PrestaShop size recommendation: “M or L?” solved for your store.
The WeeFizz module adds a “Find my size” button to your PrestaShop product pages. The shopper answers a few questions, with no photo, and sees their size calculated in your own size chart before adding to basket.

Definition
PrestaShop size guide module or size recommendation: what is the difference?
A size guide module displays a table of centimetres. A size recommendation module gives an answer: the size to order, for this shopper and this product.
Most “size chart” modules for PrestaShop open a window showing your chart. That helps, but your customer has to know their chest, waist and hip measurements, then compare on their own. Few people know these figures: they hesitate, order two sizes or give up.
The WeeFizz module starts from what the shopper already knows. The WeeFizz engine works out 14 measurements, then finds the matching size in each product's size chart. The chart remains your reference; what changes is who reads it.
| Size chart module | WeeFizz module | |
|---|---|---|
| What the shopper sees | A table of measurements | Their recommended size |
| What they have to do | Measure themselves, then compare | Answer a few questions |
| Basis of the calculation | No calculation | Your size chart, product by product |
| Photo or tape measure | Tape measure advised | Neither |
| What you learn | Nothing | Openings, recommendations, add-to-baskets |
On the product page
Where does the “Find my size” button appear on PrestaShop?
On every product page linked to a size chart, next to your combinations and your “Add to cart” button.
Three positions to choose from
From the Widget tab of your WeeFizz space: above the sizes, above the add-to-cart button, or just below it.
In your store's style
Label, colours, rounded corners, button or simple link, with or without an icon: the widget is set up without touching any code.
Only where it helps
The button only appears on products linked to a size chart. Your accessories and unsized products stay as they are.
Combinations
Your PrestaShop size combinations, taken into account.
The module reads each product's combinations. When the shopper accepts the recommended size, it is selected in your theme and your add-to-cart button does the rest.
- Your usual PrestaShop cart. No parallel basket: the order goes through your checkout, carriers and payment methods.
- Drop-down list or buttons. The size is found by its label, whatever selector your theme uses.
- Colour and size. On a product sold in several colours and sizes, only the size is selected: the colour stays the one the shopper chose.
- Letters or numbers. XS to 5XL, 36 to 62, T0, T1, T2: the module follows your sizes as you sell them.
Good practice: the sizes in your size chart should carry the same names as your combinations. If the chart says “M” and the product page says “T2”, the recommendation cannot be linked to the right combination.
The shopper journey
How the shopper finds their size, no photo needed.
Three steps, a few seconds and no biometric data. Shoppers answer with what they already know.
- 1
Their details
Gender, height, weight and age, sent over an encrypted connection.
- 2
Their body shape, in images
Upper body, stomach, hips: they pick the image that looks like them.
- 3
Their size, in your size chart
The engine estimates 14 measurements and compares them with the product's size chart. The size appears, ready to add to basket.
The size is then remembered during the visit: on the next product linked to the same size chart, the shopper sees it without answering again. To understand the calculation in detail, see how the WeeFizz recommendation engine works. If you also want to show the garment worn on the shopper's own photo, that is a separate service: WeeFizz virtual try-on, where the size is still calculated with no photo.
Your size charts
Your size chart, integrated as it is and calibrated.
Your own charts
Each size chart is integrated as it is, then calibrated by WeeFizz. The size is always calculated in your brand's chart, never in a generic one.
Imported or ready-made
You import your charts, or start from one of 8 ready-made templates, then adjust.
One chart per family
Tops, trousers, jackets: each product is linked to the chart that fits it, with the thumbnail from your PrestaShop catalogue to find your way.

Your analytics
Analytics, inside your PrestaShop back office.
The WeeFizz space is displayed directly in PrestaShop, with its Overview, Analytics, History, Size charts, Widget and Administration tabs. During the trial, you see on your own product pages:
- Widget usage. Visits, openings and usage rate, product by product.
- Recommendations. The recommended sizes and the history, exportable as CSV.
- Add-to-baskets. How many shoppers add to basket after their recommendation.
- Products that cause hesitation. With the Studio plan, recommended sizes compared with the sizes actually chosen.
It is the simplest way to judge the effect on your size-related returns with your own figures.

Frequently asked questions
PrestaShop size recommendation module: your questions.
Which PrestaShop versions does the module support?
The WeeFizz module is compatible with PrestaShop 1.7 and later versions. It installs like any other module, from the module manager in your back office.
Does the module replace my size chart?
No, it builds on it. Your size chart is integrated as it is and calibrated by WeeFizz. Shoppers no longer have to decode it on their own: they answer a few questions and see their size straight away.
Does the button work with my PrestaShop theme?
The module uses the standard PrestaShop product page positions and your theme's combination selector, whether it is a drop-down list or buttons. If your theme is heavily customised, check the display during the trial, or book a 30-minute call to see it on your products.
Do I need a developer to install the module?
No. You create your account, upload the module, paste your keys into the configuration and link your products to their size chart. The button then appears on those product pages.
Do my customers need to send a photo or measure themselves?
No. They enter their gender, height, weight and age, then choose their body shape from images. No photo, no tape measure.
I run several stores on the same PrestaShop installation: what should I do?
Each WeeFizz subscription covers one store. For several stores, you need one subscription per store. Write to us to discuss it.
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.
