The size of a hammer is typically determined by its weight. This is because the weight directly influences the hammer's striking power and the type of work it is suited for. Heavier hammers deliver more force with each swing, making them ideal for driving nails into tougher materials or for heavy demolition work. Lighter hammers, on the other hand, are better suited for delicate tasks, such as finishing work or driving smaller nails.

While the length of the hammer or attributes like the height of the handle and the width of the head can play a role in comfort and control, it is primarily the weight that categorizes hammers for specific uses within carpentry and construction. Therefore, understanding the weight of the hammer is essential for selecting the right tool for the job, enhancing both efficiency and effectiveness in carpentry tasks.
