50", about 20 lbs at 20" draw. rememeber to keep the limbs thinner, at least for me when makign kids bow that are lightweight, if the limbs are as wide as an adult bow then they will need to be much thinner to get the drawweigth down. it is a lot trickier to tiller thin limbed bows that ones with thicker limbs, at least for me. so making the limbs thinner in width (~1") will allow for more wood in thickness. just my thoughts i could be wrong, but it works for me.
