Yikes, every one has something different to say here.
Average tank is 10 gallon. Gold fish are pond fish and have certain requirements. Mostly cooler water and lots of dissolved oxygen. and they grow quickly. With that being said,
Two goldfish can live happily in a 10 gallon tank. Yes, they can grow up to 12 inches plus, out of that 12 inches 4-5 of it is tail and isn't counted as useable size when it comes to fish tanks, only in legal fishing catches. Even when they mature if the proper water conditions are maintained. They will not be harmed or stunted in a 10 gallon. I have raised various gold fish and Koi for years, and use to show them (yeah they have shows for gold fish)
Filtration on your tank is the most important thing for your fish other than a quality and varied diet. You will also need to keep an eye on the ammonia levels. Your fish can and will live a long healthy life.
I just hauled out of my basement 10 20 gallon tanks. I was housing for my Fish store after their fire in January. 3 of the tanks were gold fish tanks with more than 30 gold fish. of different sizes. 3 months, I didn't loose a fish even though conditions seemed over crowded. I am not saying keep 30 fish in a 20 gallon.

Gold fish grow from 8 - 16" or so adult size. Typically a fancy goldfish needs 15 to 20 gallons to be healthy and comfortable. A common goldfish or comet would require far more than that as they are the larger one's of the group. So if average sized tank is 10 gallons you should keep no gold fish in it. If average is 20 gallons then one.
By the way, that 1" per gallon rule you hear so much about it completely and totally broken. It is one of the worst problems that has ever plagued fish keeping. You can see that from the answers above that quote that "rule". It leads to a complete misunderstanding of how tanks should be stocked.

Wow, you are getting a lot of bad advice.
If an "average" sized fish tank is 10 gallons (and I'm guessing it is), you shouldn't keep any goldfish in it. Go with some smaller species of fish.
Please remember that the size the fish are at the pet store is not the size they will stay. Those at the pet store are juveniles and have a lot of growing to do. Do some research on any species of fish you buy...BEFORE you buy it. That is the only way you will know if it is appropriate for your tank.

Average size? Well that can vary i guess.
If you really want to have healthy goldfish that will live a long time...you need at least a 30 gallon tank. And that could hold 2 or 3 of them. I personally think it is cruel to keep them in anything under 20 gallons.

The important dimension for calculating the stocking density of an aquarium is the tank's surface area in cm squared. This means you don't actually need to know how much water will fit in the tank to know how many fish go in.
Surface area = length * width. Cold water fish require 194cm squared per 2.5cm of fish. Tropical fish require 64cm suared per 2.5cm of fish.
The reason for this is the surface is the main part in contact with air meaning this is the main source of oxygen. Put too many fish in and they suffocate. We had to do a whole essay on this for Management of Exotics at college

It's all dependent on a bunch of things. Here's some variables.
Size of the fish.
Type of goldfish
water temperature
water quality
food quality (does it pollute the water?)
size of the tank
how often tank gets cleaned
Do your research with these particular variables. There are a lot more than just these, but if you can get down to a ballpark figure, and doing proper maintenance, you should be OK!

well i'm not sure how big an 'average' sized fish tank is. General rule of thumb for freshwater is one inch of fish per gallon of water. So you can fit about 5 goldfish in a 5 gallon tank (if they are small).
Personally i'd cram more in if i wanted to. Goldfish aren't that picky about space. However the more fish you have per gallon of water the more water changes/cleanings you'll need to do every month. One fish swimming in 5 gallons of water will take it longer to make a mess of it's tank. But if you have 7 guys swimming around in there the amount of debris will collect a lot faster and will require cleaning more often than if you only had 1 fish. Up to you :)

I'm not sure what you mean by an average size fish tank as there are so many different sizes, but one goldifsh needs 10 gallons of water as they grow large and produce more ammonia then tropical fish. So if you have a 20 gallon, you could have 2 goldfish.

i have heard that you need a gallon for each fish. Are these goldfish average size themselves? I have had 15 smaller gold fish in a 10 gallon tank, and then moved them up to a 20 gallon to let them grow more. I have heard that gold fish won't out grow their space. Only what i have heard, maybe i am right or maybe i am wrong. good luck
