Find a metric conversion table and go from mm to inches, that will tell you.

Normal pupil size is between 4-7 mm in darkness, with some people having pupils as large as 9-10 mm. I do not have the exact conversion table, but you can just take any ruler and it will have both mm and inches

Open request to the doctors of asklasikdocs.
Can I get you to send me jpg's or a video clip if available of what a starburst and halo is supposed to look like?
I have two types of night halos outside that surround flood lights and car lights.
Colorful jpeg's or video clips would be preferred, around white,red any kinds of lights.

It is not uncommon to have both starbursts or halos shortly after LASIK, related to any of a number of possible causes. A halo refers to a ring of light surrounding the light that someone is looking at (like the halo that is depicted around the head of an angel in paintings), while starburst refers to twinkling of a light (like when you look at the stars in the night sky).
I honestly do not think that any of the doctors are going to try to draw a jpg photo of a halo or starburst - although you may be able to find a drawing of one at surgicaleyes.org
As I have written in many of my other posts to your same question - there are multiple causes of halos and starbursts (the causes are the same for both), with the most common cause being that you have a slight level of myopia and/or astigmatism. As your eye heals, the halos/starbursts often resolve. As well, if you have residual myopia/astigmatism, glasses or contacts at night will eliminate the halos/starbursts.
I hope this helps
