The term used to describe the measurement that combines button diameter and depth.

• A. Button gauge
• B. Hole spacing
• C. Buttonhole formula
• D. Button size index

Answer: (C)

The measurement that combines button diameter and depth is described by the buttonhole formula. This formula guides how long a buttonhole should be so a button fits through it, taking into account both the button’s diameter and its thickness (depth). A thicker or larger button needs a longer hole, while a thinner button needs less. This concept is different from a button gauge (a tool to measure button size), hole spacing (distance between holes on a button), or a button size index (a size-category system). The buttonhole formula is the method used to calculate the correct hole length based on the button’s overall size.
