@Gamera , you might want to start out with a concert sized guitar. It’s a little bit of a smaller body than a full size guitar, and depending on the manufacturer they can sound beautiful.
But concert guitars are super comfy to hold and play. I actually prefer my Taylor GS Mini over all my other guitars.
Yamaha makes some great bargain concert guitars, great sounding and very reasonably priced.
Lessons might be a good idea to learn basic chords and basic music theory behind the fretboard.
YouTube is also a great source for learning songs and scales.
Let me know if you need any help.
