My answer is yes. To all of those! I have a 6 X 24 for longer cuts but a 6 X 12 that I use the most. Also a 6" square, an 8" and a 12". I love the 12 (actually 12 1/2") for when I'm squaring up a larger finished project that I want a good corner. It would be cumbersome on a smaller project and that's when the smaller ones come into play. I have a few specialty rulers but they are not used often such as these others that I would consider to be my basics.
