Loom stitch
Rows sit square on the loom, so the chart is a straight grid: one bead per warp gap, one row per pass of the weft. What you draw is what you weave, bead for bead.
Loom and square stitch share the same geometry, so a chart drawn here works for both. Because the grid is straight, a 24 × 40 cuff is exactly 960 beads and the finished size is the bead size times the count, which is how the editor reports it.

Reads left to right, one row per line, the way you pick beads onto the needle for each weft pass.
