Hidden bookcase door calculator: frame, hinge and shelves
A bookcase door is a cabinet that has to behave like a door. The hard constraints are weight and swing: the loaded case has to stay under the hinge rating, and the case has to clear its own trim through the whole arc of the swing.
This calculator is in build. It will size the case to your rough opening, budget shelf loading against pivot hinge ratings, and return a frame and shelf cut list along with the reveal and clearance dimensions the swing needs.
Estimates only — not a quote.

Plan it in 5 steps
- 1Measure the rough opening
Width, height and wall thickness all matter — the case has to live inside the wall and still swing.
- 2Budget the weight
Estimate the case loaded with books, not empty. Weight decides which pivot hinge you can use.
- 3Choose the hinge before the case
Hinge geometry sets required clearance and reveal, which then set the case dimensions.
- 4Plan the reveal
Consistent gaps around the case are what make the door read as furniture rather than a door.
- 5Verify the swing
Mock the arc on the floor with tape and confirm nothing in the room blocks the open position.
