What are the minimum height and width specifications recommended for an effective perimeter wall for security purposes ?

For effective physical security, the recommended minimum specifications for a perimeter wall are a height of 08 feet and a width of 12 inches. These standards are widely cited in industrial security manuals and training modules for security personnel (such as those aligned with PSARA and SSSDC guidelines in India).

• Height (08 feet): A height of approximately 2.4 meters is considered the standard minimum to act as a deterrent against unauthorized climbing. It is typically high enough to require tools or significant effort to scale.
• Width (12 inches): A thickness of 12 inches (approx. 30 cm) provides the necessary structural stability and resistance against physical breaching or impact. While a standard brick wall is 9 inches, a 12-inch wall (often 1.5 bricks thick) is recommended for enhanced security.

High-security installations may increase the height to 10-12 feet and add top guards like concertina coils or barbed wire.
