For recommended wiggle dimensions consult Toradex, p. 22, figure 23, (reproduced below for convenience of discussion):
Here s = spacing between traces of a differential pair = 5mil (for our layout) w = width of traces in differential pair = 5mil (for our layout) Hence, Toradex suggests deviating away no more than 10mil and staying at that distance no more than 15mil. I would suggest spending less distance away, say 7.5mil before turning back so that we get more length at a 45 degree angle with the other trace which is where we make up path length.
