The Wave case will hold a total of 32". It is made to hold 31.5" and there is an extra quarter inch of compression with the foam rubber at the top and bottom. A 32 inch cue will fit in the case and be held snugly in both the horizontal and vertical position.
I should clarify that, anything that is a TOTAL of 32" will fit.
People say that their cue butt is 31" and what they ususally mean is that when the cue is assembled the butt section is 31 and the shaft is 31 making it a 62" cue. But in reality the butt is 31" PLUS the pin PLUS the joint protector.
So the wave case is made to hold a maximum of 32".
