As you might have found already, the information about what photo size is required when applying for Thai visa might be confusing. Let us to make this question clear as the required Thailand visa photo size depends on the type of visa you are planning to apply for because visa application forms used are different. These photo specifications are valid in 2020!
Thailand Visa Photo Size at Thai Embassy/Consulate
When applying for Single-Entry Tourist Visa, Multiple-Entry Tourist Visa, Transit Visa or any Non-Immigrant Visa at one of Thai embassies or consulates worldwide, the required Thailand visa photo size is 3.5 cm x 4.5 cm.
This Thai visa photo specification is set by the size of the field on the application form as 3.5 cm x 4.5 cm is the photo size that will perfectly fit on the usual Thailand Visa Application Form.
Depending on the embassy/consulate, you will need to submit one or two photos of 3.5 cm x 4.5 cm size. In some cases some of nationalities need to submit more than 2 photos when applying not in their home countries but all this information can be found on the website of the specific Thai embassy or consulate.
The visa photo should be not older than 6 months.
Thailand Visa Photo Size on Arrival
Tourists from India, China and 16 other countries who are planning to apply for Thailand Visa on Arrival at the airport or border crossing need to provide larger size visa photo to the Immigration officer. The required Thailand visa photo size on arrival is 4.0 cm x 6.0 cm.
When applying for Thai Visa on Arrival, you will need to fill Thailand Visa on Arrival Form and attach one photo of 4.0 cm x 6.0 cm size as the space dedicated for attaching the photo to the form is that sized.
Visa photo size 4.0 cm x 6.0 cm should also be used for attaching to Thai visa extension application form when applying for Thailand Visa Extension.
Only one 4.0 cm x 6.0 cm size photo is required when applying for Thai Visa on Arrival or Thai Visa Extension.
In these cases the visa photo should also be not older than 6 months.
Where to make Thailand Visa photo?
At the airports in Thailand, where they are issuing Thailand Visa on Arrival, you can normally find a photo booth (at least at the largest ones) and get your photos done in few minutes for about 200 THB. On land border crossings finding such a service can be difficult.
When applying for Thai Visa Extension at Thailand Immigration Office in Bangkok, photos can also be made at the place. Situation might be less convenient at the smaller immigration offices around the country.
Thai embassies and consulates don’t provide photo service by themselves but it’s easy to find someone making them around the most popular ones such as Thai Embassy in Vientiane. In most cases it’s best to get your photos done in advance.
The best visa photo will not help you to get your Thai visa if your visa application form will not be filled out correctly. For detailed information about filling different Thai visa application forms check:
