Why the Size of a Katha Keeps Changing

At JameenCalculator.in, we know that if you are dealing with real estate in Eastern India, you will quickly realize that nobody talks in Acres or Hectares for smaller residential plots. The standard language is always Katha. However, the biggest headache for buyers is finding out exactly how many square feet make up one Katha.

If you search online, some websites will tell you a Katha is 720 square feet, while others claim it is 1361 square feet. This creates massive confusion. The reality is that the size of a Katha depends entirely on which state you are living in. There is no single national standard for it.

The Three Main State Wise Rules

To make sure you do not get cheated during a property deal, just remember these three standard variations:

  • Bihar and Jharkhand: In these states, a standard Katha is traditionally equal to 1,361.25 square feet. This is the most common measurement used here.
  • West Bengal: If you cross the border into Bengal, the size of a Katha shrinks significantly. Here, the standard accepted value is just 720 square feet.
  • Assam: In Assam, the measurement is completely different and much larger. A single Katha here spans 2,880 square feet.

Why We Created This Specific Tool

We built this calculator because a one size fits all tool simply does not work for Eastern India. If a person from Bengal uses a Bihar based formula, they will end up paying for land that does not exist. With this state wise tool, you just need to select your region. The calculator automatically picks the right multiplier whether it is 1361.25 or 720 and gives you a mathematically perfect square feet area instantly.
