How to show size guides and care instructions on Shopify product pages
Make fit and care information easy to find without interrupting the product decision or turning every page into a wall of text.
Fit and care information answers a purchase question, not an afterthought. If a shopper cannot find it when they choose a size or compare a product, they may delay the order—or make a choice that leads to an avoidable return.
The goal is to make essential detail easy to find without letting supporting information overwhelm the product title, imagery, and buying controls.
Put the size guide beside the choice
A size guide should be available near the variant selector, with a short label that tells shoppers what they will find. If sizing differs by product, connect the guide to the relevant product rather than relying on a generic page. A customer should not have to open a new tab, hunt down a PDF, then try to remember which size they were considering.
Include the information needed to make the choice: garment or product measurements, units, fit notes, and a clear indication of whether the numbers refer to the item or the body. A model's size can help, but it should not be the only sizing instruction.
Make care details scannable
Care instructions belong with the product information a shopper may revisit before buying. Use short, practical language such as wash temperature, drying guidance, cleaning restrictions, or material-specific cautions. Icons can help scanability when they are explained in text and do not replace it.
Use predictable information blocks
Shipping, returns, size, materials, and care can live in a consistent group of collapsible sections or product information blocks. Consistency teaches a returning customer where to look without forcing every detail into the primary product description.
If information changes the likelihood that a shopper selects the right variant, make it visible before add to cart. If it supports ownership after purchase, it can sit one level lower in the product information.
Review the mobile version first
Long tables, dense measurement charts, and image-only care symbols often fail on a narrow screen. Test a real product page on a phone: can a shopper find the size guide, understand it, and return to the variant selector without losing their place? That is the experience the information needs to support.
