What is the Length of PVC Conduit: A Comprehensive Guide

what is the length of pvc conduit


PVC conduit is a popular choice for electrical installations due to its durability and versatility. One important aspect to consider when using PVC conduit is its length. In this comprehensive guide, we will explore the various lengths of PVC conduit available and how to choose the right length for your project.

Standard Lengths

PVC conduit is typically available in standard lengths ranging from 10 feet to 20 feet. These lengths are commonly used in residential and commercial applications. The most common standard length is 10 feet, which is suitable for most projects. However, longer lengths such as 20 feet are often used in larger installations where fewer joints are desired.

Custom Lengths

In addition to standard lengths, PVC conduit can also be custom cut to specific lengths. This is particularly useful when dealing with unique project requirements or when working in tight spaces where shorter lengths are needed. Custom lengths can be easily achieved by using a PVC conduit cutter or a hacksaw.

Factors to Consider

When determining the appropriate length of PVC conduit for your project, there are several factors to consider:

1. Distance: Measure the distance between the electrical boxes or devices that the conduit will connect. This will help determine the total length of conduit needed.

2. Bends and Turns: Take into account any bends or turns that the conduit will need to make. These will require additional length to accommodate the curvature.

3. Expansion and Contraction: PVC conduit expands and contracts with temperature changes. Allow for some extra length to account for this movement and prevent stress on the conduit.

4. Accessibility: Consider the accessibility of the conduit for future maintenance or modifications. If the conduit is located in a hard-to-reach area, it may be beneficial to use longer lengths to minimize the number of joints.


In conclusion, the length of PVC conduit plays a crucial role in electrical installations. Standard lengths ranging from 10 feet to 20 feet are readily available, but custom lengths can also be obtained. When choosing the appropriate length, consider factors such as distance, bends, expansion, and accessibility. By carefully considering these factors, you can ensure a successful and efficient PVC conduit installation for your project.
