How to measure and cut chain I am currently building a road bike. I measured the chain using the largest ring and largest cog method, I counted two extra links and cut the chain using a chain tool.

Both ends of the chain now have narrow ends. I want to use a power link, I understand that if I use the power link to join the ends, the chain will be one link longer than necessary.

How can I remedy the situation?

Appreciate any help.
You put the powerlink on the chain and move on with your life. Provided the chain is not insanely too long, it's going to work fine unless you're on the boundary of what your shift system can handle in capacity (which almost nobody is) and you're abusive at this boundary. 

Note that the article clearly states how to size when accounting with a master link:


  MASTER LINK NOTE: If the bike chain uses a master link, it is necessary to account for the link. Install one half of the master link on one side of the chain. Size the chain by cutting the other end of the chain.


If your chain is too short, you can jam your RD in large-large. If your chain is too long (as in this case), it may droop a little bit in smaller cog+chainring combos, but with 1 or 2 links too long, it will likely be insignificant (and occur in combos you don't use anyway).
