1/3Product overview: ratings, keeps and returns
Fewer returns, higher conversion, user content that sells.
Manually or by importing from Excel. Attach a body-measurement chart to a whole category in one click. Garment charts, measuring guides – it's up to you how much information you give your customers.
Ask customers about whatever interests or worries you most. They're happy to help you improve your products. You make them for them, after all.
Customers share their experience with products, shoppers ask those who bought before them. Your e-shop becomes a nicer place to shop.
No more guessing why over 40 % of this great jacket keeps coming back to the warehouse. After a few dozen reviews you'll see the obvious reasons in the technologist dashboard. And the rerun can have half the return rate.

What you ask most
Do customers want to share their measurements?
They do. They find out for themselves how much it helps to see the reviewer's body shape. Measurements are optional and shown only with a first name and initial.
How soon do technologists get the first data?
The survey goes out a few days after delivery – depending on your settings. So the first reviews arrive within days of the sales launch. You follow detailed fit data continuously, without waiting for end-of-season return reports that don't tell you much about the pattern anyway, do they…
Do we need a developer to deploy it?
You don't. Shoptet integration is free, and we're happy to help with other platforms. Book a demo and we'll take a look.
Can customers ask the brand, too?
Yes, customers can chat with each other or with the brand. Sizechat has advanced discussion moderation with a smart reply assistant that learns to speak your tribe's language in no time.
Is the number of measurements in size charts limited?
No. Show body or garment measurements however you need, without limits. You can tailor the measuring guide to your site's design and your products.

I have similar measurements but narrower shoulders. How does the jacket fit in the shoulders and length — does it cover your bum?
Kateřina M.It's rather loose in the shoulders but doesn't slip. It reaches below the bum, so it keeps you lovely and warm in winter. With narrower shoulders I'd go for 44.
Zuzana B.Thank you so much for the advice, I went for 44 and it fits perfectly. I've always wanted a jacket like this, it's really great.
