Planning estimate: This list describes two sides, a captured top and bottom, adjustable shelves, and two narrow rails. A structural back, fixed shelf, base, face trim, anti-racking details, and anti-tip anchoring must be designed separately.

Visible arithmetic

captured width = outside width − (2 × measured side thickness)

This list describes two sides, a captured top and bottom, adjustable shelves, and two narrow rails. A structural back, fixed shelf, base, face trim, anti-racking details, and anti-tip anchoring must be designed separately.

Use the generated rectangles as a transparent starting point. The layout does not replace a construction drawing, hardware specification, load calculation, or safe cutting procedure.

Before material purchase

Checks the calculator cannot make from dimensions alone

Check shelf deflection for the intended load and clear span.
Add a structural back or another anti-racking system.
Confirm wall anchoring and anti-tip requirements.
Recalculate after adding a fixed center divider or hardwood shelf nosing.
