GetSizeOS

The operating system
behind perfect fit

Running the retail-independent sizing platform that works across 100+ brands and every retailer. One data layer. Zero guesswork.

100+ Brands mapped
$45B Returns problem
0 Measuring tapes needed
The problem nobody owns

A US 9 is not a US 9

25-30%

of shoes bought online get returned. Half of those are size-related. The sizing layer between brands and customers is fundamentally broken.

52%

of all apparel returns cite sizing. Every incumbent locks their solution inside a single retailer. Nobody solved it for the shopper who buys across stores.

How it works

Sizing intelligence,
built independently

01

Digital Shoe Shelf

Users add shoes they already own that fit. Each pair teaches the system about their unique fit profile across brands, widths, and preferences.

02

Cross-Brand Comparison

Search any shoe from 100+ brands. The platform compares it against the user's shelf and fit data from thousands of similar profiles.

03

Real Fit Data

Not AI foot scans. Not measuring tapes. Real-world fit data from people who actually wear the shoes, combined with manufacturer specifications.

04

Retail Independent

Works across every retailer because it was built outside of them. One neutral source of sizing truth, not locked behind any storefront.

The data advantage

Every recommendation makes the next one smarter

GetSize sits on a growing dataset of cross-brand fit intelligence. Official size charts mapped to every model. Crowdsourced fit data from real users. The more people use it, the more accurate it gets, and the harder it becomes to replicate.

True Fit has 65% market share in B2B sizing. Nobody owns consumer-side, cross-retailer sizing. That gap is the opportunity.

Brand coverage
Fit accuracy
User growth
Data defensibility

The internet solved search, payments, and logistics.
Sizing is still broken.

GetSize is building the sizing layer the internet forgot. One neutral, independent platform where every shoe from every brand fits right the first time. Stockholm-built. Globally useful.
