Single Speed Calculator
This calculator will give you a chain length and the amount of slack that needs to be taken up by a tensioner. It is assuming you are using a non-single speed frame with a "hacked" tensioning device (e.g. Blackspire Stinger) which only tightens one side of the chain and has limited adjustment range.
