How to Calculate Land Share in Bangladesh | Step-by-Step Guide

Calculating land share in Bangladesh can seem complicated due to traditional measurement units, family inheritance laws, and regional variations. Whether you’re dividing inherited property among heirs or planning a land purchase, understanding the process is crucial. In this guide, we’ll walk you through how to calculate land share in Bangladesh step by step.

Understanding Land Share in Bangladesh

Land in Bangladesh is often measured in traditional units like katha, bigha, decimal, and acre. Before diving into calculations, it’s essential to know:

1 Katha (Dhaka area) = 720 sq. ft

1 Bigha = 20 Katha (varies regionally)

1 Decimal = 435.6 sq. ft

1 Acre = 33.17 Katha ≈ 43,560 sq. ft

Tip: Always confirm the local land measurement standards, as these vary across districts.

Land share is often calculated based on inheritance rules, sale agreements, or partnership arrangements.

Step 1: Identify the Total Land Area

Before calculating shares, determine the total size of the land. If the land area is recorded in multiple units (e.g., katha and decimal), convert everything into a single unit for accuracy.

Example:

If a plot is 2 Katha 15 Decimal:

Convert 2 Katha into Decimal → 2 × 100 = 200 Decimal

Add remaining 15 Decimal → Total = 215 Decimal

Step 2: Determine the Number of Shares

If the land is being divided among multiple heirs or partners, identify how many people the land will be divided among.

Example:

If 4 siblings inherit a land plot, there are 4 shares.

If shares are unequal, you need the exact ratio (e.g., 2:1:1:1).

Step 3: Calculate Individual Shares

Use the formula:

Individual Share

=

Total Land Area

×

Share Ratio

Total Ratio Sum

Individual Share=

Total Ratio Sum

Total Land Area×Share Ratio

 ​

Example 1 (Equal Share):

Total land = 215 Decimal

4 siblings (equal share) → Share = 215 ÷ 4 = 53.75 Decimal per sibling

Example 2 (Unequal Share):

Ratios = 2:1:1:1 → Total Ratio = 2+1+1+1=5

Individual share =

First sibling: 215 × (2/5) = 86 Decimal

Other siblings: 215 × (1/5) = 43 Decimal each

Step 4: Convert Back to Local Units

Once calculated, convert the share back into katha, bigha, or other local units to make it easier for legal documentation or agreements.

Example:

53.75 Decimal → 0 Katha 53.75 Decimal (if 1 Katha = 100 Decimal)

Step 5: Check Legal Documentation

Land division in Bangladesh requires proper legal documentation. Ensure:

Registered deed of ownership

Updated mutation (Porcha) records

Agreement signed by all heirs or stakeholders

Important: For inherited land, it’s advisable to consult a lawyer or local land office (Taluk/Upazila office) for proper legal guidance.

Common Tips for Calculating Land Share

Always double-check regional land measurement standards.

Use a calculator or spreadsheet for accurate division.

Keep records of previous transactions or mutation papers.

For disputes, a surveyor can help verify exact measurements.

Round off carefully when converting units to avoid discrepancies.

Final Thoughts

Calculating land share in Bangladesh doesn’t have to be confusing. By understanding units, ratios, and legal procedures, you can divide land fairly and avoid future disputes. Whether it’s inheritance, sale, or partnership, following these steps ensures a smooth and accurate land share calculation.
