How to Compare Apartment Sizes in Square Meters and Square Feet

You've found two apartments that look similar in the photos. One listing says 65 m². The other says 750 sq ft. You need to know if they're actually the same size or if one is significantly larger than the other.

This is a genuine comparison problem. Most countries use square meters (m²), but the US, Canada, and a few others use square feet (ft²). If you're relocating internationally, comparing listings across borders, or just trying to decode what a foreign listing actually means, you need a fast conversion.

Use the Area Converter to convert any area value instantly. This article walks through the practical side — what common sizes look like in both units, how to develop intuition for both systems, and how to compare listings fairly.

The Conversion: Square Meters to Square Feet

The exact conversion factor:

1 square meter = 10.764 square feet

Going the other direction:

1 square foot = 0.0929 square meters

The quick mental shortcut: multiply square meters by 10.75 to get square feet, or divide square feet by 10.75 to get square meters. This is accurate enough for real estate comparisons.

So to answer the opening question: 65 m² is 700 ft², and 750 sq ft is 70 m². If one listing says 65 m² and another says 750 sq ft, the second apartment is slightly larger by about 5 m² (50 ft²).

What Common Apartment Sizes Actually Feel Like

It helps to anchor the numbers to real spaces. Here's a rough breakdown:

Studio / efficiency (25–40 m² / 270–430 ft²)

This is a single open room with a kitchen area, a bathroom, and enough floor space for a bed and a small sofa — but not much more. In major cities, a 30 m² studio often functions fine for one person who keeps the space tidy. It's tight for two people or for anyone who works from home.

One-bedroom apartment (40–65 m² / 430–700 ft²)

A proper one-bedroom has a separate sleeping room. At the low end (40 m²), the living room is small and storage is limited. At 65 m², there's typically room for a real sofa, a dining table, and enough kitchen counter space to cook actual meals. In European cities, 55–60 m² is a comfortable one-bedroom for one or two people.

Two-bedroom apartment (65–100 m² / 700–1,075 ft²)

Two bedrooms with a shared living room and kitchen. At 70 m², both bedrooms are workable but not large. At 90–100 m², there's room for a proper dining area and some storage. A 100 m² two-bedroom in Paris or Berlin would be considered spacious; in an American suburb, it's on the smaller side.

Three-bedroom apartment or townhouse (100–150 m² / 1,075–1,615 ft²)

Comfortable for a family. Three proper bedrooms, a reasonable living area, and enough kitchen space to be functional. At 120 m², this is a generous European flat. In the US, 1,200 sq ft (111 m²) for a three-bedroom is considered compact.

Large family home (150–250 m² / 1,615–2,690 ft²)

The gap between European and American space expectations becomes visible here. A 200 m² (2,150 ft²) house is exceptional in most of Europe; in the American suburbs, it's close to the national average for a single-family home.

Why Listings in the Same City Can Have Different "Feel"

Square meters or feet measure the floor area — but what's included in that number varies.

In most European real estate markets, the listed area is the "net floor area" or "usable area" — the space you can actually stand and walk in, excluding walls, stairwells, and sometimes balconies. In some markets (Germany's Wohnfläche standard, for example), even areas with low ceilings may be partially excluded.

In the US, "gross living area" (GLA) is the standard used by appraisers — this includes all finished, above-grade living space, including staircase landings. Some listings also include unfinished basement area in the total, which inflates the number.

In New York City, listings sometimes include the thickness of the walls in the square footage, making two apartments with the same listed area actually different in livable space.

The practical result: a 70 m² apartment in Berlin may feel more spacious than a 70 m² apartment listed in a country that uses a more generous measurement convention. When comparing internationally, square footage is the start of the comparison, not the end.

How to Get a True Size Comparison

When looking at listings across different countries, a few extra checks help:

Check what's included. Does the listed area include the balcony? Basement storage? Parking? In some French listings, the "surface habitable" excludes the balcony, which adds 10–15 m² in many Parisian apartments but isn't counted. In other markets, balconies are always included.

Ask for a floor plan. A floor plan shows room dimensions, and you can check whether the listed total area makes sense given the room layout. If the floor plan shows rooms that seem larger than the total area would suggest, something is off.

Use a reference point you know. If you've lived in a 70 m² apartment before, use that as your anchor. A 65 m² apartment will feel slightly tighter; an 85 m² apartment will feel noticeably roomier. Most people have a good intuition for relative size once they have a personal reference point.

Convert everything to the same unit. If you're comparing five listings, convert them all to either m² or ft² using the Area Converter and sort by size. That removes the cognitive load of keeping two systems in mind simultaneously.

Useful Benchmarks for International Comparisons

Average apartment sizes vary widely by country. Some reference points:

• Average new apartment, Germany: ~75–80 m² (807–861 ft²)
• Average new apartment, UK: ~67 m² (721 ft²)
• Average new apartment, France: ~66 m² (710 ft²)
• Average US apartment (all types): ~107 m² (1,150 ft²)
• Average new apartment, Japan (Tokyo): ~35–45 m² (377–484 ft²)
• Average apartment, Hong Kong: ~42 m² (452 ft²)
• Average new apartment, Australia: ~135 m² (1,453 ft²)

These averages tell you something about what "a normal apartment" means in each country. An 80 m² apartment in Tokyo is very large; in Sydney, it's on the small side.

A Note on Ceiling Height and Volume

Two apartments with identical floor area can feel completely different based on ceiling height. A 60 m² apartment with 3-meter ceilings has 180 m³ of space. The same apartment with 2.4-meter ceilings has 144 m³ — 20% less volume even though the floor area is identical.

Older European buildings — from the late 19th and early 20th century — often have ceiling heights of 3–3.5 meters, which makes the same m² feel significantly more open than a modern building with 2.4-meter ceilings. If ceiling height is listed in a property description, pay attention to it. For rooms where you spend a lot of time, it matters as much as the floor area.

The Area Converter handles any area value — not just apartments. If you need to compare a garden, a terrace, a commercial space, or a land plot, the same conversion applies.
