Average Apartment Size in Singapore

Updated 28 August 2026 · HDB flat types + Urban Redevelopment Authority (URA) + SingStat

Typical Singapore home

84–90 m²

≈ 904–969 ft²

Roughly 80 percent of residents live in HDB flats; the most common, the 4-room, is about 90 m² (969 ft²). New private condos are smaller, with a median of 84 m² (904 ft²) in 2024 (URA). Much larger than Hong Kong (~40 m²).

Singapore is a dense, high-cost island city, but its homes are far more generous than Hong Kong’s because of its public-housing programme. Around eight in ten residents live in a flat built by the Housing & Development Board (HDB), and the most common of these is the 4-room flat at roughly 90 square metres. Private condominiums, home to the remaining fifth of residents, tend to be smaller for new launches, with a 2024 median of about 84 square metres.

HDB Flat Sizes by Type

HDB flats are quoted by room count. The figures below are approximate internal floor areas; newer Build-To-Order (BTO) flats sit at the smaller end of each band, while older resale flats can be a little larger.

HDB flat type	Approx m²	Approx ft²
2-room Flexi	38	409
3-room	65	700
4-room (most common)	90	969
5-room	110	1,184
3Gen	115	1,238

2-room Flexi flats come in 38 m² and 47 m² layouts. Source: HDB flat types. The 4-room flat houses close to a third of resident households (SingStat), making it the single most common home in Singapore.

2-room Flexi

~38 m²

Studio-style. 38 m² (Type 1) or 47 m² (Type 2). Aimed at singles and elderly.

3-room

~65 m²

Two bedrooms. Around 60 to 69 m² depending on generation.

4-room

~90 m²

Three bedrooms. The modal Singapore home and the single most common dwelling type.

5-room

Three bedrooms plus a larger living/dining area. Around 110 to 113 m².

Private Condominiums and Shoebox Units

The median new non-landed private home was 904 sq ft (about 84 m²) in 2024, according to the Urban Redevelopment Authority. New private apartments have been shrinking: the median has fallen about 11 percent since 2010, when it was 1,012 sq ft (about 94 m²).

·A shoebox apartment is a private unit of 50 m² (538 sq ft) or less, usually a studio or compact one-bedroom.
·Shoebox launches have collapsed: new shoebox sales fell to about 254 units in 2024, down roughly 91 percent from the 2012 peak.
·From 2023, URA required at least 20 percent of new Central Area units to be 70 m² or larger, part of a wider push to stop apartments shrinking further.

Frequently Asked Questions

What is the average apartment size in Singapore?

It depends on the housing type. Roughly 80 percent of Singapore residents live in HDB public-housing flats, and the most common is the 4-room flat at about 90 m2 (969 sq ft). New private condominiums are smaller: the median new non-landed private home was 904 sq ft (about 84 m2) in 2024, per the Urban Redevelopment Authority. So a typical Singapore home is around 84 to 90 m2, larger than Hong Kong (median about 40 m2) but smaller than the United States or Australia.

How big is a 4-room HDB flat?

A 4-room HDB flat is about 90 m2 (969 sq ft) and has three bedrooms. It is the most common home type in Singapore, housing close to a third of resident households. Newer Build-To-Order (BTO) 4-room flats sit near 90 m2; some older resale 4-room flats are slightly larger.

How big are the other HDB flat types?

A 2-room Flexi flat is about 38 m2 or 47 m2; a 3-room flat is roughly 60 to 69 m2; a 5-room flat is about 110 to 113 m2; and a 3Gen flat for multi-generational families is around 115 m2. Sizes vary between the older and newer generations of flats.

Are Singapore condos smaller than HDB flats?

Often, yes, for new launches. The median new non-landed private home was 904 sq ft (about 84 m2) in 2024, smaller than a 4-room HDB flat at about 90 m2. New private apartments have shrunk about 11 percent since 2010, when the median was 1,012 sq ft (about 94 m2), as developers built more compact units to keep headline prices affordable.

What is a shoebox apartment in Singapore?

A shoebox apartment is a private unit of 50 m2 (about 538 sq ft) or less, typically a studio or compact one-bedroom. Shoebox launches have fallen sharply: new shoebox sales dropped to about 254 units in 2024, down roughly 91 percent from the 2012 peak, partly because of rules that discourage very small units.

Has the government limited shrinking apartment sizes?

Yes. From 2023, the Urban Redevelopment Authority tightened rules so that new developments yield fewer, larger units, and required that at least 20 percent of new units in the Central Area have a net internal area of at least 70 m2. These measures were introduced to stop private apartments shrinking further.

How does Singapore compare to Hong Kong?

Singapore homes are considerably larger. Singapore's typical home is 84 to 90 m2 (HDB 4-room 90 m2; new private median 84 m2), while Hong Kong's median home is around 40 m2 saleable area. Both are dense, high-cost island cities, but Singapore's public-housing programme delivers much more floor space per household.
