Open Question: How much protein should i eat everyday?

I weigh 125-130lbs, im 5'4", and i was just wondering how much protein should i be eating per day just to be healthy? I've looked around on the internet but every site says something different. I do want to gain muscle but i dont weight train i just use my body weight.(Yoga, push ups, pull ups, etc.) So i don't know if that matters?
