Hi
@Jinsun, my angels are Small and Large with diamond granulation (the smallest and largest in pics), and Small w/ diamond pave bezel (the middle size in pics). In width, from smallest to largest, they are approx. 12mm, 15mm, 18mm. Here are some reference pics.
If you're looking for one larger Angel to wear as a pendant, you might prefer the Extra Large (with or without diamond granulation) or the Large with diamond pave bezel. Those are approx 22mm and 25mm wide, respectively. I tried the Medium with pave bezel and for me, worn on its own, it felt a bit small as a stand-alone pendant. But, all so personal.
