The green field represents the lush landscape of Bangladesh and the vitality of youth. The red disc represents the sun rising over Bengal, and the blood of those who died for independence.
History
Adopted on January 17, 1972. The original design during the 1971 Liberation War included a yellow map of the country inside the red disc, which was removed for simplicity.
Construction
A 3:5 ratio. The red disc is slightly offset toward the hoist so that it appears centered when flying.
