Category: Gardening

A straight trellis needs end posts as well as intermediate supports and wire levels.

Measure the row and enter maximum post spacing. Compare the counted posts and horizontal wire lengths.

## Inputs and controls

* Row length (m). Allowed range: 0.01 to 1000
* Maximum post spacing (m). Allowed range: 0.01 to 100
* Horizontal wire levels (levels). Allowed range: 1 to 100
* Extra wire per level (m). Allowed range: 0 to 1000
* Wire roll length (m). Allowed range: 0.01 to 10000
* Price per roll (PKR). Allowed range: 0 to 100000000

## How to use

* Enter row length, maximum post spacing and horizontal wire levels.

* Enter extra wire per level, wire roll length and price per roll.

* Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

The endpoint rule helps prevent a materials list from missing one end of the row.


## Before relying on the result

Counts include both end posts. Quantities do not certify strength, wind resistance or anchoring.


## Tool limitations

Counts include both end posts. Quantities do not certify strength, wind resistance or anchoring.

## Questions

### Does the count certify strength?

No. Wind, loads, anchoring and support specifications need separate design review.

### What should I check before using Trellis Materials Calculator?

Check Row length, Maximum post spacing, Horizontal wire levels and Extra wire per level. Use the exact units shown beside the controls and replace any example values with your own inputs.
