Let’s explore the essentials of identifying your cabinet hardware size and what factors influence this important decision.

Measuring Your Cabinet Hardware

Determining the correct size of your cabinet hardware primarily involves measuring the distance between the screw holes, commonly referred to as the “center-to-center” measurement. This is the standard way manufacturers and installers specify sizes for handles, pulls, and knobs.

To measure your cabinet hardware size accurately:

  • Use a ruler or tape measure with millimeter or inch markings.
  • Measure from the center of one screw hole to the center of the other screw hole.
  • For knobs, which typically have a single screw, measure the diameter of the base or the knob’s face.
  • If the hardware is already installed, remove one piece and measure it directly to avoid errors.
  • For handles or pulls without pre-drilled holes, measure the entire length and width to ensure proper fit.

Keep in mind that some hardware may come in non-standard sizes, so always verify if the measurement matches the replacement specifications.
