19 ‘Size Guide’ Design Examples

Also referred to as: Size Chart, Measurement Chart, International Conversion Chart

What’s this? Here you’ll find 19 “Size Guide” full-page screenshots annotated with research-based UX insights, sourced from Baymard’s UX benchmark of 245 e-commerce sites. (Note: this is less than 1% of the full research catalog.)

The “Size Chart” constitutes the heart of the “Size Guide”. While both terms are often used interchangeably, the “Size Chart” is most often nested within the “Size Guide,” which may also include other sizing elements. All sizing information contained within the “Size Guide” — including a “Size Chart”, “Measuring Guide”, and an “International Conversion Chart”, among other sizing details — is crucial to helping users select their correct size for apparel products.
