I interpreted Terry's question as "would", not "should". I didn't mean to imply they had to be exactly equal. Mine aren't, but for practical purposes to measure how much wire you need to buy, it would be prudent to do so. Why wouldn't you anyway? I can't see any reason why you would take a different route for each wire. You don't have to buy paired wire either. I bought my copper wire in 500 ft rolls at Home Depot and ran each hot and common separate but through the same benchwork holes together.
