How many paragraphs are in a newspaper article?

It depends on the kind of magazine, how many pages it publishes, whether it's a weekly or a monthly, and whether it is known for short articles, or long-form journalism. For example, a news magazine (like The Week or Time magazine) will have short articles about such topics as politics, health and medicine, world news, the economy, nature, celebrities, movies and entertainment, sports, etc. They will also have a longer cover story, which is more in-depth. Some weeks, the magazine might feature more stories about one topic-- if there's an election going on, the focus might be more tied in with political coverage, for example.

There was a time before the internet when magazines had a fixed number of stories; some magazines still follow that rule. But these days, magazines try to be more flexible and react to changing trends, without losing their identity. That's because many magazines today publish an online version, and they may have new stories which change frequently, allowing them to address whatever the top issues are. Thus, some weeks (depending on how much news there is), the online version of certain magazines might have as many as 15-20 new articles, to meet the audience's expectation of up-to-date reporting.
