Does a ridge vent have to span the entire ridge?

I only ordered enough ridgevent for the house. I forgot to include the garage. If I take a 4' from each end, I'll have enough. Is this acceptable?

my house has it from end to end....while my neighbors house does not (its set back about 5 feet from each end.) dont know if one way is more right than the other, just have seen it both ways.

I suspect the right answer includes some calculations regarding air flow.

Yes it is perfectly acceptable. Most roofers will hold the ridge vent back from the ends of the ridge just so the roof is easier to seal at the ends. I have a hip roof on one end of my home and a straight gable end on the other. The gable end actually has a 2-4 foot soffit that I thought should be vented as well, though the roofers say it isn't needed since there is no heat and humidity built up in the overhanging soffit. I did it anyway just to maintain a somewhat symmetrical appearance on the roof.
