What Is Standard Tripod Thread Size? The Ultimate Guide

A tripod thread is a screw that attaches a camera or other equipment to a tripod. It is an essential component for capturing stable, sharp images and videos. Understanding the standard tripod thread size is crucial because it ensures that the camera or equipment is compatible with the tripod and prevents it from being damaged.

The Standard Tripod Thread Size

The standard tripod thread size, 1/4-20, means that the thread’s diameter is 1/4 inch, and the pitch, or distance between threads, is 20 threads per inch. This size is commonly used for attaching cameras, smartphones, and other devices to tripods, but it is not the only size available. Other sizes include 3/8-16, 5/8-11, and 1/2-13, but these are less common and mainly used for larger equipment.

History of the Tripod Thread

The tripod thread has evolved over the years to accommodate the growing needs of photographers and videographers. In the early days, the tripod thread was not standardized, and different cameras and equipment had different screw sizes. This created problems when attaching different devices to the same tripod, leading to adopting a standard size.

The standard size was established to provide compatibility between different types of cameras and equipment, making it easier for photographers and videographers to switch between devices without worrying about compatibility issues. The standard tripod thread size is known as the “1/4-20” size and refers to the thread’s diameter and pitch, respectively.

Compatibility with Different Cameras and Equipment

The 1/4-20 standard tripod thread size is widely used and is compatible with most cameras and other equipment. However, checking the device’s specifications before purchasing a tripod is essential to ensure compatibility. Some devices may have a different size or require an adapter to be used with the standard tripod thread size.

How to Measure the Tripod Thread Size

Measuring the tripod thread size is straightforward and can be done with a few tools. To measure the thread size, you will need a caliper, a ruler, or a screw gauge.

Step-by-Step Guide to Measuring the Thread Size:

Using a caliper to measure the diameter of the thread or using a ruler to measure the diameter of a caliper is not available.

Count the number of threads in one inch of the screw using a ruler or a screw gauge.

Record the diameter and pitch measurements, which will give you the thread size in the format of “diameter-pitch.”

Common Mistakes to Avoid

When measuring the tripod thread size, it is essential to ensure that the measurements are accurate. Some common mistakes to avoid include the following:

  • Measuring the diameter of the screw head instead of the thread.
  • Miscounting the threads.
  • Measuring the pitch with a ruler that is not calibrated correctly.

Tripod Adapters and Alternatives

Sometimes, a tripod may have a thread size different from the camera or equipment you use. In such situations, a tripod adapter can be used to provide compatibility. Tripod adapters come in various sizes and can convert a larger thread size to a smaller one or vice versa.

Another alternative to using a tripod is to use a flexible tripod that can be attached to a camera or device using a standard tripod screw or a clamp that can be attached to the device without needing a screw.


The standard tripod thread size of 1/4-20 is widely used and is compatible with most cameras and other equipment. Understanding the standard size is important for ensuring that the device is compatible with the tripod and preventing damage to the equipment. Measuring the thread size is simple and can be done with a few tools, and there are alternatives, such as tripod adapters and flexible tripods, that can be used if compatibility is an issue.

In conclusion, understanding the standard tripod thread size is essential to being a photographer or videographer. You can achieve stable and sharp images and videos by ensuring compatibility between the camera or equipment and the tripod; whether a professional or amateur, taking the time to understand this aspect of photography and videography can help you get the desired results.
