Size guides your shoppers actually use
ILM Size Chart Pro for WooCommerce adds a clear size guide to your product pages: in a popup behind a button, or right on the page. You build each guide yourself from tables, tabs, pictures, videos and text, and decide which products show it. Shoppers switch between cm and inches with one click.
Sizechart Designer
Build a guide from rows and columns. Each column holds a table, tabs, a picture, a video, an iframe or text. Move things around, undo and redo, and export a design to reuse it on another chart.
- Rows and columns you arrange freely
- Tables, tabs, pictures, videos, iframes, text
- Undo, redo, export and import
Tables with a unit switch
Paste your sizes straight from Excel or Google Sheets. Add cm, inches or any other unit with its conversion value, and the shopper switches between them above the table.
- Paste from Excel or Google Sheets
- Any unit, any conversion value
- Sticky first column
13 ready-made themes
Give your tables a finished look in one click. Pick one of 13 themes, from clean and light to dark and bold, and every table in the chart takes the new look.
- Apply a theme to the tables you already have
- Light, colourful and dark looks
- Change the look at any time
Popup Button designer
Design the button, its icon, the popup window and its close button, and watch a live preview while you change them. Place the button with the plugin's own position or next to any element of your product page.
- Text, icon, colours, border and spacing
- Popup size, position on screen and animation
- Live preview before you save
Display rules
Choose where each chart appears: on selected products, categories, brands, tags or attributes. Apply Constrain to narrow a rule down. When several charts match a product, the one with the highest priority is shown.
- Products, categories, brands, tags, attributes
- Apply Constrain to narrow a rule
- Switch a chart off without deleting it
AI chart builder
Describe your sizes in words, or upload a picture of a chart, and the AI drafts a complete chart. It works with the ILM Tech AI service, or with your own key for Claude, DeepSeek, OpenAI or Gemini.
- Create a new chart in a few steps
- Upload a picture of a chart
- Free AI requests to try the builder
Find my size for shoppers
Shoppers enter their measurements, or height and weight, and get a size suggestion with a fit note for each body part. The calculation runs in the browser, so measurements stay on the shopper's device.
- A size suggestion for the shopper
- A fit note per body part
- Measurements stay on the shopper's device
