Why Thai Land Measurements Matter in Pattaya Real Estate

When exploring property options with Lakeside Property Pattaya, you'll notice land sizes listed in traditional Thai units: Rai, Ngan, and  Wah. Understanding these measurements is crucial for:

• Accurate Property Evaluation: Know precisely how much land you're considering.
• Investment Decisions: Calculate potential returns based on land size.
• Building and Development: Plan construction projects with exact land dimensions.

Breaking Down the Units

1. Tarang Wah (ตารางวา)

• Definition: The smallest unit of land measurement in Thailand and the most common for residential real estate.
• Conversion:
  • 1 Tarang Wah = 4 Square Meters
• Usage: Ideal for measuring small plots, residential lots, or individual house spaces.

What is a Tarang Wah? 1 Wah is 2 meters, a Tarang Wah or Square Wah Is therefore equivalent to 4 square meters, commonly used in property listings throughout Thailand.

2. Ngan (งาน)

• Definition: A mid-sized land measurement unit.
• Conversion:
  • 1 Ngan = 100 Square Wah
  • 1 Ngan = 400 Square Meters
• Usage: Commonly used for medium-sized properties, such as larger homes or small commercial spaces.

3. Rai (ไร่)

• Definition: The primary unit for larger land areas.
• Conversion:
  • 1 Rai = 4 Ngan
  • 1 Rai = 400 Square Wah
  • 1 Rai = 1,600 Square Meters
• Usage: Typically used for substantial plots like farms, resorts, or large development projects.

Converting Thai Units to Square Meters

Quick Reference Table

Since living areas are listed in square meters, converting land measurements helps in comparing and planning:

• Square Wah to Square Meters: Multiply by 4.
  • Example: 50 Square Wah × 4 = 200 Sq.m
• Ngan to Square Meters: Multiply by 400.
  • Example: 2 Ngan × 400 = 800 Sq.m
• Rai to Square Meters: Multiply by 1,600.
  • Example: 3 Rai × 1,600 = 4,800 Sq.m

Practical Examples for Pattaya Properties

• Residential Plot: A land listing of 80 Square Wah equates to 320 Sq.m (80 × 4).
• Large Land Plot: A property listed as 1-2-27 or 1 Rai 2 Ngan 27 Wah is:
  • 1 Rai = 1,600 Sq.m
  • 2 Ngan = 800 Sq.m (2 × 400)
  • 27 Wah = 108 Sq.m (27 x 4)
  • Total: 1,600 + 800 + 108= 2,508 Sq.m

The Origins of Thai Land Measurements

The Rai has its roots in Thailand's agricultural past, traditionally representing the size of land needed for farming. Over time, these measurements became standardized, with 1 rai being officially defined as 1,600 square meters.

The Ngan, equivalent to a quarter of a rai (400 square meters), was used for measuring medium-sized plots, often for family-owned fields or smaller agricultural purposes. It serves as an intermediate unit between the rai and smaller measurements, making it a practical unit for subdividing land.

The Wah (or square wah in its area form) was originally based on human proportions, with 1 wah representing the distance between the outstretched arms of a person, roughly 2 meters. 1 square wah (or talang wah) equals 4 square meters and is commonly used for smaller land divisions, particularly in urban and residential contexts.

Tips for Property Buyers in Pattaya

• Verify Land Titles: Always check the official land title for accurate measurements.
• Consult Experts: Engage with agents familiar with Thai measurements.
• Future Development Potential: Consider future infrastructure or development plans in the area, such as new highways, commercial centers, or residential developments, which could increase the land's value.
