The WIDTH of the chains is almost more important than the LENGTH.. The wider the crosslinks, the shorter the side chains can... and must... be, to fit a given tire.
The shorter the cross links, the Longer the side chains would need to be.
SO if you wanted to cover half the tire, that requires a fixed length cross link... and that would then determine the "length" of a 'laid out' chain assembly. I suppose it could be calculated but for most of us, maybe trial and error is easier. :-)
