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!

  1. What a great tool! I’d love to use this in a presentation on Facebook that I’m doing this weekend if that’s alright. I’ll be sure to give you all the proper credit!
