When it comes to installing things in the house such as projectors, TVs, audio, And video systems, the most often asked question that homeowners ask today is what the ideal size of conduit for HDMI cable installation is. 

There are basically two types of HDMI cables: there is the HDMI standard and the High-speed HDMI standard. The HDMI standard is the most common. All of these standards also have a variety of different variations.

So, how big of a conduit for HDMI cables?

As a general guide, the 3/4-inch conduit or the 1 ½  HDM conduit in diameter is better than the standard HDMI conduits. They fit in with most HDMI cables and are easy to set up. 

Nonetheless, when it comes to selecting the conduit size for your HDMI cables, it is important to understand that there is no specific conduit size for HDMI cables. There are a variety of sizes available to choose from. 

Take, for example, the 3/4-inch conduit or even a conduit that is 11/2 inches in diameter. The whole process of selecting a conduit will be determined by the design and brand of the HDMI cables that you want to use, as well as your budget. 

This is due to the fact that not all HDMI cables are made equal and, as a result, they may have varying portends on them.

Additionally, while selecting your conduit diameters, you may want to consider the potential of future expansion. 

For example, if you are certain that you will be making modifications in the future, you should choose conduit sizes that will enable you to perform the changes without encountering any complications in the process.

To put it another way, if you are putting your HDMI cables via a PVC conduit, you should consider using a conduit size of 11/2 inches or more. This has to be big enough to support greater runs in the future.

If you have a very large conduit, it is preferable to have a small conduit since the larger conduit will enable you to upgrade if necessary, however, the smaller conduits will cause you troubles if needed to update.

What sizes of conduits may accommodate HDMI?

There is no set standard for the diameters of conduits, as has been previously stated. Therefore, based on numerous criteria, you may choose to route your HDMI cable via a conduit that you deem appropriate for your HDMI cable. 

When connecting an HDMI cable in a 1 inch PVC conduit or perhaps a 3/4 inch conduit, you must make sure that no other cables or cords are flowing through the conduit at the same time.

If you run an HDMI cable in a 3/4 inch conduit, you can end up having difficulties since HDMI cables have a very broad end that is nearly 3/4 inch in diameter. As a consequence, larger conduit diameters, such as 11/2 inch, are preferred.

 However large or small your home is, it is critical that you have adequate room to expand if the need arises later on.

Running your HDMI cable in a Conduit

Using glass fiber tape is the most effective method of feeding your cable via the channel/conduit. This is because of the flexibility that allows it to go around curves while being firm enough even to move through them easily.

When it comes to pulling the cables, you need to make sure that you carefully put the tape through till it emerges from another end before starting. 

Next, attach one end of the cable to another end of the cable and keep pulling the tape till the HDMI cord is pulled through once again.


To prevent the cable from becoming tangled, tape the bends of the connection together. If it becomes stuck, make sure to not pull it too hard; rather, wriggle it until it becomes unstuck.


There are two kinds of HDMI cables. Unlike the high-speed HDMI specification, which offers a resolution that is very high such as 4K Ultra HD. On the other hand, the HDMI standard offers low-resolution output. 

In order to install your HDMI cables, one of the most important steps you must do is to route the wire via a conduit. 

As a result, understanding the size of the conduit that will be required is an essential element of the installation. 

Knowing what things to take into consideration when selecting the size of your conduit is very important.
