What does Calvin look like in the book a wrinkle time?

Calvin O'Keefe, the protagonist of Madeleine L'Engle's "A Wrinkle in Time," is described as an ordinary, average boy. He is not physically remarkable in any way. Here's what the book tells us:

* Appearance: He is described as being "tall and thin" and having "brown hair and brown eyes," which are "ordinary."

* Personality: He is more defined by his personality than his physical appearance. He is intelligent, brave, and kind, but also insecure and often feels inadequate.

* Dress: His clothes are not described in detail, but he is likely wearing typical school clothes.

Therefore, Calvin is not a character who is defined by his physical appearance. His true nature is revealed through his actions, thoughts, and interactions with others. He is an everyman, representing the potential for greatness that lies within all of us.
