Measure walls precisely and account for corners effortlessly. Reduce waste, compare finishes, and price accurately. Build confident room-by-room skirting plans with cleaner purchasing decisions.
Rectangular mode: Gross Perimeter = 2 × (Room Length + Room Width) × Number of Rooms
Custom wall mode: Gross Perimeter = Sum of all entered wall segments
Total Deductions: Door Openings + Other Openings + Excluded Sections
Extra Allowances: Added Sections + (External Corners × Corner Allowance Each) + (End Returns × Return Allowance Each)
Net Required Length: Gross Perimeter − Total Deductions + Extra Allowances
Waste Length: Net Required Length × Waste Percentage
Purchase Required: Net Required Length + Waste Length
Pieces Required: Ceiling(Purchase Required ÷ Stock Piece Length)
Ordered Length: Pieces Required × Stock Piece Length
Total Cost: (Ordered Length × Unit Rate) + Tax
Use rectangular mode for standard rooms. Use custom wall mode for offsets, alcoves, irregular plans, or mixed wall lengths.
Subtract door widths, other openings, and any sections where skirting will not be installed.
Include extra fixed sections, exposed end returns, and corner allowances where cutting or detailing needs extra material.
Enter waste percentage, stock length, unit price, and tax rate to generate ordering quantities and project cost.
After calculation, check net required length, ordered length, joints, offcuts, and total cost. Then download CSV or PDF for procurement records.
| Scenario | Mode | Room / Segments | Deductions | Waste % | Stock Length | Estimated Order |
|---|---|---|---|---|---|---|
| Living Room | Rectangular | 5.0 m × 4.0 m × 1 room | 1.50 m | 10% | 2.40 m | 10 pieces / 24.00 m |
| Office | Rectangular | 6.2 m × 3.6 m × 2 rooms | 2.10 m | 8% | 2.90 m | 14 pieces / 40.60 m |
| Irregular Hall | Custom | 4.8, 3.2, 1.4, 2.1, 4.8, 3.2 | 1.80 m | 12% | 2.40 m | 9 pieces / 21.60 m |
Example values are illustrative. Final quantities depend on installation pattern, miters, return details, and stock availability.
It is the total trim length installed along the lower wall perimeter, usually after subtracting door gaps and other non-covered sections.
Usually yes, because skirting does not continue through most door openings. Measure each opening carefully and deduct only the uncovered width.
Waste covers cutting losses, breakage, damaged pieces, miscuts, grain matching, and on-site adjustments. Complex layouts often need a higher waste allowance.
Normally no. Internal corners affect cutting and fitting, but they do not usually add linear length. External corners and returns often need small extra allowances.
Use the supplier’s actual sellable length, such as 2.4 m, 2.7 m, or 3.0 m. Ordering calculations depend on full purchasable piece lengths.
Because suppliers sell full pieces, not exact fractional lengths. The calculator rounds up to whole pieces, which creates offcuts and spare material.
Yes. Enter each wall segment individually. This mode is better for stepped walls, niches, corridors, bay windows, and rooms with multiple offsets.
No. It is a planning tool. Always verify dimensions, installation details, profile compatibility, finish direction, and contractor cutting methods before ordering.
