The National Flag is in bottle-green and rectangular in size in the proportion of length to width 10:6, bearing a red circle on the length of the flag. Its center is placed on the intersecting point of the perpendicular drawn from the nine-twentieth part of the length of the flag and the horizontal line drawn through the middle of its width.
The background color symbolizes the greenery of Bangladesh with its vitality and youthfulness while the red disc represents the rising sun of independence after the dark night of a blood-drenched struggle.
