[5] The reigning Miss Grand Thailand is Malin Chara-anan of Phuket who was crowned on 6 April 2024 at the MGI Hall, Bravo BKK Mall in Bangkok.

[17][18] Under Channel 7, the pageant had the most popular viewership on Thai TV, compared to its rival, Miss Universe Thailand.

[27][28] The provincial winners are titled "Miss Grand (Province)", and are not permitted to participate in any beauty pageants without the organization's consent.

[33][34] Obdam was elected by the organization to compete at Miss Tourism Metropolitan International 2016 in Cambodia, where she won the title.

The ancillary activities usually consist of three sub-events: the best in swimsuit competition, darling of the host round, and the national costume parade.

[49][50][51] These activities are arranged in the preliminary host provinces (e.g. 2013 in Pattani[52] and 2014 in Buriram[2]) except the national costume parade which is held at the final competition venue.

During 2013 – 2018, all quarterfinalists were chosen from the initial pool of delegates through a closed-door interview, swimsuit round, and the preliminary competition, then the judges selected the ten semi-finalists as well as the five finalists based on their performances on the final stage, as usually done in other pageants.

Usually, the Miss Grand Thailand finalists are granted the right to participate in various international contests affiliated with the organization.

[154] It arose from the meticulous regulations of Miss Grand Thailand Ltd., the provincial title holders are not permitted to participate in any beauty pageants throughout the year of reign unless with the organization's consent.

[154][29][30] Moreover, if the investigation found the director's involvement in such an offense or failure to comply with the contract-specified terms and conditions, the provincial licenses might additionally be terminated.

Therefore, the competition result was not authenticated and the license was transferred to another organizer, who held the substituted contest to elect the replacement later in Bangkok.

[154][159][156] Following the national contest completion, the Phatthalung titleholder has subsequently been removed from the provincial title in late November as a result of taking part in the Miss International 2017 pageant in Japan without informing the organization.

[155] As well, the candidates from Ang Thong, Amnat Charoen, Nong Khai, Phang Nga, and Mae Hong Son were also relieved from the title after taking part in other local pageants during their reign.

[160] In the 2018 season, two provincial title holders were dismissed and received a permanent prohibition to engage in any exhibition related to Miss Grand Thailand Ltd. when the representatives of Yasothon and Lampang province participated in other contests without completing the year of reign.
