West Bengal Bigha Katha Land Measurement Standard Guide
Complete guide to West Bengal land measurement units — Bigha (14,400 sq ft), Katha (720 sq ft), Chatak (45 sq ft) — used in Kolkata and Bengal property transactions.
West Bengal uses a distinct land measurement hierarchy: Bigha (14,400 sq ft), Katha (720 sq ft), Chatak (45 sq ft), with 20 Katha to a Bigha and 16 Chatak to a Katha. These figures are significantly different from UP and Bihar standards — the Bengal Bigha is almost exactly half the UP Bigha.
This causes confusion when land is sold across state borders or when buyers from other states purchase property in West Bengal. A Kolkata plot listed as “3 Bigha” contains 43,200 sq ft — not the 81,675 sq ft that a UP buyer might expect.
Use our state-specific calculators: bigha to square feet in west bengal, katha to square feet in bihar (Bihar uses the same Katha size), and chatak to square feet in west bengal for complete Bengal land measurement coverage.
