Gross vs net square meters: why the apartment feels smaller
A 4-room “110 m²” on Yad2 looks, once inside, like an 85 m² flat in London or a 900 sq ft apartment in New York. It is not a scam, it is a different measuring convention, and it distorts every per-square-meter comparison for a buyer coming from abroad. Here is what the Israeli figure counts, what the law says, and how to bring a listing back to a real area.
The short answer
In Israel, the area stated in a listing is almost always a gross area (shetach bruto): the apartment’s footprint measured to the outside of the walls, interior and exterior walls included, most often with the balcony counted at 100%, and sometimes a share of the common areas (stairwell, lobby, plant room). The usable floor area, what a RICS or ANSI survey would measure, is 15 to 20% smaller: a property listed at 100 m² is generally 80 to 85 m² inside. For new builds, the Sale Law regulations have since 2008 defined the “apartment area” as walls included but balcony separate; for resales, no rule applies to the listing. Before signing, ask for the dimensioned plan (tochnit dira) and compare prices per m² on the net area.
The figures to remember, November 2026
- Gap gross → usable
- −15 to −20%
- 100 m² listed, inside
- 80–85 m²
- Walls as a share of gross
- ≈ 10–15%
- Typical balcony on a new 4-room
- 10–14 m²
What gross area counts, and what net area counts
Three areas coexist for the same apartment, and listings almost never say which one they use. One m² is 10.76 sq ft; a “100 m²” Israeli listing is 1,076 sq ft gross, about 860 to 915 sq ft usable.
| Area | What it includes | Where you find it |
|---|---|---|
| Gross (bruto) | External footprint, walls included, balcony at 100% or 50%, sometimes a share of common areas (up to +5-8%) | Yad2 listings, agencies, resale contracts |
| Apartment area (shetach dira, new builds) | Footprint measured to the outer faces of the walls, walls included; balcony, storage and parking stated separately | Specification (mifrat) of the developer’s contract, building permit |
| Net or usable (neto) | Floor area inside the walls, excluding balcony and common areas | Dimensioned plan, on-site measurement, shamai’s report |
Walls account for 10 to 15% of an Israeli apartment’s footprint, more in a recent building with a mamad (safe room with 25 to 40 cm concrete walls). The balcony adds 10 to 15% on a recent property. Together they explain the 15 to 20% gap between the listing figure and what you measure with a tape.
What the law says for new builds: the apartment area
For an off-plan purchase, the regulations under the Sale (Apartments) Law require the developer to attach a standardised specification (mifrat) to the contract, stating the apartment area under a single definition: the area bounded by the outer faces of the exterior walls, including interior walls and the mamad, excluding the balcony, terrace, storage and parking, which are listed separately with their own areas. The share of common areas is not part of it. A 2% tolerance is allowed between the promised and the delivered area; beyond it, the buyer is entitled to a price reduction or compensation.
Consequence: from a developer, a “4-room, 108 m² + 12 m² balcony” does mean 108 m² walls included, or about 92 to 95 m² of floor. Sales brochures, on the other hand, sometimes add everything up (120 m²). Only the mifrat figure is binding. The rest of the developer’s contract, and what a lawyer gets changed in it, is in buying off-plan from a developer.
Reading a Yad2 or Madlan listing
On resales, no law governs the listed area. The habits are as follows:
- Yad2: the “built area” field (shetach banui) is filled in by the seller or the agent, most often gross with the balcony included. The balcony field, when filled, is rarely deducted from the total.
- Madlan: the area often comes from the Tax Authority’s transaction data, which repeats the figure declared in the contract, itself gross. The prices per m² displayed are therefore gross prices per m².
- Agencies: “100 m² gross, 85 net” when the agent is precise; otherwise, ask.
- Arnona bill: the municipal area, specific to each city, useful as a cross-check.
The prices per m² by city published by the Central Bureau of Statistics and used in our price pages are computed on these declared areas. They serve to compare one city with another, not to judge a specific apartment: for that, you need the plan.
Example: a 4-room “100 m²” in Jerusalem
| Listed gross area (walls, balcony, no common share) | 100 m² |
| Balcony, counted at 100% in the listing | − 12 m² |
| Apartment area walls included (new-build definition) | 88 m² |
| Interior and exterior walls and mamad (≈ 12%) | − 10.5 m² |
| Net usable area | ≈ 77.5 m² / 834 sq ft (+ 12 m² balcony) |
| Price per m² on the listed area | ₪29,000/m² |
| Price per m² on the net area | ≈ ₪37,400/m² |
A buyer comparing this property with an 830 sq ft apartment in Manhattan or a 78 m² flat in London is therefore comparing equivalent areas, not 100 against 78. And two Israeli listings at ₪29,000/m² can hide a 20% real difference if one includes a share of common areas and the other does not. The purchase tax schedule, for its part, does not depend on area: see the purchase tax calculator.
Checking before you sign
- Ask for the dimensioned plan (tochnit dira), from the building permit or the condominium file. Your lawyer can obtain it from the municipality (tik binyan); it also reveals extensions built without a permit.
- Measure on site, or have the person viewing for you measure: length × width of each room, five minutes and a laser measure.
- Read the shamai’s report (licensed appraiser) if you take a mashkanta: it states the registered gross area and, often, the net area, and the bank computes the loan on its valuation.
- On a new build, check the mifrat: apartment area, balcony area, 2% tolerance, and have the lawyer add a price-reduction clause beyond it.
- Cross-check with the arnona bill and the nesach tabu (land registry extract), which sometimes states the registered area of the sub-plot.
These checks are part of the lawyer’s work before the heskem mechira (sale contract). What else they check, and what they cost, is in the real estate lawyer in Israel; the full sequence in how to buy property in Israel.
Frequently asked questions
Is there a legal measurement standard like RICS or ANSI in Israel?
Not for resales. No law requires a usable area in a listing or in a resale contract. Only new builds are regulated: the specification (mifrat) attached to the developer’s contract must state the apartment area under the regulatory definition, walls included and balconies separate. On a resale, it is up to the buyer to measure or have it measured.
Does the balcony count in the area?
In most resale listings, yes, often at 100%, sometimes at 50%. On a new build, the regulations require it to be stated separately from the apartment area. A 12 m² balcony on a “100 m²” property therefore accounts on its own for 12% of the gap between the listing and the interior.
Which area is used for arnona?
Each municipality has its own measuring method, generally gross area including walls, sometimes with a share of common areas, rarely the balcony. The arnona area appears on the annual bill and gives a useful order of magnitude, but it matches neither the listing nor the usable area.
How do I compare price per m² between two listings?
Bring each property back to net floor area: ask for the dimensioned plan, subtract the balcony and apply 85% for walls if the listing includes them. A 110 m² gross at ₪2.6M (₪23,600/m² gross) may be ₪29,000/m² net, while a 95 m² listed net at ₪2.5M is ₪26,300/m². Without this correction the ranking flips.
