Perler Bead Pegboards: Shapes & Which to Buy

Perler bead pegboards come in a handful of shapes — square, round, hexagon, heart and star — and the shape you pick changes how you design, not just how the finished piece looks. This guide covers what each board is good for, which one a beginner should buy first, how the interlocking boards join, and the one thing most people miss: a shaped board is not a plain rectangle.

What a perler bead pegboard is

A perler bead pegboard is the plastic peg grid you stand fuse beads on, one bead per peg, before you fuse them with an iron. The pegs hold each bead upright and spaced so that when the heat melts the rims, every bead bonds to its neighbors and the whole design lifts off as one rigid panel. The board is a jig; it never gets fused into the piece.

Perler is the dominant brand in the United States, and its boards are clear so you can slide a printed pattern underneath and place beads straight over it. The pegs sit on a fixed pitch of about 5 mm, the same as a midi bead, which is why Perler, Hama Midi, and Artkal S beads all share the same boards. What changes from board to board is the outline — the shape the pegs are cut into — and whether the board interlocks with others.

Get the shape right and the design almost plans itself. Get it wrong and you either waste half a board or find your rectangle spilling off the edge with nowhere to go.

The default: the clear square pegboard

The workhorse is the large clear square board. Perler's standard size is 29 pegs by 29 pegs, measuring about 5.7 inches across, which is a comfortable coaster-to-small-panel footprint. A fully packed square is 841 beads.

Two things make it the default. First, it interlocks: the edges carry tabs and slots, so you snap boards together to build past a single board's limit. Four of them lock into an 11.4-inch square that holds up to 3,364 beads. Second, its geometry is the friendliest possible. A square peg grid has no row offset and square cells, so a plain chart maps one cell to one peg with no correction — exactly the grid a perler bead pattern maker outputs. If you own one board, buy the square.

Perler also sells a small square at about 3.125 inches (roughly 16 by 16 pegs) for keychains and quick pieces, but it does not interlock. For anything you plan to grow, the large interlocking square is the one to stock.

Perler pegboard shapes compared

Beyond the square, Perler bundles four shaped boards, most commonly in a clear five-shape set: square, circle, hexagon, heart and star. The shaped boards are standalone — they carry no interlocking tabs — so each one produces a single piece at its own fixed size. Dimensions below are Perler's stated footprints; peg counts are approximate, derived from the footprint at 5 mm midi spacing.

A few notes that decide which shaped board earns a spot in your kit. The round perler bead pegboard is the most versatile shaped board because so many designs are radial: coasters, wreaths, clock faces, and mandalas all want a circle. The hexagon pegboard is the sleeper pick — hexagons tessellate, so you can build a run of them into a honeycomb wall without the seams a square grid shows. Heart and star are single-purpose: great for the thing they are, not much use otherwise.

Note that Perler mixes small and large boards within a single shapes pack, so the heart and star you get are smaller than the square in the same box. Check the footprint before you plan a design to a specific bead count. If you are unsure how physical size relates to bead count, our guide to perler bead sizes converts millimeters to beads per inch.

Why a shaped board is not a rectangle

Here is the practical point nearly every beginner learns the hard way. A pattern for a shaped board is not a plain rectangle you crop to fit. The usable pegs form the shape, so you have to plan the design to the board's real outline, or it will not sit right.

Round boards make this sharpest. The pegs sit on concentric rings, not straight rows — the board is ring-indexed. Each ring holds a different number of beads than the one inside it, so you plan the design ring by ring, outward from the center, the way you would read a radial chart rather than a grid. Drop a square 20-by-20 chart onto a round board and the corners have no pegs to land on; the design has to be authored round from the start.

Hexagon, heart and star boards are outline-indexed rather than ring-indexed: the pegs still line up in rows, but the rows get shorter or longer as the outline narrows, and the four corners of a rectangle simply are not there. Either way, the takeaway is the same — a shaped board wants a design shaped to it, planned to the board's actual peg layout, not a rectangle you hope will fit.

Interlocking pegboards and building bigger

When a design outgrows one board, the answer is interlocking pegboards. Only the square boards carry the tabs, and they only join to other square boards. The join is seamless as long as you plan the design across the whole multi-board area first, so no motif lands on a seam where two boards' edge pegs meet.

Practical limits worth knowing before you buy a stack:

• Four boards, one panel. A 2-by-2 array of large squares is 58 by 58 pegs, about 11.4 inches, and up to 3,364 beads. That is the sweet spot for wall art and larger portraits.
• Support the panel when you move it. A large interlocked layout of loose, unfused beads flexes at the seams. Slide a tray or stiff card underneath before you carry it to the iron.
• Shaped boards do not extend. If you want a design bigger than a single heart or star, you are switching to mini beads for more detail in the same footprint, not adding boards.

This is where charting ahead pays off. Because the square grid maps one cell to one peg, you can plan a four-board build as a single 58-by-58 chart and simply know which quadrant each board covers.

Are perler pegboards interchangeable between brands?

Mostly yes, with one trap. At midi size the peg pitch is a shared 5 mm, so Perler, Hama Midi, and Artkal S boards and beads mix freely — a Perler board holds Hama beads and vice versa. Builders lean on this to reach colors one brand does not carry.

Mini size is where boards stop being interchangeable. Hama Mini beads run slightly smaller than Artkal Mini, so a mini board from one brand can leave the other brand's beads loose enough to pop off, or too tight to seat. Stay within one brand for mini work. The full rundown of which beads and boards mix is in Perler vs Hama vs Artkal.

Which perler pegboard should you buy?

Match the board to what you actually make, not to the biggest set on the shelf.

• Just starting? One large interlocking square. It handles every rectangular sprite and grows when you are ready.
• Making coasters or mandalas? Add a round board. Radial designs need real rings, not a cropped square.
• Into geometric or tiled art? The hexagon board tessellates into honeycomb runs a square grid cannot fake.
• Gifts and seasonal pieces? The heart and star boards are cheap single-purpose add-ons; buy them with the five-shape pack rather than alone.
• Building big? Buy squares in multiples so they interlock. Two 2-packs give you the classic four-board panel.

The order most people settle into: one square, then a round, then whatever shape their projects keep asking for.

How Beadify helps

Most pattern tools only design for the square board, which leaves the round, hexagon, heart and star boards as guesswork. Beadify designs directly onto real shaped pegboards: pick a round or hexagon board and it generates a chart that follows the board's actual peg layout — ring by ring for a round board, along the outline for the others — instead of handing you a rectangle you have to crop by eye. You can even drop a random pattern onto a shaped board when you want a starting point. Almost no other tool does shaped boards, and it is the fastest way to design straight onto a round or hexagonal pegboard.

For the square board it is just as direct: the loom grid maps one cell to one peg, so the chart is already a pegboard map. Shaped-board design lives on the Pro plan, and there is a free 7-day Pro trial with no card required, which is enough to chart a round coaster or a hex tile end to end and export the PDF.
