+1 to almarg & murphyb74. Here's another chart: http://www.roger-russell.com/wire/wire.htm#wiretable. I went to 10 AWG KnuKonceptz cable all around with soldered Audioquest spade terminations and picked up audibly better definition and frequency response. All of my speakers are 8 ohm nominal impedance and my rear surrounds are 40 and 45 foot runs, respectively.
There are some older threads that address the topic of different speaker cable lengths. You can decide for yourself after you read through them. good luck & happy listening!
