All that stuff about size is silly. The real thing to worry about is "How long should it be?" — the question every student has asked since a teacher assigned a report on topic (fill in the blank) for homework. 

Length has grown nothing but more important in the online world, a fact anyone who has struggled to trim a too long tweet understands. 

So how many characters long should a tweet be to get the most engagement, or how many words long should a blog post be so that it actually gets read? The team at SumAll, a company that markets a social media analytics and business dashboard, knows.

Picture This

If you automatically associate tweets with 140 characters, read on. The ideal tweet is between 71 and100 characters, leaving extra room for retweets and comments. Six character hashtags perform best. And blog posts? Well, they can optimally be longer than you may think.

But what do we know? We didn't create the Ideal Length of Everything Online. SumAll did — and we're sharing the company's excellent infographic.

Forget the fact that we prefer to give you our own original infographics. Sometimes you gotta break the rules, especially for something as useful as this. 

Mark Uzunian, the editorial director at SumAll, shares credit for the infographic with the team at Buffer, a social media management platform. As he noted in his blog post, "To make all this data digestible and easy to understand, we partnered with our awesome friends over at Buffer to produce an infographic that shows the optimal length of pretty much everything on the Internet."

Take a look. Or print and save. Some things are worth a sheet of paper.
