In short
A size chart is not enough.
The WeeFizz plugin adds “Find my size” to WooCommerce variable products. The shopper enters their gender, height, weight and age, chooses their body shape from images, and sees their size calculated in your size chart.
| 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 themselves 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 |
Key point: keep your chart. WeeFizz reads it for the shopper, who no longer has to choose between two sizes alone.

Variable products
From size to basket.
The recommended size is linked to the right variation. Add to basket goes through WooCommerce.
Tip: put the size attribute first, and name your sizes as in your size chart (S, M, L or 38, 40, 42). The recommendation is then linked to the right variation without ambiguity.
Added without reloading
The variation goes into the WooCommerce cart and the mini-cart updates.
Falls back on your theme
If the direct add does not go through, the widget selects the size and uses your button.
Size remembered
On another product linked to the same chart, with no new input. Duration from 1 to 365 days, or switched off.

FAQ
Frequently asked questions.
What is a WooCommerce size recommendation plugin, compared with a size chart plugin?
It is a plugin that tells the shopper which size to order for a given product, instead of leaving them to read a table. With the WeeFizz plugin, the shopper answers a few questions, with no photo, sees their size calculated in your size chart and adds it to basket in the right variation.
A size chart plugin displays a table; the WeeFizz plugin calculates the size in that same chart, integrated as it is and calibrated. You can keep your table.
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 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.
