Size charts shoppers actually understand

Match my store

It looks like your store. Automatically.

Sizefolk reads your theme's colours, fonts and button shape, so the size guide feels like part of your store, not a plugin. Here's the same size guide in three different stores, with no settings changed.

  • Your colours. Buttons, toggles and the selected size use your brand colour.

  • Your fonts. Headings use your theme's heading font.

  • Your shapes. Square, rounded or pill: the guide copies your Add to cart button.

How to measure

Chest: measure around the fullest part, keeping the tape level. Waist: around your natural waistline. Length: from the highest point of the shoulder down to the hem.

How it works

  1. Pick a template

    Tops, jeans, dresses, bras, kids, shoes, hats, rings, gloves, or start blank. Import your existing charts from CSV.

  2. Choose where it shows

    Products, collections, tags, product types or vendors, with exceptions.

  3. Switch it on

    One click adds a Size guide link under the size picker, or place it anywhere in your theme.

Features

See where to measure

Every chart gets a drawing (tops, trousers, dresses, bras, shoes, hats, gloves, rings). Shoppers tap a size and its measurements appear on the garment, in cm or inches.

Find my size

Shoppers enter their measurements, or their height and weight, and get a size recommendation from your chart. It's remembered on their device, so every product shows their size.

Know which products come back for size

Sizing insights read the reasons on your Shopify returns and show which products come back too small or too large, what those returns are worth, and which chart to fix. One click adds a “Runs small” note to the chart.

Example

Ask Sidekick

Ask Shopify Sidekick “Which products don't have a size chart?” or “Which chart does this product use?” and Sizefolk answers from your store.
