Bookshelf Tips
Planning for tallest books first helps avoid awkward dead space and rework later.
Ignoring divider thickness can produce tighter final clearances than expected.
Too-deep shelves waste volume; too-shallow shelves limit what can be stored.
For an 84-inch case with 6 openings and 0.75-inch boards:
Clear Spacing
13.4 in
Top Clearance
12.1 in
Depth Target
11 in
The calculator subtracts shelf divider thickness from total case height, then distributes the remaining usable vertical volume across shelf openings. Depth recommendations are based on storage type.
