The overall length of a Forstner bit affects both the depth of hole you can drill and the stability of the bit during use. Most Forstner bits, such as the 7/8" Forstner Bit 3/8" Shank Amana Tool 600-150 and 1-3/8" Forstner Bit 3/8" Shank Amana Tool 600-190, have a standard length of around 3-1/2", which is optimal for most woodworking tasks. This length offers a good balance between reach and control, allowing you to drill deep enough for most joinery and hardware installations without excessive flex or wobble. Some specialty tasks may require shorter or longer bits, so the available range ensures you can choose a bit that suits your specific drilling depth requirements.
