Shopify Collection Sort Orders Explained (2026, incl. Most Relevant)

Shopify collections support nine sort orders: Best selling, Product title A–Z and Z–A, Highest and Lowest price, Newest, Oldest, Manually, and — new with the 2026 collection model — Most relevant. The order you pick becomes the default arrangement of the collection page, the order most shoppers actually browse. What none of them consider: stock status. This explainer covers what each one really does and when to use which.

Where do you set a collection's sort order?

Per collection, in the admin: Shopify admin → Products → Collections → open a collection → the Products section has the sort dropdown. Smart (automated) and manual (custom) collections both have one. The choice applies to that collection everywhere it renders.

What does each sort order actually do?

Best selling

Orders by Shopify's internal sales rank — a moving measure of recent sales performance, not a lifetime total. Great default for discovery; its blind spot is stockouts: a product that just sold out was, by definition, selling well, so it often sits in the top row precisely when it can't be bought.

Product title A–Z / Z–A

Plain alphabetical order. Predictable, useful for parts catalogues and reference-style collections where shoppers scan for a known name — rarely the best merchandising choice elsewhere.

Highest price / Lowest price

Orders by price. Lowest-first suits value-led stores and sale collections; highest-first suits premium positioning. Note it uses the product's price as Shopify evaluates it — compare-at prices don't change the order.

Newest / Oldest

Orders by the date the product was created in Shopify — not published, not restocked. "Newest" powers new-arrivals collections; just remember that re-importing or duplicating products resets their place in it.

Manually

The only sort order that permits a custom arrangement. You drag products into position in the admin and the collection stays exactly that way — Shopify never rearranges it for you. That makes Manual both the most powerful order (any arrangement is possible) and the most expensive (every arrangement is your job to maintain). It's also the mechanism every merchandising and push-down app builds on: Sink, for instance, switches a managed collection to Manual and then maintains the arrangement automatically.

Most relevant (new in 2026)

Introduced with Shopify's 2026 collection model, and the default for collections created in the new collection UI. Rather than a single fixed attribute, it orders products by relevance. Like every other sort order, it doesn't consider inventory — a sold-out product can still rank high.

What does no sort order do?

Consider stock. There is no "In stock first" option, and no combination of the nine that produces one — a sold-out product keeps whatever position its title, price, sales rank, or manual placement earns it. If you want availability to matter, the only routes are maintaining a Manual order yourself or automating it. We've written up why that gap exists and the workarounds people try, and the three ways to push sold-out products down.

Three details that trip people up

• The shopper's sort dropdown wins — for that shopper. Your sort order sets the page's default. A shopper who actively picks "Price, low to high" in the theme's dropdown gets that order instead, sold-out items included. Most shoppers never touch it, so the default is what matters.
• Collection order ≠ search order. Storefront search results are ranked separately (and tuned via Shopify's Search & Discovery app). Sorting a collection doesn't change what search shows.
• Manual has practical size limits. Arranging thousands of products by hand isn't realistic, and programmatic reordering has limits too — Sink sorts up to 11,000 products per collection.

Which sort order should you use?

Whatever you choose, the stock-status gap applies equally — pair the rule with push-down automation and the collection stays truthful as well as well-ordered.
