About This Cabinet Hardware Calculator

Our cabinet hardware calculator helps you determine the optimal placement for drawer pulls, knobs, and handles on cabinet doors and drawers. Whether you're updating existing cabinets with new hardware or installing hardware on new cabinets, this tool provides precise measurements for professional-looking results.

Consistent hardware placement is key to a polished kitchen or bathroom appearance. The calculator provides center positions for both horizontal and vertical alignment, edge offsets for handle placement, and screw hole spacing for bar pulls and handles.

This calculator is ideal for DIY homeowners upgrading cabinet hardware, kitchen renovators, and anyone asking "where should I place cabinet pulls?" or "what is the standard height for drawer handles?" Using a template or jig based on these measurements ensures consistent placement across all cabinets.

How to Use This Calculator

Follow these steps to calculate hardware placement:

  1. Measure the width and height of your drawer front or cabinet door in inches
  2. Enter the width of your pull or handle (center-to-center for screw holes)
  3. Review the calculated center positions for horizontal and vertical placement
  4. Note the edge offset for handles placed near door edges
  5. Use a template or jig to mark and drill consistent holes
Frequently Asked Questions

Where should I place knobs on cabinet doors?

For upper cabinets, place knobs 2.5-3 inches from the bottom corner on the door's opening side. For base cabinets, place knobs 2.5-3 inches from the top corner. This creates visual balance and makes the cabinets easy to open. Some prefer centering knobs vertically on upper cabinet doors for a more modern look.

What is the standard height for drawer pulls?

Drawer pulls are typically centered both horizontally and vertically on the drawer front. For tall drawers over 10 inches, place the pull in the upper third of the drawer for better leverage. Bar pulls are usually mounted horizontally on drawers and vertically on doors for comfortable grip.

What drill bit size do I need for cabinet hardware?

Most cabinet hardware uses 8-32 machine screws requiring a 5/32-inch drill bit. European-style hardware may use M4 screws requiring a 5mm bit. Always check your hardware specifications. Drill from the front of the cabinet door to prevent splintering on the visible surface.

Should I use knobs or pulls on cabinets?

Pulls are easier to grasp and better for heavy drawers or people with arthritis. Knobs have a traditional look and are less expensive. A popular approach is knobs on doors and pulls on drawers. Use pulls at least 3 inches wide for comfortable grip on frequently used cabinets.

How do I make a cabinet hardware template?

Cut a piece of cardboard or thin plywood to match your drawer front size. Mark and drill holes for the hardware position. Hook the template over the drawer edge and use it to mark all similar drawers. Commercial jigs with adjustable guides are available for around $20-40 and save significant time.

How do I fill old cabinet hardware holes?

Fill old holes with wood filler or auto body filler for a smooth finish. For large holes, use wooden toothpicks dipped in wood glue before filling. Sand smooth, prime, and paint. If the new hardware has a wider spread, you may be able to cover old holes. Some back plates are designed specifically to cover existing holes.
