Racial Options

There are a few options to make your character fit the ideas you may have. The Ability Score Increase, Size, and even Languages can all be customized to better fit your character's history. Maybe you come from a very hardy people, like the Dwarves, but your character can't handle even the slightest cold breeze, but they make up for it with their incredible intellect. You could have been born of the tall and long Elves, but you find yourself barely coming up to some of their hips. Your Goblin may have been adopted by a couple of loving Genasi and they taught you to speak Primordial instead of Goblin. The options listed under your chosen race are just suggestions to easily fit your character within their culture's society, but you can change things up to make your character truly yours. There may be limitations set by the DM; rarely will you find a Large Fairy or a Tiny Goliath, but if you have a good story-driven reason for different character options, anything can be possible. Below are open-ended options for customizing your race.
Ability Score Increase. Increase one ability score by 2, and increase a different one by 1.
Size. Your size is within one size option of your race's average size.
Languages. You can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character.
