Radius Map of Singapore

The map above is centered on Singapore, Singapore, near Merlion Park (Marina Bay), with a default 10 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.

Singapore is a city-state — an island nation about 50 km east-west and 27 km north-south. The Johor Strait separates it from Malaysia to the north, the Singapore Strait from Indonesia to the south. Distances here are measured from Merlion Park / Marina Bay (1.287° N, 103.855° E), the symbolic centre.

Population: Singapore (whole country)
Country: Singapore
Coordinates: 1.2868, 103.8545
Time zone: Asia/Singapore

Singapore is so small that a 25 km radius from Marina Bay covers the entire country plus parts of Malaysia (Johor Bahru) — it's the only major city where a single radius can cover the whole sovereign nation.

How Singapore radius maps get used

City-specific scenarios where a radius is the right tool — and the typical radius sizes professionals use.

CBD condo and rental search

A 3 km radius from Marina Bay covers the CBD, Orchard fringe, Bugis, Tanjong Pagar, and the central condo market — Singapore's most expensive and densest residential area. A 5 km radius adds the inner heartland districts.

Typical radius: 3 km for CBD condos

MRT-station catchment

Singapore's MRT network covers virtually the entire island, with most residential areas within 1 km of a station. For property analysis, a 1 km radius from any MRT station is a strong walkability signal; a 10 km radius from Marina Bay covers most of the central MRT lines.

Typical radius: 1 km MRT-station walkability + 10 km central MRT

Changi Airport service zone

Changi Airport sits ~17 km east of Marina Bay. A 20 km radius covers Changi plus the eastern heartland (Tampines, Bedok, Pasir Ris). The MRT East-West Line connects Changi to the CBD in about 35 minutes.

Typical radius: 20 km to include Changi and eastern districts

SIJORI cross-border catchment

For analyses crossing into Johor (Malaysia) and Batam (Indonesia) — the SIJORI growth triangle — a 50 km radius from Singapore captures the inner ring: Johor Bahru, Senai, Kulai, Batam. Border crossings (Causeway and Tuas Second Link) are the binding constraints.

Typical radius: 50 km for inner SIJORI cross-border

Geographic quirks of Singapore radius mapping

Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.

A 25 km radius covers an entire country

Singapore's land area is about 735 km². A 25 km radius from Marina Bay covers the entire island and reaches into Malaysia. This is unique among major cities — Singapore is the only sovereign nation where a single 25 km circle from the centre captures every inhabitant.

Sea on three sides, but causeways to Malaysia

Singapore Strait is south, Johor Strait is north, and the Singapore-Malaysia Causeway and the Tuas Second Link are the only road crossings. A radius "covers" Johor Bahru geographically but border-crossing time at peak (often 1–2 hours) is the real constraint.

The whole city is within 30 km

No point on Singapore island is more than about 27 km from Marina Bay. This makes Singapore the most "scale-invariant" major city for radius analysis — unlike sprawling metros like Tokyo or LA, where you have to choose carefully which centre point to use.

FAQ — Radius mapping in Singapore

How big is a 10 km radius in Singapore?

A 10 km radius from Marina Bay covers most of central and central-east Singapore — the CBD, Orchard, Bishan, Toa Payoh, Geylang, Bedok's western edge, Bukit Timah, and Holland Village. Changi Airport, Jurong, and Woodlands are just outside.

What's within 25 km of Singapore?

A 25 km radius from Marina Bay covers the entire island of Singapore — every district, Changi Airport, Tuas, Woodlands, Jurong — plus most of Johor Bahru, Malaysia across the Causeway. It's the smallest single radius that captures all of Singapore.

Does a 20 km radius cover Singapore Changi Airport (SIN)?

Yes. Changi Airport sits about 17 km east of Marina Bay, comfortably inside a 20 km radius. A 15 km radius does not reach Changi.

How far is Johor Bahru from Singapore?

Johor Bahru, Malaysia sits about 22 km north of Marina Bay across the Causeway — just inside a 25 km radius. Border-crossing time at the Woodlands and Tuas checkpoints can range from 15 minutes off-peak to 2+ hours during weekend rush.

Why can a Singapore radius cover an entire country?

Because Singapore is a city-state — an island nation about 50 km east-west and 27 km north-south, with a total area of 735 km². No other sovereign country fits inside a 30 km radius. The next-smallest major countries (Vatican, Monaco, Liechtenstein) are city-sized too but lack a major metropolitan economy.

How do I plan an MRT-station catchment in Singapore?

Singapore's MRT network covers virtually all populated areas of the island. For property or retail analysis, a 1 km radius from any MRT station typically captures the walkable catchment. For broader analysis, a 10 km radius from Marina Bay covers most central MRT lines, and a 25 km radius covers all of Singapore including the most peripheral lines.
