E-commerce
June 28, 2026
Size issues are one of the most frequent barriers to purchase. The customer wants to know if the product runs large, small, tight, long, fits their body type, or is comparable to a brand they know.
Support must help guide the choice without promising a perfect fit for all body types.
This guide shows how to reduce hesitation related to sizes and measurements.
Summary
Why do sizes cause so much hesitation?
Two products indicated in the same size can fit differently depending on the cut, the material, the use, and the morphology. The customer knows that a return is possible, but they would prefer to avoid making a mistake.
The response must translate the size guide into useful advice.
Good size advice reduces doubt without claiming to perfectly know the customer's body.

What information should be requested?
Ask for useful measurements, usual size, reference brand, desired fit, usage, material, model, customer reviews, purchase history, and comfort preference.
The question must remain proportionate and respectful.
How do I recommend a size?
Compare the product measurements to the guide, then indicate the trade-off: tighter, more comfortable, longer, shorter, or more suitable for the use. If two sizes are possible, explain the choice criteria.
The customer must understand why a size is recommended.
How to manage uncertainty?
If the information is not sufficient, say so clearly and suggest the most helpful action: measure a similar garment, consult reviews, choose according to the desired fit, or check the exchange policy.
It is better to be cautious than to promise a perfect size.
When the recommendation depends on a personal preference, such as wearing it loose or fitted, the support must say so explicitly. Two customers with the same measurements may choose two different sizes depending on the desired look.
How to enrich product sheets?
Add a size guide, product measurements, fit details, photos of the item being worn, the model's size, fit reviews, and return rates by size if available. The chatbot can leverage this information during the conversation.
Support should flag matches that generate many size exchanges.
Size data must become more concrete.
It is also useful to indicate how to measure correctly: chest circumference, waist, hips, inside leg, or measurements of a garment already worn. A reliable recommendation often depends on a measurement taken in the right place.
Size advice must make measuring accessible.
Which flow to follow?
The flow must guide without overpromising.
Identify the product, target size, body measurements, usual size, fit, and usage.
Check the size guide, product measurements, material, reviews, history, returns, and stock.
Recommend a size with the reason and level of uncertainty.
Propose an alternative, explain the exchange process, save the choice, transfer, or document.
Measure size-related questions, conversion, exchanges, returns, satisfaction, and high-risk models.
Which examples should be used?
“If you prefer a close fit, choose your usual size; for a looser fit, go one size up.” “This model is longer than our standard fit.”
The answer should help the customer decide.
When to transfer?
Transfer is necessary for custom-made products, high value, specific morphology, very hesitant client, urgent event, history of repeated exchanges, or uncertain recommendation.
The bot must transmit the product, measurements, preferences, compared sizes, stock, and risk.
Which KPIs should be monitored?
Track size questions, assisted conversions, exchanges, returns, fit reasons, most returned sizes, customer reviews, and satisfaction.
This data improves guides.
Which mistakes should be avoided?
Avoid guaranteeing a perfect fit, asking for too much personal information, ignoring the cut, hiding frequent returns, or giving a recommendation without measurements.
The advice must remain honest.
How can Qstomy help?
Qstomy can connect the chatbot to Shopify, orders, accounts, pre-orders, products, videos, size guides, returns, exchanges, inventory, shipping carriers, and escalation procedures to answer accurately.
The chatbot helps the customer understand a migration, a pre-order, a product seen in a video, a size or an exchange without making up a date, inventory level, compatibility, recommendation, or promise that needs to be verified.

Key takeaways
Key Takeaways
Sizing questions must clarify guides, measurements, cut, material, reviews, exchanges, uncertainty, and recommendations.
What the Customer Needs to Understand
The customer must choose a size with greater confidence, without false guarantees.
The Chatbot's Proper Limit
The chatbot can recommend and explain, but it must transfer requests for custom-made items, high-value cases, emergencies, and highly uncertain situations.
