Most of the bricks are constructed in such a way that they can fit into a 4-inch grid with the other construction materials such as doors, windows and wood components.

Standard Brick Size and Weight:

The ratios of length x breadth x thickness are so chosen that the bricks, when laid in masonry, make a pattern (or Bond) so that vertical joints do not come one above the other in alternate courses.

Larger sizes that require a mason to use both hands to lift and place in masonry should be about 17-18 Kg and are termed as Blocks.
