Constitutional and statutory basis
- The order is grounded on Article XIII, Section 1 of the Constitution, which prescribes what the Philippine National Flag should be without giving descriptions.
- The order is also based on Act No. 2928, which describes the construction of the Filipino Flag.
- The order addresses uneven compliance with Act No. 2928, which has produced disproportionate flag sizes and incorrect proportions of the flag’s allegorical symbols.
- The order is enacted to ensure uniformity by following both the Constitutional provisions and Act No. 2928 with consistent specifications.
Purpose and uniformity mandate
- The order requires uniform compliance to avoid irregularities and discrepancies in Philippine flag construction.
- Government branches must observe the specifications to prevent making flags with incorrect proportions of the flag’s symbols.
- The order mandates strict observance by all civil and military branches of the Government.
Flag size, geometric specifications
- The maximum length of the flag is twice its width.
- The minimum length is twice the altitude of the equilateral triangle.
- Any side of the equilateral triangle is as long as the width of the flag.
- The order requires that flag symbol layouts be measured using the specified geometric relationships tied to the flag’s width and the triangle.
Sunburst (golden sun) proportion rules
- The golden sunburst must be solid and must show eight rays equally spaced.
- The sun must have the form described in the accompanying illustration and proportion relationships:
- Arc x with sun ray = free arc y.
- Two opposite rays lie along the horizontal axis, and two opposite rays lie along the vertical axis.
- The sun’s diameter D = w/5.
- Each ray must have one major beam and two minor beams:
- The major beam is twice as broad as the minor beam on either side.
- The lengths of ray beams must follow:
- Major beam length R = 5/9 D.
- Minor beam length r = 4/5 R.
- The illustration governs the exact appearance and placement of the sunburst features.
Stars (three five-pointed stars) rules
- The flag must display three five-pointed golden stars of equal size.
- Each star must be oriented so that one point is directed to the vertex of the angle enclosing it.
- The star proportions must follow:
- The diameter of the circumscribed circle of each star is 5/9 D.
- The diameter of the inscribed circle of each star is 2/9 D.
- The placement rule requires that the distance from each corner = D/2.
Left trimmed canvas edge measurement
- The flag’s canvas-trimmed edge to the left of the triangle must be approximately D/5 wide.
- That left trimmed edge is not counted in measuring the length of the flag.
Silk flags trimming requirement
- Flags made of silk must be trimmed on three edges.
- The trim must be a knotted fringe of yellow silk with width D/5.
