog post by the author of the article/video I'm following to build this tool chest (to allow for common mistakes and their correction without ending up undersized). Turns out there is about 4" of too much overall length for the back wall of the chest. That is a bit over half the width of these four 7-1/4" tongue and groove boards.
I still have to make the 30° bevel on the top board, and I might mess that up, I want to make sure I get that right before I trim the others. But assuming I get it right on the first try, I need to take out 4" from somewhere. Easiest would be the bottom board, but that leaves it pretty skinny at about 3-1/2", I wonder if that'll be too weak? Even more so the top board will have the hinges attached. If it is too skinny I wonder if it'll hold up to the stresses from the lid. Or do I split the difference and take off 2" from the bottom and the top?
