I'm Bon Crowder and the photos above are both of me - in 1989 and today. I'm a Generation X mom of Generation Z kids.

I began peer tutoring in high school in 1984. MathFour.com is the 2015 version of me helping peers be comfortable in math.

If you're a Gen-X parent, you're in the right place!

How to Find 20% of a Rectangle – The Facebook Page Cover Photo

I’m struggling with the new Facebook cover photo rules. You can’t have more than 20% of the cover photo as text.

But what IS 20% of the cover photo?

Let’s do the math!

The cover photo is 851 pixels wide by 315 pixels tall. Which is a total of 268,065 pixels. That’s a lot of pixels!

And 20% of that is…

268,065 x 0.20 = 53,613

Still, that’s an awful lot of pixels!

To figure out what that could be in reality, I picked on old Wolfram Alpha. Plugging it in there, I can get the prime factorization of 53,613.

3 x 3 x 7 x 23 x 37

Which breaks down into about five reasonable areas. And because this is all about seeing what those are (instead of just numbers), I created a handy infographic.

The light areas are the 20% rectangles – and you can move them anywhere.

Wow - finally some way to SEE what the max text of 20% of my Facebook Page cover photo should be!
