Bangladesh’s current national flag has a red disc on a bottle-green rectangle. The hoist-to-fly ratio is 3:5. The disc sits halfway up the field and slightly toward the hoist; its radius is one-fifth of the fly length. [2]
Specification
Article 4(2) of the Constitution defines a red circle on green. Article 3 and the Second Schedule of President’s Order No. 130 of 1972 supply the detailed specification. “National Flag” is the statutory designation used here. [1]
Physical color specification
The Second Schedule names Procion Brilliant Green H-2RS at 50 parts per 1000 for the field, and Procion Brilliant Orange H-2RS at 60 parts per 1000 for the red disc. The dye name “Orange” does not change the legal description of the disc as red. [1]
Specimen screen colors
#006747 / specimen approximation#DA291C / specimen approximationThese values come from the selected SVG. No statutory HEX, RGB, Pantone, or RAL equivalence is established by the cited legislation. A screen swatch cannot replace the textile specification. [5]
Construction notes
For a fly length L, set the hoist to 0.6L, the disc radius to 0.2L, and its center to (0.45L, 0.3L), measured from the upper hoist corner. These are direct conversions of the Second Schedule’s 10-by-6-foot example. The resulting diameter is two-thirds of the hoist. [1]
In the specimen’s 10 × 6 viewBox, the circle is at (4.5, 3), radius 2. Its center is 0.5 unit closer to the hoist than the field’s midpoint. The oversized background rectangle is clipped by the SVG viewport; the visible field has the prescribed ratio. This is geometric verification of an editorial specimen, not certification of manufactured cloth. [5]
Historical record
The Bangladesh Embassy’s 2019 independence-anniversary publication dates official adoption to 17 January 1972. That date is distinct from the 31 October 1972 statutory order. [3] [1]
The 1971 predecessor carried a yellow map inside the red disc; that map was removed in 1972. It is a superseded design and should not be substituted for this current specimen. The government’s Teachers’ Portal recounts this change; it is educational history, rather than the adopting instrument. Teachers’ Portal account ↗
Symbolism
The High Commission in Kuala Lumpur associates green with vegetation and youthfulness, and the disc with the rising sun of independence after struggle. These are official explanatory interpretations, separate from the legal construction clauses. [4]
Usage
The Flag Rules regulate display on buildings, vehicles, and official occasions. Their published building sizes include 10 × 6, 5 × 3, and 2½ × 1½ feet, all stated fly first. These are prescribed sizes, rather than measurements inferred from photographs. [2]
A March 2026 government directive reiterates the national flag’s proportions and the requirement that no other flag fly above it. Consult current protocol instructions for a particular occasion; the older consolidated rules linked below are used here for construction, not as a complete current calendar of observances.

Record dates and evidence
The period begins on 17 January 1972, the adoption date reported in the Bangladesh Embassy’s 2019 independence-anniversary publication, printed page 11. This is distinct from the statutory order dated 31 October 1972. The original January adoption instrument was not located in the documented review.

Calculated construction example
The hoist is the attachment edge; fly length is the horizontal length from that edge to the opposite edge. A height-to-length ratio of 3:5 and a length-to-height ratio of 10:6 describe the same proportions: reversing 10:6 gives 6:10, which simplifies to 3:5.
For an illustrative flag 100 cm long and 60 cm high, applying the existing construction formula gives:
- Disc radius: 0.2 × 100 = 20 cm.
- Disc centre measured horizontally from the hoist: 0.45 × 100 = 45 cm.
- Disc centre measured vertically from the top: 0.3 × 100 = 30 cm.
This is a calculated, scaled illustration of the Second Schedule and Rule 3 geometry, not an additional prescribed manufacturing size.
Frequently Asked Questions
Is the red disc centred?
It is centred vertically but offset horizontally toward the hoist, the attachment edge. Its centre is 45% of the fly length from the hoist, rather than 50%, and halfway down the flag. In the 100 cm × 60 cm calculated example, that is 45 cm from the hoist and 30 cm from the top. The cited construction specifies the placement; no purpose for the offset is asserted here.
Are the displayed HEX values official colour standards?
No. Green #006747 and red #DA291C are specimen screen approximations from the selected SVG artwork. The cited legislation supplies a textile dye specification; it does not establish these HEX values as official equivalents. Screen colours cannot replace the physical textile specification. The imported artwork attribution and asset provenance remain applicable.
Does the current flag include a map?
No. The current design has a red disc on a green field without a map. The 1971 predecessor carried a yellow map inside the disc; the map was removed in 1972. The Teachers’ Portal account supports this historical distinction as educational history, not as the original adoption instrument.
