I need Pinyin input method font size 20

I am using Mac's own Pinyin input method, candidate word size 18 is too small, 24 is too big, the middle of the 20 and 22 options should be more appropriate, but currently does not support selection, I hope to increase these two options, maybe this is most people's favorite size
