Use this workshop calculation to turn measured dimensions and the selected construction convention into a cut, spacing, fit, or material-planning value.

Inside Depth Millimeters (mm)

Required number input.

Rear Clearance Millimeters (mm)

Required number input.

Longest drawer-slide length that fits a measured cabinet interior depth after reserving a specified rear clearance; choose an available product size no longer than this result. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Maximum Slide Millimeters (mm)

The resulting maximum slide millimeters returned as a number.

• Nominal dimensions, kerf, moisture movement, hardware clearances, wall squareness, and manufacturer instructions can change the required shop dimension. Measure the actual assembly and test critical joints on scrap before cutting finished material.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculated dimension with a physical story stick, dry fit, or full-size layout. Follow the hardware, coating, adhesive, or machine manufacturer's limits where they differ from a rule of thumb.

• Drawer Slide Length

  Choose the longest supplied drawer-slide size that fits usable cabinet depth after rear clearance; no manufacturer sizes are assumed.

• Tenon Length

  Find maximum tenon insertion length from measured mortise depth after reserving a nonnegative end clearance.

• Dovetail Tail Count

  Count complete dovetail tails that fit an available joint width after reserving equal end pins and interior pin widths.
