The official design of the national flag was adopted by the Constituent Assembly together with a definition of the features and proportions.

According to the specifications it is a dark green rectangular flag in the proportion of length [A] and width [B] as 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 width of the white portion [C] is one quarter the length of the flag [A], nearest the mast, so the green portion occupies the remaining three quarters [D]. Draw a diagonal L3 from the top right hand corner to the bottom left corner of the green portion. On this diagonal establish two points P1 and P2. P1 is positioned at the centre of the green portion and P2 at the intersection of the diagonal L3 and an arc C4 created from the top right hand corner equal to 13/20 the height of the flag [E]. With the centre at point P1 and a radius 3/10 the height of the flag describe the first circle C1 and with centre at point P2 and a radius 11/40 the height of the flag describe a second circle C2. The enclosures made by these two circles form the crescent. The dimensions of the five-pointed white heraldic star are determined by drawing a circle C3 with a radius 1/10 the height of the flag positioned between P2 and P3 on the diagonal L3. The circle surrounds the five points of the heraldic star and star lies with one point on the diagonal L3 at point P3 where the circle C1 intersects the diagonal L3.

The flag is colored in Pakistan green having standard RGB values (red = 0, green = 64, blue = 26) or with hex triplet #00401A or the HSV value = (h = 144, s = 100, v = 25). The left strip, the star and the crescent are painted in white. The flag is supported from left white side.
