Title: Perfect Ring Fit Author: Riya Patel Published: October 20, 2026 Last modified: October 20, 2026 --- Search plugins ![](https://s.w.org/plugins/geopattern-icon/perfect-ring-fit.svg) # Perfect Ring Fit By [Riya Patel](https://profiles.wordpress.org/riyapatelwork20/) [Download](https://downloads.wordpress.org/plugin/perfect-ring-fit.1.0.1.zip) * [Details](https://wordpress.org/plugins/perfect-ring-fit/#description) * [Reviews](https://wordpress.org/plugins/perfect-ring-fit/#reviews) * [Installation](https://wordpress.org/plugins/perfect-ring-fit/#installation) * [Development](https://wordpress.org/plugins/perfect-ring-fit/#developers) [Support](https://wordpress.org/support/plugin/perfect-ring-fit/) ## Description Perfect Ring Fit helps shoppers estimate a ring size by matching a circle to the inside edge of a ring. Shoppers first calibrate the on-screen scale against a standard bank/credit card (85.6 mm wide) or a 50 mm ruler reference. The guide then scales the circle using that calibration. Features: * Card calibration using the standard 85.6 mm card width. * Physical ruler calibration using a 50 mm reference. * India sizes 4–16 with approximate US/ EU equivalents and inner diameters. * Responsive modal interface. * Optional automatic button placement on WooCommerce products in selected product categories. * Shortcode support for pages, posts, and page builders. * Customizable button label and primary colour. * No external service calls, tracking, or user data collection. Measurement accuracy depends on the shopper correctly matching the on-screen reference to a physical card or ruler. Ring size conversion charts can vary by jeweller and region; results are estimates and should be checked against the store’s own sizing chart before purchase. ### Privacy This plugin does not collect, store, or transmit personal data. ## Installation 1. Upload the `perfect-ring-fit` folder to `/wp-content/plugins/`, or upload the ZIP through Plugins > Add New > Upload Plugin. 2. Activate the plugin. 3. Open Settings > Ring Size Guide to configure the button. 4. To place the guide on any page, add the shortcode `[ring_size_guide]`. 5. To show it automatically on product pages, enable Automatic product button and configure the eligible product category slugs. WooCommerce is required to activate this plugin. The guide can be placed on pages with the [ring_size_guide] shortcode and can optionally be inserted on eligible WooCommerce product pages. ## FAQ ### How do I display the guide on a page? Add `[ring_size_guide]` to the page or use your page builder’s shortcode widget. ### How do I show it automatically on ring products? Go to Settings > Ring Size Guide, enable Automatic product button, and set your ring category slugs. The defaults are `ring,rings`. Parent categories are supported. Category matching is exact to avoid matching terms such as `earring`. ### Is the measurement guaranteed to be exact? No. The guide relies on the shopper aligning a physical card or ruler with the on- screen reference. Display hardware, browser zoom, and user alignment can affect results. The conversions are estimates and should be validated against your own jewellery sizing chart. ### Does this change product prices or cart calculations? No. The plugin only displays a measurement guide. It does not modify prices, variations, cart data, or checkout calculations. ### Does it collect or send shopper data? No. The plugin does not make external requests or collect measurement data. ## Reviews ![](https://secure.gravatar.com/avatar/430199cfc4ed22580d3026a850e2aac16da199f0e4f46f5f04358d6aecbd4f74? s=60&d=retro&r=g) ### 󠀁[A Useful Ring Size Guide for WooCommerce](https://wordpress.org/support/topic/a-useful-ring-size-guide-for-woocommerce/)󠁿 [customizetheme](https://profiles.wordpress.org/customizetheme/) October 20, 2026 I tested Perfect Ring Fit on my WooCommerce store. The ring-size guide helps shoppers estimate their ring size using an on-screen calibration method. The interface is straightforward, and the sizing guide is a useful addition to a jewelry product page. It would be helpful to see continued improvements and compatibility updates.
