I have had fancy goldfish for 5 months now and I'm just wondering how long it takes them to get to full size.

Several factors to consider here, such as water quality, nutrition, type of goldfish/genetics and space. With a good diet, clean water and plenty of space, most of their growing will take place during the first 2 years and they will continue to grow at varying rates for the rest of their lives.
