Understanding Reach Zones

The foundation of efficient space organization lies in understanding the three primary reach zones and how they relate to daily movement patterns.

What Are Reach Zones?

Reach zones are defined areas around your body where you can comfortably access items without excessive movement or strain. Understanding these zones is crucial for creating efficient, ergonomic spaces.

By organizing items according to reach zones, you minimize unnecessary movement, reduce physical strain, and create a more intuitive relationship with your environment.

Primary Secondary Tertiary

Primary Reach Zone

The primary reach zone extends approximately 15-20 inches (38-51 cm) from your body. This is the area where you can easily reach items with minimal effort and without changing your posture.

Items placed in this zone should be those you use most frequently throughout the day. This includes daily essentials, frequently accessed tools, and items critical to your primary tasks.

  • Distance: 15-20 inches from body center
  • Best for: Daily essentials, primary tools
  • Example: Computer mouse, coffee cup, phone
15-20"

Secondary Reach Zone

The secondary reach zone extends from 20 to 30 inches (51-76 cm) from your body. Accessing items in this zone requires arm extension but doesn't necessitate changes in seated or standing posture.

This zone is ideal for items you use regularly but not constantly—perhaps several times per day or week. The slight additional reach is minimal enough not to cause disruption to your workflow.

  • Distance: 20-30 inches from body center
  • Best for: Regular-use items, reference materials
  • Example: Notebooks, desk supplies, water bottle

Tertiary Reach Zone

The tertiary reach zone extends beyond 30 inches and may require standing, leaning, or repositioning. Items in this zone should be those used infrequently or seasonally.

While less convenient, this zone is perfect for archived materials, backup supplies, and items that don't need to be immediately accessible. Strategic use of this zone prevents clutter in more accessible areas.

  • Distance: Beyond 30 inches from body center
  • Best for: Occasional-use items, archived materials
  • Example: Seasonal items, backup supplies, files
