I just make grosgrain cheer bows, havent ventured into the mystique and glitz bows. It really just depends on who you are making the bows for and what they like long tails or short tails and what material the bow is made of.
When I use 2.25" ribbon I use around 27-30" depending on how long the tails will be.
bow sizes range from 5"-7" across, tails ranging from 4"-7" long with 5.5" being pretty standard.
My Texas size bow is made with 3 inch ribbon bow measures 7" across with 6.5" tails (measuring from center knot to end of the tails)
I'll attached a pic of one
