Ideal room temperatures

The perfect room temperature can be tricky to achieve, particularly if you live with a number of people. But that doesn’t mean it’s not achievable.

While there is no one-size-fits-all answer, the optimal temperature depends on the individual’s preferences, the season, and your home’s climate.

The first step in finding the ideal room temperature is to determine what temperature is most comfortable for you. Most people prefer temperatures between 20-22°C. If you find yourself feeling too hot or cold, you can adjust the temperature a few degrees up or down to find the ideal level of comfort.
