Perler Pegboard Sizes: 29×29, Multi-Board & Pattern Width

When you plan a fuse-bead build, “board size” is peg math—not a shopping cart. Large square pegboards commonly use a 29×29 peg grid. Knowing that convention helps you set pattern width in PixoMosaic so the chart matches the boards you will place. This guide stays on category sizing and multi-board layouts for Perler-style fuse beads (and the same peg math makers use with Hama or MARD stock). It does not rewrite color-matching advice.

What 29×29 means

In maker language, a 29×29 board commonly means 29 pegs on each side. A full grid is 29 × 29 = 841 peg positions. That figure is a capacity ceiling for one large square board—not a promise that every chart fills every peg. Empty cells need no beads.

PixoMosaic is a free Image to Bead Pattern tool for Perler-style fuse beads. Brands named in product planning are Perler, Hama, and MARD. Pegboard dimensions here are described as commonly or typically used in the craft; they are not claimed as official affiliation with any brand.

One vs multi-board (29 / 58 / 87)

Larger designs usually mean multi-board layouts. A practical rule for how many pegboards you need:

ceil(width ÷ 29) × ceil(height ÷ 29)

Work the formula on both axes, then multiply. Examples in pegs:

• 29 × 29: 1 × 1 → 1 board
• 58 × 58: 2 × 2 → 4 boards
• 87 × 87: 3 × 3 → 9 boards

A 58×58 chart is two boards wide and two tall—four boards total—if you stay on the 29-peg module. Gaps at the edges still count as empty pegs: leave them bare. If your art is 40 beads wide, ceil(40 ÷ 29) is still 2 boards across; place only 40 columns and leave the rest empty.

Finished size ~5 mm → ~14.5 cm

Midi-style fuse beads are commonly about ~5 mm across before ironing. A full 29×29 field therefore lands near ~14.5 cm (~5.7 in) on a side before ironing—again typically, not a guaranteed finished measurement after melt and cool. Ironing, paper, and board brand all change the final feel. Use the peg count for planning; treat centimeters as a rough scale check.

Pick width in PixoMosaic

Every size decision should land on pattern width (beads across) before you generate. Open the Image to Bead Pattern editor, upload your image, and set width so the preview grid matches one board (often 29) or a multi-board multiple (58, 87, and so on). Then check height and totals. For how palette limits interact with grid size, see Bead Palette and Pattern Size.

Large designs in sections

Very wide charts are easier when you build section by section—one physical board or quadrant at a time—while following the same master grid. Read counts and export a printable guide so each section stays aligned; see How to Read and Export Your Bead Pattern.

Start with the right width

Set pattern width to your board module, preview the grid, then generate. Open PixoMosaic when you are ready, or skim the FAQ for common pattern questions.
