Standard plywood sizes and thickness in India

The plywood manufactured in India is of standard sizes and thickness. Though the metric system has largely been adopted in India, the prevalent practice in the plywood market is still to manufacture and sell the boards based on cost per sq.foot.

The top selling and most commonly manufactured plywood size in India is 8 feet by 4 feet. Other sizes such as 8x3, 7x4, 7x3, 6x4 and 6x3 sq.feet are also manufactured.
