Small Frame

Small Frame is a trait which appears in Fallout, Fallout 2, Fallout: New Vegas, Fallout Tactics, Van Buren, Lionheart and J.E. Sawyer's Fallout RPG.

Fallout and Fallout 2
You get a +1 bonus to your agility, but your carry weight is equal to 25 + (15 lbs. x your strength).

Fallout: New Vegas
Due to your small size, you have +1 agility but your limbs are more easily crippled (25% extra limb damage). This detrimental effect can be nullified by taking the Adamantium Skeleton perk. Overall, just taking Intense Training for agility is a more efficient option than taking the Small Frame and Adamantium Skeleton combination. You cannot gain Adamantium Skeleton until you reach level 14, but Intense Training can be taken at level 2. The bonus from Small Frame is more detrimental early in the game due to the lack of good armor and healing supplies. By the time you reach level 14, you likely are not hurting too much from the negative aspects of this trait to be worth taking a perk to negate it. The Tough Guy challenge perk, does negate most of the negative effects of Small Frame without requiring you use a level up perk slot. Most people, even with Small Frame, do not end up getting it because it requires getting your limbs crippled 50 times. This trait is not recommended for Hardcore Mode, due to the fact that you cannot heal crippled limbs with Stimpaks; rather, you must use a doctor's bag or visit a doctor to heal crippled limbs.

Fallout Tactics and Lionheart
You are not quite as big as other people, but that never slowed you down. You can't carry as much, but you are more agile. You get a +1 bonus to your agility, but your carry weight is 50 pounds less than normal. Feralkins may not take this trait.

J.E. Sawyer's Fallout RPG
You are smaller than average. It's hard for you to carry heavy loads, but it's easy to avoid the lumbering giants of the wasteland. -50 to carry weight, +2 to evade.
