Depends on how you anchor, the ATA of your bow and your draw length.

Normally with modern compound using a release though anchoring the arrow to the corner of your mouth would be a pretty high anchor.

I like to have my string touch the tip of my nose and have the string lay across the corner of my mouth with the fletching of the arrow touching the space between my lip and chin or in that area, depends on the set up.

Here is a pic of me at full draw with my bowtech mighty might. I think it has 31 inches of ATA and 26 inches of draw length (I'm a little dude).



I'm not posting this as a how to on form or stating that I have perfect form, just giving you an idea of what I am talking about.
