Nepal Land Area Explained: Ropani, Aana, Paisa, Bigha & Kattha

In Nepal, land is still bought, sold and discussed in traditional units: ropani, aana, paisa and daam in the hills, and bigha, kattha and dhur in much of the Terai. Architects and municipal forms often want square feet or square metres. Mixing systems without converting carefully is how buyers misread a plot and how designs do not fit the land.

Use this guide to understand the units, then convert instantly with the free Nepal land area converter. If you have a Mero Kitta naksha rather than a deed figure, trace the map into an area with the free Area Plotter. If you are purchasing from abroad, pair this with the NRN land buying and verification guide.

Hill system: ropani, aana, paisa, daam

• 1 ropani = 16 aana
• 1 aana = 4 paisa
• 1 paisa = 4 daam
• In square feet, 1 ropani is commonly taken as 5,476 sq. ft. (so 1 aana ≈ 342.25 sq. ft.). Always confirm the convention used on the specific deed and survey.

Terai system: bigha, kattha, dhur

• 1 bigha = 20 kattha
• 1 kattha = 20 dhur
• Conversions to square feet/metres follow the regional standard used in the document. Do not mix hill and Terai units in one mental model without converting both to sq. ft. or m² first.

Why conversion matters before design

Built-up area, setbacks, parking and garden leftovers are calculated in modern units. A house planned for “plenty of space on 8 aana” can fail setbacks once the true square footage, road width and municipal rules are applied. Convert early, then work through the house construction planning checklist.

1. 1Convert the deed area to sq. ft. and m² with the land area converter.
2. 2Confirm usable area after setbacks, slope and access — not only title area.
3. 3Match proposed built-up area to a realistic coverage for the plot.
4. 4Budget the build with a construction cost estimate only after massing fits the land.

Common mistakes

• Confusing aana with kattha when family members live in different regions.
• Assuming price “per aana” is comparable across districts without checking location and road access.
• Designing to full title area while ignoring setbacks and right-of-way.
• Skipping independent measurement when buying from abroad through a representative.

After the land is clear

Once area and title are understood, move into stages: approvals, structure and finishing — see stages of building a house in Nepal. Track every land-related fee and later construction payment in one place so the project story stays complete from plot to handover.
