Replacing chains on old windows
I am refurbishing old wood windows which are 75 inches tall (full height of both sashes). The pulley for the chains are still in place but the chains are long gone. I have a source for replacements, but how do I estimate the length each chain needs to be? I was thinking 75 + 6 inches would be sufficient? You should not have any slack on the chain that holds the weights -- correct?
Any suggestions would be greatly appreciated.

I don't measure the chains/cords. I brace the top sash all the way in the upper position then tie or attach the weight so it's about 1/4" -1/2" from touching at the bottom. If you are trying to estimate a needed length for ordering I not try to cut it too close as extra can be cut off but too short is too short.

Found this formula on a website.
Estimating Length
For double-hung windows, the approximate total required amount of chain can be calculated by the following formula: (1/2 the sash opening height + 2 feet) x 4.
