Trellis Netting Length
Calculator

It multiplies the length of your row or trellis structure by the number of vertical runs needed (often two, one on each side of the plants) to give total linear footage, since climbing plants are usually supported by netting on both faces of a trellis frame.

Vining plants like cucumbers or peas send tendrils out in multiple directions as they climb, so netting on both sides gives them something to grab regardless of which way they're growing, while a single-sided net can leave many shoots without support.

Yes, taller trellises need more netting height per linear foot of row, so a 6-foot-tall trellis needs proportionally more total netting area than a 4-foot trellis of the same row length, even though the horizontal length calculation stays the same.

Yes, add 10-15% extra to allow for securing the netting at both ends with enough overlap to tie off properly, and to have a small buffer for repairs if the netting tears during the growing season from wind or the weight of a heavy harvest.

Yes, smaller mesh (around 3.5-4 inches) suits plants with thin tendrils like peas, while larger mesh (6-7 inches) gives easier access for harvesting bigger fruit like cucumbers or squash without needing to reach through a tight grid.
