Net vs Gross Square Metres in Turkey: How to Compare Apartment Sizes Before Buying
Buying Property in Turkey Near Metro Stations: Investment Guide
When searching for property for sale in Turkey, international buyers often compare apartments by price, location and the number of bedrooms. However, one important detail can easily be overlooked: the difference between net and gross square metres.
Two apartments advertised as having the same area may offer noticeably different amounts of usable living space. This can affect everyday comfort, the way a property is furnished, its suitability for long-term tenants and the value buyers believe they are receiving.
Understanding how apartment areas are measured in Turkey can help buyers make more informed comparisons, particularly when evaluating several residential projects in Istanbul.
In this guide, we explain the difference between net and gross area, what to check in property documents, how to compare apartments fairly and why advertised square metres should never be the only factor in a buying decision.
What Is Net Area in Turkish Property?
Net area generally refers to the usable internal floor area of an apartment. It is the space available for everyday activities, such as sleeping, cooking, relaxing and working.
Depending on the measurement method and the applicable documentation, certain elements may be excluded from the stated net area. Buyers should therefore ask exactly how the figure has been calculated rather than relying on the label alone.
When comparing apartments, pay attention to the actual dimensions of:
Living rooms and dining areas
Bedrooms and wardrobes
Kitchens and storage areas
Bathrooms and internal circulation space
Balconies, terraces and other external areas, where applicable
For example, an apartment advertised with two bedrooms may have a relatively large total area but a compact living room or limited storage. The layout can be just as important as the headline figure.
What Does Gross Area Mean?
Gross area is a broader measurement that may include elements beyond the apartment's usable internal space. Depending on the project, the measurement convention and the documents used, it may account for wall thicknesses or allocated portions of shared building areas.
There is no substitute for checking the actual definition used in a particular listing or project document. Buyers should not assume that every developer calculates gross area in exactly the same way.
This distinction becomes especially important when comparing apartments in different buildings. A larger advertised gross area does not automatically mean that the apartment provides more usable living space.
Net vs Gross Area: Why the Difference Matters
Consider two hypothetical apartments with the same advertised gross area.
Apartment A offers a more efficient layout, with a spacious living area and well-proportioned bedrooms. Apartment B has a larger share of its stated area associated with walls, circulation or other elements that do not translate into the same amount of usable internal space.
Although their advertised areas may look similar, the apartments can feel very different when viewed in person.
The lesson is simple: compare the documented area, the internal layout and the actual room dimensions together.
For international buyers exploring property for sale in Turkey, this is a useful first step before narrowing down a shortlist.
How to Compare the Price per Square Metre
Price per square metre is a common way to compare properties, but the calculation is only meaningful when the areas being compared use a consistent measurement basis.
A basic calculation is:
Price per square metre = Purchase price ÷ stated area
Imagine two hypothetical apartments:
Apartment A costs $240,000 and has a stated area of 80 m².
Apartment B costs $270,000 and has a stated area of 90 m².
Using the stated areas, Apartment A costs $3,000 per m², while Apartment B costs $3,000 per m² as well.
However, this comparison does not establish that the properties offer equal value. Their net areas, room layouts, locations, building facilities, completion status and ongoing costs may differ.
Before comparing prices, confirm whether each figure refers to net area, gross area or another measurement.
Five Questions to Ask Before Buying an Apartment in Turkey
1. Is the advertised area net or gross?
Ask the seller or property consultant to identify the measurement clearly in writing. If the listing uses both figures, request the supporting floor plan or technical documentation.
2. Can you see the floor plan with dimensions?
A floor plan helps you understand how the space is distributed. Look beyond the number of bedrooms and check whether the living areas, bathrooms and storage spaces meet your needs.
3. Are balconies and terraces included?
Outdoor spaces can add considerable lifestyle value, especially in Istanbul. However, their inclusion in an advertised area depends on the measurement convention. Ask for a breakdown rather than assuming they are counted consistently.
4. Does the documented area match the property being sold?
Where possible, compare the sales documentation, approved plans and relevant title-deed or technical records. If the figures conflict, seek clarification from an independent qualified professional before committing.
5. Are you comparing similar property types?
A compact city-centre residence should not automatically be compared with a family apartment or villa using only the price per square metre. Different property types serve different purposes and may attract different buyers and tenants.

Why Apartment Layout Matters for Rental Demand
The usefulness of an apartment is not determined by floor area alone. Layout, natural light, storage, access to transport and the surrounding neighbourhood can all influence how attractive a property may be to potential tenants.
A well-planned apartment may make better use of its internal space than a larger apartment with an inefficient layout. However, rental demand depends on several factors, and no floor-plan feature guarantees a particular rental return.
Investors should also consider the likely tenant profile. A single professional, a couple and a family may have different expectations regarding bedrooms, storage, outdoor space and proximity to everyday amenities.
If rental income is part of your investment plan, read our guide on how to calculate rental yield before buying property in Turkey. It explains why the purchase price alone is not enough to assess a property's financial performance.
Comparing Apartment Sizes Across Istanbul
Istanbul offers a broad range of residential options, from compact city apartments to larger family homes and premium residences. The most suitable choice depends on the buyer's budget, lifestyle and investment objectives.
For example, buyers comparing central districts with suburban residential areas may find different combinations of apartment size, building facilities, transport connections and local amenities.
Rather than choosing a district based on square metres alone, compare the actual apartment layout alongside its location and intended use.
You can explore current options through our Istanbul property listings.
The following examples provide different starting points for comparison:
Küçükçekmece Lakefront Residences — review the available apartment layouts and documented areas.
Atakent Park Residences — compare room proportions, apartment configurations and location.
Fulya Modern Residences — consider how the layout and location fit your intended use.
Availability, specifications and prices can change. Always check the individual listing and request current documentation before making a decision.
Does a Larger Apartment Always Offer Better Value?
Not necessarily.
A larger apartment may be the right choice for a family or a buyer who needs extra rooms. A smaller, well-designed apartment may suit someone who prioritises location, ease of maintenance or access to public transport.
The better comparison considers:
Verified net and gross area definitions
Purchase price and total acquisition costs
Room dimensions and layout efficiency
Location and transport access
Building quality and ongoing charges
Likely resale audience and intended use
There is no universally best size. The right property is the one that meets your requirements at a price you can justify after reviewing the relevant information.
What Documents Should Foreign Buyers Request?
Before signing a contract or paying a deposit, ask for the documents needed to verify the property's characteristics and legal status. Depending on the transaction, these may include the floor plan, relevant building and occupancy documentation, title-deed information and the sales agreement.
If the stated apartment area differs between documents, do not rely on a verbal explanation alone. Ask the responsible parties to clarify the discrepancy and obtain independent legal or technical advice where necessary.

Frequently Asked Questions
What is the difference between net and gross square metres in Turkey?
Net area generally refers to usable internal space, while gross area may include additional elements such as walls or allocated shared areas. The exact definition can vary, so buyers should verify the measurement basis used in each property listing and its supporting documents.
Is net area more important than gross area?
For understanding usable living space, net area is particularly useful. However, buyers should also review the floor plan, room dimensions, building features, location and relevant documentation before deciding.
How do I calculate the price per square metre of a Turkish apartment?
Divide the purchase price by the stated area. For meaningful comparisons, use the same area definition for every property and verify whether the figures represent net or gross area.
Should I trust the area shown in an online property listing?
Treat it as a starting point rather than the final verification. Ask for the relevant floor plan and supporting documents, and clarify discrepancies before signing an agreement.
Can two apartments with the same area have different values?
Yes. Layout, location, building quality, natural light, facilities, ongoing costs and potential buyer or tenant demand can all affect how properties compare.
Final Thoughts
When buying property in Turkey, square metres are important, but the way those square metres are measured matters just as much.
Understanding net and gross area helps international buyers compare apartments more consistently, identify questions that need clarification and avoid choosing a property based only on an advertised number.
Before making a shortlist, review the layout, confirm the measurement basis and compare the total cost with the property's location and intended use.
