The magnitude of a vector is indicated by the of the arrow.

Size

Explanation:

A vector is a quantity that has both a direction and magnitude.

The direction the arrow is pointing represents the direction of the vector, and how big the arrow is represents the magnitude.

You can remember this as "magnitude" means the exact same thing as size.
