Built to remove every reason not to buy
Other sizing tools add friction, ask for downloads, or send customer photos to a server. UniMeasureAI was designed to do the opposite.
No app to download
Runs directly in the browser on any phone, tablet or laptop. Nothing to install — the customer just clicks and measures.
Photos never leave the device
Images are processed on the customer's own device and are never uploaded or stored. Only the measurement data is used to recommend a size.
Multiple sizing use cases
One platform for body, foot, head and hand — apparel, footwear, helmets, gloves, made-to-measure and specialist gear.
High accuracy
Measurements are continuously validated against references and monitored per measurement type for accuracy and repeatability.
Low friction
A guided measurement takes seconds. No tape measure, no manual size-chart reading, no leaving the product page.
Measured, not guessed
Sizes come from real, camera-based measurements rather than rough estimates — so customers get the right fit the first time, with accuracy validated across every measurement type.
Now available on Shopify

Sizing uncertainty affects both conversion and returns
Choosing a size is one of the few moments in online shopping where customers are often expected to make a decision with incomplete information. Traditional size charts help, but they usually require the shopper to know their own measurements — and those measurements may not translate directly between brands and products.
Common Challenges
-
Sizing varies between brands and products
A medium is not a universal measurement. Customers often have to reinterpret sizing every time they shop with a new brand.
-
Uncertainty can stop a purchase
When shoppers are unsure which size to choose, they may delay the purchase, abandon the basket or order several sizes.
-
Returns reduce margin
A size-related return creates more than a refund. It can also involve shipping, warehouse handling, customer service, inspection, repackaging and delayed resale.
-
Returns create avoidable environmental activity
Every unnecessary return means additional transport, handling and packaging.
Give customers a better way to choose
-
Camera-based measurements
Customers capture the measurements relevant to the product using their own device camera.
-
Your own sizing logic
UniMeasureAI uses your size charts instead of forcing your products into a generic universal sizing system.
-
Personalized recommendation
Each shopper receives guidance based on the relationship between their measurements and the size information for the product.
-
Built into the shopping journey
The process runs directly in the browser, helping customers make a sizing decision without leaving your webshop.
Turn sizing uncertainty into purchase confidence
Size charts often require customers to know their own measurements, while sizing can vary significantly between brands and products. UniMeasureAI gives shoppers a simpler way to choose.
Using their own device camera, customers capture the relevant measurements in seconds. UniMeasureAI then compares those measurements with your size charts and recommends the most suitable size.
The result is a smoother buying experience designed to increase confidence at the point where many customers hesitate: choosing a size.
Need a custom integration?
UniMeasureAI can also be integrated directly into other e-commerce platforms and custom webshops through API integration.

The founder
Simon Scheibel is the founder of UniMeasureAI, an AI-powered sizing and measurement platform for e-commerce.
Based in Copenhagen, he started UniMeasureAI to tackle one of online retail's most stubborn problems: shoppers who can't tell which size will actually fit them.
UniMeasureAI lets customers capture body, foot, head and hand measurements with their own device camera, then matches them to each merchant's own size charts — no tape measure, no separate app, no guesswork.
“A size should be a decision customers make with confidence — not a guess they hope they got right.”Read Simon’s full story
