How to add Size Chart to your website

Embed Size Chart on Your Website

01

Create a Size Chart widget for your website on Common Ninja

First, create a Size Chart widget on Common Ninja. On the widgets catalog, find the Size Chart and enter the Editor.

02

Save the Size Chart widget

When you're done creating the Size Chart widget, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Size Chart Embed Code

When you're ready to add the Size Chart widget to your website, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the widget embed code. In the next steps, you will paste this code into your website.

04

Paste the code to your Platform website’s HTML field.

Next, go to your Platform website editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Platform’s editor. Add it to your page, and paste the Size Chart Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Size Chart widget on your Platform website.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Size Chart widget on your Platform widget. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Platform website’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Size Chart widget to your Platform website. You can do this by putting it straight into your Platform website's HTML code.

Why Use This Widget

Use the Size Chart widget when accurate sizing affects purchase confidence and return rates. Shoppers often hesitate if measurements are unclear, especially across categories like clothing, shoes, or accessories. A structured size chart with visual guides and tabs helps visitors find the right fit quickly, reducing uncertainty before checkout. This is essential for ecommerce brands serving multiple regions or offering varied sizing standards. Clear charts lower returns and exchanges because customers choose more accurately the first time. By presenting measurements in a consistent, mobile friendly layout, you improve usability and trust. A good size chart signals that you care about customer success, makes buying feel safer, and supports higher conversion rates on product pages.
