I could not really say, but I will see if I can figure it out by going to a conversion chart. Will post results. These were given to my daughters friend, and she wore them and she is about a size 8/10 range. But there is no tag on jeans stating a size. I almost feel like they are mens pants. But even so, she looked good wearing them. They are low ride slim leg.
