Hi Cheryl
My immediate kneejerk response to this question, was "if you haven't noticed them, they are the normal size".

I immediately went to my neck to feel the size of the lymph nodes and realised I only notice them when they are enlarged with infection. I know they are there somewhere and are about 1cm big when not infected or growth affected. I believe the size is varies, depending on which lymph nodes you are asking about. I have assumed you are asking about the ones under your jaw that your mother or doctor used to feel around for when you complained of feeling unwell?

Why are you asking?
