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

Stain parts

Required number input.

Thinner parts

Required number input.

Stain volume (l)

Required number input.

Calculate the thinner-to-stain dilution ratio and the resulting diluted volume. 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]

Dilution ratio

The resulting dilution ratio returned as a number.

Diluted volume (l)

The resulting diluted volume 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.

• Stain Mixing Ratio

  Volumes of stain concentrate and thinner needed for a target mixed volume at a supplied concentrate-to-thinner parts ratio.

• Chamfer Width Calculator

  Calculate the resulting chamfer width from chamfer depth and angle in degrees.

• 4-Inch Baluster Spacing

  Count equal-width balusters and calculate equal clear gaps, including both end gaps, so none exceeds a four-inch maximum.
