Island size: 228.7 km2 vs 247 km2 (source discrepancy)
Reviewed by the Samui Local Hub team ·
Fact
Two different area figures circulate for Koh Samui. Wikipedia and the Tourism Authority of Thailand (TAT) quote 228.7 square kilometres. Older tourism texts (Wikitravel, Thaiways Magazine, several tour companies) quote 247 square kilometres. The 228.7 km2 figure is used by current official-adjacent sources and is recommended; the 247 km2 figure appears to be an older or rounded alternative (possibly including small offshore islets). Both are recorded here.
