Reduce / Enlarge Person

[Mantipper]

Reduce Person:

This spell causes instant diminution of a humanoid creature, halving its height, length, and width and dividing its weight by 8. This decrease changes the creature's size category to the next smaller one. The target gains a +2 size bonus to Dexterity, a -2 size penalty to Strength (to a minimum of 1), and a +1 bonus on attack rolls and AC due to its reduced size.

Enlarge Person:

This spell causes instant growth of a humanoid creature, doubling its height and multiplying its weight by 8. This increase changes the creature's size category to the next larger one. The target gains a +2 size bonus to Strength, a -2 size penalty to Dexterity (to a minimum of 1), and a -1 penalty on attack rolls and AC due to its increased size.

When a creature is recuced/enlarged, does it also gain the benefits/penalties normally associated with the new size not listed in the spells? I'm referring to the CMB/CMD, Fly, and Stealth bonuses/penalties listed in the creature size chart on this page. Or do the spells technically take those into account with the strength/dexterity changes?

yes you add them, no the spell doesn't figure them in, only the +1/-1 to attacks from size does it mention, but everything based on size changes.
