The ideal temperature for a refrigerator should be between 35°F and 38°F (approximately 1.7°C to 3.3°C), with the optimal temperature often recommended at around 37°F (3°C). This range keeps food fresh and safe by slowing bacterial growth without causing food like vegetables to freeze. The temperature should never exceed 40°F (4.4°C) to ensure food safety. For practical purposes, many sources recommend setting your fridge around 37°F (3°C) to 38°F (3.3°C). Some UK guidance suggests a slightly broader range of 0°C to 5°C (32°F to 41°F), but it is ideal to keep it closer to the lower end of that range to prevent food spoilage. It's also important to note that fridge temperatures can vary inside, with door compartments usually warmer and lower shelves colder, so keeping a fridge thermometer can help ensure accuracy. In summary:
- Recommended fridge temp: 35°F–38°F (1.7°C–3.3°C), ideally around 37°F (3°C)
- Max fridge temp for food safety: 40°F (4.4°C)
- Keep fridge well-stocked but not overloaded
- Avoid placing hot food directly inside
- Regularly check door seals for efficiency
This temperature range helps keep food fresh longer and reduces risk of illness from bacterial growth.
