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

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

Trees with a diameter of 10 cm can use a 40 cm long plastic tree tag.

Trees with a diameter of 12 cm can use a 50 cm long plastic tree tag.

Trees with a diameter of 15 cm can use a 60 cm long plastic tree tag.

Trees with a diameter of 19 cm can use a 70 cm long plastic tree tag.

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

Common features of plastic and steel wire tags:

Both can be printed with the nursery company name, QR code of the tree, contact information, number segments, tree species, etc., and different fonts can be customized.
