One Name, Several Meanings
Ask a farmer in Tel Aviv, a land buyer in Amman, and a property developer in Nicosia what a "dunam" measures, and you'll likely get the same answer: 1,000 square meters. But beneath this modern consensus lies a history of regional variation — and some important practical differences that still affect how land is measured, recorded, and transacted today.
Country-by-Country Overview
Israel
Israel uses the metric dunam of exactly 1,000 square meters — standardized during the British Mandate in 1928 and maintained ever since. The dunam is the de facto standard in all official land documents, Tabu registry entries, and real estate listings. Importantly:
- All ILA (Israel Land Authority) documents use dunams
- Agricultural water quotas are allocated by dunam
- Planning and zoning documents specify allowable construction in dunams or fractions thereof
Jordan
Jordan also standardized to the 1,000 sq meter dunam, and it is the official unit in Jordanian land law and the Land Registration Department. The Jordanian dunam is explicitly defined in the Land Registration Law. In rural areas, especially the Jordan Valley and highland agricultural regions, land transactions are routinely quoted in dunams.
Palestinian Authority (West Bank & Gaza)
Palestinian land records present a layered complexity. Records may exist under:
- Ottoman-era registrations (pre-metric dunams, ~919–940 sq m)
- British Mandate-era registrations (1,000 sq m metric)
- Jordanian-period registrations in the West Bank (1,000 sq m)
- Egyptian-period records in Gaza
For modern transactions under Palestinian Authority jurisdiction, the 1,000 sq meter standard applies, but verifying historical records often requires careful source-checking.
Turkey
Turkey's dönüm was historically defined at approximately 919.3 square meters under the Ottoman system. However, Turkey adopted the metric system in the 20th century, and the modern Turkish dönüm is officially 1,000 square meters. That said:
- Older property deeds may still reference the Ottoman dönüm
- In practice, many Turkish landowners and professionals informally use both figures
- The official Turkish unit of land in cadastral records is the decare (1,000 sq m), which equals the modern dönüm
Lebanon
Lebanon uses the dunam (locally spelled dounam or dunm), and the standard is 1,000 square meters. Lebanese real estate listings frequently cite dunams for land outside urban areas. However, within central Beirut and major cities, square meters are the more common reference unit.
Cyprus
Cyprus presents a unique case. The northern part of Cyprus (under Turkish Cypriot administration) uses the dunam in land records inherited from Ottoman administration, standardized to 1,000 sq m. The Republic of Cyprus (southern) primarily uses the square meter and hectare in official records, though historical deeds may reference the donum.
Iraq
Iraq is the major exception in the region. The Iraqi dunam (also called meshara in some contexts) has historically been defined as 2,500 square meters — considerably larger than the metric standard used elsewhere. This reflects a distinct Ottoman provincial tradition in Mesopotamia. Anyone dealing with Iraqi agricultural land in particular should be aware of this significant difference.
Summary Comparison Table
| Country | Dunam (sq meters) | Official Standard? |
|---|---|---|
| Israel | 1,000 | Yes — metric standard |
| Jordan | 1,000 | Yes — Land Registration Law |
| Palestinian Authority | 1,000 (modern) | Yes, with historical caveats |
| Turkey | 1,000 | Yes — modern metric dönüm |
| Lebanon | 1,000 | Commonly used, informal |
| Cyprus (North) | 1,000 | Land registry standard |
| Iraq | ~2,500 | Distinct regional unit |
Practical Advice for Cross-Border Land Dealings
- Always confirm which dunam definition applies when reviewing documents from multiple countries
- Request area measurements in square meters as a universal fallback
- For historical deeds, consult a local lawyer familiar with the jurisdiction's land law history
- Iraq is the major outlier — double-check dunam sizes if dealing with Iraqi property
