Your size,
perfectly matched.
FITLD connects body measurements with brand size charts so online shoppers can choose sizes with confidence — and so retailers can reduce returns without replacing their entire stack.
Sizing is one of the biggest friction points in apparel e-commerce. We built FITLD to make it easy for shoppers to maintain one accurate profile and for brands to publish structured measurements that power consistent recommendations across web, email, and partner channels.
Built for both sides
of the size problem.
Shoppers
Create a FITLD profile with measurements taken at home. When you browse a store that uses Fitld, you see a recommended size based on that store's grading — not a generic size chart image.
Brands & Retailers
Manage catalogs, attach size data to SKUs, and call our API or embed our widget. Keep a single source of truth for measurements instead of scattered spreadsheets.
Three steps.
Perfect fit every time.
Shoppers verify their account and save measurements in centimeters or inches.
Brands upload products and size charts mapped to the measurements FITLD understands.
FITLD scores how well each size matches the shopper and returns a recommendation plus a fit-quality signal.
Built on trust,
designed with care.
Privacy by design
Measurements are sensitive. Brands receive only what they need for sizing — not unnecessary personal data.
Not medical advice
Recommendations are algorithmic comparisons against published size charts. They don't replace professional fitting or your own judgment.
Universal access
One profile, every FITLD-powered brand. Your measurements follow you across the entire ecosystem.
Measurements are sensitive. We design flows so brands receive what they need for sizing — not unnecessary personal data. Our Privacy Policy explains what we collect, why we collect it, retention, and your rights. Our Terms of Use describe acceptable use of the platform and APIs.
