Who knew Oahu and London were the same sizes!? Koh Samui is just 14.80% the size of Oahu, and 14.55% the size of London

Koh Samui is most definitely not bigger than other well-known islands like Fiji, Phuket, Oahu, PEI and Tasmania. In fact, dropped elsewhere, you might have to squint to find it. Yep, Koh Samui is dwarfed in size by pretty much any island you'd care to name – its ring road is 51 kilometres long, meaning you can easily drive around it in an afternoon.

But size isn't everything, is it boys?

Though Koh Samui's svelte proportions measure just 10 or 15 kilometres wide – a total of 228.7 sq km – don't assume this means it's a desert island with nothing to do. Not so. There's tons to do here – look no further than The Koh Samui Guide to fill your days (and your stomach). All the more reason to leave a cold country and try out this very big small island, ASAP!
