It can never be shorter than a component - magnitude of a vector is the square root of the sum of the components squared, and a square function never produces a negative number. However, it can be the same size as it's component, if that component is the only one.

A vector's magnitude cannot be shorter than any of its components as it is derived from their squares. However, a vector can be equal in length to one of its components when it has only one non-zero component. For instance, a vector like ⟨ 3 , 0 ⟩ has a magnitude equal to its x-component 3.
