How Can I use font size properity?

Dear Sir,
For those unicode controls, I had try to use font size properity to change it's visual effect but it does not. Could you tell me if it does not work or I miss something. Thank you very much.

You probably have set the UseSystemFont property to True. In this case the Font property is ignored and the system font is used. Set UseSystemFont to False in order to use a custom font.

Thanks for your clarify.
