Size of giants then and now

[Dmdork]

3.5 had large Giants, 5e has huge Giants. Yet the 5e version of the Against the Giants module has the same size maps as the 3.5 one. Ever notice that? 5e Giants are considerably bigger, so the Hill Gaint Steading for example should be considerably larger. I mean it's an easy fix, just change the key from one square=10feet to one square=15 feet. Am I reading this right?

Battlemap spacing is required for combat only. Hill Giants according to the MM are only 16ft tall, and less than half as wide as they are tall. During normal day to day activities, they can work just fine, but in combat, they have to use the squeezing rules (Half Movement, effectively).
