The Sizing Problem in Online Retail

As mentioned in the beginning, when shopping for fashion online, customers face the

challenge of finding the right size. Size charts provided by brands can be helpful, but they often lack accuracy and consistency across different products and manufacturers. As a result, customers may order the wrong size, leading to frustration, increased return rates, and potential loss of business. All these sizing issues can negatively impact customer satisfaction and affect the bottom line. It's essential to find ways to help customers accurately determine their size to reduce returns and improves the overall shopping experience.

The Impact of Returns on Online Retailers

As much as customers dread the uncertainty of online sizing, retailers face their own set of challenges. High return rates can be detrimental to online retailers, leading to increased costs and logistical challenges. As an online retailer, you must consider the impact of returns on your company's operations and profitability.

Some consequences of high return rates include:

  • Loss of revenue: When customers return items, the retailer loses the revenue from those sales, leading to decreased profits.
  • Increased operational costs: Processing returns requires additional resources, including labor, shipping, and restocking costs.
  • Damaged reputation: A high return rate may result in negative customer reviews and damage the retailer's reputation, which can hinder future sales.
  • Low customer satisfaction and decreased loyalty: Returns frustrate customers and erode their trust in the brand. This ultimately leads to lower customer satisfaction, decreased loyalty, and a decrease in the lifetime value (LTV) of customers. It creates a ripple effect throughout the business, requiring higher re-marketing spend to win back customers and hindering organic growth.
  • Environmental impact: Shipping items back and forth contributes to increased carbon emissions and waste.

Potential Solutions for Sizing Challenges

To tackle the sizing challenges in online apparel and footwear retail, several potential solutions can help improve the customer experience and reduce return rates.

  • Enhanced brand and category-specific size charts: For multi-brand retailers, implementing brand and category-specific size charts can address the variations in sizing across different brands and products. Solutions like “Dynamic Size Guides” from Fit Predictor can ensure that customers have accurate size information tailored to each brand and category they are browsing.
  • Customer reviews, feedback, and Fit Predictor: Encouraging customers to leave reviews and share their sizing experiences might help. Incorporating this feedback into product descriptions and size charts can enhance accuracy. Additionally, leveraging tools like Fit Predictor, which uses advanced algorithms to provide personalized size recommendations, can assist customers in finding the right fit, especially when they are unfamiliar with different size systems.
  • Virtual fitting tools: With advances in technology, virtual fitting solutions have become increasingly popular. These tools enable customers to visualize how clothing and footwear items will fit, taking into account their measurements or information about their sizing in other brands. Integrating virtual fitting tools into the online shopping experience can provide a personalized and interactive way for customers to choose the right size.
  • Comprehensive sizing guides for a diverse customer base: In the modern retail landscape, where customers come from diverse geographies and cultures, retailers can create comprehensive sizing guides. These guides can include instructions on how to measure oneself accurately, tips for choosing the right size, and explanations of different sizing systems used in the US, UK, EU, Latin America and Asia. By acknowledging the significance of inclusivity and considering the needs of various markets, retailers can ensure their sizing guides cater to extended sizes and body types, providing a more inclusive experience for all customers. This is particularly relevant in addressing concerns raised by customers from different continents, who may have specific fit considerations when purchasing European products, for example. By offering clear and informative sizing guides that account for global sizing variations, retailers can empower their customers to navigate the complexities of sizing and make confident purchase decisions.
  • Excellent customer support: Providing easily accessible and knowledgeable customer support is essential in addressing customers' sizing concerns. Having dedicated support teams available to assist customers with sizing inquiries and provide guidance on selecting the right size contributes to a positive customer experience.

By implementing these solutions, online retailers can improve the accuracy of size information, alleviate customer frustrations, and reduce return rates. Tailoring size charts, leveraging customer feedback, utilizing virtual fitting tools, providing comprehensive sizing guides, and offering excellent customer support collectively enhance the overall customer experience and contribute to increased customer satisfaction.


The impact of high return rates go beyond the immediate financial and operational costs. It also affects customer satisfaction, loyalty, and the long-term success of the business. By minimizing returns through improved product descriptions, accurate sizing information, and personalized recommendations, retailers can enhance customer satisfaction, build trust, and increase the lifetime value of their customers. Additionally, adopting sustainable practices such as eco-friendly packaging and reducing carbon emissions further aligns the business with environmentally conscious consumers.
