I would think that in a 737-900 like most reasonably large aircraft, it might depend on your weight, the wind conditions, runway conditions, elevation, slope and perhaps a few other things. What is reasonable one day might be short the next.
We used to land on 5000 foot gravel runways in the -200 and Alaska Airlines apparently did 3,900 feet in Dutch Harbour. That is short.
