Sweater help

I’m a new knitter but i’m tired of making scarves and would like to move on to sweater, I want to make one for my daughter but i don’t know how to start , I don’t know how to do the arms and i don’t know the measurements since i don’t have any patterns. Can someone please help me with how to start out and how to measure and so forth.

Thankyou
