They are not usually found higher than 1200 meters above sea level. Lar gibbon are usually found in lowland dipterocarp forest, hill dipterocarp forest, and upper dipterocarp forest, including primary lowland and submontane rainforest, mixed deciduous bamboo forest, and seasonal evergreen forest. Lar gibbons are likely extinct in China, but if they still exist, they would only be found in southwest Yunnan, their former range. In recent decades, especially, the continental range has been reduced and fragmented. It is also present in the northwest portion of the island of Sumatra. Their range historically extended from southwest China to Thailand and Burma south to the whole Malay Peninsula in primary and secondary tropical rain forests.
