Print this in a big enough font so that you don't have to squint at the page when you're referring to it. Spacing is good, different colors or lines after every topic will help you keep your place during the class. You should make notes on here as well. The handout is a different matter. On your handout, there should be less detailed facts and more graphics or pictures.
Students like to make notes during a class.
If you put all of the details in the handout, it will be a great handout, but the student won't get as much out of the class and will feel like you are just reading from your handout. Let them make the notes. Remember to give credit where credit is due and always include a source page. Don't forget to put your name and contact information on the handout as well. When your class is ready, try to give it a run through before hand, either before an audience of friends or alone.
