What is the appropriate size of fish tank for a beginner to buy?

[Rank Wang]

I plan to buy a new fish tank.
After looking for it for a long time, I decided to order it from this store https://www.reihey.com .
However, I don’t know what size it will be and it will take a long time to customized it.
Is there any ready-made one you can recommend?

There are almost unlimited options. The real questions are:

How much space do you have
What fish do you want to keep
What is your budget

With that info, we can offer plenty of guidance
