Infinite pegboard turns a wall measurement into a single continuous board, then slices it into pieces your printer can make. The holes run uninterrupted across every seam, so once assembled the board behaves like one sheet. Included from Maker.

The same board engine powers SVG → pegboard and Text → pegboard: everything on this page about slicing, joints, mounts and separators applies to them too.

Wall and board

Wall width × heightDefault 1200 × 800 mmRange 100–6000 × 100–4000 mm: The free area you want to cover. Measure between obstacles — skirting boards, sockets, shelves — not the whole wall.
Wall marginDefault 0 mmRange 0–1000 mm: Space kept free inside that area on every side, for example to clear a door frame.
FitDefault Fill: Fill computes the largest board that fits inside the wall area, aligned to the hole grid so the holes sit evenly from the edges, and centres it. Custom lets you type the board size yourself.
Board width × heightDefault 1200 × 800 mmRange 60–6000 × 60–4000 mm: Only with Custom fit.
Corner radiusDefault 8 mmRange 0–200 mm: Rounds the four outer corners of the whole board. Seams between pieces stay square.

Slicing into pieces

The app divides the board into pieces no larger than your bed minus its margin, and keeps them balanced — similar sizes rather than full pieces plus thin slivers. For a 1200 × 800 mm board on a 256 mm bed that is about twenty pieces.

Seams always run through hole-free corridors, so they never cut a hole. On the capsule system the vertical corridors are 15 mm wide, but the horizontal ones are only 5 mm. So by default horizontal seams step around the slots: 20 mm up, 20 mm down, every 40 mm. Every piece keeps every slot intact with thick walls around it, and the steps help pieces align. If you would rather have straight lines, choose the Straight seam shape: the seam then runs through the 5 mm corridor itself, with thinner walls beside the slots, and short bridge strips glued across it on the back join the pieces. With the Stepped seam shape the vertical seams on the capsule system step too: each switches between two neighbouring 15 mm corridors, 20 mm apart, crossing the column in between through the gap between two of its slots every 40 mm, so the pieces interlock on all four sides.

On the capsule system, a straight cut at slot level would destroy a row of slots. The stepped seam weaves between them; the Straight seam runs through the 5 mm corridor between slot rows, with bridge strips (dashed) glued across it on the back.

With Stepped on the capsule system the vertical seam steps too, between two neighbouring 15 mm corridors through the gaps between slots, and meets each horizontal seam in the same corridor from above and below. Auto (left) keeps it straight.

LayoutDefault Grid: Grid lines up all seams. Brick offsets the vertical seams on alternate rows, like brickwork, so four corners never meet at one point. Brick is stiffer and hides seams better on large walls; use it for boards more than two pieces tall.
Seam shapeDefault Auto: Auto picks the best seam for your pegboard type: stepped where the straight corridor between hole rows is narrow (the capsule system), straight where it is wide (round-hole grids). Stepped always steps around the holes, and on the capsule system it steps the vertical seams too. These keep at least 7.4 mm of wall to every slot (with the default 0.2 mm hole clearance). Strips follow their steps, and puzzle tabs sit on their straight stretches, pointing either way, and where those have no room, on a step, pointing up. Pieces get up to 20 mm wider, so a board may need a few more. On curved outlines (SVG and Text boards) and small beds, Stepped can also leave more small pieces, pieces without room for a wall anchor or a label and seams with no room for tabs or a strip than Auto; the Issues tab names them. Auto and Straight keep vertical seams straight, and on every other pegboard type they stay straight with any seam shape. Straight gives straight horizontal seams; on round-hole grids that is what Auto does anyway. Where the corridor between hole rows is too narrow to keep the full edge margin beside the holes but still leaves at least 2 mm of wall, Straight gives narrow straight seams through it: on the capsule system, and on any Custom type with such a corridor. On the capsule system they run through the 5 mm corridor, about 2.5 mm from the slot ends (2.4 mm with the default 0.2 mm hole clearance); the board’s outer edges, solid areas and letter openings keep the full edge margin. Short bridge strips, 10 × 50 mm by default and one every 40 mm in the 15 mm vertical corridors, are glued across these seams on the back (Bridge strips on straight seams). Below 2 mm of wall, or where a straight seam would cut through holes (possible with a Custom type), Straight falls back to the Auto seams (stepped horizontal seams), with a warning.
Allow rotationDefault On: Lets a piece turn 90° on the bed when that fits better. Pieces are never flipped: the front always prints face down.

On SVG and Text boards, with their curved outlines and letters, narrow straight seams have two more limits. Where a straight seam would cut a thin sliver off the outline, the app first tries other straight seam positions. If straight seams would still cut slivers off, leave out holes that stepped seams keep (for example beside raised letters) or leave a piece that nothing can hold, the app uses the Auto seams instead, for the whole board or a separate part of it, and shows a warning. On signs with raised letters, Straight also gives way to the Auto seams when those give more pieces room for a wall anchor or need a narrower margin around the letters, or when straight seams would cut off a sliver or leave out holes that stepped seams keep, even if that takes a wider margin. And a piece that is very thin next to a straight seam, or shares very little seam with its neighbour, may get no bridge strip: the Issues tab names the pair (“No room for a spline strip”), and you glue that seam edge to edge instead.

Joints

How neighbouring pieces hold together. Assembly steps and glue advice are in Joining pieces.

MethodDefault Spline strip: Spline strip — a shallow recess on the back of both pieces takes a printed strip that you glue in. Flush front, no visible hardware, very stiff; the recommended joint. Puzzle — dovetail tabs in the hole-free corridors; pieces press together and can be assembled on the wall, glue optional. Butt — plain edges; each piece relies on its own wall anchors. With puzzle or butt joints, a piece that would be left without an anchor gets glued spline strips on its seams anyway (Strips the app adds). Straight seams on the capsule system take bridge strips instead of a full-length strip or tabs: with spline strips and with puzzle joints (no tab fits the 5 mm corridor, so only the vertical seams get tabs), and with butt joints only where a piece would otherwise hang loose.
ClearanceDefault 0.15 mmRecommended 0.1–0.15 (spline), 0.15–0.2 (puzzle)Range 0–1 mm: Gap per side between mating features. Increase by 0.05 mm steps if strips or tabs are too tight on your printer.
Spline widthDefault 10 mmRange 4–60 mm: Width of the strip, and of the bridge strips across straight seams. 10 mm fits inside the 15 mm capsule corridors with material to spare; wider strips are possible on round-hole grids.
Spline depthDefault 2.2 mmRange 0.8–10 mm: Depth of the recess and thickness of the strip. 2.2 mm leaves 2.8 mm of a 5 mm capsule panel in front — enough to stay flat and hide the strip. At least 1.2 mm always stays in front, so on thin boards (3 mm, 1/8″) the app makes the recess shallower.
Puzzle tab sizeDefault 8 mmRange 3–40 mm: Size of each dovetail. Tabs are only placed where they don’t come near a hole.
Puzzle spacingDefault 60 mmRange 20–400 mm: Target distance between tabs along a seam.

Wall mounts

Countersunk screw anchors are built into the back of the pieces: a boss that sets the standoff, a 90° countersink for the screw head, and a counterbore above it that a printed cap closes flush with the front. Anchors and separators only sit in the gaps between holes, clear of where hooks reach behind the board, so they never cost you a hole. These settings live in the Mounting tab; the mounting guide explains the three placement modes, the load check and the drilling guide in detail.

Section through a wall anchor: the screw head seats 5.5 mm from the wall; a cap hides it.

Screw mountsDefault On: Turn off only if you will fix the board another way (for example a French cleat you design yourself).
Anchor placementDefault Automatic (by load): Automatic (by load) puts the anchors of all pieces on a few shared horizontal rows with shared positions, sized for the load: each row is one level line to drill. Fixed grid places exactly the number of level rows and anchors per row you choose. Manual lets you place every anchor in the Plan view — on studs, for example; each one snaps to the nearest hole-safe spot. Projects made with the older Per piece (legacy) layout keep it.
At least one anchor per pieceDefault On: Automatic only. On gives every piece its own anchors (two with butt joints). Off places only the anchors the load and spacing need — 12 instead of 24 on the default board — and the pieces without one hang on their neighbours through glued strips.
Level rows × Anchors per rowDefault 3 × 4Range 1–20 × 1–40: Fixed grid only. Rows are spread from the bottom of the board to the top, the anchors of every row share the same positions, and each anchor takes the nearest free spot on its row.
Manual anchorsDefault NoneRange 0–400: Manual only. Placed, dragged and removed in the Plan view; Start from automatic layout copies the automatic anchors as a starting point. Anchors the app can’t use are listed with the reason.
Wall materialDefault Masonry: Masonry, Wood or Drywall. Sets the working load counted per anchor (15, 20 or 3 kg) and the hardware hint. On drywall the app reminds you to use metal cavity anchors or the studs.
Expected loadDefault 25 kg/m²Range 2–150 kg/m²: Light 10, Medium 25 or Heavy 50 kg per square metre of board, or your own value. In Automatic mode the layout adds anchors until twice this load plus the board’s weight is covered; with a fixed grid or manual anchors it is checked against what they carry. The Mounting and Summary tabs show capacity against load.
Max. anchor spacingDefault 400 mmRange 120–1200 mm: Automatic only (advanced): largest distance between two anchors in a row.
Max. row spacingDefault 450 mmRange 120–1200 mm: Automatic only (advanced): largest distance between two rows.
Mounts per pieceDefault AutoRange 0–12: Per piece (legacy) only. Auto puts 2 anchors near the top corners of each piece, or 4 on pieces of at least 170 × 170 mm; Fixed forces a number.
Screw capsDefault On: Exports a small cap per anchor that presses into the counterbore and hides the screw.
Shank ØDefault 4 mmRange 2–8 mm: Advanced. Diameter of the screw. The hole gets the screw clearance on top.
Head ØDefault 10 mmRange 4–20 mm: Advanced. Countersink diameter. Ø 10 mm takes the heads of all common 4–5 mm wood and chipboard screws (7.5–9 mm); smaller heads simply sit slightly deeper.
Head angleDefault 90°Range 60–120°: Advanced. Included angle of the countersink. 90° matches standard countersunk screws.
Material under headDefault 5.5 mmRange 2–20 mm: Advanced. Plastic between the end of the countersink and the wall. It is what the screw clamps; 5–6 mm is strong without needing longer screws.
Hole clearanceDefault 0.4 mmRange 0–1 mm: Advanced. Added to the shank so the thread never bites the plastic.

With the defaults, use 4 × 45 mm countersunk screws with 6 mm wall plugs in masonry. The default 1200 × 800 mm board hangs on 24 anchors in 4 level rows; with At least one anchor per piece off, or with the default 3 × 4 fixed grid, on 12 anchors in 3 rows.

Separators

Separators are feet on the back that hold the board at a fixed distance from the wall — the standoff — so hooks can reach behind it. They sit on the same hook-safe spots as the anchors and are spread so that every point of a piece is within half the spacing of a support, favouring the bottom edge, the seams and the corners.

SeparatorsDefault On: Keep them on unless the board will sit on a frame or battens of your own.
Wall distanceDefault By pegboard typeRange 6–40 mm: Wall-to-back distance. Picking a pegboard type sets its recommended value, and the value stays within the type’s range: 10 mm on the capsule system (from 6 mm — printed clips need only a few millimetres), 12.7 mm (½″) on round-hole boards (10–20 mm — wire hooks need at least ½″). The Custom type follows its hole shape. See Standoff.
Foot diameterDefault 10 mmRange 4–40 mm: Size of each foot. Bigger feet spread the load on soft walls. Between dense holes a foot is made smaller so it stays clear of them.
Max. spacingDefault 140 mmRange 40–600 mm: Largest distance between two supports (separators and anchors). Lower it for heavy tools or thin, light-profile panels.

Graphics

Add text and SVG artwork anywhere on the board as colour inlays in the front face. Each graphic has a position, a width (text uses its font size), a rotation and a colour — or, for SVGs, its original colours.

Solid areaDefault Off: Removes the holes under the graphic, plus the edge margin, so it reads cleanly. Leave it off to keep every hook position.

Graphics follow the seams like everything else: a logo that spans two pieces is split between them and lines up again on the wall.

Labels and assembly map

Piece labelsDefault On: Adds a short label (A1, A2, …), engraved into the back of every piece. The same labels appear on the assembly map included in the ZIP, together with the seams and the drilling guide for the anchors.

Pegboard type, panel and colours

Pegboard type, hole clearance, board thickness, light profiles, border paint and hole rings are covered in Settings every workflow shares.

Tips for big walls

Measure twice. Enter the free wall area, then check the fitted board size the app reports before exporting.
Use brick layout for anything more than two rows of pieces.
Prefer spline strips for stiffness; switch to puzzle joints if you want to assemble directly on the wall.
Drill fewer holes. With glued strips holding the pieces together, switch off At least one anchor per piece in the Mounting tab to keep only the anchors the load needs: a 3000 × 2000 mm board goes from 117 to 78 anchors. On a stud wall, use Manual placement and put the anchors on the studs.
Print one piece first. A single export contains every piece; print one of them, check how your hooks fit and that it lies flat, then print the rest.
Watch the filament estimate. It assumes a completely solid print, so real use with 15–25 % infill is lower — but a full wall is still counted in kilograms. The Pockets profile lowers the estimate by about 20–25 %.
