What is the Normal House Temperature for Babies, Pets, and Everyone Else in the Home?

With most of us spending a lot of our time at home, it’s vital to keep our houses at an optimal temperature.

So what is the optimal temperature for the home, and how can you keep it at that? Let’s find out.

What is the Average Room Temperature?

The average room temperature is between 68 and 72 degrees Fahrenheit or 20 and 22 degrees Celsius. A National Renewable Energy Laboratory study revealed that the average residential indoor temperature is between 67.2 and 74.6 degrees Fahrenheit or 19.5 and 23.7 degrees room temp Celsius.

It is worth noting that room temperature reflects the degree of comfort people feel indoors. An ‘optimal temperature’ would mean that they aren’t sweating or shivering wearing normal daily attire, such as t-shirts, shorts, and plain dresses.

Of course, temperature is subject to preference. One person might complain of feeling cold while another might be too warm. Hence, ideal room temperature is relative to one’s subjective comfort levels.

What is an Ideal Temperature for a House?

The ideal temperature for a house varies from room to room. For example, families with young children might consider installing a thermostat in their nurseries to better regulate the ambient temperature, and those with pets might want to consider their comfort needs as well.

In this section, we’ll look at the different room temperature requirements for babies, pets, and the different seasons.

Ideal Room Temperature for Babies

EnvironmentRecommended Temperature 
Nursery temperature in general18°C or 64.4°F
Baby rooms during summertimeAround 21°C or 69.8°F
Rooms with young infants under six months oldAt least 15°C or 59°F

Most parents set the nursery thermostat between 18 and 22 degrees Celsius. This room temp in C is equivalent to 64.4 and 71.6 degrees Fahrenheit. 

Hence, parents must ensure a comfortable room temperature for babies to promote healthy growth and development during sleep.

Ideal Room Temperature for Pets

Most pet parents worry about what temperature is ideal for dogs and cats. It is understandable because animals cannot regulate their body temperature as effectively as people. That is why dogs pant heavily during the hot summer and shiver in the winter. 

Although they have sweat glands on their paw pads, these are insufficient to regulate body temperature. Some breeds are also more susceptible to overheating than others. 

Particular BreedsRecommended Temperature
Short-haired dogs25.5°C ~ 26.8°C
78°F ~ 80°F
Most dogs in the winter20°C ~ 22.2°C
68°F ~ 72°F
Cats21°C ~ 31°C
70°F ~ 88°F

Cats have a higher heat tolerance than dogs. You can set your thermostat from 76 to 88 degrees Fahrenheit (24.4 to 31 degrees Celsius), and your feline friends will be just fine. 

However, cat owners should never let their cats stay in a room with an ambient temperature lower than 70 degrees Fahrenheit (21 degrees Celsius) because they cannot maintain their core body temperature.

Ideal Room Temperature during Summer

Many homeowners ask, what temperature should I set my air conditioner in summer? Common sense dictates cranking the thermostat to the lowest possible setting to make the home more comfortable. 

It can include using a ceiling fan to push cool air down. Shades, curtains, or blinds can also help lower ambient room temperature during summertime.

Weatherstripping windows and doors can also create a cooling effect in the summer, as does limiting the use of heat-generating devices and appliances.

Fluctuations in humidity and variations in clothing put the ideal summertime room temperature range between 68 and 74 degrees Fahrenheit or 20 and 23.5 degrees Celsius.

3 Factors That Could Influence Room Temperature

Several factors can impact ambient room temperature. In this section, we will examine the three most important ones.

Home DesignVentilation, heating, air conditioning, weatherstripping, window design, planning, building geometry, and number of floors can all impact room temperature.
InsulationQuality and density of insulating material can influence room temperature.
Home OrientationRoom temperature varies throughout the day as the sun moves across the sky, warming some rooms and cooling others.

Home Design

Temperature imbalances can occur in a poorly designed home. Unsurprisingly, architects spend a lot of time and effort planning essential elements for a modern house. Ventilation is crucial because it can contribute to efficient cooling in the hot summer. Meanwhile, weatherstripping can prevent unwanted heat losses in the winter.

Multi-level houses also have temperature variations across floors because heat moves upwards. You can expect the lower floor to be cooler than the upper sections. Leaky or wrong-sized HVAC (heating, ventilation, air condition) ducts or pipes can also influence room temperature. 


Poorly insulated rooms can have a negative influence on room temperature. Insulating materials must be thick enough to retain cool air in the summer and retain heat in the winter. Otherwise, you will spend more on cooling and heating the room during these times of the year. Proper insulation can help to reduce your bills by making heating more efficient.

Home Orientation 

Your house’s position relative to the sun can also affect room temperature. You can expect room temperature variations as the day progresses. One room might be cooler in the first few hours of the day and warmer in the second half, and vice versa, as the sun moves from east to west.

Would Smart Thermostats Help?

Smart thermostats automatically adjust the home temperature into energy-saving mode when nobody is home.


What temperature is too hot for a house?

Any temperature higher than 25.56 degrees Celsius or 78 degrees Fahrenheit is too hot for a house. However, it is worth noting that people living in naturally hotter climates lead normal lives despite the elevated temperatures. Places near the equator can have room temperatures as high as 88 degrees Fahrenheit, or 31 degrees.

Is 72 a good temperature for heat in the winter?

Yes, the Lansing State Journal considers 72 degrees Fahrenheit optimum, especially in the winter. Set your heater temperature to this level to ensure optimal heat generation. 

Why does my house feel cold at 70?

A house can feel cold at 70 degrees if it is inefficient. In other words, heat generated isn’t retained and is instead wasted. Pockets of cold air or drafts may be near the floor because of improper insulation, for example. An old filter, leaky ductwork, or a defective furnace can also make your house feel colder, even if the thermostat reads 70 degrees. 

Feeling cold can also be due to insufficient physical activity, preventing your body from generating the heat to feel comfortable.

What is the best temperature for heaters in winter?

The US Department of Energy recognizes 68 degrees as the best temperature for heaters in winter. The government agency further adds that homeowners should start with 72 degrees Fahrenheit or 22 degrees Celsius and gradually adjust the thermostat to more comfortable levels during the daytime. It is okay to dial down the nighttime room temperature to 66 degrees Fahrenheit or 19 degrees Celsius.

Should I turn off my thermostat when I’m away?

No, you should not turn off your thermostat when you are away because it can increase humidity and temperature levels inside your home. Instead, the US Department of Energy recommends adjusting the thermostat by seven to ten degrees Fahrenheit from the device’s normal setting for about eight hours. However, the government agency recommends turning off the thermostat when you are away during the summertime.

What is considered room temperature?

Any indoor temperature between 68 and 72 degrees Fahrenheit is room temperature. But, really, this depends on where you live. Some regions can have indoor temperatures as warm as 88 degrees Fahrenheit that would still be considered ‘normal.’

What is a good temperature to set your thermostat in the summer?

Seventy-eight degrees Fahrenheit is the recommended thermostat settings for summer use. This temperature is equivalent to 25.5 degrees Celsius.


Although the normal house temperature is between 68 and 72 degrees Fahrenheit or 20 and 22.22 degrees Celsius, you should remember that household members have varying room temperature requirements. 

Your home’s overall design, insulation, and orientation can greatly influence ambient room temperature. Installing smart thermostats is the most logical action if you want effective and convenient room temperature management, but structural fixes and alterations may be necessary to make your HVAC systems more efficient, saving you money in the long run.
