For a 1 ½-inc pipe the vent should be 42 inches away at the most while a 2-inch pipe must have a maximum distance of 5 feet. If you have 1 ¼-inch pipe, the horizontal distance of the vent should not be more than 30 inches. As for the maximum distance between your trap and your vents, that would depend on the actual diameter of the plumbing pipe. So now you see how these plumbing elements are interrelated.

Keep this clearance in mind and you should have no problem with horizontally installed vent pipes. What is a spill line? This is the level where the water starts to overflow from the rim of the sink, toilet, or tub. There is no problem with running your vent pipes horizontally as long as you remember that there should be a minimum clearance of 6 inches above the spill line.
