Bead pattern size calculator for loom, peyote, and brick stitch

Width uses the estimated spacing of beads along a row. Loom length uses bead diameter per row. Peyote and brick stitch use an approximate 75% row pitch to account for staggered rows, with a half-bead allowance at the widest edge. Tension and bead shape can change real measurements; make a small swatch for a fitted piece.

Example: a 20 × 100 loom pattern
With Miyuki Delica 11/0, 20 columns are about 2.6 cm wide and 100 rows are about 16 cm long before findings or fringe.

Multiply the number of columns by bead spacing for width and the number of rows by bead diameter for length. Select your bead above to calculate both dimensions in centimeters.

Peyote and brick stitch stagger alternate rows, so their rows nest together instead of lining up like a loom grid. The calculator applies a simple staggered-row estimate, but the exact result depends on tension.
