Setting up sizes and colors (variants)

If one shirt comes in S, M and L and in red and blue, don't create separate products — add variants to one product. Customers choose the size and color on the product page, and every combination has its own stock.

Step by step

1. On the Products page, create a product or click Edit on an existing one.
2. Tick This product has sizes / colors.
3. In the first box, type the option name, e.g. Size.
4. In the next box, type the values separated by commas, e.g. S, M, L, XL.
5. Need another option? Click + Another Option (e.g. Color) and fill it in, e.g. Color → Red, Blue, Black.
6. A list of every combination appears below (S / Red, S / Blue…). Set the Price, Compare-at price, Stock and SKU for each.
7. Save with Add or Update.

Limits

• Up to 3 options per product (e.g. size, color, fabric).
• Up to 30 values per option.
• Up to 100 combinations in total.

Stock and orders

• Each combination has its own stock. Selling M / Blue only lowers that one.
• When a combination is at 0, its buy buttons are switched off; the others can still be bought.
• Orders and printed invoices show the choice next to the name, e.g. "T-shirt (M / Blue)".
• Customers can't add to cart without choosing, so wrong-size orders drop.

FAQ

Can I add a new size later?

Yes. Edit the product, add the new size to the option's values (comma separated), then set stock for the new combinations.

What happens if I turn variants off?

Untick the box and it becomes a simple product again, with one price and one stock. Sizes and colors on earlier orders stay in the records.
