Measure your frame or area
- Top only: length and width plus 0.5 m on every side, so it hangs over and can be tied down.
- Top and sides: the net goes over the top and down the outside to the ground: width + 2 × height, by length + 2 × height. The posts do not need to be wrapped.
- Sides only: a strip as high as the frame and as long as all four sides together.
- Grapes on top of a pergola: one net over the vine and down the sides as deep as the grape layer (width + 2 × depth, by length + 2 × depth), and a second net underneath the bunches (width × length). Tie the two together all round; the posts stay free.
Fruit tree? Measure the tree as if it were a frame: the height, and the branch width both ways. Wider than 3 m? Run a wire across the middle so the net does not sag.
