2,640 km of mountains, history and dispute — the Durand Line explained: how long it is, where it runs, and why it still matters.

The Essentials
The Border at a Glance
One of the world’s most consequential — and contested — frontiers.
Definition
What Is the Durand Line?
The name Pakistanis and Afghans use for the world’s most dangerous border.
The Durand Line — also called the Afghanistan–Pakistan international border — is the 2,640-kilometre frontier between the two countries. Its western end meets the Iranian border; its eastern end reaches China, near the Wakhan Corridor. Strategists have long called it one of the most dangerous borders in the world: it cuts through the Pashtun heartland, dividing tribes and families between two states.
Note the measurement: the full length is 2,640 km, though Pakistani military briefings on the fencing project sometimes cite 2,611 km — the difference is the stretch of impassable high-altitude terrain excluded from fencing plans. How the 2,640 km is measured →
History
How the Border Was Drawn: 1893–1947
A single-page agreement from the Great Game still shapes South Asia.
The Agreement
On 12 November 1893, Mortimer Durand of the British Indian Civil Service and Amir Abdur Rahman Khan of Afghanistan signed a seven-article agreement fixing their spheres of influence. A joint demarcation survey from 1894 mapped about 1,300 km of it.
The Treaty
The Anglo-Afghan Treaty of 1919 (Treaty of Rawalpindi, 8 August 1919), ending the Third Anglo-Afghan War, ratified the line in its current shape — and recognised Afghanistan’s full independence.
The Inheritance
Pakistan inherited the Durand Line on independence in 1947, as the successor state to British India. Every Afghan government since — monarchy, republic, communist, Taliban — has refused to formally recognise it.
Geography
The Route: Mountains, Deserts, Tribes
Lowlands, high peaks and glaciers — the hardest border terrain in South Asia.
On the Pakistani side the line runs through Khyber Pakhtunkhwa (including the former tribal districts — Khyber, Kurram, North and South Waziristan) and Balochistan (from Zhob down to Chagai, ending at the Iranian tripoint). The terrain the military describes for the fencing project says it all: lowlands, high peaks and glaciers.
What makes the Durand Line unique is human geography: it slices through Pashtun tribal territory, with the same tribes — Wazirs, Mehsuds, Afridis, Achakzais — living on both sides. For over a century, families, trade and seasonal migration have crossed it as if it were not there. That is precisely why fencing it has been so politically charged.
Security
The Fencing Project
One of the largest border-fencing operations in the world.
| Fact | Detail |
|---|---|
| Started | 2017, after cross-border militant attacks on Pakistani posts |
| Design | Double chain-link fence ~4 metres high with concertina wire, surveillance cameras and forts |
| Progress | ~98% complete (ISPR, April 2023); ~92% of border forts complete |
| Effect claimed | Illegal cross-border movement down ~80%; 78 informal crossings reduced to 5 formal points |
| Cost | Hundreds of kilometres of fence, ~388 new forts, demining of 72%+ of tribal areas |
The fence remains controversial: Kabul views it as an illegal attempt to formalise a line it does not recognise, and there have been clashes where Afghan forces tried to stop or damage construction. Pakistan’s position is that a managed border — with a One Document Regime requiring valid travel documents — is a security necessity.
Gateways
Border Crossings
Five formal gates handle trade, transit and travellers.
| Crossing | Province | Notes |
|---|---|---|
| Torkham | Khyber Pakhtunkhwa | The busiest crossing; historic Khyber Pass route to Jalalabad and Kabul |
| Chaman | Balochistan | Main southern crossing to Kandahar; key trade artery |
| Ghulam Khan | Khyber Pakhtunkhwa | North Waziristan route, opened for trade |
| Kharlachi | Khyber Pakhtunkhwa | Kurram district crossing |
| Angoor Adda | Khyber Pakhtunkhwa | South Waziristan crossing |
Before fencing there were 78 notified formal and informal crossings — effectively an open border. The One Document Regime now requires passports and visas, sharply cutting unauthorised movement while legal crossings have risen.
The Dispute
Why Afghanistan Disputes It
The objection is older than Pakistan itself.
Afghanistan’s case: the 1893 agreement was signed under British pressure, lapsed after 100 years (a claim historians dispute — the text contains no expiry), and was never validly inherited by Pakistan. Successive Afghan governments have raised the issue at the UN and in bilateral talks. Pakistan’s case: the line was confirmed by treaty in 1919, internationally recognised, and inherited under the standard rules of state succession in 1947 — the same basis as every other Pakistan border.
In practice, the dispute simmers rather than boils: trade, transit and security cooperation continue through the very crossings whose legal basis Kabul questions.
Context
Pakistan’s Other Borders
The Afghan frontier is Pakistan’s longest — but not its only one.
| Neighbour | Border length | Notes |
|---|---|---|
| Afghanistan | 2,640 km | Durand Line; disputed by Kabul |
| India | ~3,323 km | Including the Line of Control; the international border proper is shorter |
| Iran | ~909 km | 91% fenced under the same border-management programme |
| China | ~596 km | Khunjerab Pass; settled and peaceful — see the guide → |
Answers
Frequently Asked Questions
Everything people ask about the Pakistan-Afghanistan border length.
What is the border length of Pakistan with Afghanistan?
2,640 kilometres (1,640 miles) — the Durand Line, running from the Iranian border in the west to China in the east.
What is the Pak Afghan border length in km?
The Pak-Afghan border length is 2,640 km. Pakistani military briefings sometimes cite 2,611 km — the fenceable length excluding impassable high-altitude stretches.
Who drew the Durand Line?
Mortimer Durand, a British diplomat, and Amir Abdur Rahman Khan of Afghanistan signed the agreement on 12 November 1893; a joint survey demarcated it from 1894, and the 1919 Treaty of Rawalpindi confirmed it.
Is the Pakistan-Afghanistan border fenced?
About 98% is fenced — a double 4-metre fence with concertina wire, cameras and forts, built since 2017. The remaining stretch is mostly impassable mountain terrain.
Which are the main crossings between Pakistan and Afghanistan?
Torkham (Khyber Pass, busiest) and Chaman (to Kandahar) are the main gates, plus Ghulam Khan, Kharlachi and Angoor Adda.
Why does Afghanistan not recognise the Durand Line?
Kabul argues the 1893 agreement was coerced and temporary; Pakistan holds it was confirmed by treaty in 1919 and validly inherited in 1947. Every Afghan government since 1947 has maintained the objection.
