A vertical is an alignment in which the top is always above the bottom. It is a property of two or more points in which if a point is directly below the second point, and they are vertical to each other. For instance, two balls are such that if the top one falls, it will always fall on the bottom one no matter what is the distance between the two balls, then the two balls are said to be vertical.


So any line or object that is moving upright or downright is vertical. Given below are some examples of vertical:


A different way of looking at vertical is through horizontal. Vertical lines or objects are always perpendicular to the horizontal lines or objects.  Some examples are shown below:

Movement can also be vertical; if we say that the motion is vertical, it means the direction of movement is top-down or bottom-up. 

Top-down direction

Top Down Direction

Bottom-up direction

Bottom Up Direction

Vertical lines in math

In math, the y-axis is considered vertical. Hence any line parallel to the y-axis is a vertical line. Also, vertical lines are perpendicular to the x-axis. 

 Given below are some examples.

Vertical Lines in Math

Line L in the given picture is vertical as it is parallel to the y-axis. 

  Fun Fact-

  • Although horizontal and vertical lines are perpendicular, all perpendicular lines are not horizontal or vertical. For example, the Leaning Tower of Pisa, the pillars of the tower are perpendicular to the floor but are not vertical.
