Size and Fit Questions in Chat for Shopify
Yes. AeroChat helps shoppers find the right size in the chat, with your Shopify store built in. It asks for their measurements or the size they wear in another brand, matches them to your size guide, tells them which size to pick and why, checks that size is in stock in Shopify and sends the link. It works on WhatsApp, Instagram, Messenger, web chat and every other channel.
This recipe answers “which size should I get?” before the order, so fewer items come back for fit. Part of connecting Shopify to WhatsApp and AI chat.
What happens today
Shoppers stuck between two sizes either guess, order both, or leave. Size charts help, but many don’t say whether they show body or garment measurements, and few shoppers measure anything. Each wrong guess comes back as an exchange or a return, with shipping both ways.
Your team knows that the jeans run small and the knitwear runs big. That knowledge rarely reaches the shopper before they order.
The flow that works
- The shopper asks which size to get.
- AeroChat asks for the measurements that matter for that product, or the size they wear in a brand they know.
- It matches them to your size guide and the fit notes for that product.
- It recommends a size and says why in one line, for example “this style runs small”.
- It checks that size and color are in stock in Shopify. If not, it offers the closest option or a restock alert.
- It sends the product link with the right variant.
What it looks like on WhatsApp
Customer: I’m between S and M for the Coast denim jacket. I’m 5’6″, chest 36 inches. (example)
AeroChat: For the Coast denim jacket, a 36-inch chest is an S in our size guide, but this style runs small, so most buyers your size choose M for a relaxed fit. M in washed blue is in stock. Here is the link.
Customer: Will M be too long in the sleeves?
AeroChat: M sleeves are 24.5 inches (example). If you prefer a closer fit, S is in stock too.
In Shopify: nothing changes. AeroChat read the variant and its stock. The fit advice came from your size guide and fit notes.
The recipe
Copy this into AeroChat
When a shopper asks which size to choose, follow these steps.
- Find the product they mean in our Shopify catalog.
- Ask for the measurements our size guide uses for that product, or the size they wear in a brand they know.
- Match them to our size guide. Use the fit notes in our knowledge base, such as “runs small”.
- Recommend one size and give the reason in one sentence. If they are between sizes, explain the difference in fit.
- Check that size and color are in stock. If not, offer the closest variant in stock.
- Send the product link for the variant they chose.
Never guess a measurement that is not in our size guide. Reply in the customer’s language.
Add your own fit notes for each product line before you paste it.
What to connect
- Your Shopify store. Built in. Install AeroChat from the Shopify App Store and connect your store in the dashboard. AeroChat reads products, variants and stock from your synced catalog.
- Your knowledge base. Add your size guides, garment measurements and fit notes per product line, so AeroChat answers from your own rules.
- A reviews app, if you use one. Judge.me and Okendo connect through their APIs, so AeroChat can add what buyers say about fit.
After you paste the recipe, AeroChat builds the workflow as a draft and shows a checklist of what is left: add your size guides and fit notes, then switch it on.
Using a different system? If it has a public API, it connects to AeroChat the same way: describe what you want, paste in its key, and it runs.

What you still decide
- The fit notes AeroChat uses for each product line.
- Whether it recommends one size or explains both when a shopper is between sizes.
- What it offers when the right size is sold out.
The result to expect
Shoppers order the right size the first time more often, and those who were stuck between sizes buy instead of leaving. Fewer exchanges for fit.
Measure it with your own numbers: size questions answered in chat, and returns or exchanges for fit on those orders, for a month before and after.
