Match or replace the hinges
If your cabinets have hinges that show from the outside, you will probably want to select knobs and pulls that match the color and style of the hinges. It’s also possible that your hinges have tarnished over time. Many of our knobs are available in finishes that may match these tarnished hinges. Or you can replace the hinges as well (hinges are usually available at hardware stores – take one of yours into the store to get an exact match on the size).
For pull handles, measure the center-to-center distance between the two screw holes
If you are replacing a pull handle with a 3 inch center-to-center measurement between the screw holes, you will probably want to select new handles that are also 3 inch center-to-center (not the overall length of the pull -measure from screw hole to screw hole).
Double-check the clearance
If you have cabinet doors that open from the center, with the knobs from each cabinet right next to the other, measure the distance between the knobs. If you choose too large a knob, they may either touch or be very close together, which may not be the look you want.
