Cabinet Drawer Pull Placement Calculator for Dead-Center Spacing

How to Use the Calculator

This tool calculates the exact dead-center drill hole coordinates for cabinet drawer knobs and handles, ensuring perfectly aligned hardware installation using standard tape measure fractions.

1. Select your Hardware Type from the dropdown menu to trigger the correct math for a 1-Hole Knob or a 2-Hole Pull / Handle.
2. Enter your Drawer Front Width using the whole inches and exact 1/16th fraction dropdowns.
3. Enter your Drawer Front Height using the whole inches and exact 1/16th fraction dropdowns.
4. Enter the Hardware Hole Spacing (Center-to-Center) using the whole inches and exact 1/16th fraction dropdowns (required only for 2-Hole Pulls).

Understanding Your Results

• Vertical Center Line (Y-Axis): The system divides the drawer front height in half to establish the exact level line from the top or bottom edge.
• Knob Drill Hole (X-Axis): For single-hole hardware, the calculator divides the drawer front width by two to pinpoint the dead-center point.
• Left Pull Drill Hole (X-Axis): For handles, the math finds the exact horizontal center and subtracts half the hardware hole spacing. Hook your tape on the left edge to mark this first hole.
• Right Pull Drill Hole (X-Axis): The tool adds half the hardware hole spacing to the horizontal center. Keep your tape hooked on the left edge to mark this second hole without moving the tape, preventing compound measuring errors.

All decimal coordinates are automatically converted into exact 1/16th tape measure fractions so you never have to translate math on the fly.

Tools Needed

• Tape measure (with exact 1/16″ markings)
• Combination square or speed square
• Power drill with a brad point bit
• Awl or center punch
• Painter’s tape

Always check local building codes and HOA guidelines before starting.

Project Overview

Using a cabinet drawer pull placement calculator eliminates the guesswork of finding the exact dead-center drill hole locations for your hardware. Miscalculating your cabinet drawer pulls placement ruins expensive drawer fronts and forces costly replacements. Accurate math dictates the final look of the cabinetry, whether you are centering a single knob on a narrow vanity or splitting the difference for a wide handle.

This hole spacing calculator automatically adjusts between 1-hole and 2-hole hardware types, taking your standard measurements and outputting specific coordinates for a flawless layout. By pulling both left and right drill hole locations from a single left-edge reference point, you lock in perfect drawer handle placement and prevent compound layout errors before you pick up a drill.

Where to place drawer pulls?

Drawer pulls should sit perfectly dead-center on the drawer front. Measure the exact middle of the vertical height and the exact middle of the horizontal width. For 2-hole handles, center the hardware’s center-to-center hole spacing evenly across that vertical center line.

Plug your drawer dimensions into the calculator above to get the exact left-to-right drill marks for your specific hardware.
