Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocolcurrently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average cold sleeper comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average warm sleeper comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for womens bags, to the Lower Limit rating for mens bags, or somewhere in the middle for nongendered bags.
