Reduce fit uncertainty. Increase conversion.

Harvard Business School field experiments and peer-reviewed research show: when shoppers know their size fits, they stop hesitating and buy — with higher order values and fewer returns.

Bigger order value, less returns

HBS researchers randomly assigned online shoppers to see fit information (including a size recommendation) vs. not. Those who received it converted more, ordered more, and returned less.

Harvard Business School (2018)

Fit uncertainty kills purchase

Peer-reviewed research consistently shows that perceived fit uncertainty is a key barrier to online purchase. When shoppers can't judge whether a product will fit, they hesitate, abandon, or over-order.

Frequently asked questions

Does this work on mobile?

Yes. The flow is optimized for modern mobile browsers and desktop devices.

Can we keep our own size table?

Yes. You can keep your existing sizing logic and map recommendations to your catalog.

How fast is the result?

Most measurements complete in a few seconds after capture quality is sufficient.

How much does it cost?

Pricing is tailored to your brand's volume and needs. After a free demo call, we'll prepare a custom quote.

How accurate is the measurement?

Accuracy is ±1 cm in 90% of cases, comparable to measuring with a tailor's tape, where pressure, position, and technique also affect the result. Our system automatically detects problematic conditions such as glasses, poor lighting, or a wrong angle and prompts the customer to re-measure.

Do we need our own developers for integration?

No. Just insert a one-line script or give us access and our integration specialist handles the rest. We'll also need your product feed with size charts so we can map measurements to specific products.

What happens to customer data?

No photos or videos are stored. Face mapping runs on the customer's device. Data does not leave the device except for LLM inference, where it is neither stored nor used for training.

Which e-commerce platforms are supported?

All of them. Just add a JS snippet and provide a product feed, whether you use Shopify, WooCommerce, Prestashop, Magento, or a custom solution.

What if a customer denies camera access?

The technology is camera-based, so it cannot work without it. In that case, the customer can use the standard size chart on your website and measure manually.

Can we see usage statistics?

Yes. The dashboard tracks started and completed measurements and breaks them down by product. Your own e-shop metrics, such as returns and conversions, remain in your existing tools.

Can we customize the look to match our brand?

Yes. By default you can set colors and your own logo. For more specific requirements, we can develop a fully customized solution.

What languages is the measurement available in?

Any language. If we don't support one out of the box, we can deploy it promptly.

Do you plan measurement for other body parts?

Yes. Tools for measuring other body parts are planned and will be listed as separate products.
