Non-Human Tieflings (and Aasimars) and Size Bonuses

In game terms, the difference between non-human tieflings and human tieflings is purely a matter of size. Unless they have specific tiefling-related size modifiers, the tieflings of each of these races are the same size as their non-fiendish ancestors. They gain any of the bonuses or penalties related to that size, but gain no racial bonuses except those of the tiefling; beyond size, their humanoid ancestry is purely cosmetic.

So if they gain all bonuses and penalties related to size, does that include the ability scores increases and decreases related to going up or down in size from the bestiary? It might be wishful thinking but it just doesn't seem right to me that a tiefling born to ogre parents is no stronger then the average human, and in fact is faster!

Please help.

Such is the curse of such a Tiefling. He's far weaker than his peers. On the plus side though, this does make it a little easier to work a large Tiefling into a game.

This also means a Tiefling born of Halflings is stronger than his kin.

To further clarify the reason for this. Although there are rules in place to note changes in Ability Scores for 'advancing in size', those aren't ACTUAL changes related to size. That's something that happens when a creature's size changes through advancement.

Any racial adjustments to ability scores are exactly those: Racial, not Size.

Note: You can be a Tiefling of different heritage, as well as size.

So, you could be a small-sized Oni-Spawn Tiefling.
