Cell & calibration

1 · Calibrate screen — once per device

Pixels aren't enough: every screen has a different density. Hold a ruler against the bar and type how many mm it spans edge to edge (mark to mark). That makes each cell the same physical size on any device.

← measure edge to edge →

Measured length (mm)

Status

Not calibrated

2 · Physical cell size

6.0 mm

Measure one cell of your cardboard template and enter that value. The 10×10 block on screen is ≈ 60 mm. Press O / L to resize by 0.1 mm. The thicker marks every 10 help you align.

Export

Only numbers travel ID:Offset. Plain text never touches the device.

Import

Paste the sender's payload. The matrix rebuilds and freezes so you can read it with your template.
