Set edge clearances and choose your spacing method. Get totals for rows, lines, and patterns. Build straighter supports with fewer wasted skewers overall quickly.
| Scenario | Row length | Edge offset | Mode | Input | Lines | Typical outcome |
|---|---|---|---|---|---|---|
| Bed netting supports | 200 cm | 5 cm | Target spacing | 25 cm | 2 (staggered) | Even positions with stronger distributed support |
| Tomato guide skewers | 8 ft | 0.5 ft | Skewers per row | 7 skewers | 1 | Fixed count with equal edge gaps |
| Fabric pinning line | 3 m | 0.1 m | Target spacing | 0.3 m | 1 | Near-target spacing adjusted to fit the length |
First, compute the usable length: U = L − 2E, where L is row length and E is edge offset.
If end skewers are included, spacing is: S = U / (N − 1), where N is skewers in Line A.
If end skewers are not included, gaps are distributed evenly: G = U / (N + 1), and positions are E + kG for k = 1..N.
For two lines with staggering, Line B shifts by: S/2. Positions exceeding the usable boundary are omitted.
Start every row by defining a clear zero point at the same bed edge. Measure along the intended support line, not the plant canopy. Mark the usable length after subtracting end clearances, then snap a chalk line or string to keep placements straight under tension.
Smaller plants and lightweight netting can use wider intervals, while heavy fruiting vines often need tighter spacing to reduce sag. When you enter a target spacing, the calculator fits an integer number of gaps to the usable length, producing a practical “actual spacing” that repeats cleanly across rows.
Including end skewers places supports at both offsets, which anchors netting edges and limits lateral drift. Floating placements omit endpoints and create equal edge gaps, improving symmetry when bed ends are obstructed. Use edge offset to avoid splitting soil near boards or disturbing irrigation headers.
Dual lines are common for insect mesh, frost cloth, and trellis panels. Staggering Line B by half a step avoids stacking weak points, spreads bending loads, and reduces tear initiation around repeated contact zones. If the shifted position exceeds the boundary, it is omitted for a clean end.
Use CSV when you want a simple checklist of positions for multiple rows. Use the PDF to carry a compact summary to the garden. Standardizing spacing improves re-tensioning, quick replacement of broken skewers, and consistent plant training across a season. For crews, print one row template, then replicate marks using a measuring tape and marker. Record any deviations, such as shortened rows around paths, and rerun the calculator with updated length. When installing, push skewers vertically to a consistent depth so the top line remains level. If wind is expected, reduce spacing modestly and increase end offset stability with firmer soil packing. This practice speeds maintenance and keeps lines visually aligned.
Edge offset is the clearance from each end of the row before placing the first and last skewer. It protects bed edges, avoids irrigation fittings, and creates cleaner tension on netting.
Use target spacing when you want an approximate interval and flexible counts. The calculator selects an integer number of gaps that fits the usable length, then reports the resulting actual spacing.
Choose a fixed count when you must match existing holes, clips, or pre-cut netting. The calculator then distributes spacing evenly so each interval stays consistent along the row.
End skewers anchor fabric edges, reduce sideways drift, and improve tensioning. They also make the first and last positions predictable for repeated setups across many beds.
Staggering shifts the second line by half the spacing step. It prevents supports from aligning directly across lines, spreads loads more evenly, and can reduce tearing where mesh rubs repeatedly.
If the staggered shift pushes the final position beyond the usable boundary, the calculator omits that skewer. This keeps all placements inside the defined offsets and preserves consistent spacing.
