How to Add a Size Chart in PrestaShop

You can add a size chart in PrestaShop in three ways: put a table in the product description, link a CMS page to your products, or install a size guide module. The product description is the fastest, and a module is easier to manage across many products.

This guide is for store owners and developers on PrestaShop. If you also run other platforms, the guide to virtual try-on for WooCommerce shows how a similar setup works there. Menu names can differ between PrestaShop versions, so check them against the PrestaShop documentation.

What should a size chart contain?

Before you add anything, decide what the chart must say. A useful chart has:

• Body measurements, not just garment widths, with units labeled.
• Your own size labels, such as S, M and L or numbers.
• One chart per garment type, because tops, trousers and dresses fit differently.
• A fit note, such as "relaxed fit, size down for a closer fit".

Label the chart as your own. If you copy a supplier chart, say which brand it belongs to.

How do you add a size chart to the product description?

This option needs no extra tools. It suits small catalogs.

1. In the back office, open the product from Catalog → Products.
2. In the description field, add a table or an image of the chart.
3. Save and view the product page.
4. Check the table on a phone, where wide tables can overflow.

The downside is repetition. If you change a size, you must edit every product that uses the chart. Keep the chart in one place, such as a spreadsheet, and copy from it.

How do you add a size chart with a CMS page?

A CMS page holds the chart once, and products link to it. You can usually find pages under Design. Check where this sits in your version.

1. Create a new page and name it something clear, such as "Women's tops size guide".
2. Add your table and fit notes.
3. Publish the page and copy its address.
4. Add a link, such as "Size guide", to each relevant product description.

When a measurement changes, you edit one page. The weakness is that the shopper leaves the product page unless you open the link in a pop-up, which depends on your theme.

Should you use a size guide module?

Modules can show a chart in a tab or pop-up and apply it to groups of products. The details vary by module and PrestaShop version, so read each module's listing and its compatibility notes before buying, and test it on a staging copy of your store.

Ask these questions about any module:

• Does it support one chart per product category?
• Does it work on mobile?
• Is it compatible with your PrestaShop version and theme?
• Is the author still updating it?

A chart still only shows numbers. The shopper must measure themselves and compare. That gap is why some stores add a size recommendation. Our comparison of size chart apps and recommendation apps explains the difference, using Shopify examples.

How do you add size advice on top of the chart?

ZeDaq.ai has no PrestaShop module. It does offer a script-tag widget for custom sites, and a REST API. If you can edit your theme's product template, you can paste this tag into it:

<script src="https://www.zedaq.ai/widget/zedaq.js" data-key="…" defer>

Lock the key to your store's domain in Dashboard → API keys. The widget adds "Try it on" and "Find my size". Setup details are in the widget documentation.

For sizing, enter your own chart in Dashboard → Size charts, one chart per garment type: tops, outerwear, dresses and bottoms. The scan, which uses one photo plus height, then recommends your own labels. If you build your own flow, the API reference is at /en/docs/api.

Test on a copy of your theme first, and check the result on a phone.

How do you check that the chart works?

Run this checklist before you go live:

• The chart is readable on a small screen.
• Units are labeled and match your market.
• Each product points to the right garment chart.
• The link or tab is easy to find near the size selector.
• The chart matches the real garments in a fitting test.

If you also sell elsewhere, the steps differ by platform. See how to add a size chart in BigCommerce or how to add a size chart in Webflow.

FAQs

Can I add a size chart to every product at once?

Not with a plain description table. A CMS page link or a module lets you reuse one chart across many products.

Should I use inches or centimeters?

Use the units your shoppers know, and label them. If you sell in several countries, show both.

Do I need a developer to add a size chart?

Not for a description table or a CMS page. A developer helps with a theme tab, a pop-up or the widget tag.

Does ZeDaq.ai have a PrestaShop module?

No. You can use its script-tag widget on a custom site by pasting the tag into your product template, or call the REST API.
