What is the length of a standard concrete block including the mortar joint?

Explanation:
Standard concrete blocks are made so that when you include the space taken by the mortar between blocks, the length along a row comes out to a round measurement. A typical block is about 15 5/8 inches long, and the mortar joint between blocks is usually 3/8 inch thick. Adding those together gives 15 5/8 inches plus 3/8 inch, which equals 16 inches. So, the length of a standard block including the mortar joint is 16 inches.
