Placement in a nursery is different from every other room. You're not just thinking about what looks good; you're thinking about what's accessible, what's safe, and what works as your child grows.
Low display shelves mounted at 24" to 30" from the floor put board books and picture books within reach for toddlers. A shelf at this height becomes part of how they interact with the room independently. Face-out display (spine facing up, cover facing out) works especially well at this height because kids navigate by cover art, not titles.
Mid-height shelves at 48" to 60" are the sweet spot for parents. Diaper supplies, extra blankets, small baskets, and decorative objects all work well here. High enough to be out of reach when needed, low enough to grab quickly during a nighttime change.
Higher display shelves above 60" are purely decorative at this stage. Stuffed animals, framed prints, sentimental objects, and things you want visible but not touched. These are the shelves that make the room feel finished and personal without adding clutter to reachable surfaces.
For depth recommendations across all three heights, the floating shelf depth guide covers everything in detail.
