Follicle size while taking clomid

Titania

I had my ultrasound done yesterday and my doctor told me that I have multiple follicles but one of them measured at 1mm to 2mm. when she said that she was saying it with excitment, like thats a good thing. but when I look at other people posts they follicles are measuring from 10mm to 13mm. So my question is does anyone know if the smaller the number the better or the bigger the number the better?
