Baseboard planning calculator

How the calculation works

• Perimeter = 2 × (room length + room width).
• Net length = perimeter − excluded openings + additional returns.
• Planning order length = net length × (1 + waste allowance ÷ 100).

What the result assumes

• This models a rectangular room with a uniform profile. Deduct openings only where baseboard actually stops.
• The waste allowance is an editable planning assumption, not a recommendation for every layout.
• This is not a final cut list. Stock lengths, nesting cuts, corner long points, grain selection and defects require review before ordering.

Check before using the result

• Excluded openings cannot exceed the included room perimeter. Confirm the actual runs and final cut list before ordering.

Attach inputs, net length and allowance to an editable trimwork request. Final field measurement and cut list remain required.
