The most common size of a mortar joint is:

  1. 1/4"

  2. 1/2"

  3. 3/8"

  4. 5/8"

The correct answer is: 3/8"

A 1/4" is typically too thin for a mortar joint and may not provide enough support for the bricks or stones. B: 1/2" may be too thick for a mortar joint, resulting in excess mortar that may be unsightly. D: 5/8" is considered large and may not adhere well to the bricks or stones, leading to potential cracking and settling. Therefore, the most common and recommended size for a mortar joint is 3/8", providing a good balance of strength and aesthetics.
