In short
Chart or recommendation: what is the difference?
The WeeFizz module adds “Find my size” to PrestaShop product pages. The shopper answers a few questions: their size is calculated in your size chart, then selected in your combinations.
| 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 | Opens, recommendations, add-to-baskets |
Key point: few shoppers know their chest or hip measurement. The module starts from what they already know and reads your size chart for them.
On the product page
Where does the button appear?
Next to your combinations, on every product linked to a size chart.
Three positions to choose from
Above the sizes, above the add-to-cart button, or just below it.
In your store's style
Label, colours, corners, button or link, with or without an icon. No code.
Only where it helps
Accessories and products without sizes stay unchanged.
Combinations
Your combinations, respected.
The accepted size is selected in your theme. Your add-to-cart button does the rest.
- The usual PrestaShop cart. Your checkout, your carriers, your payments.
- Drop-down list or buttons. The size is found by its label.
- Colour and size. Only the size is selected, the colour stays the shopper's choice.
- Letters or numbers. XS to 5XL, 36 to 62, T0, T1, T2: your sizes as you sell them.
Good habit: give the sizes in your chart the same names as your combinations. If the chart says “M” and the product page “T2”, the recommendation cannot be linked.
The customer journey
Three steps, one size.
- 1
Their details
Gender, height, weight and age, sent over an encrypted connection.

Their size, in your chart
14 body measurements estimated, compared with the product's chart, then remembered during the visit.

FAQ
Frequently asked questions.
What is a PrestaShop size recommendation module?
It is a module that tells each shopper which size to order for a given product, instead of showing them a table of centimetres.
With the WeeFizz module, the shopper answers a few questions, with no photo, and sees their size calculated in your size chart, then selected in your combinations. It does not replace your size chart: it builds on it, integrated as it is and calibrated by WeeFizz.
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 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.
