My method. Bike in neutral. First you have to find the tightest position of the chain by rotating the rear wheel and checking. Normally there is some variation with all chains so don't be alarmed. Pick a spot equal distance between front and rear sprockets. I will just lift the lower length of chain and measure for the proper amount of slack. I use as much force to lift the chain as I would to pick up a cup of coffee. It works for me but others will chime in with their advice too. A little extra slack is better than being a bit too tight.
