Specifications :
The Pakistan Flag is a dark green rectangular flag in the proportion of length to width 3:2 with a white vertical bar at the mast; the green portion bearing a white crescent in the centre and a five-pointed white heraldic star.
The size of the white portion is one-fourth the size of the flag, nearest the mast, the remainder three-fourths being dark green. The dimensions of the crescent and star are obtained as follows:— Draw the diagonal from the top right-hand corner to the bottom left-hand corner of the green portion. On this diagonal establish two points ‘A’ and ‘B’. Point ‘A’ should be equidistant from top right and bottom left-hand corners of the green portion, i.e., the centre of the green portion. Point ‘B’ should be at a distance from the top right-hand corner equal to 13/20th of the width of the flag. With point ‘A’ as the centre and a radius equal to 3/10th of the width of the flag describe an arc. With point ‘B’ as centre and a radius equal to 11/40th of the width of the flag describe a second arc. The area enclosed by the two arcs forms the crescent. The dimensions of
the five-pointed white heraldic star are determined by drawing a circle with a radius equal to 1/10th of the width of the flag. The circle surrounds the five points of the heraldic star. The star lies with one point on the diagonal and pointing to the top right-hand corner of the flag. The tip of this point lies on the diagonal at a point where the larger arc, if completed, would cut the diagonal.
