When Vitals Size Chart is not the right fit

  • Automatic cm and inch conversion of the chart. Vitals Size Chart shows the chart exactly as you create it, so add both units to your table or image if your shoppers need them.
  • Bulk import or export of charts. Charts are created one at a time in the app, or by duplicating an existing chart.

Why do we need a Size Chart?

Displaying a Size Chart on product pages can help you boost conversion and reduce return rates. 

According to a study by the Baymard Institute, 35.3% of online shoppers have abandoned a purchase because of a lack of size information.

With accurate size information available on the product page, customers are:

  • Less likely to purchase the wrong size, which will result in fewer returns. 
  • More likely to make a purchase as they can be confident that the product will fit them well.

Make sure the Size Chart app is active (click Activate app on the Size Chart page) to show charts on your product pages.

How to create a Size Chart

You can create multiple Size Charts and display them on specific products, collections, or all product pages.

1. Create a new size chart by clicking the Create Size Chart button.

Under General settings, enter the Title shoppers see at the top of the pop-up and an Internal name for your own list. Both are required to save the chart.

2. Visibility: Select which product pages to show the size chart. You can display it on all product pages or specific collections or products. 

By default, the size chart will be shown on all product pages. If you want to change this, in the Visibility section, click Select Products to open the selection modal and choose the products that you want. Then click Select Products.

3. Select how you want to create your size chart

  • From Image - by uploading an image size chart; 
  • Create Table - create a size chart table from scratch;

You can also display a measuring guide near the size chart for any of the options.

Create a Size chart from an image

  • Select the From Image option
  • Upload the image size chart by clicking in the Add file area. Supported file formats are .png, .webp, .jpeg, .jpg and .gif.

Create a size chart table

  • To create a table from scratch, select the option Create Table. 
  • Edit the size chart table using the table editor. You can add columns or rows by right-clicking on the table or by using the editor shortcuts. 
  • You can change the style applied globally to all size charts from the Settings tab. Global styles are only visible in the storefront and are not reflected in the table editor.
  • You can apply different styles for specific size charts, using advanced features from the table editor.

Style options from the Settings tab are applied globally to all size charts. These will only be reflected on the storefront and not in the table editor from the Create Size Chart page.

4. Choose if you want to display also a measuring guide near the size chart. Here you can give helpful tips and information for the measuring process. 

If you wish to show the guide, check the option Enable "How to measure" guide.

5. Edit the measuring guide (optional).

If you want to customize the measuring guide, you can edit the information directly in the editor. 

You can change the text and the image shown in the how-to-measure guide. If you want to change the layout, delete the content provided in the editor first.

You can upload your own images in the editor using the Upload Feature. 

You can edit the style of the text using the options provided in the editor.

6. Choose where to display the how-to-measure guide in the Size Chart modal. You can place it below or above the size chart.

7. Publish the Size chart by clicking the Publish button. Make sure the app is active. 

Now the size chart should be visible on your store’s selected product pages. Don't forget to hard refresh the page to see the Size Chart button.

How are Size Charts Prioritized

Suppose multiple Size Charts target the same products. In that case, the most specific one will have priority over a more general one (e.g., a size chart for a specific product will have priority over a size chart on a collection or all products).

Also, the most recently updated will have priority. So if you have two size charts for the same products, the most recently updated will be displayed on the product page.


How to edit the Size Chart Table Style

You can change the style of the tables created in the Table Editor.

  • Go to Settings Tab
  • Go to Table Style section
  • Choose one of the layouts available
    • Horizontal borders (this is the default option)
    • Vertical borders
    • Simple

For the Horizontal borders and Vertical borders layouts, you can choose the striped row background color and the border color. For Simple, you can change the border color.


For Border thickness, you have 3 options: Thin, Regular or Bold.

Any changes made in this section will only be visible on the storefront and will not be reflected in the size chart table editor. These changes will be applied globally to all created size charts. If you want to style a particular size chart differently, use the advanced option available in the table editor.

How to edit the style of the modal 

  1. Go to the Settings Tab in the Modal style section.
  2. Choose the background color for the modal.
  3. Choose the text color for the modal. Ensure you have enough contrast, so your users can easily read the text.

How to add the size calculator

Go to the Settings tab, open the Size calculator section and turn on Show a size calculator. It appears on size charts whose table lists body measurements: shoppers enter theirs and see the size that fits.

How to Place the Size Chart Button

The Size Chart button is placed automatically near the Add to cart button on product pages. 

You can change its placement in different ways. For more information about these procedures, you may refer here: How to Move Vitals Apps Around Your Shopify Store Pages
