About room temperature and TOG
Many parents like to keep a baby’s room comfortable and to match clothing or a sleep bag to the room temperature. Sleep-product makers commonly publish TOG and clothing charts for different room temperatures, and a frequently cited comfortable band is about 16 to 20 °C (68 to 72 °F). This page gathers that general guidance in one place so it is easy to look up.
This is comfort guidance only and not a safety rule. For a wider home comfort check, try the room comfort checklist, and to keep a private record of readings see the room temperature tracker.
