If you play ring game there is no need to increase the blinds. You can then use 0.5/1 or 0.25/0.50

If you play tournament then it depends on the duration of time you want for the tournament and the number of players, as well as your speed of play. go to www.homepokertourney.com, they have tons of useful information about home tourneys.

Another issue - the correct terms are small blind and big blind, not little blind and big blind
