Is it 4-8cm Or 6-12cm
I've seen both online, which one to go with, is 10 cm considered enlarged, o think there was a Uworld question with 10 cm trying to make the point that the liver was enlarged?
Normal in adults is 14 +/- 1.7 cm. 74th%tile is 15 cm.
1 in 8 people is normally >16 cm.
At age 5, it's ~5 cm.

In my experience with 2CK Qs, if they tell you the liver span in centimeters, it's generally normal. When they're trying to tell you there's HSM, they'll almost always say "liver can be palpated below the lower rib margin."
Just stumbled across it on UWorld: 6-12 cm in the MCL (QID 4278 in the Step II QBank).
I'd also go with what Phloston said if you can't remember. I can't remember a time where they said the tip could be palpated "x cm below the margin" that it wasn't hepatomegaly.
