# How to sell a product in sizes & colours

> Why your product form shows one price box — and how to turn on options so you can set a price and stock for each size or colour.

If your product comes in **sizes** or **colours**, you can give each option its own price and its own stock count. The catch that confuses most sellers: by default the product form shows **one price box and one stock box** — because your store starts in *simple* mode. You switch that on once, in your catalog setup.

> **Two separate questions:** "Does each option cost a different price?" and "Do you track stock separately per option?" are independent. You can have same-price-but-separate-stock (common for clothing), or different-price-per-size, or both.

## Step 1 — Turn on per-option pricing/stock

1. Open **Settings → Catalog & fields** and find the **Pricing & stock** card.
2. Set **Pricing** to **Different price per option** *only if* a Large should cost more than a Small. If every size is the same price, leave it on **One price per product**.
3. Set **Stock tracking** to **Stock per option** if you want a separate count for each size/colour. (Other choices: **One stock count per product**, or **Don't track stock**.)
4. Save. This changes what the Add Product form shows for *every* product — so it's worth doing before you add lots of items.

## Step 2 — Add the options on your product

1. Open the product (or **Products → Add product**) and find the **Options** section.
2. Add an option type — e.g. **Size** — and its values separated by commas: `S, M, L, XL`.
3. Add another if you need it — e.g. **Colour**: `Red, Blue, Black`.
4. Click **auto-generate variants** to create every combination (S/Red, S/Blue, M/Red…) in one tap.

## Step 3 — Fill in the variant grid

A grid of variants appears. Depending on the models you chose in Step 1, each row lets you set a **price** and/or a **stock count** for that exact combination. Remove any combination you don't actually sell.

> **Same options on most products?:** Set your common options once under **Settings → Catalog & fields → Default options (like Size or Colour)** and they'll be pre-filled on every new product — you'll just tweak the values per item.

## Add a size chart

Clothing buyers often want measurements. On the product, add an **Info image** (it shows as a *Size Chart* popup). You can rename that popup's default label under **Settings → Pages & policies** — see [Policies & products page](https://sitesplaced.com/help/md/online-stores/pages-and-policies.md).

**Q: I only see one price box — where are options?**

Scroll to the Options section on the product. If you also want a different price or separate stock per option, switch the models on first under Settings → Catalog & fields (Step 1).

**Q: Can different sizes share one stock number?**

Yes — set Stock tracking to 'One stock count per product'. The whole product shares a single count regardless of options.

**Q: A customer can't buy a size that's in stock — why?**

Check that the variant row has stock and isn't removed. Stock is enforced per variant when you track 'Stock per option'.
