Commonly-cited approximate figure — confirm the exact local value with your state or district land revenue department before any transaction.How big is one bigha in Bihar?
One bigha in Bihar measures 27,225 square feet. The same area is 3,025 square yards, 2,529.29 square metres, or about 0.625 acres — and because an acre is fixed worldwide at exactly 43,560 square feet, one acre holds roughly 1.6 bigha. The figure derives from 20 katha = 3,025 sq yd (Patna region). In local practice the bigha divides into 20 katha, and most transactions are actually quoted in that sub-unit rather than in bigha. For scale, the smallest bigha in the country is 6,806.25 square feet and the largest is 27,225 — a fourfold spread across one country. The bigha is not a national standard: each state fixed its own, and several fixed more than one. These are commonly-cited reference figures rather than legal standards — the area recorded by your district land revenue office is what governs any transaction. Last checked 2026-08-03.
