This document provides a list of hotel brands and chains categorized by their 2015 chain scale: luxury, upper upscale, upscale, upper midscale, midscale, and economy. The chain scale is determined by the previous year's average daily rate for each chain worldwide and defines six distinct tiers. A total of 1687 hotel brands and chains are included in the list slotted into their respective chain scale based on average rate. The list is a subset of STR Global's larger chain scale reference and brand categorizations are consistent between the two lists.
