negitive battery cable length

[RichardOdie]

Yesterday i went to my local autoparts store and tried to buy a negitive battery cable and they asked me for a length , I tried to look but it runs down and towards the rear of the truck, can anybody give me the correct length of this cable. I own a 1991 explorer XLT 4.0 liter

what i heard was the shorter the better. you could make a new ground. i know for sure this is true for stereo equipment.
