Here is Facebook’s own information on sizes and allowance and their reasons for changing the text allowances for your reference:
The company is developing a grid-based text overlay detection tool to identify non-compliant images. A version of this tool will be available within Power Editor to help advertisers know in advance whether their images will be approved. Advertisers should keep in mind that text within logos will also count toward the 20 percent limit.
Ads and sponsored stories for News Feed that originate from Pages may not include images with more than 20% text (effective January 15th, 2013)
Facebook people react negatively to content that they perceive as inauthentic or impersonal. Since text is rare in photos from friends, text in brand photos triggers negative emotions in people. Instead of introducing text in your images, choose photos that send a message or tell a story on their own without words.
