Door Jamb Depth and Finished Wall Thickness
A wall measurement without its finish build-up is not enough to finalize a door frame.
Direct Answer
Jamb depth should be reviewed against the finished wall thickness, including board, tile, plaster, trim and other layers that the frame must cover.
What jamb depth describes
Jamb depth describes the frame dimension across the wall, not the door leaf thickness. The review should identify the finished wall thickness and whether the jamb is fixed, adjustable or supplied as part of a complete set.
Wall build-up checklist
- Structural or framed wall thickness.
- Board, plaster, tile or panel layers.
- Finished floor and threshold relationship where relevant.
- Trim and architrave coverage.
- Any variation between room types or floors.
Avoid a nominal-only quotation
Two rooms can have the same leaf size but different wall build-ups. Keep jamb depth and wall thickness in separate schedule columns, then flag any opening where the site condition is not confirmed.

Buyer questions
No. Compare jamb depth with the finished wall build-up that the frame and trim must cover.
It may help where the selected product supports it, but the project still needs a confirmed wall range and installation detail.
Send a section, marked-up photo or drawing showing all finish layers and the intended frame and architrave coverage.
