Vertical filter panel

Vertical filter panels are a classic and widely recognized filtering tool. Unlike their horizontal counterparts, vertical panels can accommodate large numbers of filter groups, which makes them particularly suitable for desktop devices.

However, vertical filter panels take up valuable horizontal space, and research from the Baymard Institute shows that users sometimes overlook them entirely^[1]. On the other hand, horizontal panels can leave more space for product cards in a row, but they also tend to push the product grid lower on the page. This reduces what users see immediately above the fold, and a large filter block at the top can feel discouraging.

Space efficiency is therefore not measured only by the number of items that fit in a row. It is also about composition, balance, and visibility. The choice of filter panel type should depend on your requirements, the space available, and the number of filter options you need to support.
