Most of the blades are roughly the same length (~30cm) as the P92 or P88. In my garage right now I have the McDavid, Barkov, and P38, as well as a retail PP88 (from Sherwood, which has a weird version of the P88). The Barkov is about 1cm longer than the PP88 and P38. Maybe .5cm longer than the McDavid. The Backstrom I had (which broke) was probably about as long as the Barkov. So just a touch longer than the retail P88.
