AI Size Recommendation for fashion brands that put fit at the heart of customer experience
Brands already improving fit and size recommendations with SizeSense






Nobody calculates size as precisely as we do.
SizeSense delivers precise size recommendations because it calculates fabric elasticity – without this factor, accurate sizing isn’t possible for fitted garments like formal wear, evening dresses, pants, and jeans.
After creating thousands of made-to-measure garments and building a deep understanding of fashion design, patternmaking, and running a brand, we realized that no existing tool accurately solves the sizing problem. That’s why we created SizeSense.
After thousands of personalized size recommendations, we’ve learned that finding the perfect fit comes down to three key factors. That’s why SizeSense takes all of them into account when recommending the right size.
Clothing design & measurements + Customer wear preferences + Fabric elasticity
SizeSense.ai Fashion Hub – Our technology

94% accurate size recommendation engine
Size Sense scores an unmatched 94% certainty on whether the product will fit properly. Additionally, our tool can advise customers on why neighboring sizes are incompatible.
How SizeSense.ai works?
- 1:1 alignment of customer body measurements with the measurements of the specific clothing being considered by your customer.
- Considers both customer body measurements and shape. This allows for a perfect fit so every customer looks great no matter their figure.
- Provides tailored recommendations considering fabric elasticity, clothing design and customer’s preferences.
Body Scanner
Customers are able to estimate their body measurements directly from an image. They can review, adjust, and save their measurements from their first interaction – making every future purchase faster and more personal.
If the user provides measurements manually, we can calculate size using only the chest, waist, hips.
But if customers upload a photo of themselves, they’ll receive a size recommendation based on their chest, waist, and hip circumference, as well as arm length, inseam, and shoulder width and height.


Virtual try-on
Yes, we’re integrating virtual try-on – but with a twist. Customers will only be able to try products that fit their measurements. Because true realism starts with the right fit.
Fit System Builder
Fit System Builder walks you through the four things that actually decide fit: body measurements, fabric stretch, ease, and construction. It helps you to create one unified system. You set the rules for your brand once, and it applies them consistently across every style — so a size M means the same thing whether it’s a woven top or a stretch legging. No more guessing, no more copying a competitor’s chart.

We analyze each garment’s measurements, cut and design to deliver a fit your customers trust

What makes Size Sense special
How the other size recommendation tools work?
Existing solutions resort to three main methods. Some analyze past customer purchases. Others match size guides across brands. A third group bases recommendations on customer data with similar height and weight profiles.
Do these methods have some statistical value? Yes.
Are they truly accurate? Absolutely not.


These methods don’t work for a reason
