In a classic Christian cross, the vertical bar is divided into thirds above and below the horizontal crosspiece, which divides the vertical bar into thirds. The top portion of the vertical bar as well as the left and right sides of the crosspiece are all the same size.
Other Christian crosses employ a cross in which the crosspiece and vertical bar meet in the middle of both lines, such as those from earlier times or from Eastern Orthodox sects. All four of the cross’s arms are equal in length in this fashion. The cross is an iconic representation of Jesus’ death on a cross and subsequent resurrection.
