The numbers on a modular brick ruler represent how many rows or coarses in 16 inches. There are 6 coarses of modular brick in 16 inches so the number 6 on the ruler would properly space the coarsing to hit at 16 inch inervals. Oversize brick would lay out on a 5. Utility brick lay out on 4. Some glazed tile on a 3. Glass block and concrete block on 2.
Modular bricks are simple bricks of dimensions 200mm x 100mm x 100mm. Whereas conventional bricks are hard moulded bricks of dimensions 230mm x 115mm x 75mm.
A ruler
The brick spacing ruler is used by the bricklayer to measure and mark course heights (the distance from the top of one brick to the top of the next). It has standard markings of feet and inches on one side, and a series of marks on the other side that indicate course heights (black numbers) and the number of courses (red numbers). The purpose of the brick spacing ruler is to attain proper heights with consistent spacing of courses. It is typically used on brick veneer construction, where the brick walls are built upon preexisting walls, roofs and openings (doors , windows, etc) The spacing ruler is similar to the modular ruler except that its marks are used to compensate for irregular, or non-modular(4inch) heights. Standard bricks are made so that six courses, with six 3/8 inch joints equal a height of 16 inches. But if the height that needs to be "hit" varies from a modular height, then the spacing ruler is used to attain that height with a proper number of courses, and with consistently sized joints. For instance, if you were building a wall with a window opening at 49 1/2 inches above the foundation, you would measure up with the back side of the spacing ruler. In this case, you would find a mark with the numbers 6, in black, and 18, in red. Every course of brick should hit the marks that have the black number 6. The red number 18 indicates the number of courses to lay to meet that height. Now, lets say that your window height is 57 3/4 inches. You would again measure the height with your spacing ruler, and see that there are two pairs of corresponding numbers on your mark; black 6 / red 21 and a black 4 / red 22. You must decide on which black number you will use for your course height. If, for example, you need to attain 40 courses in total to match the number of courses on the other end of the wall, you would need to use the number 4 to mark the course heights (18 courses + 22 courses). The brick spacing ruler is an indispensable measuring tool for bricklayers.
you read a ruler by conting the little lines first
There are exactly 6.75 bricks per square foot. Standard modular brick courses 3 bricks per 8" vertically, and 8" per brick horizontally. Therefore, 1 square foot is 1.5 bricks wide x 4.5 bricks high, or 6.75 bricks per square foot. Keep in mind, there are MANY different brick sizes, but this calculation holds true for standard 'modular' brick.
UssaModular bricks are bricks that are used around doors and windows. They make it easier to install modular doors and windows because they create a 4 inch by 4 inch grid. Modular bricks also are made to lay 3 runs or courses to a single cinder block.(8 inches) This helps in tying the two walls together with much less headache and better reinforcement. Modular brick are typically 6 inches long and are easy to spot because they lay on an half bond as to where queen ,king size and ect. lay on a 3/4 bond.you also tend to have less cuts therefore less waste of materials and labor costs can help when using modular brick.
Put a ruler next to it and read the little numbers on the ruler...
by the numbers that are marked there

Difference between modular and non-modular bricks
A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.
