Brick Work Quantity Calculator (Girth Method)

Developed By: Mohan Dangi (Gold Medalist)

This calculator helps civil engineers, quantity surveyors, site engineers, contractors, and students calculate the quantity of brickwork using the girth method.

Formula Used

Brick Work Volume:

Volume = Total Girth × Wall Height × Wall Thickness

Brick Quantity:

Number of Bricks = Brick Work Volume × 500

(Approximate value of 500 bricks per m³ masonry)
