General: Crank length/chain ring size and slowing down/skidding

Aplogies if this question has been covered elsewhere - but my question is whether crank length and and even your chain ring size/bcd will have a significant impact on your ability to slow down and skid stop on a fixed gear; or is it simply a matter of combining different gear ratios?

Thanks - yeah I figured that would be the case pretty much. I guess the crank length would have impact on cadence which would help a little slowing down.
