The Size Chart is a component used to display a product size table to help customers choose the correct size before purchasing. This reduces the rate of returns/exchanges due to incorrect size selection, helps customers shop more easily, and increases trust and user experience.

Why you need to create different Size Charts

Velmora aims to support sales across various fashion product types, each potentially having different sizing. Therefore, we need to create separate size charts for each product category.

To create a size chart for a product category (or for general use if your store has products with similar sizing), go to Shopify Admin -> Settings -> Metafields and metaobjects -> Then, under Metafield definitions -> select Products -> choose Add definition in the top right corner.

Next, in the Name field, enter Size Guide, in the Type section, select Page, and click Save to complete the setup.
Once set up, it will look like the image below.

Back in your Shopify Admin, select Online Store -> Pages -> select Add page to create a new page.
Based on your categories or how you set up each product category or a specific product, name the Title as you wish for easiest use. For example, if I use a common size for women's products, I will name the Title Women Size Guide.
In the Content section, you can set up the size chart content. Typically, simple tables are used, but you can also use images, videos, or other formats.
This is the final image after adding content.

Once the size chart is fully set up, when creating a new product or editing an existing one, in the product editing/creation interface, scroll down to the Metafields Size Guide section. Select the page you just created in the Online Store.

If the Size Guide button does not appear on the product page as shown in the image below

You need to select the Size Guide page in the metafields section on the product edit page
