Outline of Koh Tao
The outline is fitted to this frame, not a map for measuring distances. Outlying islands may make the main landmass appear smaller.

Scope and definitions

Physical Koh Tao area paired with the 2024 Ko Tao subdistrict registered population. The administrative subdistrict also covers very small nearby islands, so density is a close local approximation rather than a headcount confined to the coastline.

Average administrative density does not describe population distribution in every neighborhood. Compare population definitions and reference dates alongside the numbers.

Place guide

How should this Koh Tao profile be read?

Koh Tao is a compact island with a local subdistrict population that can be separated from the wider Ko Pha-ngan District.

A close but not perfect island boundary

The area is for the physical main island. Ko Tao subdistrict can include tiny nearby islands, so the registered-population density remains a close approximation.

This limitation is much smaller than using the full two-island district total.

Use the island as a small-scale reference

Its area sits close enough to Green Island for a useful direct comparison and far below the larger Gulf islands.

Tourism intensity requires visitor and accommodation data beyond registered residents.
