She actually doesn't have this tattoo any more. So, you might want to take a hint and avoid putting anyone's name permanently on your skin.
But, if you are determined, you can certainly take the picture here:
to any good tattoo artist and they can recreate the font. I doubt that this is a standard font. It's probably something made specifically for her. It definitely looks Gothic to me.
When you get a tattoo, you really don't worry about font size.
When I got my tattoo, I searched for weeks until I found the perfect one. Then I took the picture to the tattoo artist, showed them what I wanted and they did it perfectly.
Your best bet will be to take the pic in and have them try to copy it. Any good tattoo artist can do it. If the one you choose, can't, you need to go to a different one.
I hope this helps! Let me know if you need more help.
There are a few fonts I found that resemble that one.
