How to Use the Newborn Indoor Outfit Calculator
This tool takes the indoor temperature and recommends the right newborn outfit thickness and layering for home. Because newborns regulate their body heat less effectively than adults, knowing the right outfit for the room temperature matters.
Outfit Guidelines by Indoor Temperature
72-75°F is the most recommended range for a newborn, where a single long-sleeve onesie is standard. Above 79°F, a short-sleeve onesie alone is enough, while below 68°F you'll want a thick onesie, a swaddle, and possibly more room heat.
How to Check Your Baby's Temperature
Cool hands and feet are normal for newborns and aren't a reliable guide for dressing. Feel the back of the neck or upper back instead — warm and slightly damp is ideal; remove a layer if sweaty, add one if cool.
