Thailand's national flag bears the official name Thong Trairong (ธงไตรรงค์). English speakers translate that directly as "tricolor flag." It serves as the core symbol for the Kingdom of Thailand today. The Thailand flag stacks five horizontal stripes from top to bottom. The color Thailand flag is red, white, blue, white, and red precisely. The middle blue stripe doubles the width of all others.
King Vajiravudh (Rama VI) launched the design for official use on September 28, 1917. The Flag Act of 1979 locked it in as the national flag Thailand flies everywhere. Official specifications define the flag’s proportions as 2: 3. The blue color claims two units wide, while red and white take one each in the national flag Thailand. Cultural views link colors to nation, religion, and monarchy without legal force.

Design and Layout of the Thailand Flag
The flag was officially adopted in 1917 and later codified in the Flag Act of 1979, which reaffirmed its specifications and usage. The table below summarizes the main technical parameters.
| Aspect | Specification |
|---|---|
| Orientation | Horizontal stripes, hoist vertical, fly horizontal |
| Color of Thailand flag | Red, white, and blue in five-stripe sequence |
| Digital colors | Red: RGB(165,25,49), HEX #A51931; White: RGB(244,245,248), HEX #F4F5F8; Blue: RGB(45,42,74), HEX #2D2A4A |
| Print the color of Thailand flag | Red: CMYK(24,100,83,18); White: CMYK(3,2,1,0); Blue: CMYK(39,43,0,71) |
| Color arrangement | Red-white-blue-white-red horizontal sequence from top to bottom |
| Emblem placement | No emblem on civil flag; naval ensign includes red disc with white elephant |
| Official proportions | 2:3 ratio; central blue stripe width equals 2 parts, and the other stripes 1 part each |
Some modern references provide standardized digital color approximations for the Thai flag, especially in commemorative and design contexts, though official legislation focuses mainly on layout and proportions. The proportions divide the flag's height into six equal parts, allocating one part each to the outer red and white stripes and two parts to the central blue stripe.
Flag of Thailand: Meaning and Symbolism
Standard academic and reference works show that different sources have different ideas about what Thailand's flag means. Cultural interpretations of its colors and proportions vary significantly depending on the source. The article explains the meaning of Thailand flag by highlighting the symbolism behind its red, white, and blue stripes.
Many sources tie the three colors to Thailand's motto "Nation, Religion, Monarchy" (Chat, Satsana, Phra Maha Kasat). They frame these as popular views, not locked-in legal meanings.
Red evokes the Thai nation and its people in frequent accounts. White signals religious purity, especially Theravada Buddhism, among most citizens. Blue represents the constitutional monarchy boldly.
Thailand swapped to blue, white, and red in 1917 to match World War I Allies like France, Britain, the U.S., and Russia. Earlier versions of the elephant flag receive their own historical treatment, separate from today's design.
Government offices more commonly use indoor flag stands for events than permanent outdoor displays. Shopping hubs and homes skip routine displays except on holidays. Royal occasions spark waves of temporary flags across commercial streets.
What the Thailand Flag Represents
- The red stripes on the Thailand flag commonly represent the Thai nation and the unity of its people across ethnic groups.
- Reference sources often describe the white stripes as symbolizing religious purity, particularly the role of Buddhism in Thai culture and daily life.
- Many cite the blue central stripe as a symbol of the constitutional monarchy and its historical significance to Thai national identity.
- Historical contexts note that the tricolor arrangement reflects Thailand's diplomatic alignment with Western Allied powers during the early 20th century.
How to Identify the Flag of Thailand
At airports, international terminals, and border-control signage, the Thai flag often appears among rows of national flags, next to country codes showing TH or THA and maps indicating where Thailand is in Southeast Asia. Public transport maps and information counters may show the design as a visual indicator for Thailand-operated services.
- Look for five horizontal stripes arranged symmetrically with red on top and bottom, white stripes adjacent to the center, and a blue central stripe twice the width of the others.
- Confirm the flag displays no emblems, stars, or symbols on the civil version, distinguishing it from the naval ensign, which includes a white elephant on a red disc.
- Verify the color sequence runs red-white-blue-white-red from top to bottom, with the blue stripe occupying the middle position.
- Because of its symmetrical stripe pattern, the Thai flag generally appears the same even if inverted, which was one reason for adopting the design.

History of the Flag of Thailand
The history of Thailand flag traces multiple designs back to the Ayutthaya period, though systematic documentation increases during the Rattanakosin era beginning in 1782.
- In 1782, the early Rattanakosin period introduced a plain red flag as a simple national identifier for Thai vessels and state facilities.
- Between 1782 and 1817, a white chakra symbol was added to the plain red field to distinguish Thai ships in regional waters.
- In 1817, King Rama II placed a white elephant within the chakra, creating what became known as the "Elephant Flag," which remained in use until 1916.
- In 1855, King Rama IV simplified the design by removing the chakra and enlarging the white elephant against the red field to improve visibility at sea.
- In 1916, King Rama VI replaced the elephant with horizontal red and white stripes to create a symmetrical design that would not appear incorrect when displayed upside down.
- On September 28, 1917, the central red stripe was changed to blue, creating the current Thailand flag design, which was formally codified through the Flag Act of 1979.
