Sam has blonde shoulder length hair with a teal streak in her bangs. She has two helix piercings in each of her ears and wears pink eyeshadow.
Her outfit consists of a short, teal leather jacket with a crimson patch bearing a white skull on the back, a white T-shirt with the roundel of the RAF on the front, a pair of deep burgundy jeans ripped at the knees, a black belt with silver studs, and a pair of dark purple boots.
According to Kevin Sullivan, during his first pitch of "L is for Love", Sam was named Max, which is also a unisex name.
Contrary to popular belief, Sam was not named after writer Sammie Crowley, as Kevin Sullivan stated that he wanted her to have a name that both males and females could use, which would add in confusion to what Sam's real gender was.
Kevin Sullivan said Sam will be in new Loud House comics, and Listen Out Loud podcasts.
