Product variants (size, color) done right for a Lagos store (2026)

The verdict in three sentences

Variants multiply SKUs: a model in 5 sizes x 4 colors = 20 combinations to track separately. The right 2026 architecture is a parent product plus a variant matrix, each variant carrying its own SKU, stock, price and photo. Done right, stock stays accurate, checkout handles per-variant stockouts, and a size chart cuts returns by 10 to 25 %.

The data model that doesn't break

The classic mistake: tracking stock at the parent-product level. You think you have 30 sneakers but miss that only 2 are left in size 42. You must track stock per variant.

A clear SKU naming convention avoids chaos: TSH-RED-M, TSH-RED-L, TSH-BLUE-M. Readable in the warehouse and online alike.

Naming, stockouts and returns

At checkout, a zero-stock variant must be greyed out, never buyable then canceled: that is the top cause of Wave refunds and bad reviews.

Mini case study

Chidi, who runs a fashion store in Lagos, sells shirts in 4 sizes and 3 colors (12 variants). At first, stock was tracked at the parent: he showed "available" while blue M was sold out, driving ~18 % returns and cancellations. After switching to per-variant tracking with a size chart, returns fell to 11 %. On 200 sales/month at 12,000 FCFA, cutting returns by 7 points saves ~14 canceled sales, about ~168,000 FCFA/month of revenue preserved.

FAQ

How many variants can I manage? Technically unlimited, but keep it readable: beyond 30-40 combinations per product, group by ranges. Each variant keeps its own SKU, stock and price.

Can I set a different price per size? Yes. The base price sits on the parent, but each variant can adjust it, for example +2,000 FCFA for an XL or a premium finish.

How do I avoid selling a sold-out size? Stock is tracked per variant and checkout automatically greys out any zero combination, with an optional restock alert.

Does a size chart really cut returns? Yes: a cm-per-size table lowers returns by 10 to 25 % depending on category, because customers pick the right fit first time.

Do I need a photo per variant? At minimum one per color. The buyer wants to see the exact red before buying; a single generic photo raises returns and WhatsApp questions.
