The Letter Final Khaph should have a roof which is no longer than 3 kulmusim. We should not lengthen its roof any further, nor make it shorter, as it could very possibly look like the Letter Reish or the Letter Vov. The leg of the Final Khaph should be a total of 5 1/2 kulmusim,when measuring from the top of the Chof to its tip. If it is any shorter, it could look like the Letter Reish. The top right corner of the Final Khaph should be rounded, as it is similar to it's cousin, the Khaph , which has a rounded top corner.
