stripe size 65 Barracuda

I would like to know the proper size of the stripes. I believe they are 6inch, with a 1inch gap and a 1inch stripe on each side. This would make a total of 10 inches wide. Does this sound correct? I have seen one locally that has a 10inch stripe with the 2 1 inch stripes as well. The second would be 14 inches wide.
Thanks for any thoughts
