Frequently asked questions
Why is there no Garuda emblem in the document?
We do not distribute Garuda emblem images. The system leaves a 3 cm blank space at the top so you can print onto your agency's Garuda letterhead paper, or you can attach an emblem image file your agency is authorised to use. The image is only placed into the generated file and is not stored.
Which salutation goes with which closing?
For ordinary people, use "Rian" (Dear) with "Khosadaeng khwam napthue" (Yours faithfully). For high office holders such as the Prime Minister or the Speaker of Parliament, use "Krap rian" (Respectfully addressed to) with "Khosadaeng khwam napthue ying" (Yours most respectfully). For Buddhist monks, use "Namasakan" (Reverently addressed to) with "Khonamasakan duai khwam khaorop" (With reverent respect). The system chooses the closing to match the salutation. For other special cases, check the appendix of the official correspondence (Saraban) regulations.
What fonts and spacing are used in the document?
Word files use the TH SarabunPSK font at 16 pt, while PDFs use the Sarabun font sized to look as close as possible. The left margin is 3 cm, the right margin 2 cm, and paragraph indent 2.5 cm. If the letter runs longer than 1 page, later pages carry a page number at the top.
Is my letter data stored?
No. The text and any attached emblem image are used to generate the file and returned immediately. We only record an anonymous count of how many times the tool is used.
