Office Ergonomics

Office Ergonomics Calculator

Ensuring the proper height of your chair and workstation are crucial in office ergonomics. Having a proper workstation setup can alleviate symptoms and prevent occupational diseases such as musculoskeletal disorders (MSDs). MSDs account for 40% of all lost-time compensation claims in Ontario. Luckily, the majority of workplace risk factors that provoke MSDs, can be identified and eliminated through ergonomic interventions. This tool will attempt to reduce the likelihood of MSDs by providing you with an easy-to-use calculator, which will permit you to adjust your workstation according to your individual body measurements. 

Your Office Chair 

Your office chair is important because it serves to support your back, reduce pressure on the popliteal fold, and support your upper and lower limbs. However, when your chair is not positioned accordingly, it can cause harm to your body. The following conditions have been observed in office workers with an inadequate chair or chair setup: 

Edema

Numb and cold feet

LBP

An ergonomic chair does not protect against the eventuality of MSDs if the user does not know how to use or adjust the chair correctly. A healthy posture, induced by proper seat positioning, promotes overall comfort, increases concentration, and leads to greater endurance through long hours of seated work.

Your Workstation 

Your posture is greatly influenced by the position of your keyboard, mouse, and monitor. These affect the ability for your shoulders and neck to be placed in a neutral posture. The risk for MSDs such as shoulder tendonitis, carpal tunnel syndrome, and neck strain are decreased when the workstation is attained by ergonomic principles.

In order to work safely and comfortably, each element of your computer workstation should be adjusted to fit your needs. This calculator will provide you with a list of ideal measurements for each component of your workstation including: chair height, keyboard and mouse height, and screen height. All you need to do is enter your anthropometric information, and the current heights of your office equipment into table 1 of the excel spreadsheet. The detailed PowerPoint presentation attached will guide you in doing so. Once you have entered each measurement, Table 2 will demonstrate whether your equipment is currently too high (-), too low (+), or perfectly situated (0). Table 3 will give you ideal measurements. Use a measuring tape to ensure that your equipment is adjusted according to the ideal measurements table. If you are not able to position your equipment accordingly, you may need to purchase office equipment such as: a height-adjustable keyboard tray, chair or monitor. If you need assistance, please call an ergonomist near you.
