Firstly, sexing young and juvenile goldfish is virtually impossible, you have to wait until the fish reach breeding age (usually one year old).
Secondly, sexing adult goldfish out of the breeding season is difficult, because the sexually distinguishing features only develop during the breeding season (in the spring time). That said, females may be deeper in the body than males.
During the breeding season, the following physical features develop:
*males develop breeding tubercles (white pimples) on the gill covers and on the leading edge of the pectoral fins
*females develop a deeper body as they fill with roe (eggs), and have a larger vent (just before the anal fin) than the males

not just by looking at them. You would have to dissect them. It is really hard to get a fish to mate in capitivity anyway.
