How much weight can floating shelves hold?

When anchored into two or more studs, a floating shelf can hold 30 to 50 pounds depending on span and design.

How far apart should floating shelves be?

Space 8-12 inches apart for books, or 12-16 inches for decorative objects.

Can I build them without a stud finder?

You can tap the wall or use a magnet to find screws, but a stud finder is inexpensive and recommended.
