Step 1. Location of Cabinet Hardware
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 your to make!
Step 2. Mounting Cabinet Hardware
When drilling for a knob or pull, a 3/16″ hole is recommended for most styles. The exception is pulls that have “studs”. A stud is simply an extension of the molded screw holes. If a pull has a stud, then a 1/4″ hole is required with studs sitting securely in the wood.
IMPORTANT Screw Information
Most brands include 8-32 x 1″ long machine screws with most 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) used 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 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 doorcorner.com and other online retailers.
A. Mounting Pulls
Sizes Available
Pulls can be obtained in U.S. measurements as well as metric.
Most brands offer a broad range of sizes to choose from. 
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
Installation Tips: If you are using a pull, you will want to determine the hole center spacing of the pull. 3″ hole centers are the most common. However, most brands offer a wide variety of sizes. You may want to create or purchase a durable template prior to drilling to mark the mounting holes. This will help to ensure that they are parallel with the door or drawer edge and that they are the same placement height on every cabinet.
B. Mounting Knobs
Sizes Available
Knobs can be obtained in a variety of sizes, shapes, and diameters. Most brands 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 doors and drawers. A 1-1/4″ or 1-3/8″ diameter knob is the most popular. 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, pullout cutting boards, etc.
Installation Tips: If you are installing a knob, it is suggested that you create or buy 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 there is the same
placement height on every cabinet.
