Meet the module
The Size Chart module for Magento 2 is a practical extension that significantly improves the shopping experience in online stores offering apparel, footwear, and other products that require size matching.
Benefits of using the module
Fewer returns – customers make more informed purchases thanks to a clear size chart.
Higher conversion rate – fewer questions about size fit = faster purchase decisions.
Intuitive experience – the size chart opens in a convenient popup without reloading the page.
Easy content editing – the size chart is pulled directly from the product attribute, e.g. tabela_rozmiarow.
Responsive design – works correctly on mobile and desktop devices.
How does the module work?
On the Magento 2 product page, the module automatically detects the attribute that defines the size variant, e.g. size, and dynamically adds a Size Chart button next to the size label. After the click, the content of the tabela_rozmiarow attribute is loaded via AJAX and displayed in a modal popup without reloading the page.
An ideal solution for stores
selling women’s, men’s, or children’s apparel
selling athletic or dress footwear
selling accessories that require sizing
selling workwear, safety, or outdoor products
Why is it worth it?
A customer who knows their measurements but does not know how a given brand interprets them often abandons the purchase. With a size chart available directly at variant selection, you build trust and reduce purchase barriers. What is more, the solution does not interfere with the template, and the chart content may also include images, e.g. dyrektywa media z parametrem url='wysiwyg/tabela/rozmiarow.png', otoczona podwójnymi nawiasami klamrowymi.
SEO and UX in one
The module improves store usability by providing content that helps customers choose the right size and may support conversion. The SEO and bounce rate topics mentioned in the existing description depend on the overall implementation; the module does not guarantee search engine rankings.

Attribute and content configuration
In Stores → Configuration → Kowal → Tabela Rozmiarow, you enable the module, select the attribute code for sizes, and choose one or more attributes with the description. size and tabela_rozmiarow are examples: you choose sources that match your own catalog structure.
The controller combines content from the selected attributes and processes Magento directives. If no data is available, it displays a message that the chart is unavailable. The interaction between the button and popup with the theme in use and the variant selection method should be verified during implementation.
Installation via Composer
Package kowal/module-tabelarozmiarow, module Kowal_TabelaRozmiarow. After configuring access to the Kowal repository, install the package, enable the module, update Magento, and clear the cache. In production, include compilation and static content deployment according to your store’s process.

2. Complete the product data Add a table, description, or measurement illustration.
3. The customer opens the chart The button next to the variants launches an AJAX popup.
Different brands, the right size chart

The content can combine a table with an illustration showing how to measure.

They are also available in the customer panel after logging in at kowal.store. Replace TWOJ_EMAIL_KLIENTA with your account email address and TWOJ_TOKEN with the token you received. Run the commands in the Magento root directory.

TourSport.pl – size chart management for multiple manufacturers
The TourSport.pl store offers a wide range of sports and outdoor products, from technical apparel and accessories to travel equipment from many different manufacturers.
Problem
Stores offering products from many brands very often face challenges related to different sizing systems. Each manufacturer uses its own fit chart, size labels, and measurement parameters.
In practice, this means that:
one size M can represent completely different measurements depending on the brand
manufacturers use different table layouts (height, chest circumference, sleeve length, etc.)
customers have difficulty choosing the right size
For TourSport, this meant the need to present many different size charts, often assigned to specific manufacturers or product categories.
Solution
Implementing the Size Chart for Magento 2 module enabled flexible size chart management across the entire store.
With the module, the store administrator can:
assign individual size charts to specific products
assign one chart to multiple products at once
create different chart sets for different manufacturers
manage them easily from the Magento admin panel
This approach keeps size information consistent throughout the store, even when the offering includes products from many brands.
Result
After implementing the module, the TourSport store gained a much clearer system for presenting size charts.
Key benefits:
customers find the right product fit information faster
the number of size-related questions is reduced
the store administrator can conveniently manage charts for the entire offering
As a result, the Size Chart for Magento 2 module became an important element improving the shopping experience in a store offering products from many manufacturers.
Slumbersac.pl – Size Chart for Children’s Sleeping Bags
The Slumbersac.pl store specializes in selling children’s sleeping bags and sleep accessories for young children. The brand’s products stand out for their high-quality materials, various thickness options (TOG), and a wide range of models matched to a child’s age and height.
Problem
For children’s sleeping bags, choosing the right size is much more complex than for standard clothing.
Parents often have questions:
which sleeping bag size is suitable for the child’s age
whether the sleeping bag length will be appropriate for the child’s height
whether the selected model will be too tight or too loose
An additional challenge is that sleeping bag fit is often based not only on the child’s age, but also on their height and the construction of the specific product model.
Without a clear size chart, customers often need to contact store support or make a purchase decision with considerable uncertainty.
Solution
The Size Chart for Magento 2 module was implemented in the Slumbersac.pl store, enabling detailed fit information for sleeping bags to be displayed directly on the product page.
The module allows for:
displaying a size chart tailored to the specifics of children’s products
easily showing fit information based on the child’s height
clearly presenting data in a table available to customers during purchase
As a result, parents can quickly check which size will be right for their child.
Result
After the module was implemented, the size chart became an important element of product pages in the Slumbersac store.
Key benefits:
customers can easily choose the correct sleeping bag size
the number of questions about product fit is reduced
customers feel more confident when making a purchase decision
For children’s products, where safety and comfort are essential, a clear size chart significantly improves the customer shopping experience.
