Speaker cable lengths doe it matter they are not equal???

Hello to all ...
This is my first time on this site so please pardon my "rookieness" at this. I am setting up a new system after being out of audio for years. My current setup demands that one speaker is relatively close to the components and the other not so much. In other words they will not be equidistant forcing me to have one speaker cable longer than the order a rough estimate is that one will be 8 feet and the other 16-20 feet.
The question is what is best:
1. Leave them different lengths
or
2. Make them the same length and hide the excess as best as possible on the closer speaker (would end up being coiled)

i understand that presumably the impedance would differ because of the length difference but would that be noticeable?? As I said I am no expert that’s why I came here to hear feedback from the experts out in audiogon land!
Thanks for your replies lets see what you all think........
