Chain round chainring and biggest cog + two links has always worked a treat for me. Just if its half way, go a little longer. The longer the chain the more likely that it will make bids for freedom if you aren't using a clutch mech or n-w chainring.
Thanks for the input, both. I watched a few videos on youtube and the 'biggest cog/chainring +2 links' method seems a sensible way to size the chain. The one I removed is well knackered.
