How to read a fence label
September 9, 2025
If you’ve ever shopped for rural or farm fencing, then it’s likely you have come across a product label that looks likes this – 7/90/30 400m.
At first glance, it might look like a random combination of numbers, but this label actually tells you everything you need to know about the fence. These numbers are a quick and easy way to identify the unique features of each roll of fence and helps you make your selection for your property.
Breaking down the label
First Number
The first number on the label tells you how many horizontal wires – or lines wires – run through the fence. For example, the 7 in 7/90/30 means there are 7 horizontal wires stacked from top to bottom in the fence.
Second Number
The second number on the label tells you how high the fence is in centimeters. In this case, the 90 in 7/90/30 means the fence is 90cm high.
Third Number
The third number on the label indicates the space between the vertical or picket wire. This is the wire that holds the line wires in place. The 30 in 7/90/30 means there are 30cm intervals between the vertical wires.
Fourth Number
The fourth number on the fencing label is the length of the entire role of fencing wire. In this example, 400m means that there is 400m of fencing on the roll. This makes it easy to calculate how many rolls you’ll need for your project.
