Calculator inputs
The grid adapts: three columns on large screens, two on smaller, and one on mobile.
Example data table
| Use case | Surface (W×H) | Panel width | Repeat (X×Y) | Match | Expected panels |
|---|---|---|---|---|---|
| Trellis privacy screen | 240×120 cm | 60 cm | 20×25 cm | Straight | 4 |
| Raised-bed liner décor strip | 180×45 cm | 50 cm | 15×15 cm | Centered | 4 |
| Garden shed accent wall | 300×240 cm | 53 cm | 26.5×64 cm | Half-drop | 6 |
Numbers are illustrative; use your own measurements.
Formula used
- EffectiveWidth = (SurfaceWidth − 2×Margin) ÷ Scale
- PanelStep = PanelWidth − Overlap
- Panels = ceil(EffectiveWidth ÷ PanelStep)
- RepeatsAcross = ceil((EffectiveWidth + OffsetX) ÷ RepeatX)
- RepeatsDown = ceil((EffectiveHeight + OffsetY) ÷ RepeatY)
- SuggestedOffsetX = (Goal − (PanelStep mod RepeatX)) mod RepeatX
Goal is 0 for boundary, or RepeatX/2 for centered seams.
How to use this calculator
- Measure the surface area you want to cover.
- Enter the pattern repeat dimensions from your material.
- Enter panel width and any overlap at seams.
- Pick a match type that fits your visual goal.
- Press calculate to see offsets and repeat counts.
For outdoor use, test a dry fit before fixing panels.
