8 basic ergonomic principles

8 basic ergonomic principles

Adjustability is a key factor in creating a truly ergonomic workstation. Just as important is how easily those adjustments can be made—effortless changes help maintain productivity and comfort throughout the workday.
This guide outlines eight core ergonomic principles for effective workstation setup, developed by ergonomic specialists at AME System to help you enhance worker efficiency, safety, and motivation.

Guide to workstation configuration

Each Job Is Different. Each Worker Is Different.

Worktop Height

The height of the work surface must accommodate users of varying body sizes to support proper posture and reduce strain.

Design Guidelines:

Ensure adequate freedom of movement beneath the worktop: minimum 600mm footroom and 400mm legroom.

Avoid installing tool drawers, keyboard trays, or other obstructions between the benchtop and the user's upper thigh.

 

Adjust Work Surface Height to Match the Task

Work Surface Height
The appropriate benchtop height depends on the size of the item being handled.

  • Large objects require a lower work surface to allow for clear visibility and reach.

  • Small components are better suited to a higher work surface for precision tasks.

If the benchtop is too low, workers may lean forward to see their work clearly—leading to poor posture and increased strain on the back, neck, and shoulders.

Recommended Sitting Positions:

  • Forward: Ideal for tasks that require force, such as heavy assembly.

  • Central: Best for fine assembly, handling small components, or testing.

  • Rear (slightly reclined): Suitable for monitoring or quality control tasks.


Alternate Between Sitting and Standing

Varying Work Position

Ergonomists recommend alternating between seated and standing positions throughout the workday.
This variation helps relieve muscle fatigue, improve circulation, and reduce the risk of repetitive strain.

Smart Height Adjustability

AME System’s electric height-adjustable workstations support these changes seamlessly—enabling fast, effortless transitions at the press of a button.

A dynamic workstation setup becomes a natural extension of the user’s body—enhancing both comfort and productivity.

Work Below Heart Level

Posture and Positioning for Seated Work

Maintain an upright posture with the lower back supported by the chair’s lumbar support.

Ensure feet are flat on the floor or footrest to promote circulation and reduce fatigue.

Avoid Elevated Work Positions

Keep workpieces below heart level to maintain healthy blood circulation.

Working above this height reduces blood flow, leading to rapid fatigue and decreased performance.

Avoid holding items in static positions for long periods.

Reduced muscle circulation leads to tiredness, impaired coordination, and lower-quality output.

Reach Comfortably for Objects

Most tasks should be performed on the flat surface directly in front of the operator. To minimise strain and maximise efficiency, items should be positioned within defined reach zones:

Area A – Primary Reach Zone

  • Contains tools and components used most frequently

  • Should be accessible without moving the upper arm significantly

  • Designed to reduce muscle stress and optimise workflow

Area B – Secondary Reach Zone

  • For items often retrieved with one hand

  • Requires shoulder and elbow movement, but no torso rotation

  • Suitable for moderately frequent tasks

Area C – Tertiary Reach Zone

  • Requires full arm extension and some trunk movement

  • Less efficient due to greater physical effort and repositioning

  • Items used infrequently can be stored here, but avoid placing any beyond this area

Parts containers or tools should not be placed outside the defined reach zones, as this negatively impacts posture, coordination, and performance.

Position Parts Within the Optimum Field of Vision

Visual ergonomics are as important as physical posture.
The workstation should support a natural head position to minimise eye strain and improve efficiency.

Recommended Head Angles:

  • 15° downward for seated work

  • 25° downward for standing work

Design Guidelines:

  • Position containers and displays at a consistent distance to reduce excessive head or eye movement

  • Avoid setups that cause repeated re-focusing or visual tracking across varying depths

Field of Vision A

  • This is the primary visual zone

  • Frequently used components and visual indicators should be placed here for immediate visibility without unnecessary movement

Maintaining a consistent and natural line of sight supports concentration, reduces fatigue, and enhances task accuracy.

Adjust Shelves to Minimise Reach

Efficient use of space often goes beyond the horizontal work surface—vertical shelving can significantly expand available storage and improve workflow.

Recommended Shelf Zones:

Zone A – High Priority Items

  • Shelves in this zone should hold the most frequently used tools and components

  • Position them within easy reach to minimise unnecessary movement

Zone B – Short-Term Equipment

  • Items that are used occasionally or for short periods can be stored here

  • Shelves in this zone can be slightly further away but should still be accessible without excessive stretching

Zone C – Low Priority Area

  • This zone can be used for items not frequently needed

  • To reduce strain, extend upper shelves closer to the operator or tilt them downwards towards the work surface for easier access

Optimising shelf placement ensures less reaching and better overall ergonomics, reducing strain and improving task efficiency.

Place Your Work Where You Need It

Position trolleys, shelves, and other work aids within easy reach, ensuring they are angled to enhance accessibility and minimise unnecessary movement.

Optimising Workspace Positioning:

  • Ensure all tools, materials, and equipment are placed where they are most needed to reduce the need for excessive reaching or bending

  • Adjust working aids such as trolleys and shelves to maintain an ergonomic posture, keeping them within comfortable reach

Chair and Footrest Positioning:

  • Ensure your chair and footrest are correctly adjusted to support a natural seated posture and reduce strain

Benefits of Proper Adjustment:

  • Correctly positioned tools and equipment help maintain a fatigue-free posture

  • Well-adjusted working aids improve productivity, reduce downtime, and minimise strain on the body
