Tree tags can be customized in different lengths based on the diameter of the trees.

The formula for calculating the circumference of a tree is: Tree diameter * 3.14 equals tree circumference + 10 cm for the lock equals the total length of the tree lock required.

For trees with a diameter of 10 cm, a 40 cm long plastic tree tag can be used.

For trees with a diameter of 12 cm, a 50 cm long plastic tree tag can be used.

For trees with a diameter of 15 cm, a 60 cm long plastic tree tag can be used.

For trees with a diameter of 19 cm, a 70 cm long plastic tree tag can be used.

The plastic lengths are fixed in these four sizes: 40 cm long plastic, 50 cm long plastic, 60 cm long plastic, and 70 cm long plastic. For thicker trees, only steel wire tag locks can be used. The length of the steel wire can be custom-made and extended to different lengths.

Common features of plastic and steel wire:
