How is car seat "height" determined?

The Safeseat is supposed to have a "Height" of 32" as its limit.

And my baby is long in the torso, not the legs (He's growing into 18 months bodysuits and just got into 12 mo pants. The 18 mo are way too big).

Yet he is 31.5" long, total, and has quite a bit of room over his head in the seat, more than just 1/2" (And I thought he'd outgrow it before hitting the height because of the long torso thing)

I think it's partially determined by growth chart heights, like that seat is labeled to fit 97% of kids to age one, so maybe that's the number on that part of the growth chart? Other seats go by the 22lb/29inch 1 year old crash test dummy. I don't know what Dorel is thinking with the 34 inch FF minimum limit on their convertibles, though...seems kind of random. Britax claimed the Marathon maxes of 65lbs and 49 inches were based on the 6 yo 90th percentile child (admittedly, I didn't whip out the CDC chart to double check them :whistle:). Of course overall standing height doesn't mean that much when kids are SO differently shaped...I'm sure some 29 inch long torsoed kids are too tall for the SS1, and some 34 inch leggy kids still fit (like Leah did...)
