It's like making an internet meme, except it's not about meme.
I am learning English vocabulary, and I think that a meme-like image will help me a lot to memorize the word. It has a picture and a (short) description. However, I'm not sure how to add the text properly. The font using in memes is Impact, but it is used because of the widely distribution of it by Microsoft*, not because of any rationale.
Moreover, the popularity of the font using in meme makes me instantly feel that every picture with a line of text in that font will be a meme, before I even start looking at the picture and reading the text. It could be a little childish to use a meme-like picture in formal context like in a presentation.
Q: So what font should I use to add at the bottom of the picture?
And by the way, how should I choose the size of it?
