Free Online Ring Sizer for Jewelry Stores
Help every customer find their perfect ring size before checkout and reduce returns with the Keyideas Ring Size Adjuster.
Contact UsKnow Every Ring Size Before You Sell
The Keyideas Ring Sizer is a free app that helps jewelry shoppers find their accurate ring size directly on your product pages.
Available on Shopify and WooCommerce, the online ring sizer widget integrates into any jewelry product page without requiring coding skills.
Shoppers measure their ring size in two ways: by measuring their finger directly on screen using the device’s calibrated display, or by placing an existing ring on screen and adjusting the on-screen guide to match the ring’s inner diameter.
The ring size adjuster displays a clear conversion table covering US, UK, Australian, European, and Japanese ring size standards, plus fit preference options including Snug, Balanced, and Comfort.
Giving customers confidence in their ring size before checkout reduces hesitation, increases conversion rates, and cuts down on size-related product returns.
Keyideas has built jewelry digital tools and apps trusted by hundreds of jewelers across the United States, United Kingdom, and Australia.

How Accurate Sizing Reduces Returns
The Ring Sizer offers two calibrated on-screen methods: shoppers either adjust a slider to match their finger span, with a separate knuckle difference control for wider-knuckle fingers, or place an existing ring on the screen and align it to the circular guide for a diameter reading. Results display across US, UK, European, Italian, and French sizes with Snug, Balanced, and Comfort fit preferences, giving buyers accurate sizing before checkout and cutting size-related returns for the store.

Free Install from the Shopify App Store
Widget Placement on Product Pages
Brand Styling and Display Customisation
Available free from the Shopify App Store, the Ring Sizer installs without developer involvement and is configured entirely through your Shopify admin. The widget adds a size guide button to the product pages you choose, opening in a modal so shoppers complete the measurement without leaving the page they were browsing. Button text, colors, and size chart labels can be adjusted to align the tool’s appearance with your store’s brand identity.
Ring Sizer for WooCommerce Jewelry Stores
Free Plugin from the WordPress Directory
Category-Level Widget Display Control
Plugin Styling and Dashboard Configuration
The Ring Sizer is available free from the WordPress plugin directory and activates through the standard plugin process with no custom coding required. After installation, store owners choose which product categories display the widget, so it appears on ring pages without showing on pendants, earrings, or other non-ring items. Button styling, modal layout, and size chart preferences are all controlled from the plugin settings panel inside your WordPress dashboard.
Ring Builder for Custom Jewelry Creation

Pendant and Earring Configuration
Diamond Selection Across Shape, Carat, and Grade
The Keyideas Ring Builder guides shoppers through the full configuration of a custom engagement ring, selecting a diamond by shape, carat, cut, color, and clarity before pairing it with a compatible setting from the store’s collection. The same guided process extends to pendant and earring builds, giving retailers a personalized creation experience across multiple product categories that increases average order value and deepens the buyer’s commitment to the product before checkout.

Attribute-Based Filtering for Diamond and Ring Categories
Intelligent Search Across Large Catalogs
Improving Conversion Through Better Product Discovery
The Keyideas Filter and Search app replaces generic platform collection filtering with a jewelry-specific discovery experience built around how ring and diamond buyers actually search. Shoppers narrow large inventories by shape, carat, metal type, gemstone, and price range using attributes the store owner configures. Intelligent search and structured category navigation complement the filters, helping buyers reach the right product quickly from any catalog size and reducing the drop-off that browsing frustration causes.

How Visual Transparency Increases Purchase Confidence
Jewelith lets shoppers design rings, bracelets, and necklaces in a browser-based 3D studio, choosing metal type, stone shape, color, and setting style and seeing every selection reflected immediately in a three-dimensional preview from multiple angles. Unlike dropdown-based configuration where the buyer guesses the outcome, Jewelith makes the finished product visible before checkout, increasing purchase commitment and reducing the post-delivery uncertainty that leads to returns and negative post-purchase experiences.

Converting Hesitant Buyers With Visual Certainty
Vizora uses augmented reality to overlay rings and bracelets onto the shopper’s hand in real time through their smartphone camera, bringing the in-store try-on experience directly to the online product page. Buyers see exactly how a piece looks when worn rather than estimating from photographs alone.

Anniversary Ring and Accessories Pages
Keyideas designs catalog pages for every jewelry category: engagement ring pages with diamond shape, metal, and carat filtering; wedding band pages navigable by style, width, and finish; and fine jewelry, anniversary ring, and accessories pages that balance emotional product presentation with the practical attribute filtering that helps buyers reach the right item efficiently. Well-structured catalog pages reduce bounce rates and improve conversion from first visit to product inquiry or purchase across all collections.
