If you only offer one size for each product you may prefer to use a metafield to set the artwork size. Follow the steps below to create the "artwork.size" metafield for your store and set it for a product. ### 1. Create the metafield definition On a product page in the Shopify admin, scroll down to the "Metafields" section and click "View all". Empty metafields section on product page You should now see the product metafields for your store. You may already have some. Click "Add definition": Add a custom field to your products You should see the "Add product metafield definition" screen. Type in the name of the metafield, e.g. "Artwork Size", then click where it says "custom.artwork\_size". Add product metafield definition Delete the "custom.artwork\_size" and type in "artwork.size". This must match exactly: Set namespace and key to 'artwork.size' exactly Set the type to "Single line text": Set type to single-line text Now click "Save" at the top of the page to save this metafield definition. ### 2. Set artwork size for each product Return to a product page in Shopify admin, scroll down to the Metafields section and you should be able to type in your artwork size like below: Set artwork size for a product Click 'Save' and Frame Up will now automatically detect this as the artwork size.
