Measure the deepest intended objects
Check oversized books, baskets and display pieces separately from ordinary books. Include protruding handles or stands. The deepest object may justify a larger shelf, but one occasional item need not dictate the depth of an entire wall of storage.
Decide whether double rows suit you
Putting books in front of other books increases capacity while making the rear row harder to browse. Try that arrangement with the real collection before treating it as an advantage. If forgotten books frustrate you, shallower single-row storage may be more useful.
Check the room at the floor edge
Tape the outside depth including legs or feet. Walk from the doorway past the shelf while another person sits nearby. A tall narrow unit can still create a substantial obstacle if its base projects into the room’s busiest strip of floor.
Plan display without unnecessary depth
A few objects may look good with space around them, but extra shelf depth is not the only way to create that arrangement. Compare the object’s actual footprint with the clear shelf. Buy the larger unit when it serves possessions, rather than assuming deeper always looks more generous.
For illustration, ordinary paperbacks might fit a shallower shelf while one large basket requires a deeper one. Storing that basket elsewhere can preserve a useful floor strip along the entire bookcase wall.
