Safety Harness Size Calculator

Selecting the right size safety harness is crucial to ensure the safety and comfort of individuals working at heights or in challenging environments. Wearing an ill-fitting harness can lead to discomfort, reduced mobility, and, more importantly, it may not provide the necessary protection in case of a fall. To assist you in choosing the appropriate safety harness size, we’ve developed a Safety Harness Size Calculator along with the formula and guidelines.

The Formula for Safety Harness Size Calculator

The size of a safety harness is typically determined by a combination of the individual’s height, weight, and chest measurements. The following formula can be used to calculate the ideal safety harness size:

Harness Size (inches) = Height (inches) + Weight (pounds) + Chest (inches)

Step-by-Step Guide

To use the Safety Harness Size Calculator effectively, follow these steps:

1. Measure Height

Measure the individual’s height in inches. This measurement should be taken from the top of the head to the floor while the individual is standing straight.

2. Measure Weight

Weigh the individual in pounds using a reliable weighing scale. Ensure that the individual is wearing the typical clothing and equipment they would wear while working.

3. Measure Chest

Measure the individual’s chest circumference in inches. To do this, wrap a measuring tape around the chest at the widest point, typically just under the armpits.

4. Calculate the Harness Size

Now, plug the values obtained in the above steps into the formula:

Harness Size (inches) = Height (inches) + Weight (pounds) + Chest (inches)

5. Compare to Manufacturer’s Size Chart

Different manufacturers may have variations in their sizing recommendations, so it’s essential to compare the calculated harness size to the manufacturer’s size chart. Choose the harness size that falls within the recommended range for a safe and comfortable fit.


Selecting the correct size safety harness is a critical aspect of ensuring safety and comfort for individuals working at heights. Using the Safety Harness Size Calculator, along with the provided formula and guidelines, will help you determine the right fit, reducing the risks associated with improper sizing and enhancing the overall safety of workers in elevated or hazardous environments. Always remember that safety is paramount, and a well-fitted harness is a fundamental component of that safety.
