Where are you seeing the small font sizes? Is it within a specific channel/app, or do you feel that way about everything? If it's within only specific apps, Roku can't control that. Unless it's within The Roku Channel, which Roku does control. Naturally, the size of TV you're viewing on is going to have an impact on the visuals. My two primary TVs we use with a Roku are 55", and even from across the room I don't feel I have a problem reading the screen. And I'm almost 70 and wear glasses/contacts.
