The number of products within a terminal category.
SKU counts are important to consider when building a hierarchy or when designing schema. If a category with a SKU count of 5 has a sibling with 5,000 SKUs that may be a sign of hierarchy imbalance. In addition, the 5,000 item category is likely going to need a more complex series of attributes to govern the items. However, high SKU count does not tell the whole story, as considerations like revenue balance and department oversight should also go into hierarchy decisions. SKU count is also important to take into account when creating a timeline for projects, as the higher the SKU count, the more complex each category tends to become.
