When referring to a hole in wood, what is the typical size indicated?

In woodworking and carpentry, a hole is often measured based on the size of the drill bit or the intended application. A hole of 1 and a quarter inches is a common size used for various fittings, such as those involving pipes, brackets, or other hardware that require a more significant opening. This dimension strikes a balance between being large enough for many common tasks while still being manageable in terms of structural integrity of the wood.

Other sizes listed may not provide the same versatility or relevance in typical woodworking projects. For example, a 1 inch hole may be too small for many applications where larger fixtures are involved, while a 2 inch hole might be excessive unless specifically required for larger components. A 1/2 inch hole, while useful for smaller screws or dowels, often does not meet the needs of the more substantial hardware that is commonly used in practical applications. Thus, 1 and a quarter inches serves as a standard size for various woodworking and construction tasks.
