The Mayo Clinic [0] says the recommended daily intake for adults is 38g for men or 25g for women. A little less if you're over 50.
The USDA [1] makes their calculations from a proportion of 14g fiber for each 1000kcal consumed - if you're an adult male with a healthy diet you're likely consuming around 2000-2500kcal, which puts your fiber needs at 28-35g per day.
You probably need more of it, but I'm not a doctor and even less *your* doctor, so please don't just take my word for it. :)
