The best easiest way to determine chain length is to run the chain onto the largest rear and largest front combination, without running it through the rear derailleur.
Overlap the chain so that the small link lines up with a large link. Add another inch (Two links one small, one large ) and break the chain there.
You can try all the other methods but this is the easiest

The length of the old chain is NOT a good way to measure the new chain.
Bicycle chains stretch when they are used, and an old chain may be longer than when it was new.
You must count the links of the old chain, and then count the links on the new chain.
Usually the old chain is stretched about the length of one link, when laid down next to the new chain for comparison,

take the existing chain off and lay it on the ground or a table and lay the new chain beside it. this will tell you the best length for your chain. then all you need to do is put it on.
my personal chain preference is a Z-chain with the missing link (about $20). i race so my standards are pretty high and they have never failed me.
good luck

Check out the chains by SRAM or Shimano at www.pricepoint.com or blueskycycling.com ----they have lube available and you don't need math for these stuff-----if you got 8 or 9 speed drivetrains ---that's your ticket!!!

there will be a part where it is thicker, and it's just like two pieces on the sides holding it together. then, you can pull it apart and measure it.

Trial and error...Add and subtract links as necessary.
