Those are the ones plus my 61/2 square.

I definitely use the 6x24 the most because I usually cut strips. Rather than folding the center fold back up to the selvage to cut 4 layers, I fold end to end of the fabric piece. I am still cutting 4 layers at a time, but it is easier to line up the folds and the ruler to get straight strips. And it is actually cutting 2 strips at a time.

After 30 years of quilting I finally got a 12x12. It does make squaring up easier.

I have a ruler that I brought in 1999. It is a 6 1/2 by 24 and I love it. The numbers and lines are starting to disappear but I plan on using it as long as I can. I have a smaller one but only use it for trimming. I also have a 8 1/2 by 24 and then there is the tons of other rulers that I had to buy for special quilting classes. Too many!

The ruler I reach for more than any others is 6.5x12". Second is my shape cutter.

Ive collected many rulers but only use a few.
The basic 6 x 12 and 24. 12 and 16 square up rulers.
triangle square up by Quilt In A Day and all the flying geese rulers.
Several square rulers and fussy cuts.
I have the shape cut but dont use it because Im afraid of folding messes.
Lots of specialty rulers that I have used once.

I use my 6 X 24 Omnigrid for cutting strips and my 6 X 12 Omnigrid for crosscutting the most.

My 6 1/2 X 13 is the one I use the most.
Also my 3 1/2 X 9 1/2 is the one I use the most next to my machine. If I am cutting out a quilt I use my Quilt Cut
