Shopify product filtering setup

Where filters get their values

Shopify's documentation lists Availability, Category, Price, Product type, Tags and Vendor as standard filters, with custom filters based on product options, metafields or metaobjects.

Limits to plan around

Shopify's documentation sets several limits on storefront filtering: up to 25 filters for the store, up to 100 values displayed per filter, and no filters on collections containing more than 5,000 products. These rarely matter for small stores but shape planning for large ones. A collection of more than 5,000 products may need splitting into smaller collections for filters to appear.

Choosing a focused set of genuinely useful filters is better practice anyway; long filter lists overwhelm shoppers, especially on phones.

Preparing the data

Why metafields often beat tags

Tags are quick to add but easy to get wrong: misspellings, duplicates and tags left over from old campaigns all appear as filter values. Metafields store attributes in defined fields, often with a fixed list of allowed values, which keeps filters clean. For attributes such as material, room or compatibility that shoppers filter by, metafields are usually the more reliable source.

How filters appear to shoppers

• Theme controls display

  Filters are configured in the app but shown by the theme, typically in a sidebar on desktop and a panel on phones.

• Order matters

  Put the filters shoppers use most at the top.

• Value labels

  Use shopper-friendly labels, not internal codes.

• Applied filters visible

  Shoppers should see and remove what they have applied.

Choosing which filters to offer

Start from how shoppers decide. Site search terms, customer questions and the attributes your best sellers differ by all point to useful filters. Price and availability are useful almost everywhere; size and colour for clothing; dimensions and material for furniture; compatibility for parts. Filters that nobody uses add clutter and can be removed.

Keeping filters clean

Filters drift as products are added by different people. A short product-adding guide that lists which fields to fill and the allowed values keeps new products consistent. A quick quarterly look at filter values catches stray spellings before they multiply.

Price and availability filters

Price and availability filters are useful in almost every store and need no extra data. Showing only available products is particularly helpful in fashion and other ranges where sizes sell out: shoppers who filter by size usually want items they can actually buy. Consider whether availability filtering should be visible as an option or whether sold-out items should be handled through sorting instead.

Price filters work best when the range of prices in a collection is wide enough to matter.

Value lists that make sense

A filter with too many values is hard to use, and Shopify displays at most 100 values per filter. Grouping fine-grained values, such as twenty shades of blue, into broader shopper-friendly groups can make a colour filter far more useful while the product page still shows the exact shade name.
