Armor comes in five sizes: Very small, small, medium, large, and very large. It's possible to wear armor that is one size off from your size. Here are the races that fall under each size:
|very small||Bimm, Dug, Jawa, Ewok|
|small||Bothan, Sluissi, Noghri|
|medium||Anzati, Chiss, Clawdite, Devaronian, Duros, Echani, Falleen, Gand, Gank, Human, Mon Calamari, Quarren, Rodian, Shistavanen, Sullustan, Togruta, Twi'lek, Verpine, Zabrak|
|large||Aqualish, Defel, Ithorian, Gungan, Gamorrean, Gotal|
|very large||Barabel, Trandoshan, Togorian, Wookiee|
You may have armor refitted at any of the armor refitting shops throughout the galaxy, or by players using the resize skill. You may see some armor that is 'unsized': Unsized armor automatically sizes itself to the race of the first being to wear it.
