Wrong sizes are the top reason for clothing returns. A **size chart** shows customers the measurements behind each size (bust, waist, hips, length, foot length) in their own size system, before they buy. You set charts up once per category and every product picks them up.

> **How to turn it on**
> 1. **Plan:** Included in every plan.
> 2. **Switch:** No switch. Open Products › Size charts.
> 3. **Permission:** View size charts; Add, edit and delete size charts (User Management › Roles).
> - **Mobile app:** Shown on your online store, widgets, the SmartPOS Shopper app and the web POS.

## Before you start

Your categories exist ([step 1](https://docs.smartposhub.com/business-types/boutique/step-1-store-modules-and-categories/)) and size names on your products match the sizes in the chart ([step 2](https://docs.smartposhub.com/business-types/boutique/step-2-sizes-colors-and-variant-photos/)).

## Set up your charts

1. Open **Products › Size charts** and click **Import prebuilt**. Tick the charts you need, for example Women's Dresses, Women's Tops & Blouses, Women's Skirts, Women's Trousers & Pants and Abaya Sizes, then import.
2. Click **Markets**. The size systems for your country are ticked (for example INT, EU, UK, US). Tick **Show all size systems** if you sell abroad.
3. Click **Edit** on each chart and set **Applies to**: pick the categories (and brands) it covers. Save. The list shows how many **Products** each chart now covers.
4. Click **View chart** to check what customers will see.

*Each chart shows its size systems, which categories it applies to and how many products use it.*

## Choose a chart on one product

On **Add / Edit product**, the **Size chart** field sits under the categories. **Automatic (from category or brand)** is the default, and the hint tells you which chart will show. Pick **No size chart** for items such as bags, or a chart name to override.

*Automatic uses the chart of the product's category or brand.*

## Tips

- **Write a fit note**: "Relaxed fit. If you are between sizes, take the smaller size." It answers the most common question.
- **Use Duplicate** to make a petite or kids version quickly.
- **Bags, scarves and fragrance** don't need a chart: set their categories to no chart, or leave them out of **Applies to**.

## Frequently asked questions

As a Size guide on the product page of your online store, in shop widgets and in the SmartPOS Shopper app. Cashiers can open it in the POS from the cart line.

### One brand runs small. What do I do?

Duplicate the chart, adjust the measurements and attach the copy to that brand and category. The most specific chart wins.
