Help customers find the right size before they buy — and stop paying for size-related returns

Sizing is the number one reason fashion customers return online purchases.

01

A customer orders a medium. It doesn't fit. They return it. The reverse logistics cost you ₹150–300. The replacement costs another ₹150–300 to ship. A size recommendation before purchase could have prevented both.

02

Your size chart is on your product page. Most customers don't read it — or don't know how to interpret 'chest 38 inches' into what they should order. A conversational guide does the work for them.

03

Size-related returns aren't just a cost — they're a trust problem. Customers who receive the wrong size don't always bother with an exchange. They leave a review about poor sizing and don't come back.

The solution

WhatsPortal runs a WhatsApp size assistant that helps every customer buy the right fit.

Conversational size guide

The bot asks for height, weight, body type, and preferred fit (slim, regular, relaxed) — and recommends the right size for the specific product the customer is asking about.

Product-specific recommendations

Size guides are configured per product or category. A denim recommendation considers waist-to-hip ratio. A shoe recommendation considers width. Recommendations are accurate, not generic.

Pre-purchase access

Add a 'Get size help' button or WhatsApp link on your product pages. Customers who are unsure about sizing tap to chat — and get an immediate, personalised recommendation before buying.

FAQ

Common questions about e-commerce size and fit assistant

Can the size assistant handle different categories — tops, bottoms, shoes, dresses?

Yes. You configure separate size flows for each category, each with its own measurement questions and size mapping. A shoe flow asks different questions than a tops flow.

Can the bot share size comparison charts for international sizing?

Yes. You can include size comparison information — UK, US, EU sizing — in the bot&apos;s recommendation message for brands that import or export internationally.

What if the customer&apos;s measurements fall between sizes?

You configure the recommendation logic — for example, if between sizes, recommend sizing up for outerwear and sizing down for fitted styles. The bot follows your brand&apos;s guidance consistently.

What does it cost?

Free plan: ₹0, 100 messages/month. Standard: ₹1,199/month (5,000 messages). Premium: ₹2,499/month (unlimited). All in INR via Razorpay.

Every size-related return you prevent saves you ₹300–600. Start preventing them today.
