About Sizetab
Sizetab helps online shoe shoppers compare brand size charts before they buy. The goal is to make EU, US, UK and CM labels easier to interpret with a clear chart-based comparison and visible limits.
What Sizetab solves
Generic shoe size conversion tables are often too broad. A shopper does not only need EU to US; they need Nike to Adidas, Adidas to New Balance, or HOKA to Nike with the correct gender line and size chart context.
Sizetab focuses on brand-to-brand size decisions and keeps the limitations visible, including model differences, width, gender labels and approximate mappings.
Who it is for
The site is built for shoppers comparing shoes online, reviewers checking chart consistency, and anyone who wants to start from a measured foot length instead of guessing from a label.
It is not a medical, orthopedic or custom-fitting service. It gives a chart-based starting point and directs users to model-specific notes before checkout.
What data Sizetab uses
Official data
A row may originate from a published brand chart. Sizetab should describe it as official only when the relevant source metadata has been reviewed and stored for that chart.
Approximate mapping
Approximate data includes values that were derived, rounded, converted or otherwise transformed from the available chart information. The transformation should remain visible where it matters.
Mixed data
Mixed data combines direct chart rows with copied, derived or transformed values. The page should identify those differences instead of presenting the whole chart as one uniform source type.
