Does Wix Stores have a built-in size chart?

Not as a dedicated feature. Wix Stores lets you add info sections to a product, and you can put sizing in one of them as text. For a real table, a pop-up or a cm/in switch you need an app or a custom element.

Should a size chart show body or garment measurements?

Either works, as long as you say which. Body measurements are easier for shoppers to compare with themselves. Garment measurements are more precise for fitted items. Put one line above the chart, for example "Measurements are body sizes in cm".

Can one size chart cover many products?

Yes. With info sections you can reuse the same text, but you still attach it product by product. Zutomatic Size Charts lets you write one shared chart and assign it to a collection, a product type or a keyword, so every matching product shows it.

Should I use an image for my size chart?

Only as a last resort. Text inside an image can't be read by screen readers or search engines, and it often becomes too small on phones. A text table or a size guide pop-up works better for shoppers and for SEO.

Where should the size chart go on the product page?

As close to the size picker as possible. Shoppers look for it at the moment they choose a size, so a "Size guide" link or button right under the price or next to the size options works best.

How to Add a Size Chart to Wix Product Pages (Step by Step)

How to add a size chart to Wix product pages: a product page with a Size guide button and the size chart pop-up

"Will it fit?" is the question that stops more clothing sales than price. When shoppers can't answer it, they leave, ask you by email, or buy two sizes and return one. A clear size chart next to the size picker answers it at the moment they decide.

Wix Stores doesn't include a dedicated size chart feature, but there are three practical ways to add one. Pick the one that fits the size of your catalog.

Method 1: Add sizing to a product info section

Info sections are the collapsible blocks under the product description, such as "Product info" or "Return policy". You can add one for sizing. It's free and needs no app.

In your Wix dashboard, go to Catalog, then Store Products, and open the product.
Find the Info sections area and add a new section.
Name it Size guide.
Write one line per size, for example: M: chest 96 to 100 cm, length 72 cm. Start with a line that says what you measured, body or garment.
Save the product, then repeat for every product that needs it. Products with the same sizing can reuse the same text.

Example of a Size guide info section on a product page: sizing written as plain text lines under the Add to Cart button — What an info-section size guide looks like: plain text, below the buy button.

Good for: a handful of products with simple sizing. The catch: it's plain text, it sits below the description where many shoppers never scroll, and with 100 products you'll maintain 100 copies. Change one measurement and you have to edit them all.

Method 2: Upload a size chart image

If your supplier gives you a designed size chart, you can add it as the last image in the product gallery or place it in the description.

It's quick, but it has real drawbacks:

Hard to read on phones. A chart that looks fine on a laptop often shrinks to unreadable text on mobile, where most shoppers browse.
Invisible to screen readers and search engines. The numbers inside an image aren't text. Add alt text that lists the key measurements if you go this way.
Easy to miss. Shoppers don't expect sizing as the seventh gallery photo.

Two phones compared: a size chart image is too small to read on mobile, while a text size guide pop-up stays readable with a cm/in switch — On a phone, an image chart shrinks to unreadable text. A text pop-up stays readable.

Method 3: A Size guide pop-up with Zutomatic Size Charts

This is the approach the big fashion stores use: a Size guide button right under the price that opens the chart in a pop-up. Zutomatic Size Charts adds that button to your Wix product page and writes the chart for you.

Install Zutomatic Size Charts from the Wix App Market. The free plan covers 3 products.
Open the app and click Sync products. Your products, sizes and collections come in.
Open a product and click Generate. The app uses the product's own size options as rows, so a shirt sold in S, M, L and XL gets exactly those four rows. It writes measurements for that product type, a short fit note and one tip per measurement.
Check the numbers against your supplier's sheet and edit any cell. You can also paste a table straight from Excel or Google Sheets.
Click Publish, then Add to product page on the Overview. Publish your site once.

The Zutomatic Size Charts editor: unit, category, an editable table of sizes and measurements, and a storefront preview — Every cell is editable, with a live storefront preview on the right.

Many similar products? Create a shared chart instead of one per product. Give it a rule, such as the collection "T-shirts" or titles containing "hoodie", and every matching product shows it. Fix a value once and it's fixed everywhere. A product can still have its own chart when it needs different measurements.

A shared size chart named Tops with keyword rules for shirt and sweater, showing how many products it covers — A shared chart with keyword rules. The coverage count updates as you change the rules.

On the Pro plan, shoppers also get a Find my size box inside the pop-up: they type the measurements they know and pick slim, regular or relaxed, and it recommends a size from that product's chart.

The Find my size box: chest and length entered, fit preference regular, recommendation: between Medium and Large — Find my size reads the product's own chart. Nothing about the shopper is stored.

AI-written measurements are a starting point based on the product type and description. Always compare them with your supplier's measurements before publishing.

What makes a good size chart

Whichever method you use, these five details decide whether shoppers trust the chart.

Say what you measured

"Chest 96 cm" means something different for a body and for a flat-laid garment. One line above the table removes the doubt.

Only the measurements that matter

Tops need chest and length, maybe sleeve. Trousers need waist, hips and inseam. Shoes need foot length. Extra columns make the chart harder to read, especially on phones.

Explain how to measure

Many shoppers don't know where their natural waist is or how to measure an inseam. One short sentence per measurement prevents wrong orders.

Add an honest fit note

"Runs small, size up if you're between sizes" is the line shoppers look for. If a product fits differently from the rest of your range, say so.

Offer both units

If you sell internationally, show centimetres and inches, or let shoppers switch. Converting in their head is one more reason to leave.

Which method should you choose?

	Info section	Image	Size guide pop-up
Cost	Free	Free	Free for 3 products
Next to the size picker	No	No	Yes
Readable on phones	Yes	Often not	Yes
cm and inches	Type both	Type both	Switch
One chart for many products	Copy by hand	Upload each	Shared charts
Setup per product	A few minutes	A minute	Seconds, or none with a shared chart

For five products or fewer with simple sizing, an info section is enough. For a growing clothing, footwear or accessories store, a Size guide pop-up placed next to the size picker gives shoppers the answer where they need it, and shared charts keep it manageable as your catalog grows.
