4-9-4 Rule Calculator

The 4-9-4 Rule is a guideline in retail layout and design, which suggests optimal product placement to maximize customer attention and sales. It's based on the principle that customer attention is highest in certain areas of the store.

Historical Background

The 4-9-4 Rule originated from extensive retail research. It identifies how customers typically navigate a store and where their attention is naturally drawn. This understanding helps in effective product placement.

Calculation Formula

The Optimal Product Placement is calculated using the formula:

\[ \text{Optimal Product Placement (feet)} = \left( \frac{\text{Total Depth of the Store} \times 4}{9} \right) + \left( \frac{\text{Radius of Customer Attention} \times 4}{9} \right) \]

Example Calculation

Consider a store with the following dimensions:

• Total Depth of the Store: 30 feet
• Radius of Customer Attention: 5 feet

Using the formula:

\[ \text{Optimal Product Placement} = \left( \frac{30 \times 4}{9} \right) + \left( \frac{5 \times 4}{9} \right) = 13.3333333333 \text{ feet} \]

This means the optimal product placement is approximately 13.33 feet from the entrance.
