Accessibility as a priority
CommerceGurus Size Guides is built with accessibility at its core, meeting Web Content Accessibility Guidelines (WCAG) 2.2 AA standards.

Take control of your store‘s accessibility
If you're selling in the US or the EU, accessibility compliance is becoming increasingly important. Individual store owners are responsible for ensuring their own storefronts comply with accessibility standards, especially regarding third-party apps.
By implementing CommerceGurus Size Guides, you're taking a significant step toward making your store more accessible while also improving the shopping experience for all customers, which ultimately leads to increased sales and satisfaction.
Business benefits of size guides

Reduces return rates and “bracketing”
By giving customers clear sizing information, you help them make informed purchasing decisions the first time. You can reduce or even eliminate "bracketing" — the common practice where customers order multiple sizes of the same item with the intention of returning those that don't fit.
Increases conversions
When customers feel confident about sizing, they're more likely to complete their purchase. CommerceGurus Size Guides removes the uncertainty that often leads to abandoned carts.
Save time and money
You can quickly make the money back in less than a day through reduced returns and increased sales. It's an incredibly affordable solution that delivers immediate value.
