"You are a bit tall."
Here is what the course notes say:
We’ve already seen how to complain politely by adding 有点儿 (yóudiǎr, a little too much) before an adjective (for example, 有点儿贵). Use a slightly different phrase, 一点儿 (yìdiǎr), before nouns to talk about a small amount of something.
I'm not sure 有点儿 is always a complaint though. It looks like 有点儿 is for adjectives, and 一点儿 is for nouns.
