Final target panel width after trimming and squaring.
in
Final target panel length after end trimming.
in
Panel thickness used for board-foot, glue-line area and waste calculations.
in
Ripped strip width after jointing or sizing. Wider strips reduce glue lines but can show more cup or grain mismatch.
in
Usable board width before ripping panel strips.
in
Purchased board length. It must be at least the finished panel length plus end trim.
ft
Extra width left on each outside edge for final ripping, jointing or squaring.
in
Extra length left on each strip for squaring, snipe, defects or final trimming.
in
Material lost between ripped strips on the same rough board.
in
Target spacing between clamps along the panel length.
in
Estimated purchase price for one rough board at the entered width and length.

Method notes 4 notes
  • Target blank width = finished panel width + 2 x side trim allowance.
  • Strip count = ceiling(target blank width / strip finished width). Rough boards to buy = ceiling(strip count / strips per rough board).
  • Clamp count = ceiling(strip cut length / target clamp spacing) + 1, with at least two clamps.
  • This is a takeoff and layout screen only. It does not optimize grain matching, color, growth-ring orientation, cup/crook, moisture conditioning, adhesive open time, cauls, clamp pressure or final flattening.
