Nursery Calculators & Guides
Keep the nursery comfortable. Check humidity and plan a cosy, healthy room.
A comfortable nursery helps everyone sleep better. Air that is too dry can leave babies with stuffy noses and dry skin, while air that is too humid can encourage mould. Our humidity calculator checks your nursery against the recommended 40–60% range and estimates how long a humidifier might run to reach your target.
For the full picture on a cosy room, read our baby room temperature and humidity guide.
The most reliable tool of all is an inexpensive hygrometer. Place one in the nursery to see real readings, and use our calculator to plan adjustments.
