Which BILLY Bookcase Length is Right for You?
Choosing the right length for your BILLY bookcase depends on the available space and your storage needs. Here's a guide to help you make an informed decision:

Small Spaces
If you're working with a small room or apartment, the 35 7/8" (91 cm) or 47 1/4" (120 cm) BILLY bookcase would be a great fit. These smaller sizes can fit perfectly into narrow spaces or alcoves, providing ample storage without overwhelming the room.
