WooCommerce size recommendation, with no photo and no tape measure.
“M or L?”: the WeeFizz plugin answers instead of your size chart. On your variable products, the shopper opens “Find my size”, answers a few questions, sees the size calculated in your chart, then adds it to basket.

Size chart or recommendation
WooCommerce size chart plugin: why a table is not enough.
WooCommerce size recommendation is a plugin that tells the shopper which size to order for a given product, instead of leaving them to read a table.
Size chart plugins for WooCommerce display your chart in a tab, a pop-up or a shortcode. The shopper then needs to know their measurements to the centimetre and choose between two sizes on their own. They hesitate, order both, or leave the page.
The WeeFizz plugin keeps your chart as the reference and does the reading for them. Three ways of handling size on a WordPress store:
| No tool | Size chart plugin | WeeFizz plugin | |
|---|---|---|---|
| The shopper sees | A list of sizes | A table in centimetres | Their recommended size |
| They have to | Guess | Measure and compare | Answer a few questions |
| Your size chart | Missing | Displayed | Integrated as it is and calibrated |
| Add to basket | Manual | Manual | In the recommended size |
| Analytics | None | None | Usage, recommendations, baskets |
Inside WordPress
What the plugin adds to your WordPress.
A WeeFizz menu
Your full WeeFizz space opens inside the WordPress admin, and the Settings page holds your keys.
Synchronised catalogue
Your published products and their thumbnails appear in the WeeFizz space, with a button to synchronise again when you add products.
Settings without code
Label, colours, rounded corners, button or link, position: everything is changed from the Widget tab and applies on the next page load.
On the product page
Where does “Find my size” appear on a WooCommerce product page?
In the purchase form, close to your variations and the “Add to cart” button. You choose the exact position from your WeeFizz space.
- Above the sizes. The shopper sees the answer before even opening the selector.
- Above the add-to-cart button. Just before the decision.
- Below the add-to-cart button. More discreet, for product pages that are already busy.
The button appears on product pages whose product is linked to a size chart. It is placed using standard WooCommerce elements: a theme that keeps them needs no adaptation.
Variable products
Size variations: from recommendation to basket.
The plugin passes each variable product's variations to the widget. The recommended size is linked to the right variation, and the add to basket goes through WooCommerce.
Added without reloading
The variation is added to the WooCommerce cart and the mini-cart updates, without reloading the page.
Fallback to your theme
If the direct add does not go through, the widget selects the size in your variation list and uses your add-to-cart button.
Size remembered
The shopper's profile is remembered: on another product linked to the same size chart, their size appears without entering anything again. The duration can be set from 1 to 365 days, or switched off.
Tip for products sold in several colours and sizes: put the size attribute first, and give your sizes the same names as in your size chart (S, M, L or 38, 40, 42). The recommendation is then linked to the right variation without ambiguity.
For the shopper
A journey with no photo, in three screens.
- 1
Who is this item for?
The shopper gives the gender, then their height, weight and age.
- 2
Which body shape?
They choose, from images, the shape of their upper body, stomach and hips.
- 3
Their size
The engine estimates 14 measurements and compares them with the product's size chart. The size appears alongside the neighbouring sizes.
No camera, no biometric data. The calculation is explained on our expertise page: the WeeFizz measurement engine.
Your size charts
Your size chart, integrated as it is and calibrated.
Each size chart is integrated as it is, then calibrated by WeeFizz: the size is calculated in your brand's chart, never in a generic one. You import your charts, or start from one of 8 ready-made templates, then adjust.
In the Size charts tab, you link each WooCommerce product to its chart: T-shirts, trousers, jackets. The button only appears on linked products.

Frequently asked questions
Size recommendation on WooCommerce: your questions.
Which versions of WordPress and WooCommerce are required?
The plugin requires at least WordPress 5.6, WooCommerce 5.0 and PHP 7.2. Your WordPress admin must be served over HTTPS for the WeeFizz space to open correctly.
Does the plugin replace my size chart plugin?
It goes further. A size chart plugin displays a table; the WeeFizz plugin calculates the shopper's size in that same chart, integrated as it is and calibrated by WeeFizz. You can keep your table if you wish.
Does the button work with my WordPress theme?
Yes, as long as your theme displays the standard WooCommerce product page: add-to-cart form, “Add to cart” button and variation selectors. Check the display during the trial, or book a 30-minute call to see it on your products.
I use a caching plugin: what should I do?
Clear your page cache and your CDN after installation and after each plugin update, so that your product pages load the button.
Does the plugin slow down my store?
No. The script is light and loads after your page. The calculation runs on WeeFizz servers, not on your WordPress hosting.
Do my customers need to send a photo?
No. They enter their gender, height, weight and age, then choose their body shape from images. Their answers travel over an encrypted connection and are hosted in the European Union.
What happens at the end of the 14-day trial?
You carry on with the plan that suits you, or you stop. The trial has no commitment and the subscription can be cancelled at any time from your WeeFizz space.
