The current flag of Guyana was officially adopted on May 20, 1966. The flag consists of a horizontal rectangular design and two triangles. The officially recognized proportion of the flag is based on a length-width ratio of 3:5. The flag features a large green field and two large triangles. One red isosceles triangle is located on the hoist edge of the flag and is superimposed on a golden triangle whose edges are white. These two triangles are pointed towards the flag’s fly side. The border of the two triangles is a black band.
