Size Matters is a perk in Fallout 3.


You are obsessed with really big weapons. With each rank of this perk, you gain an additional 15 points to the Big Guns skill. With all three ranks, players can gain a +45 bonus to Big Guns.


  • Big Guns-type players can find this perk quite useful since it offers a large boost to the skill in question and can be taken up to 3 times, allowing a grand total of 45 skill points to be attained.
  • It's worth noting that the value of this perk decreases dramatically due to the U.S. Army: 30 Handy Flamethrower Recipes book that respawns in Bethesda Ruins.

Behind the scenes

  • In the perk image, Vault Boy is shown wearing a bandana and sporting a beard. This may be a reference to John Rambo in the action-film series Rambo.
