This is important when using glide hardware because the drawer bottom determines how the hardware will fit and operate. It is important to purchase your hardware before starting to make your drawers. We need to get the specs of drawer size and bottom position before starting to make the drawers for the project.
If your not using hardware or making wooden glides the standard distance from the drawer side edge is 3/8”. For this example we are not using hardware so our offset will be 3/8” giving us maximum space in the drawer and good support for the groove joint.
