In fashion, “wrong size” is one of the most common reasons for returns. Every return costs shipping, handling and sometimes the customer. A clear size guide right next to the Add to cart button is one of the cheapest fixes.
What makes a size guide useful
- Visible where the decision happens: a “Size guide” link next to the size selector or the Add to cart button.
- Readable on phones: a scrollable table with the first column fixed.
- Both units: a cm / inches switch for international customers.
- How to measure: a short text and a diagram for chest, waist, hips, inseam.
- Specific per category: shoes, tops and trousers need different charts.
Setting it up in WooCommerce
- Install Sizely and create a size chart. The editor works like a spreadsheet, and you can paste a table from Excel or Google Sheets.
- Choose which columns convert between cm and inches.
- Add your “How to measure” text and image.
- Assign the chart to product categories: every product in the category gets it automatically, sub-categories included.
- Pick where the link appears on the product page.
Open the “Size guide” on the live demo to try it.
Write a few fit notes
Beyond the chart, one sentence like “runs small, take one size up” on a product page can prevent many returns. Your customer reviews often tell you which products need it.
More WooCommerce quick wins
Pair the size guide with a sticky Add to cart bar on mobile and back in stock alerts for sizes that sell out. Read the full list in our WooCommerce conversion tips.
Frequently asked questions
Can I use one size chart for many products?
Yes. Assign the chart to a product category and every product in it, including sub-categories, shows the guide.
Can I import my existing size chart?
You can paste a table straight from Excel or Google Sheets into the editor.
Does it work on mobile?
Yes. The pop-up is accessible and the table scrolls with a fixed first column on phones.
