I reckon right now they're all about 9 or 10 (I tried working out a timeline and reckoned that Naruto and Hinata got married at 19/20, had boruto at 20/21, and that Naruto became Hokage at 29/30, and this takes place a little bit after that (a year or two at most I'd reckon)). Since they seemingly graduate at 11 or 12 it's a bit weird that they're supposedly getting a well-rounded education but they're at school for such a short space of time - Naruto, Sasuke etc were all at the Academy from about the age of 6 or 7.

However, if Iwabee is right about when the war ended, it would make them 6 or 7, in line with their parents' ages for attending the academy...although they look much older.
