Consider proportion, balance, aesthetics and function when deciding upon the size of a knob or pull for your kitchen cabinetry. A large cabinet door or drawer needs a larger piece of hardware, or maybe two, for proper functionality, but a smaller size knob or pull is appropriate for a smaller door or drawer. A good rule of thumb for traditional or transitional style pulls is that they should be about one-third of the length of the cabinet drawer. Drawers larger than eighteen inches wide may require more than one pull or knob. However, more contemporary designs call for longer pulls that are at least two-thirds of the length of the drawer or cabinet door. 


The cons are a few: 1. MDF is heavy in relation to wood or plywood. 2. MDF does not accept screws very well. You must use coarse thread screws and always pre-drill. Apply the hinge screws by using a hand-held screwdriver instead of a screw gun. If you don't, they can strip the hole quickly. 3. Over time the screws will come lose just from opening and closing the doors (just go around every so often and tighten the screws). 4. If water gets into the doors, they will swell and they will need to be replaced so seal them well.
Now comes the fun part, place the point of the forstner bit in the center hole you marked earlier and start drilling, drill the holes ½” deep, that’s the thickness of the bit. The instructions on the back of the kit say “do not drill completely through the door,” Ummm, OK… You’ll want to do this twice on every door, 36” or 42” doors may need 3 hinges each. Let’s backtrack a little here, when you remove the doors mark them and the cabinet box so you’ll know where they go back. Now, do that over and over and over again until all your doors are finished.
And then there’s appliance hardware. Appliance pulls are not just hardware pulls that have a higher price point. It is a more durable hardware that look identical in style to your standard pulls, but are designed for the larger items in your kitchen like refrigerators, dishwashers, pantries, and oversized drawers. They come in a range of sizes from 6” to 36” and are constructed to hold a heavier weight, typically necessitating longer screws and a backplate for installation. The screws can be shortened to the needed size, but its best to follow the instructions and have these pieces installed by a professional to avoid hiccups.
Generally speaking, I like to see a combination of knobs and handles/pulls. Knobs or handles for the doors and handles or pulls for the drawers. If you are painting your kitchen, the extra holes can be filled, sanded, and smoothed prior to painting so you can start with a clean slate and choose any hardware for your update. I say “generally speaking” because lately I’m drawn to kitchens that have all handles like this “before” photo of a kitchen we recently updated.
