Physical Geography Anchors
SingStat and URA anchors for Singapore's land area, coordinates, island dimensions, relief, low-lying exposure, and terrain zones — with dated land area and reclamation caveats.
Physical Geography Anchors
Land area is a measured quantity that changes with land reclamation and cadastral surveys. Canonical headline figure also in key statistics.
Location and dimensions
| Anchor | Value | As-of / note |
|---|---|---|
| Latitude | 1°09′–1°29′ N | Main island extent |
| Longitude | 103°36′–104°25′ E | Main island extent |
| Distance north of Equator | About 137 km | SingStat environment reference |
| Main island length (E–W) | About 49 km | |
| Main island width (N–S) | About 28 km | |
| Land area | 744.3 km² | Dec 2025; 2.515 m High Water Mark cadastral boundary (preliminary when first released) |

Relief and terrain zones
| Anchor | Value | Note |
|---|---|---|
| Highest natural point | Bukit Timah Hill — 164 m | |
| Typical elevation | Much of island within 15 m of sea level | |
| Land below 5 m amsl | About 30% of land area | Coastal-flood exposure context |
| Granite central hills | Bukit Timah, Bukit Panjang, Mandai, Bukit Batok | SingStat terrain grouping |
| Western ridges | Mount Faber, Pasir Panjang ridges | Undulating western zone |
| Eastern coastal plain | Alluvium/sediment through Katong, Bedok, Changi |

Retrieval guardrails
| Confusion | Correct distinction |
|---|---|
| Timeless land area | Always cite measurement date; reclamation changes shoreline |
| 734 km² vs 744.3 km² | Different reference dates — use latest SingStat with date |
| Physical geography = climate forecast | Climatology lives in climate normals anchors and physical geography and climate |
| Main island = only offshore feature | Jurong Island amalgamation; Pulau Ubin, Tekong etc. — see offshore islands |
