Trex Fencing Estimator
Use our fencing estimator to determine exactly how much fence you will need for an installation:
- Provide the appropriate dimensions for the fencing project.
- Stake out your fence perimeter using the click and drag tools.
- Customize your fence by selecting gates, fence color and style of post caps.
The fencing estimator will display a printable list including the type and quantity of parts needed to build the fence.
