Welcome back
Pick up where you left off.
See your new floor before you buy a board
Stagger works out where every plank and every joint goes, so the pattern never repeats and you buy the right number of boxes. Pick a room and look:

Trusses
Available stock — enter qty the supplier has
Enter the quantity for each length you have. Leave blank (or 0) for lengths you don't have. Offcuts are only reused within the same length.
Boards & buffer
Generates 6 non-repeating layouts to flip through — every joint on a truss, adjacent rows never share a truss, 2-truss spacing preferred, rows two apart share at most one.
Pine estimates only — cull damaged ends as you go.
Room
Run planks along the longest wall. Measure the finished floor, not the subfloor.
Plank
Laminate print repeats every 6–10 planks. Pulling straight from one box makes the floor read fake — rotate across open boxes.
Stagger rules
Joints must clear both the row above and the row two above. Check the plank maker's minimum — most require 12″ or ⅓ plank length.
Buy the boxes the layout actually needs, then add your own buffer for breakage.

Each job holds its own areas, totals and materials.
Read-only
Nothing on this screen changes anything. It reads both copies of your data and reports what it finds.

Storage
Your jobs are saved in the older storage. Nothing has been changed yet — this is only a look at what was found. Download a backup first if you like, then bring them across. The old copy is kept either way.
Job
Add each area of the job — a room, a hallway, a bedroom. You'll get a per-area and a whole-job total.
New area
Pick the closest match — you'll set the exact sizes next.
Drag a room to move it — rooms snap together. Drag a corner to resize.
Measurements
Tap a side number on the diagram, type its length, and it lands beside that side.
