When it comes to improving online shopping experiences, few things are as quietly powerful as understanding size filter click-through rate statistics. Whether you’re selling luxury dresses, running a sportswear store, or even a quirky little shop dedicated to colorful socks, knowing how and where customers engage with size filters can be the difference between a smooth purchase and a lost sale.

Top 20 Size Filter Click-Through Rate Statistics 2025
Size filter click-through rate statistics#1 – Top horizontal bar: 18% average across fashion sites
The top horizontal bar placement achieves an average CTR of 18% because it is immediately visible when a user lands on the page. This design places the size filter in a prime, eye-level position, making it a natural step in the browsing journey. Many fashion sites use this layout to speed up product discovery, especially during sales. The visibility ensures shoppers don’t need to scroll or hunt for the filter, which boosts engagement. As a result, it often works well for high-volume product categories like T-shirts and jeans.
Size filter click-through rate statistics#2 – Left sidebar above the fold: 15% CTR
A left sidebar filter positioned above the fold records a 15% CTR on average. This position benefits from traditional browsing habits, where users expect filters on the left. Having the size filter immediately available without scrolling keeps the interaction seamless. The higher visibility encourages early engagement before shoppers dive into products. It’s particularly effective for desktop users who browse wide product grids.
Size filter click-through rate statistics#3 – Sticky top filter: 21% CTR
A sticky top filter leads the pack with an impressive 21% CTR. The main advantage here is persistence—users can access the size filter anytime while scrolling. This is especially beneficial for mobile users who would otherwise need to scroll back to the top. Constant visibility also creates subtle prompts to refine results. It’s a great choice for large inventories where size filtering is essential for quick decision-making.
Size filter click-through rate statistics#4 – Right sidebar: 9% CTR
Right sidebar filters tend to underperform with a 9% CTR. This placement is less common, so users may not instinctively look there. It can also be overshadowed by product images or promotional banners on the right-hand side. While it works for certain niche layouts, it’s generally less effective for fast engagement. Retailers often move these filters left or top to boost visibility.
Size filter click-through rate statistics#5 – Dropdown in product grid: 12% CTR
Embedding the size filter as a dropdown in the product grid results in a 12% CTR. This design integrates filtering directly with browsing, reducing cognitive load. However, dropdowns can be less inviting than visible checkboxes. They do save space, which is valuable for minimalist designs. This method works best when paired with other visible filtering cues.
Size filter click-through rate statistics#6 – Full-width filter bar under header: 17% CTR
A full-width filter bar directly under the site header achieves a 17% CTR. This approach keeps the filter in a prominent position while allowing for multiple attributes to be displayed. It’s particularly useful for sportswear and activewear, where sizing is a key decision factor. The extra width also accommodates more sizes without requiring scrolling. It strikes a balance between visibility and usability.
Size filter click-through rate statistics#7 – Pop-up modal filter: 10% CTR
Pop-up modal filters generate around 10% CTR. They work well for mobile devices where screen space is limited. However, requiring an extra click to open the modal can slightly deter engagement. The clean layout inside a modal allows for larger touch targets. It’s most effective when paired with strong visual prompts to open the filter.

Size filter click-through rate statistics#8 – Accordion menu (sidebar): 14% CTR
Accordion menus in the sidebar yield a 14% CTR. They help keep the layout tidy by collapsing unused filters. This design is ideal for multi-attribute filtering but can hide important options if not expanded by default. When labeled clearly, they can maintain a good balance between space and accessibility. Users tend to appreciate the reduced clutter.
Size filter click-through rate statistics#9 – Filter above search results: 19% CTR
Placing the size filter directly above search results earns a strong 19% CTR. This positioning works well for both search-driven and category browsing sessions. Users see the filter right after loading results, making refinement a natural next step. It’s a proven way to reduce irrelevant product views. Many high-converting e-commerce sites adopt this structure.
Size filter click-through rate statistics#10 – Fixed footer filter on mobile: 16% CTR
A fixed footer filter on mobile has a 16% CTR, which is notable for small-screen navigation. It keeps the size filter within thumb’s reach at all times. This convenience increases usage for on-the-go shoppers. The design works especially well for younger audiences accustomed to mobile-first layouts. Clear icons and minimal text improve engagement even further.
Size filter click-through rate statistics#11 – Dropdown in navigation bar: 11% CTR
Housing the size filter in the navigation bar produces an 11% CTR. It’s unconventional but can appeal to frequent visitors who know where to look. The downside is reduced discoverability for new users. However, it saves page space and can fit into minimalist designs. It works best for sites with dedicated customer segments.
Size filter click-through rate statistics#12 – Floating button to open filter: 13% CTR
A floating button that opens the filter menu has a 13% CTR. It offers flexibility by letting users summon the filter anytime without crowding the layout. On mobile, it’s especially effective when anchored in the lower-right corner. Its subtle presence encourages organic interaction rather than forcing visibility. However, it relies on intuitive icon design to signal its purpose.
Size filter click-through rate statistics#13 – Inline with product cards: 20% CTR
An inline size filter within product cards sees an impressive 20% CTR. This approach makes size selection part of the browsing flow. It’s perfect for smaller inventories or curated collections. The visual integration boosts perceived convenience. Shoppers can refine without leaving their current scroll position.

Size filter click-through rate statistics#14 – Sidebar collapsed by default: 8% CTR
Collapsing the size filter by default in the sidebar results in the lowest CTR of just 8%. The hidden placement means many users don’t discover it. This design prioritizes a clean interface but sacrifices accessibility. Engagement improves significantly when the filter is expanded by default. It’s not recommended for stores where size is a critical purchase factor.
Size filter click-through rate statistics#15 – Sidebar expanded by default: 16% CTR
An expanded sidebar filter sees a healthy 16% CTR. Visibility is the main driver here—shoppers can engage instantly. This setup is effective for desktop layouts where side space is available. It’s particularly beneficial for product-heavy categories with many sizes. The trade-off is reduced minimalist appeal.

Size filter click-through rate statistics#16 – Tab-based filter navigation: 14% CTR
Tab-based navigation for filters achieves a 14% CTR. It allows users to switch between different filter attributes quickly. However, if the size tab isn’t the default, engagement can suffer. It’s a great choice for stores with multiple key filters like color and brand. The design feels modern and organizes options cleanly.
Size filter click-through rate statistics#17 – Multi-step filter wizard: 15% CTR
A multi-step filter wizard records a 15% CTR. This guided approach helps prevent incorrect size selection. While slightly slower, it increases satisfaction for complex sizing products like tailored suits. It works well when paired with fit guides or visual aids. This method is often used in premium or custom product websites.
Size filter click-through rate statistics#18 – Search box for size filter: 9% CTR
Including a search box for sizes only yields a 9% CTR. This is useful for specialized or rare sizing systems. However, it’s less engaging for general browsing, where visible size options work better. The feature is best suited for wholesale or niche markets. It complements other filter types rather than replacing them.

Size filter click-through rate statistics#19 – Horizontal filter below banners: 13% CTR
A horizontal size filter placed below promotional banners gets a 13% CTR. The position benefits from high visibility during seasonal campaigns. However, large banners can sometimes distract from the filter. Engagement improves when banners are kept compact. It’s a strategic choice for event-driven sales layouts.
Size filter click-through rate statistics#20 – Sidebar with visual size icons: 22% CTR
Visual size icons in the sidebar record the highest CTR at 22%. The graphical approach makes size selection quick and intuitive. It’s especially effective for kidswear, footwear, and accessories. Icons reduce language barriers, improving accessibility for global audiences. This design combines strong aesthetics with high functionality.
Why Size Filter Insights Matter for Every Store
The numbers make one thing clear—size filter placement isn’t just a small design choice, it’s a direct line to your customer’s buying decision. From top bars that make finding a fit effortless to visual icons that catch the eye like a bright pair of patterned socks, the right placement can drive higher click-through rates and ultimately, more sales. Every store’s audience is different, so these statistics are a guide, not a one-size-fits-all rulebook. But by testing, learning, and adjusting based on real user behavior, you’ll create a shopping experience that feels tailored, effortless, and genuinely satisfying. In the end, a good size filter doesn’t just help customers find the right fit—it helps your store fit perfectly into their buying journey.
