Specifications of the Philippine Flag

The flag's length is a maximum of twice its width.
The minimum length equals twice the altitude of the equilateral triangle present on the flag.
Each side of the equilateral triangle is equal in length to the flag's width.

The sun on the flag is solid golden with no markings.
It features eight rays, equally spaced around the sun.
The diameter of the sun (D) equals one-fifth of the flag's width (w/5).
Each ray includes one major beam and two minor beams on each side.
The major beam length (R) is five-ninths of the sun's diameter (5/9 D).
The minor beam length (r) is four-fifths of the major beam's length (4/5 R).
Rays are positioned such that two are along the horizontal axis and two along the vertical axis.

Three five-pointed golden stars of equal size are positioned on the flag.
Each star is oriented with one point directed to the vertex of the angle enclosing it.
The diameter of the circle circumscribing each star is five-ninths of the sun's diameter (5/9 D).
The diameter of the inscribed circle within each star is two-ninths of the sun's diameter (2/9 D).
Each star is placed at a distance of half the sun's diameter (D/2) from its respective corner.

The canvas-trimmed edge to the left of the triangle is approximately one-fifth of the sun's diameter (D/5) wide.
This canvas trim is not counted in the overall length measurement of the flag.
Flags made of silk are to be trimmed on three edges with a knotted yellow silk fringe, also D/5 wide.

The specifications are mandated for strict observance by all civil and military branches of the Philippine Government.
The order was promulgated to ensure uniformity and prevent irregularities and discrepancies in the flag's representation.
