Which line helps show a feeling of height?

Correct answer: Vertical line

Direct answer: A, a vertical line. A vertical line extends upward and downward, so the eye naturally follows its upright direction. In a drawing, this direction can suggest height, standing, growth, strength, or an object reaching upward. A is correct because it most directly communicates the idea of height. B is incorrect because a horizontal line extends across the page and is more often associated with width, rest, or a stable surface. C is incorrect because a curved line mainly suggests bending, softness, roundness, or flowing movement; it does not give as clear a height cue. D is incorrect because a diagonal line suggests slanting movement, action, or instability rather than purely upright height. A line’s meaning can change with context, but the basic visual association remains useful for beginners. Memory cue: vertical lines stand up; horizontal lines lie across.
