You are obsessed with really big weapons. With each rank of this perk, you gain an additional 15 points to the Big Guns skill.— In-game description

Size Matters is a perk in Fallout 3.


Each rank of this perk adds +15 points to the Big Guns skill.


  • Big guns-type player characters can find this perk useful, as it offers a large boost to the skill in question and can be taken up to three times, allowing a grand total of 45 skill points to be attained.
  • The value of this perk decreases dramatically due to the respawning Big Guns skill book U.S. Army: 30 Handy Flamethrower Recipes bug in the Bethesda ruins.


Icon xbox360.png Sometimes, if you add points to your Big Guns skill AND select this perk on the same level-up, your Big Guns skill will only reflect the 15 point increase of the perk. Loading the most recent save and leveling up again should fix the problem even if you assign your points and perk exactly like you did the first time. [verified]
