While there are no hard, fast rules for placement of a knob or pull on a cabinet door, most cabinet makers will locate them approximately 3" - 4" above the upper non-hinged corner on base cabinets, or the lower non-hinged corner on wall cabinets. However, the decision is yours to make!
When drilling for knob or a pull, a 3/16" hole is recommended for most styles. The exception is for pulls that have "studs". A stud is simply an extension of the molded screw holes. If a pull has a stud, a 1/4" hole is required with studs sitting securely in the wood.
Most manufacturers include 8-32 x 1" long machine screws with their knobs and pulls because the typical cabinet door or drawer front is 3/4" thick. This screw length should work in most applications. However, if your cabinet doors or drawer fronts are thicker than 3/4" you will need to use longer screws for mounting. Check the thickness of both a cabinet door and a drawer front in your kitchen, as the thickness dimensions may not be the same. In general, the screw length(s) you use should be 1/4" longer than the thickness of your cabinet door or drawer front material. It is not uncommon for some drawers to be constructed with a 3/4" thick drawer front attached to a 3/4" thick drawer box. In this situation, the total drawer thickness is 1-1/2", making a 1-3/4" long screw necessary for mounting. These screws may be purchased from any hardware store.
Sizes Available

How to Choose the Right Size
Take note of all sizes available
3" is the most common size pull
Size is determined by measuring from hole to hole, not by the length of the pull itself
If you are using a pull, you will want to determine the hole center spacing of the pull. The most common are 3" hole centers, however, we offer a wide variety of sizes. You may want to create a durable template prior to drilling
to mark the mounting holes and ensure that they are parallel with the door
or drawer edge and they are the same placement height on every cabinet. Below is an example of various hole center measurements. DO NOT USE THIS AS A TEMPLATE.
Sizes Available
Knobs can be obtained in a variety of sizes, shapes, and diameters. We offer a broad range of sizes to choose from.
How to Choose the Right Size
There are no right or wrong sizes when it comes to selecting the appropriate knob size. Choose the size that looks best in proportion to the size of your cabinet and drawers. The most popular size knobs are 1-1/4" or 1-3/8" diameter.
To create a dramatic effect, consider using a large (1-1/2" diameter or greater) or small (1" diameter or smaller) sized knob. Small sized knobs also work well on applications such as apothecary drawers, spice drawers, appliance garages, pullout cutting boards, etc.
If you are installing a knob, it is suggested that you create a durable template prior to drilling to mark the mounting hole. This will help to ensure that the knob is positioned properly on the cabinet door or drawer front and that all are the same placement height on every cabinet.
HARDWARE PLACEMENT IDEAS
When replacing pulls, the choices are numerous. You may choose to go with a pull with the same hole centers as your existing pull. Pull size is determined by measuring from hole to hole, not by the length of the pull itself. However, if you choose to use a pull which is longer or shorter, the following information will assist you.
On wall cabinets, reuse the bottom hole and drill a new top hole
On base cabinets, reuse the top hole and drill a new bottom hole
On drawers, drill two new holes and realign in the center
If the holes don't match, use backplates behind the new hardware to cover the old holes
When replacing knobs, simply unscrew your old knob. Leaving the old screw in place, screw on your new knob.
If you are switching sizes of pull, or from a knob to a pull or a pull to a knob, there may be one or more exposed holes in the cabinet surface. To remedy this situation, you may choose to use a backplate.
Backplates are used in conjunction with a knob or a pull. It is placed between the cabinet door or drawer surface and the knob or pull. Backplates will also help to protect the wood surface, and may visually enhance the existing decorative hardware.
