The height of the shield is 1/2 the width of the flag. The flag is double-sided. The top of the pole is a metal cone 1/10 of the width of the flag, the base of the cone is equal to two times the diameter of the pole.

The reference model of the flag is kept in the office of the speaker of the Oblast Council.
During the rule of the Tsardom of Russia, Russian Empire, and Soviet Union, Kharkiv did not have its own flag. However, from either 1651 or 1659 to 1765, the city was the regimental center for the Kharkiv Regiment, which had its own flag, which was used at times to represent the region. The banner consisted of a cross in a glow and above it two angels with trumpets holding a crown.[1]
