Reduce Returns with Size Suggestions: E-commerce Satisfaction Guide

In the e-commerce world, size selection is the main source of customer dissatisfaction and return rates. According to research, 60-70% of returns in the apparel and footwear category are due to "size not fitting." This situation causes serious losses for businesses, not only in logistics costs but also in customer churn.

            💡 Critical Fact: If your e-commerce site sells apparel, the weakest point of customer experience is size recommendation. This gap directly impacts your business's profit margin.
          

The Financial Impact of Returns: The Cost of Sizing Errors

Costs Generated by Return Rates

The average cost of a return for an e-commerce business is 10-15% of the sale. If this rate increases to 20-25% due to size selection:

💰 Shipping cost (return): Average 50-100 TL per product
📦 Inventory and warehouse management: Reprocessing returned items
🔄 Exchange processing: Time lost by customer service
💸 Lost sales: Returned customers are 30% less likely to shop again

For these reasons, a 10% reduction in return rates can lead to a direct 3-5% increase in profit margins.
