If you've ever tried to buy or sell a piece of land in Bangladesh, you probably know how confusing land measurement can get. The different units, the regional variations, and the old habits of using traditional terms can leave even the smartest buyers scratching their heads. Whether you're a first-time land buyer, a property investor, or just someone curious about how land sizes are calculated—this guide is for you.
We’re about to break down every commonly used land measurement unit in Bangladesh in a super easy and engaging way. No technical jargon, no confusion—just straight-up clarity.
Why Land Measurement Knowledge Matters
Before diving into the units, let’s understand why this topic deserves your attention. Land is one of the biggest investments most people make. Whether it’s a plot for your dream home or farmland in your ancestral village, knowing the correct land size is vital.
Misinformation or misinterpretation of units can lead to serious financial loss. Real estate frauds are common when buyers don’t understand how land is measured. That’s why this knowledge isn't just helpful—it’s necessary.
The Two Dominant Systems: Traditional vs. Metric
Bangladesh mainly uses two systems of land measurement: the traditional Bengali system and the modern metric system.
In urban areas like Dhaka or Chittagong, people often use metric units such as square feet or square meters. However, in rural areas and official documents, traditional units like Decimal, Katha, Bigha, and Acre still rule the game.
To avoid getting caught in this mix, it's essential to understand both systems and how they relate to one another.
What is a Decimal? The Most Widely Used Unit
Decimal is perhaps the most commonly used land unit across Bangladesh. One Decimal is equal to 435.6 square feet. That’s roughly the size of a small one-bedroom apartment.
It’s a very popular unit because it’s easy to convert and use in various regions. Whether you’re in Rajshahi or Khulna, most people understand the concept of Decimal.
Understanding Katha: Region-Based Complexity
Now here’s where things get tricky. The size of a Katha isn’t fixed all over Bangladesh. In Dhaka and nearby areas, 1 Katha equals 720 square feet. But in Rajshahi and Khulna, 1 Katha can be as large as 1,620 square feet.
This variation can cause major confusion if you don’t double-check the local standard. Always ask what measurement system is being followed before finalizing any deal.
The Bigger Picture with Bigha
A Bigha is a larger unit and again, its size varies by region. In general, 1 Bigha equals 20 Kathas. That means in Dhaka, 1 Bigha equals 14,400 square feet (20 x 720).
But in Northern Bangladesh, that same 1 Bigha might go up to 32,400 square feet (20 x 1,620). So, it’s not just a measurement—it’s a regional language you have to learn.
The Global Unit: Acre in Bangladesh
Acre is part of the imperial system and is mostly used in larger land transactions. One Acre is equal to 100 Decimals, or 43,560 square feet.
Real estate developers and government records often use Acres to denote bigger land parcels. It’s useful when you’re dealing with agricultural lands or large-scale development projects.
Square Feet and Square Meters: The Urban Standard
In cities, land is usually measured in square feet or square meters. One square meter equals 10.76 square feet.
Apartment buildings, shopping complexes, and commercial land parcels generally follow this format because it aligns with construction and legal standards.
Hectare: The Lesser-Known Metric Unit
While not commonly used by everyday people, the term Hectare appears in government records and agricultural surveys. One Hectare equals 2.471 Acres or 10,000 square meters.
You’re more likely to see this unit in official documents, not in casual conversations.
Translating Between Systems: Handy Conversions
Let’s keep it simple. Here are some quick conversions to help you make sense of the mix:
Whenever you're unsure, pull up a conversion calculator or ask a local real estate agent to clarify.
Land Measurement in Land Deeds (Dalil)
Your land deed or "Dalil" in Bangladesh will always specify the land size in the traditional units. You’ll often see Kathas and Bighas mentioned, especially in older documents.
When you register land, make sure to cross-verify the mentioned size in both traditional and metric units to avoid any future legal headaches.
Modern Tech to the Rescue: Digital Land Records
Thanks to the digitalization of land records, you can now verify land size and ownership online through the government’s Land Information System (LIS).
This reduces the risk of fraud and helps people understand exact land measurements without having to rely solely on verbal communication or old paperwork.
Common Mistakes to Avoid
One of the biggest mistakes is assuming all Kathas or Bighas are the same size. As we’ve already mentioned, regional variations make a big difference.
Another common issue is not converting correctly between metric and traditional units. Always double-check using reliable tools or expert advice.
Why Buyers and Sellers Must Be on the Same Page
During a property deal, both parties must understand and agree on the land size using the same unit. Miscommunication can lead to disputes, especially when pricing is involved.
Being clear from the beginning ensures a smooth transaction and builds trust on both sides.
Real Estate Agents and Their Role in Clarity
A knowledgeable agent will help you understand the land measurements in your specific region. They act as a bridge between traditional and modern systems.
Always ask your agent to provide both traditional and metric measurements so you can cross-check and feel confident.
The Role of Surveyors in Accurate Land Measurement
Licensed surveyors use professional tools to measure land. Their reports are usually the most accurate and legally binding.
If you’re buying a large piece of land or have doubts about the actual size, investing in a professional survey can save you from future problems.
Using Land Measurement Apps in Bangladesh
There are now mobile apps that help you measure land on-site. They use GPS and satellite data to provide a fairly accurate picture.
While not as accurate as a professional survey, these tools are helpful for getting a quick idea.
Final Thoughts: Mastering Land Measurement in Bangladesh
Understanding land measurement in Bangladesh isn’t just about numbers—it’s about protecting your investment, making smart choices, and avoiding costly mistakes.
Once you grasp how traditional and modern units compare, you’ll feel much more confident in any property-related decision. And remember, it’s always okay to ask questions, consult professionals, and double-check details.
