Shopify shows variants in the order they were created, so sizes appear jumbled and sold-out options clutter the top of the list. VarSort keeps every product's variants in the order you choose. Build an automation: pick products with flexible conditions, set the order — size sequence (XS to XL), price, inventory, newest, or best selling — and push sold-out variants to the bottom. It also fixes the storefront size dropdown, previews changes before saving, and runs on a schedule or on demand.

• Put sizes in the right order with XS to XL presets or your own custom sequence
• Push sold-out variants to the bottom so in-stock options always show first
• Sort variants by price, inventory, newest, or best selling
• Fixes the storefront size dropdown, not just the variant list in the admin
• Preview every change before it is applied, then run on a schedule or on demand
