Tile size follows selected units.
Pattern presets auto-suggest typical waste ranges.
In selected units
Doorway sides suppress edge-cut counts on the chosen walls.
Offset along tile length
Offset along tile width
Alcoves and columns increase cut complexity (counts), not area. Adjust area via exclusions if needed.
| # | Name | Length | Width | Angle (°) | Alcoves | Columns | Exclusions | Unit | Area | |
|---|---|---|---|---|---|---|---|---|---|---|
| Gross area | 0.00 | |||||||||
| Net area (after exclusions) | 0.00 | |||||||||
Exclusions are sub-areas to subtract (e.g., built-ins). Use same units.

Formula Used
- Tile area = tile length × tile width.
- Gross area = Σ(length × width) across rooms.
- Net area = gross area − Σ(exclusions).
- Allowance factor = 1 + (base waste% + extra overage% + dye-lot%) ÷ 100.
- Effective area = net area × allowance factor.
- Tiles required = ceil(effective area ÷ tile area).
- Boxes required = ceil(tiles required ÷ tiles per box).
- Cut tiles (simple) ≈ ceil(tiles required × pattern cut%).
- Pattern-aware cuts: leftover strip logic with offsets, optional border tiers, door “no-cuts” suppression, and extra complexity from alcoves/columns.
How to Use
- Select units and tile size (or a preset).
- Choose pattern and confirm base waste percentage.
- Select cut model: Simple or Pattern-aware.
- Choose a border style; set band width if used.
- Optionally mark doorway walls as “no cuts”.
- Enter per-room counts for alcoves/columns and angles.
- Set starting line offsets or click Optimize.
- Enter pack sizes and optional pricing; Calculate and export.
FAQs
It counts border tiles separately from the field for ordering a different color or SKU. The total tiles remain the same; the split is shown in results.
No. They only suppress edge-cut counts on selected sides. Adjust area via exclusions if thresholds or recesses change coverage.
They increase cut complexity heuristically using average sizes. If an alcove reduces area, subtract it via the exclusions column to avoid over-ordering.
No. It only aims to reduce estimated cut tiles by choosing starting offsets that align the grid more favorably with room edges.
This version uses a global band width. If you need per-room borders, I can add a per-row override column.
