I am quite new to design. I found a PSD kit for the iPhone 6 but the developer mentioned that it is in vector so i should not have any problem changing the size for the iPhone 6 Plus. The problem is in the kit they are segregated by the different views (profiles, signin, sign-up etc.). Per view there are like 5 artboards, 9 artboards etc.
So my question is how I can change the size of only one artboard?
