What should a Shopify clothing size guide include?

Explain what each measurement describes, where it is taken and which unit you use. A table of unexplained numbers is not enough.
Why accurate numbers can still confuse
A customer might measure a favourite garment while your chart lists body measurements. Both sets of numbers can be correct but lead to the wrong size. Name the measurement type and show a short measuring method. For an abaya, explain the length reference and relevant fit information. Use your own approved product measurements. Put the guide beside the size choice so shoppers do not have to abandon the product to find it.
Distinguish body and garment measurements
State whether a number describes the customer’s body or the finished garment. Label the unit and explain where each measurement is taken. For abayas, length and fit information may be especially important. Have someone responsible for the actual product approve the values before publication.
Place the guide near the decision
Customers need size information while choosing a variant. Make it easy to reach without losing the product context. A clear table, a short measuring explanation and a relevant diagram can work together. Review the guide on mobile and ensure text remains readable without excessive sideways scrolling.
Keep promises precise
Avoid claims such as universal fit unless the product facts support them. Explain any made-to-order differences and the actual exchange process. Shopify’s description guidance treats specifications as useful product information; the practical challenge is making your own measurements accurate and understandable.
Explain how to take the measurement
State whether the table measures the garment or the body and use consistent units. Add a simple explanation of where to measure and any product-specific fit information you can verify. Test it with someone unfamiliar with the item; an unexplained table can still leave the main buying question unanswered.
