Size Chart Setup Guide

The Size Chart section (found in the default Product Page template) helps customers match their measurements to your product’s sizes (e.g., clothing bust/waist sizes). It reduces return rates by clarifying fit details upfront, and is built by adding/editing Row blocks to define measurements (e.g., Size, Bust, Waist) and their corresponding values.

Access Size Chart settings in:
Online Store → Themes → Customize → Product page → Size chart

Global Size Chart Settings

These settings control the overall title, notes, and spacing of the Size Chart section.

Heading

Note

Adds a small disclaimer/context below the chart (critical for avoiding size confusion).

Section Spacing

Adjusts padding above/below the Size Chart to fit your Product Page flow.

Theme Settings

Controls styling for the chart’s border:

Row Block Settings (Build the Chart)

The Size Chart is constructed with Row blocks — each Row represents a measurement (e.g., Size, Bust, Waist) and its values across sizes. Add new Rows with the + button in the customizer.

This is a row header

Toggle to mark a Row as the header row (defines the size labels, e.g., XS, S, M).

Row name

Names the measurement for the Row (displayed in the leftmost column of the chart).

Column values

Enter the values for each size column (comma-separated, matches the order of the header Row’s sizes).

Mismatched column values (e.g., 6 sizes but 5 values) will break the chart layout — double-check the number of commas!
